Glensound 2 Channel 4 Wire subrack with IFB
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.
This has two 3-way talk switches. A rear-mounted XLR input provides a programme input. Speak on/off control is via sprung keys. Two switches allow the user to switch between program and interruptible foldback, I/P and 4wire. A third control allows control over mix and cut.. Controls next to each talk switch set the level of the incoming 4-wire signals heard in the speaker and headphone.
