Do Not connect 120vac directly to any pin on this connector. Severe damage
to the console will result and possible electric shock hazard. Switching of
large AC voltages should only be done thru external relays capable of
handling the voltage and current.
5.0 Telephone Inputs and Mix Minus
Blue 5c offers a mono telephone Send bus, in addition to the Program and Cue outputs. This unit interfaces
with commercial phone hybrid systems and provides a “Mix Minus Return” to the telephone hybrid.
You may insert the Line audio from the hybrid into any of the 10 inputs.
The audio you wish sent back to the hybrid (return), should have the “SEND” button depressed above the
mixer position. This will send a Mono feed from the Program bus back to the hybrid.
