COMMS AND RETURNS
Monitoring COM RTN
The COM RTN allows the Sound Mixer to hear communication back from oth -
er members of the production crew, such as the boom operator. The COM RTN
signal can be quickly heard in headphones by using the assigned A B/C toggle
action or by assigning it to a custom HP preset. For two-way communication,
activate private comms (COM Send) and COM RTN at the same time.
The following procedure describes default behavior of the A B/C switch;
however, it may be modified to behave differently. See Setting MIC/TONE and
A B/C Switches for more information.
To monitor COM RTN:
1. A: Press and hold the SELECT encoder while sliding the A B/C
switch left. The headphone monitor source changes to COM RTN.
2. When finished, slide the A B/C switch right to return to the selected monitor
source.
