Lighting #22 AWG, other wires minimum #24 AWG.
2. All shields should be grounded at audio panel only,
other end remains floating
3. Pins 8 and 9 connected through a 5 A breaker.

low when PTT active.
5. All shielded wires must be MIL 22750 or 27500.
6. Music inputs are independent. These can be internally configured,
so external wiring is not necessary to operate both from the SIRUIS module.

placing pilot microphone on speaker output when PTT active.
