The Glensound GSGC5 is an outside broadcast mixer ideally suited to news gathering or sporting events. Using digital bandwidth compression techniques it provides 7.5kHz bandwidth circuits between the studio and the outside broadcast site using a single ISDN2 B channel. Absolute Broadcast's Glensound ISDN GSGC5 Commentary boxes come with  G722 and ATPX codecs.

Fully self contained, the GSGC5  is compact, flexible and easy to operate. Just plug into an ISDN2 S bus, dial the studio and be ready to broadcast. Facilities are provided for two commentators, an effects mic and a tape machine. An internal DTMF generator is used to generate ringing, dialling, engaged and other tones. This generator can also be used, after a call has been established, to signal the studio. A DTMF detector and sounder are also fitted so that the studio can signal the commentator.

Mic inputs, mixer and cue outputs are transformer coupled and provided on XLRs. The mixer output is even line drive capable and in the absence of an ISDN line the cue output automatically becomes a cue input, so the equipment can be used on analogue lines. Comprehensive software enables customers to configure the unit to suit their exact needs and up to 12 telephone numbers can be stored in non volatile RAM. Although normally battery operated a connector is fitted for an external DC supply.
