3. Mix Mode/Stereo Control
The receiver receives two signals (1/L and 2/R) from transmitter, then processes
these signals in either mix mode or stereo:
Stereo: In stereo, the signals remian separate so that 1/L is heard throughthe
left headphone and 2/R is heard through the right headphone. The balance knob
on receiver to adjusts the balance between the left and right headphones.
Mix Mode: In mixmode, the signals are mixed in relation to one another using
the balanced into one signal. The one mixed signal is sent to both the left and
right headphone.
Stereo Control

Mono Control
Used for conventional stereo monitor mixes
Used for mixing and combining an individual mix between
