MUTE
Channels can be muted individually by shorting this terminal to ground. It provides approximately 45dB of attenuation.

STATUS OUTPUT
The status output is a DC logic output that is high (+5 Volts) when the channel is active and low (0Volts) when the channel is not active. This DC voltage can be used to key video cameras or trigger key lights on active microphones.
NOTE: Each channel can source a maximum of 10 mA.
18.MAIN OUT
The main output is a 600½, transformer balanced output that can be used to feed an external power amplifier. It is at this point the automatically mixed or the manually mixed output is accessed. The nominal output is 2.21 dBu (1 volt).
19.AUX OUT
The aux output is a 600½, transformer balanced output that can be used as an additional
20.REMOTE VOLUME
The master level of the mixer can be controlled remotely with a simple connection on the back of the unit. A 10k pot will provide approximately 0 to 25dB of attenuation. A 100k pot will provide 0 to 45dB of attenuation. If desired, a control voltage can be inserted to command 0
to 70dB of attenuation. The internal gain trim must be set full clockwise to achieve the maximum attenuation range of the remote volume (refer to diagram below).
NOTE: THE CONTROL VOLTAGE SHOULD NEVER EXCEED 13 VOLTS DC.
