Call Signaling
The MRT-327 can send and receive 20 kHz call signals.

Dual-Action Momentary/Latching Mic Switch
The Mic on/off switch can be used as a momentary push-to-talk switch or as a latching on/off switch.

Remote Deactivation
The MRT-327 can receive 24 kHz "talk-off" signals for deactivation of the MRT-327 microphone from a remote location.

Microphone Limiter
The microphone pre-amplifier circuit contains a limiter which helps to equalize output for different voice levels.

Optional Microphone Speaker & Headset Configurations
The standard MRT-327 accepts an unbalanced, dynamic-mic headset or a dynamic microphone used in conjunction with an external speaker located on the rear panel. It also has a jack for an optional Model MCP-90-xx gooseneck panel microphone. Additionally, the MRT-327 may be internally modified for use with a carbon or balanced-dynamic microphone. It can also be modified to provide the microphone audio as an unswitched, balanced output.

Powering Options
The MRT-327 receives operating power from the intercom line. It may be internally modified for local powering from a separate dc power supply or batteries.
