Glensound 4 Channel Four Wire Box
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-FW027 - 4x 4W circuits - Vox
This is an upright, desk mounting design. It has four PTT switches, a 5-pin female XLR provides a headset socket, there is no loudspeaker. 12V phantom power is available for the microphone. There is a volume control for the earpieces. Four controls set the level of the 4-wire incoming signals heard in the headset; each signal can be set to feed left, right or both ears. Each PPT switch has a VOX circuit: when an associated switch is selected, the signal from the headset microphone is sent to the 4-wire output when it reaches a threshold set by a rotary trimmer. 4-wire connections are on the rear; each 4-wire circuit is connected by means of a 5-pin female XLR socket. Power: External supply, 10-30V DC.
