I am trying to split the output of an audio channel output "mix" (there is no mixing panel between the mic inputs to amplifier and speaker). From what I can see, it appears that there is a line level out going to a wall plate/port with RCA female connectors. I essentially want to mimic that configuration (assuming its correct) but send it to a composite/rca splitter to then direct back to a PTZOptics streaming camera as its audio line input, rather than relying on the camera's built-in microphone.
Is this something that is possible to do? I am assuming I need a 2-conductor 18AWG cable, crimped to 2 Y-type terminal connectors one one end and 2 (red/white) RCA/composite male connectors on the other end.
What I am not sure how to do is connect it to the outputs of the amplifier. There is a 4/8 ohm, COM, 70V, and 100V screw-type terminals (see picture). I ASSUME it is COM & 70V as show in the image below, but I am not confident of the labeling on the wires. Is it possible to get the output to LINE level without shorting out or frying the splitter or camera or both?
EDIT: @Data Processing answered the question. You CANNOT run 70V out to composite splitter. I did omit a critical piece of information, however; there is a Nexia CS bi-amp whose output is going as input to the ASHLY amp. Based on @Data Processing's input, I assume I need to take the + & - bare wires on each composite connector and insert them in an available output on the bi-amp out to the splitter and finally the camera.
