The AV-RMIC consists of:
AV-MIC-REM: Lockable enclosure (with removable inner and outer doors) and microphone.
AV-RM-PCB: Remote microphone module, located in the AV-RMIC, which interfaces to AV-RMI and AV-
AMP-80 amplifier (see figure 17). The AV-RM-PCB supervises the AV-RMIC microphone for
open circuit, short circuit and disconnection conditions. The audio output of the AV-RM-PCB is
supervised for open and short circuit conditions and is isolated via an onboard audio
transformer.
AV-RMI:
Remote microphone interface module which interfaces to the AV-RM-PCB. It mounts in a single
AV-VBM or AV-VB enclosure and connects to a single AV-AMP-80 amplifier (see figure 16 and
17).
