  • 1Description
The CM-300L Console Mount User Station w/ an A5F 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.

Volume Control
The volume control on the CM-300L has a wide range to compensate for: user hearing differences, ambient noise variation, variations in headset / handset sensitivity, and variations in voice. The volume control in the CM-300L reduces distortion by driving the headphone amplifier only as much as needed
Microphone Switch
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. In this condition, speech intelligibility is enhanced since background noise from other microphones is not present. On the Model CM-300L, a toggle switch turns the microphone on
Channel Select Switch
A channel selector switch allows a choice of two (optionally three) channels. When the switch is on the "1" position the station talks and listens on channel 1, on the "2" position, to channel 2
Call Light Push Button
Pushing this button transmits a call signal to all other units on the channel selected by the channel selector switch. A call signal on this channel will cause the call light push button to flash. The flash rate is 2 to 5 times a second. The call signal itself is a 20kHz signal
