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-FW004 - 1x 4-wire circuit - Passive, free-standing

This has a single 4-wire connection which must be connected to equipment with low source impedance, 50 ohms or less, and high input impedance, 10k ohms or greater. It provides a 2-wire output, presented on both male and female 3-pole XLR connectors, wired in parallel. The 2-wire connection must be terminated in 600 ohms.
