as follows:
user-selectable channels (0-9 and A-F).
The receiver must be set to the same
channel as its transmitter.
4. MixMode (MIX): The receiver receives
the monitor mix in either MixMode (MIX
ON) or stereo (MIX OFF). See MixMode/
Stereo Control on page 5.
HIGH: 4-8 hours of operation.
MEDIUM: 1-4 hours of operation.
NOTE: If the receiver is receiving
only one signal, it will be in mono.
LOW: less than 1 hours of operation.
5. High Frequency Equalization (EQ):
Adds 6 dB at 10 kHz for increased treble
response.
6. Limiter (LIM): The limiter provides pro-
tection against loud signal.
NOTE: If no bars are present
within the battery life gauge,
change the battery immediately.
Battery life depends on many
WARNING! Turning the Limiter OFF defeats protection against

MIXMODE/STEREO
The P4R receiver receives two signals (1/L and 2/R) from the P4T transmitter. The P4R processes
these signals in either stereo or MixMode:

STEREO: In stereo, the signals remain separate so 1/L is heard through the left earphone and
2/R is heard through the right earphone. The balance knob on the receiver adjusts the balance
between the left and right earphones.
MIXMODE: In MixMode, the signals are “mixed” in relation to one another using the balance knob,
blending into one signal. The mixed signal is sent to both the left and right earphones.

Step One: The P4R re-

sends the mixed signal to
both earphones.

MIXMODE IN APPLICATIONS
MixMode is most useful when two distinct mixes are provided to the P4T transmitter, such as a
band mix and a vocal mix. MixMode combines these two signals into one monitor mix and allows
you to control this mix during the performance with the P4R receiver. For example, if the band over-
powers the vocals in the mix, increase the level of the vocals and decrease the level of the band
by simply adjusting the balance knob.
