The CM-300L Console Mount User Station w/ an A4F Headset Connector from Telex is a two-channel select console mount user station. The user station is designed to be used in a full duplex, conference line intercom system.
It features a microphone limiter circuit, separate dynamic and carbon microphone inputs and silent channel-select switching. In normal system operation, one or more users talk and the others listen. A microphone switch on each station allows the talker's microphone to be enabled and allows the listeners to keep their microphones disabled.
The unit is housed in a solid metal front cabinet and the back is open for console mounting. The CM-300L uses the MCP-3 mounting kit.
