INSTRUCTION
MANUAL
FOR SPEEDOTRON
BROWN LINE
EQUIPMENT
Speedotron power supplies are equipped with arc-protected outlets. However, as with
any electrical equipment, arc-over (an electrical discharge between two physically dis-
connected electrical terminals) is a possibility. When light cables, flash tubes or power
cords are improperly seated, arc-over may occur. Also, if your light unit or power supply
malfunctions, or the power cord or the internal wiring in the studio is improperly termi-
nated or defective, there is a chance of arc-over when connecting or disconnecting light
units. Severe power supply damage and operator injury may result if arc-over occurs.
That is why in spite of the arc-protection feature of Speedotron power supplies, you
should always make sure your Model and Power switches are off when disconnecting or
connecting light units. Plug sync extension into Sync socket and connect the other end
to a PC cord designed for your camera or lens. The sync extension supplied with the
power supply accepts the standard AC twin-blade type sync connector. A standard AC
to PC sync cord will be required to connect the camera to the power supply's sync
extension.
GENERAL POWER SUPPLY INSTRUCTIONS
For maximum equipment life and for safe, dependable operation of power
supplies we advise you to follow these general rules.
Unpack equipment carefully. Examine all packing material. Should you notice any break-
age or defect, notify the dealer and carrier (if shipped to you) immediately. Then please
read all instructions before assembling your flash system in order to avoid damage to
your equipment or injury to yourself.
Before doing anything with the power supply make sure that the Model and Power
switches are in the off position.
Connect light head cable(s) to the Light Unit Outlet(s) on the power supply, selecting
the appropriate outlets for the desired power level.
A slave tripper (Speedotron #23510) may be installed in the Sync socket (in place of the
sync extension) to fire the power supply. If the power supply fails to flash when exposed
to another light source with the slave installed in the Sync socket, remove the slave,
rotate it 180° and reinstall it in the socket.
All Brown Line light units can handle at least 400 watt-seconds, and specific units are
designed for a maximum of 1200 or 1600 watt-seconds. For power supplies that can pro-
duce more than 400Ws of power, you must be very careful that the flash tube you are
using in your light unit can handle all the available power. Never subject a flash tube to
more watt-seconds than it is designed to handle. If you are not sure that your flash
tube can handle the power provided by the set-up you are using, check pages 25 and 26
in addition to the Power Distribution Chart on the side of your power supply. We recom-
mend that you purchase at least one light unit that will accept the full output of the
power supply.
Connect AC power cord into Power Input on power supply. A 3-terminal ground power
plug is utilized on Brown Line power supplies. For maximum performance and safety, it is
strongly suggested that the 3-terminal cord supplied with the power supply be properly
utilized and properly terminated at the main source of incoming power. Always use a
three-wire ground power cord and a properly grounded wall outlet with all Speedotron
power supplies. Failure to do so may cause the power supply to intermittently misfire.
We do not recommend using an adapter and installing into a 2-blade
outlet.
To connect light units, align the light unit plug with the power supply outlet and apply
even pressure while pushing. Black colored light unit connectors are of the “quick
release” type that only require pushing the connector firmly until it is fully seated. Silvery
colored light unit connectors must be threaded until they are fully seated. Both types
prevent accidental cable removal. Make sure all light unit cables are fimly seated to pre-
vent connector damage. Tape all cables to the floor and keep them out of the pathways
to prevent accidents.
Once the light units are properly assembled and installed, the power cord is installed
and the sync extension is connected, turn the Power switch on.
Now refer to the Operating Instructions section of this manual for information regarding
the proper use of your particular power supply.
Never attempt to make repairs to your Speedotron equipment. All electronic flash
systems operate on high voltage and high power. It is very dangerous to open a
power supply.
Never install light units while the power supply is turned on. Never insert or remove
flash tubes while the light unit is connected to the power supply. Be sure flash tubes
are fully seated into light unit sockets. (Read instructions in the Light Units section of
this manual for more information on light unit assembly and operation.)
In order to maximize the life of the power supply it is recommended that
the capacitors be "formed" when a pack is not in use for 30 days or more.
All that is required of the user is to turn on the power supply for about 10
to 20 minutes each month. This simple procedure prevents premature
failure by maintaining the "elasticity" of the capacitors.

Power Model
Operation of the D604, D1204 and D1604 power supplies is simple and straight for-
ward. This sequence of operation is suggested for maximum life and dependability.
Make sure that the Model and Power switches are in the off position and the Push to
Reset button is fully depressed into its socket. Connect light head cable(s) to the Light
Unit Outlet(s) on the power supply. The outlets are wired in parallel so it does not
matter in what sequence light head cables are connected.
Never connect or disconnect light units while power is on. Do not insert or remove
flash tubes while power is on. Your Brown Line power supply is equipped with arc-pro-
tection, but should your light unit or power supply malfunction, or the power cord, or
even the internal wiring in the studio be improperly terminated or defective, the chance
of arc-over when connecting or disconnecting light units is greatly increased. Severe
power supply damage and operator injury may result if arc-over occurs when light units
are being disconnected or connected. To prevent this, you should always turn the power
supply off when disconnecting or connecting light heads.
Never subject a flash tube to more watt-seconds than it is designed to handle.
MW3 and M90 series (non-”Q”) light units have a maximum rating of 400Ws, while “Q”
versions are rated at 1200Ws. M11 light units are rated at 1200Ws* (with new MW9H
flashtubes) and M11Q light units are rated at 2400Ws. We strongly recommend that at
least one light unit in your system is capable of handling the maximum output of your
power supply. If you are not sure if your flash tube and light unit can handle the power
provided by the set up you are using, check pages 25 and 26 and the Power Distribution
Chart on the side of your power supply.

GENERAL DESCRIPTION OF CONTROLS
Power – turns power supply on and off (flashes light units when turning off).
Model – turns model lamp(s) on and off.
Symmetrical/Asymmetrical – controls power distribution. In the symmetrical position,
power is split equally between all lights. In the asymmetrical position, power is
distributed unequally and modeling lamp brightness on light units in outlets 3 and 4
is reduced.
Full/Half (on D604) or Full/Half/1/4 (on D1204 and D1604) – controls the total amount
of power delivered to light unit outlets.
Ready/Push to Flash – combination ready light and test flash button. Illuminates in
green to indicate when power supply has recycled to 85%. Pressing the button
when illuminated triggers the flash for testing or open flash applications.
Audible Recycle – controls audible ready tone (on/off).
Connect AC power cord into Power Input on power supply, then plug into a properly
grounded outlet. Use proper 3-conductor grounded cord for operator safety and to
reduce self-firing and misfiring caused by static electricity. Set Full/Half/1/4 switch as
desired (Full/Half switch on D604). This switch reduces the total output of the power
supply. Do not switch the Full/Half/1/4 switch until ready light is illuminated. Failure to
follow this procedure may result in damage to the switch.
Plug sync connector into Sync socket and connect the other end to PC cord for camera.
Once the camera is connected, tripping the shutter will automatically trigger the flash.
Power On – green LED illuminates when power switch is turned on.
Hi-Temp – red LED lights, alarm tone sounds, when internal heat becomes excessive.
Sync – socket for sync extension or slave.
Push to Reset – resets circuit breaker. Circuit breaker disables power supply in case of
malfunction.
A slave tripper (Speedotron #23510), may be inserted into the Sync socket in place of
the PC cord. In this mode of operation, the slave will activate the power supply when it
senses a bright flash of light from another light source. If the power supply fails to flash
when exposed to another light source with the slave installed in the sync socket, it may
be necessary to remove the slave, rotate it 180° and reinstall it into the Sync socket.
Power Input – socket for AC power cord.
Light Unit Outlets (4) – sockets for connecting from one to four light units to power
supply.
*New MW9H flashtubes supplied with M11 light units handle up to 1200Ws.
The MW9M flashtubes have a maximum capacity of 1000Ws.

Turn on Power and Model switches. Wait until the green Ready/Push to Flash illumi-
nates and press to check if the unit is operational. The light unit(s) should flash instantly
when this button is pressed. If you wish to check the function of each individual light unit,
we recommend that you turn off the Model switch and hold your hand in front of (not
inside) the light unit to be tested. When you fire the unit you will feel the heat of the
flash. This method is suggested because it is often difficult to determine by sight if one
of the lights has failed to flash.
POWER DISTRIBUTION TABLES
On the side of the D604, D1204 and D1604 power supplies there is a Power Distribution
Table based on the full power setting. These tables should be used as guides for deter-
mining various lighting possibilities, guide numbers and exposures when using consistent
flash tubes and reflectors. When different flash tubes and/or reflectors are used actual
light output will vary, producing as much as a full f/stop discrepancy with the table.
Brown Line '04 power supplies, feature symmetrical and asymmetrical operation.
Symmetrical output means all light units share equal output. To determine power levels,
divide the maximum output by the number of light units to be used. In asymmetrical
mode, outlets 1 and 2 receive a greater portion of the total output than outlets 3 and 4.
(For specific power distribution refer to the charts below for the number and configura-
tion of the lights to be used.)
The D604, D1204 and D1604 power supplies are equipped with an audible ready
signal (may be turned off) and high temperature alarm. A short audible tone along with
a green Ready/Push to Flash light indicates that the power supply has recycled to 85
percent (ANSI standard). For very critical exposures, waiting several seconds after the
green Ready/Push to Flash light illuminates will ensure that the power supply is at 100
percent power. If the beep should prove distracting, depress the Audible Recycle switch
to eliminate this short tone. The green Ready/Push to Flash light will still continue to
illuminate.

Prolonged rapid flashing or storage in a high temperature environment (like the trunk of
a car) or extended use in extremely warm environments may eventually produce enough
heat to set off a steady alarm tone and red Hi-Temp LED indicator. The power supply
should be turned off at the Power switch because continued use may cause severe dam-
age. When the power supply has sufficiently cooled, normal operation may be resumed.
(If the power supply is not turned off, the alarm will not clear.)

When disassembling the system, turn off Power and Model switches first. When the
Power switch is turned off, the power supply will discharge by flashing all light units.
Placing the Full/Half/1/4 switch into the full position before turning off Power will
ensure that all capacitors are discharged. If the power supply should be inadvertently
switched off at a lower power setting, DO NOT immediately switch to full power!
Damage to the switch may result. Wait at least 10 seconds before operating the
Full/Half/1/4 switch. Unplug the power cord and disconnect the light head cable(s).

Power
Operation of Brown Line power supplies is simple and straight forward. It is suggest-
ed that this sequence of operation be utilized for maximum life and dependability.
Make sure that the Model and Power switches are in the off position and the Push to
Reset buttons are fully depressed into their sockets. Connect light head cable(s) to the
Light Unit Outlet(s) on the power supply. The outlets are wired in parallel so it does not
matter in what sequence light head cables are connected.
Never connect or disconnect light units while power is on. Do not insert or remove
flash tubes while power is on. Your Brown Line power supply is equipped with
arc-protection, but should your light unit or power supply malfunction, or the power
cord, or even the internal wiring in the studio be improperly terminated or defective, the
chance of arc-over when connecting or disconnecting light units is greatly increased.
Severe power supply damage and operator injury may result if arc-over occurs when
light units are being disconnected or connected. To prevent this, you should always turn
the power supply off when disconnecting or connecting light heads.
Never subject a flash tube to more watt-seconds than it is designed to handle. MW3
and M90 series (non-”Q”) light units have a maximum rating of 400Ws, while “Q” ver-
sions are rated at 1200Ws. M11 light units are rated at 1200Ws* (with new MW9H
flashtube) and M11Q light units are rated at 2400Ws. We strongly recommend that at
least one light unit in your system is capable of handling the maximum output of your
power supply. If you are not sure if your flash tube and light unit can handle the power
provided by the set up you are using, check pages 25 and 26 and the Power Distribution
Chart on the side of your power supply.

DESCRIPTION OF CONTROLS
Power – turns power supply on and off (flashes units when turning off D802 or D402).
Model – turns model lamp(s) on and off.
Connect AC power cord into Power Input on power supply, then plug into a properly
grounded outlet. Use proper 3-conductor grounded cord for operator safety and to
reduce self-firing caused by static electricity. Set Full/Half switch as desired. This switch
reduces the total output of the power supply. The difference between the “full” and
“half” settings is one f-stop. After flashing, do not switch the Full/Half switch until ready
light is illuminated, or until at least ten seconds after turning off unit. Failure to follow
this procedure may result in damage to the switch.
Symmetrical/Asymmetrical – controls power distribution. In the symmetrical position,
power is split equally between all lights. In the asymmetrical position, power is
distributed unequally and model lamp brightness on light units in outlets 3 and 4 is
reduced.
Full/Half – controls amount of power delivered to light unit outlets.
Ready/Push to Flash – a combination ready light and test flash button. Illuminates to
indicate when power supply has recycled to 85%. Pressing the button when
illuminated triggers the flash for testing or open flash applications.
Sync – socket for sync extension or slave.
Plug sync connector into Sync socket and connect the other end to PC cord for camera.
Once the camera is connected, tripping the shutter will automatically trigger the flash.
Push to Reset – resets circuit breaker. Circuit breaker disables power supply in case of
malfunction.
Power Input – socket for AC power cord.
Light Unit Outlets (4) – sockets for connecting from one to four light units to power
supply.
A slave tripper (Speedotron #23510), may be inserted into the Sync socket in place of
the PC cord. In this mode of operation, the slave will activate the power supply when it
senses a bright flash of light from another light source. If the power supply fails to flash
when exposed to another light source with the slave installed in the sync socket, it may
be necessary to remove the slave, rotate it 180° and reinstall it into the Sync socket.
*New MW9H flashtubes supplied with M11 light units handle up to 1200Ws.
The MW9M flashtubes have a maximum capacity of 1000Ws.

Turn on Power and Model switches. Wait until the Ready/Push to Flash illuminates and
press the button to check if the unit is operational. The light unit(s) should flash instantly
when this button is pressed. If you wish to check the function of each individual light unit,
we recommend that you turn off the Model switch and hold your hand in front of (not
inside) the light unit to be tested. When you fire the unit you will feel the heat of the
flash. This method is suggested because it is often difficult to determine by sight if one
of the lights has failed to flash.
When disassembling the system or changing the position of a light unit connector in any
outlet, it is a good habit to set the Full/Half switch to full first, then turn off Model and
Power switches prior to disconnecting light units. If this procedure is not followed, allow
10 seconds between turning the Power switch off and adjusting the Full/Half switch.
DO NOT immediately switch to full power! Damage to the switch may result.
The D402 and D802B power supplies will flash their light units when turned off. Placing
the Full/Half switch on the D402 and D802B into the full position before turning off
Power will ensure that all capacitors are discharged.
One light:
Symmetrical mode in any outlet, will receive 400Ws.
Asymmetrical mode in outlets 1 or 2, will receive 400Ws;
when using outlets 3 or 4 output is 300Ws.
Two lights: Symmetrical mode, all outlets share an equal amount of power.
Two lights each receive 200Ws (400Ws divided by 2).
Asymmetrical mode
Combination 1: one light in outlet 1 or 2 receives 200Ws;
the second light in outlet 3 or 4 receives 100Ws.
Combination 2: in outlets 1 and 2 receive 200Ws each.
Combination 3: in outlets 3 and 4 will receive 100Ws each.
Following the table will quickly illustrate other combinations that are possible with
up to four light units on the D402.

Never connect or disconnect light units while power is on. Do not insert or remove
flash tubes while power is on. Your Brown Line power supply is equipped with arc-pro-
tection, but should your light unit or power supply malfunction, or the power cord, or
even the internal wiring in the studio be improperly terminated or defective, the chance
of arc-over when connecting or disconnecting light units is greatly increased. Severe
power supply damage and operator injury may result if arc-over occurs when light units
are being disconnected or connected. To prevent this, you should always turn the power
supply off when disconnecting or connecting light heads.

Connect power supply cord into a 3-wire grounded AC outlet. This reduces misfires and
self-firing caused by static electricity.
Plug sync connector into Sync socket and connect the other end to PC cord for
camera. Once the camera is connected, tripping the shutter will automatically trigger the
flash.
D202 Power Distribution Table
A slave tripper (Speedotron #23510), may be inserted into the Sync socket in place of
the PC cord. In this mode of operation, the slave will activate the power supply when it
senses a bright flash of light from another light source. If the power supply fails to flash
when exposed to another light source with the slave installed in the sync socket, it may
be necessary to remove the slave, rotate it 180° and reinstall it into the Sync socket.

Turn on Power and Model switches. Wait until the amber Ready/Push to Flash
illuminates and press the button to check if the unit is operational. The light unit(s)
should flash instantly when this button is pressed. If you wish to check the function of
each individual light unit, we recommend that you turn off the Model switch and hold
your hand in front of (not inside) the light unit to be tested. When you fire the unit you
will feel the heat of the flash. This method is suggested because it is often difficult to
determine by sight if one of the lights has failed to flash.

One light:
Symmetrical mode in any outlet, will receive 200Ws.
Asymmetrical mode: outlet 1 will receive 200Ws;
outlet 2 outputs 150Ws.
The D202 has symmetrical and asymmetrical power distribution. The two light units are
connected in parallel when the symmetrical/asymmetrical switch is in the symmetrical
position. With the switch in the asymmetrical position power will be distributed as shown
by the power distribution table on the next page or on the side of the power pack.
Two lights: Symmetrical mode, both outlets share an equal amount of power.
Two lights each receive 100Ws (200Ws divided by 2).
Asymmetrical mode: light in outlet 1 receives 100Ws;
the light in outlet 2 receives 50Ws.

To connect light units, align the light unit plug with the power supply outlet and apply
even pressure while pushing. Black colored light unit connectors are of the “quick
release” type that only require pushing the connector firmly until it is fully seated. Silvery
colored light unit connectors must be threaded until they are fully seated. Both types
prevent accidental cable removal. Make sure all light unit cables are fimly seated to pre-
vent connector damage. Tape all cables to the floor and keep them out of the pathways
to prevent accidents.
BROWN LINE LIGHT UNITS
General Instructions and Information
The Speedotron Brown Line light units described here may be used with any Speedotron
Brown Line power supply using the five-pin MS outlet. All light units are supplied with a
20' wired-in cable.
Speedotron power supplies are equipped with arc-protected outlets. However, as with
any electrical equipment, arc-over (an electrical discharge between two physically dis-
connected electrical terminals) is a possibility. When light cables or flash tubes are
improperly seated, arc-over may occur. Also, if your light unit or power supply malfunc-
tions, or the power cord or the internal wiring in the studio is improperly terminated or
defective, there is a chance of arc-over when connecting or disconnecting light units.
Severe power supply damage and operator injury may result if arc-over occurs. That is
why, in spite of the arc-protection feature of Speedotron units, you should always make
sure Power is off when connecting or disconnecting light units.
Unpack and examine all equipment carefully. Should you notice any breakage or defect,
notify your dealer (and the carrier if it was shipped to you) immediately. The flash tube(s)
and model lamp(s) are packed in their original cartons. This affords sufficient protection
and reduces the incidence of breakage during shipping. Make sure all packing materials
are removed before using. This includes the pipe cleaners (used as packing material)
inside some flash tubes.
Install flash tubes first. Always handle lamps and flash tubes with care. Because they can
break if put under stress, handle them cautiously. Don’t touch glass surfaces with your bare
hands. If your fingers come in contact with the glass of the model lamp, wipe off carefully
with alcohol. When removing or replacing lamps and tubes, always disconnect light units
from power supply. Allow lamps to cool before handling. For instructions on how to insert
model lamps into specific units, see the unit descriptions on the following pages.
All Brown Line light units fit on top of 5/8" light stands. MW3U and MW3UCC accept
umbrellas with shafts up to 3/8". MW3R and MW3RCC light units include an adaptor to
fit onto 3/8" light stands.
Turn on power supply, wait for Ready light, then press Push to Flash button to verify
proper operation. The model lamp may be turned on or off by the switch located on the
top of the light unit assembly (insure that the Model switch at power supply is on).
Flash tubes must be inserted into the sockets all the way. Flash tube pins must align with
the flash tube socket to be inserted. Apply gentle pressure. A slight rocking motion may
be necessary when installing larger flash tubes. New flash tubes and sockets fit very
tightly. Be sure all flash tubes and model lamps are fully seated into light unit sockets.
For maximum performance and life, the model lamp should be used only when
necessary and turned off after initial set-up or focusing is done. Although convection
cooling is more than ample for normal usage, turning off the model lamp will eliminate
heat and enable the light unit to run cooler, extending the life of all components.
It is important to observe the maximum watt-seconds rating of these light units. Never
subject a flash tube to more watt-seconds than it is designed to handle. MW3 and
M90 series (non-”Q”) light units have a maximum rating of 400Ws, while “Q”
versions are rated at 1200Ws. M11 light units are rated at 1200Ws* (with new MW9H
flashtubes) and M11Q light units are rated at 2400Ws. We strongly recommend that at
least one light unit in your system should be capable of handling the maximum output of
your power supply. If you are not sure that the flash tube in your light unit can
handle the power provided by the set up you are using, check the following pages and
the Power Distribution Chart on the side of your power supply. Failure to observe this
precaution could drastically shorten the life of your flash tubes.
After extended use or after transporting your system, inspect flash tubes for cracks and
any unusual darkening (arc-over) around the tube sockets. If cracks or darkening are
noted the flash tube is, most likely, near the end of its duty cycle. Cracked tubes will
probably misfire. The normal duty cycle is 100,000 flashes for the majority of Speedotron
Brown Line flash tubes.
Be sure replacement flash tubes are designed for the watt-second output requirements
of Speedotron light units. Applying too much power severely shortens the life of flash
tubes, may cause fine cracks to develop in the tube that may cause tube failure or, in the
most extreme case, may cause the tube to shatter. For this reason, we suggest you
always use Speedotron flash tubes and model lamps to insure safe and dependable
operation.
Connect light cable(s) to the Light Unit Outlet(s) on the power supply. Never connect or
disconnect light units while Power is on. Do not insert or remove flash tubes or model
lamps while Power is on.
*New MW9H flashtubes supplied with M11 light units handle up to 1200Ws.
The MW9M flashtubes have a maximum capacity of 1000Ws.

TROUBLE-SHOOTING
GENERAL MAINTENANCE AND CARE
System will not work at all; no flash.
Check that sync cable, AC power cord and light unit cables are firmly and properly
attached. Check that the flash tube is firmly seated. Check that Power switch is on.
With metal camera bodies, you may be required to polarize the camera sync cable and
the power supply sync extension in order to avoid possible misfires resulting from a
build-up of static electricity. This is done by touching any unpainted metal part of the
power supply with the unpainted part of the camera, or better still, with the outer shell
or the grounded part of the sync cable with all sync cords attached. If the unit flashes,
the plug on the sync cable should be reversed and then marked for future reference.
Test fire the camera after reversing the sync extension cable (PC to power supply). If the
unit still does not fire, reverse the PC to camera connection and try again. The trigger
current is very low and is measured in microamperes, so it is impossible to even feel any
shock when touching these contacts.
All Speedotron Brown Line equipment is ruggedly built. Nevertheless, it should be
treated with the same care given to other pieces of quality photographic equip-
ment. To protect the user, all Speedotron equipment is designed to be safe when
used in accordance with instructions. To assure the maximum in safe, dependable
service, the following guidelines should be carefully observed.
• Avoid kinking or pulling cables. Disconnect cables by pulling on the plug only. Never
pull plugs out by the cable. Light cables as well as sync cords and AC power cords
should be occasionally checked for wear, cracks, separation between cable and plug, and
for indications of arc-over.
• Do not wrap the light unit cables around the light units. Coiling cables tightly stresses
the internal wires and may lead to premature cable failure. If possible, keep the coil
diameter at least 10 inches.
Occasional failure of all light units to flash.
Check sync cable and light unit cable connections. Make sure that the Ready indicator is
illuminated before attempting to fire unit.
• If a cable becomes frayed, the insulation damaged, or the connectors bent or broken,
have them repaired immediately.
Occasional failure of one light unit only.
Check light unit cable connection. Inspect the cable. Check flash tube. Make sure that
• Keep all connectors, plugs and sockets free of dust, moisture and corrosion.
the Ready/Push to Flash indicator is illuminated before attempting to fire unit.
• Do not connect or disconnect light units or insert or remove flash tubes while the
power supply is on.
Reduced light output.
Check to see if Full/Half/Low or Full/Half/1/4 switch is in right position. Check flash tube;
check power supply by comparing to similar pack with same light units if possible.
• When using your equipment, be sure all cable, sync, power and flash tube connections
are completely and properly installed.
Flash tube glows after firing (afterglow); will not flash again until glow is gone.
If confined to one light unit, check flash tube by substitution. If it continues or all heads
afterglow, power supply is at fault. If this is the case, turn power supply off immediately!
Power supply needs repair.
• Do not attempt to make repairs to your Speedotron equipment yourself. It is very
dangerous, and will void your warranty. Consult your dealer regarding authorized
service in your area, or return the equipment to Speedotron.
• When you are not using your equipment, it is recommended that you store it in a dry
place. Equipment should be charged up and flashed a few times at least once a month.
This will keep your equipment in top working condition for many years.
Full/Half/Low or Full/Half/1/4 switch has no effect on recycle time or light output.
Power supply needs repair.
Circuit breaker on power supply pops.
• With your light unit disconnected, occasionally clean the interior surface of the
reflector. Carefully remove the flash tube, and clean the glass cover. Only in this way will
you conserve a consistent color temperature and light output. Dirt and dust deposits on
the tube and reflector act like a filter to alter color.
Check that all cables on power supply and light units are properly connected. Also check
for afterglow. If a circuit breaker blows, it is an indication that something is wrong.
Normal operation will not blow circuit breakers.
Circuit breaker or fuse in studio blows.
Be sure AC line is rated for a minimum of 10 amperes and that high amperage
electrical equipment is not operating on the same AC line.
• Never handle the quartz halogen model lamps with your bare hands. Use tissue or
packing materials when installing and removing. The natural oils from your skin may
cause the glass surface to heat unevenly and cause early failure. When removing these
lamps allow sufficient cooling time before touching.
Important: When checking power supplies, light units and cables, be sure that Power is
off. Look for blackened, discolored or burned pins and sockets. If a Light Unit Outlet on
the power supply is burned, blackened or discolored, it must be replaced before it is
used. It could damage light units that are connected to it. Check that cables are not
loose or frayed.
• To extend their life, the model lamp circuit should be turned off after set-up and
focusing.

FLASH DURATION
GUIDE NUMBERS
Flash duration of a Speedotron Brown Line system will vary with the type of flash tube,
the amount of power outputted and the number of light units connected to the power
supply. For example, a D402 system with two M90 light units and two MW3R light units
will have four MW3-1 flash tubes and a 400Ws power supply. When set to full power
each flash tube will output 100 Ws with a flash duration of 1/1500 second.
Guide numbers provide a starting point in calculating the proper exposure for pictures
taken with flash. A guide number is a constant numerical value (for a given film
speed/ISO) determined by multiplying the light source-to-subject distance by the f-stop
in use on the lens. Consequently, dividing a given (known) guide number by the light
source-to-subject distance will yeld the proper f-stop. For example, if the given guide
number is 110 and the light source to subject distance is 10 feet, the f-stop required for
proper exposure is f/11.

Important note: Guide number values provide a general starting point for exposure
determination and vary depending on a myriad of factors such as power supply differ-
ences, surrounding area reflectance, flash tube differences, etc. In some instances such
as extreme close-up and macro applications guide numbers will not provide accurate
exposure information. All guide numbers are approximations and we recommend that
test shots be produced to insure exposure accuracy.
Flash duration is measured from 1/2 peak light output to 1/2 light peak output as
illustrated below:
Peak
The guide numbers bellow are based on exposure from one light only, on axis with an
exposure index of ISO 100 in feet. The information supplied in the chart bellow is most
accurate for use in small, light colored rooms. For large or dark colored rooms it may be
necessary to open the lens 1/2 f-stop. For rooms which are both large and dark colored
it may be necessary to open up as much as one full f-stop.

Light will continue to be produced for about five times the flash duration but will add
little to the exposure. This will not affect action stopping abilities for most normal
contrast subjects.

SPEEDOTRON’S LIMITED WARRANTY
Speedotron guarantees to repair or replace, free of charge, any part or parts (except for flash tubes
and modeling lamps) found by factory inspection to be defective due to faulty material or workman-
ship, provided the equipment is returned to our factory prepaid. The period of warranty is two years
from the date of original purchase. Flash tubes, which are warrantied by independent manufactur-
ers, are covered for a period of one year only, and the length of manufacturer warranties on model-
ing lamps varies. The manufacturers’ warranties covering flash tubes and modeling lamps are for
defective merchandise only, and do not cover tubes that are cracked or broken.
The Speedotron two-year warranty does not apply to equipment which has been abused, cracked
or broken in shipping, resold or rented (without written permission from Speedotron Corporation),
which has the serial number removed or defaced, which has been modified or repaired by an unau-
thorized person, or which has been purchased from any source other than an authorized
Speedotron dealer. A copy of the original sales receipt from an authorized Speedotron dealer is
required at the time of warranty service.
Speedotron shall not be liable for any injury, loss or damage, direct or consequential, arising from
the use or inability to use the product. Prior to use, the purchaser shall determine the suitability of
the product for the intended use and assume all risks and liabilities.
The obligation of Speedotron Corporation is limited to repair or replacement only and no one is
authorized to assume any obligation not in accordance with the above.
Do not attempt to make repairs to your Speedotron equipment. All electronic flash systems operate
on high voltage and high power. There is a high risk of severe electrical shock when opening a
power supply or light unit. Leave service to qualified and authorized electrical service personnel.
Authorized service personnel are familiar with the procedure to fully discharge a live unit (flashing
the unit is not enough to drain stored power even when the unit is unplugged). Repairs by unautho-
rized service personnel or by the user will void the Speedotron warranty.
Although we do have several service stations, we encourage you to send all repairs, under warranty
or otherwise, to our factory to ensure the best possible service. Not only will your unit be properly
repaired, but it will be given a routine updating of all circuitry that has been revised since your unit
was manufactured.
Should service be necessary under this warranty, return the item to us, prepaid (we do not accept
collect shipments). We, in turn, will expedite repairs and return the item to you, prepaid, via whatev-
er means of transportation you used to ship it to us (applies to continental U.S.A. only).
This warranty is not valid unless you fill out and return your warranty registration card. Equipment
should be registered within 10 days of purchase.
