RTS WM300L/A4F WM-300L A4F

RTS' WM-300L Wall mount User Station works within the TW Intercom System as a private listening headset station. It is designed to fit directly into a standard 4" square (2-gang) electrical conduit box 2-1/4" deep. The rear section is not enclosed and uses the back-box to provide a housing when installed. The user station is perfect for permanent installations where a wall-mounted station can provide an unobtrusive operating position. Most often it is located where the operator can conveniently attend to on-going operations while wearing a headset. A handset can be used in place of a headset if desired. Practical operating features include two-channel selection, a latching-action microphone on-off switch, a momentary-action microphone on-off switch, and a headphone volume control. User-oriented features include a microphone limiter circuit for equalizing levels, a powerful headphone amplifier, silent channel- select switching, and well-placed controls for ease of operation. Most any type of headset may be used with the WM-300L; low-Z or high-Z headphones, with dynamic or carbon microphone. The carbon microphone headset port also accepts "Plantronics" telephone-type headsets. Screw terminals mounted on the circuit board are provided for user station interconnection to the line. A two-pair shield cable such as Belden 8723 or equivalent is recommended since it allows each channel to be carried over a separate shielded pair, reducing the possibility of crosstalk between channels.
