Despite its wide range of features, the Telex MS-4002 is simplicity itself to use. Just plug it in (any AC power supply from 100V to 240V will do), insert a microphone or headset, connect intercoms to the rear panel and flawless communication is guaranteed.
Other features of the Telex MS-4002 Master Station are: voice-activated microphone (VOX), PA output, backlit keys, incoming call indicators, mic kill key and auto-sensing (dynamic/electret) headset connector.
