Channels can be muted individually by shorting this terminal to ground. It provides
approximately 45dB of attenuation.
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.
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).
The aux output is a 600½, transformer balanced output that can be used as an additional
non-automixed output. The nominal output is 2.21 dBu (1 volt).
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.
