Glensound 4 Wire Talkback & Talkback Into Headphone Circuit
Description
GLENSOUND BROADCAST INTERCOMS - 4 wire and IFB
Intercoms using 4-wire topography are often used in broadcast environments, particularly in outside broadcasting, where the simplicity of the wiring simplifies the connection of an ad-hoc or semi-permanent system to communicate between personnel and, with IFB, provide cue to operators and presenters. The models in this selection are all designed to inter operate with equipment using standard broadcast operating levels and connectors. They range from a single-circuit belt-pack for use with headphones to six circuit, rack-mounting intercoms, with integrated loudspeaker and talkback microphone.
GS-FW008 - 1x 4W circuit - IFB, 1x stereo cue in
This has a microphone input, with 12V phantom power, which may be switched to suit a line level signal, a 3-way talk switch and a headphone socket. A stereo programme input, 6.35mm jack socket, 47k ohms, may be switched to feed the 4-wire output interrupted by the talk switch or to a stereo auxiliary output again a 6.35mm jack. Power: 1x PP3 or external 12-20V DC.
