Intercom for conversation through a glass partition comprising a desktop speaker unit with gooseneck microphone and an extension speakerphone unit, which can be positioned horizontally or vertically in the client area. Independent level controls for the main unit and client speakerphone provide tailored adjustment to overcome the ambient noise level, with muting and anti-feedback circuitry to make two-way conversation clear and intelligible. An additional output is provided for recording both sides of the conversation. Applications include ticket booths, bank counters, petrol stations and receptions.Dimensions : main unit[tab]158 x 87 x 46mm[br]Weight : main unit[tab]347g (inc. microphone)[br]Dimensions : client speakerphone[tab]91 x 77 x 23mm[br]Weight : client speakerphone[tab]87g (inc. lead)[br]Lead length[tab]1.6m (hard-wired to speakerphone)[br]Dimensions : microphone[tab]285 x 113mmØ (fixed to main unit)[br]Connectors[tab]3.5mm TRS speakerphone, 3.5mm stereo record out[br]Controls[tab]2 x volume control & power on/off[br]Power supply[tab]9Vdc 300mA min.
