GSOC33 COAXIAL COMMENTATORS CONTROL UNIT
GSOC34 COAXIAL COMMENTATORS BOX

GENERAL
Glensound have been manufacturing co-axial commentator’s equipment for many years. This equipment is based on our previous ranges of co-axial commentator’s units. These were our very original GSOC3 & 4 units followed by our GSOC23 & 24 units.

COMMENTATOR’S BOXES GSOC34
These provide facilities for up to three commentators. Each commentator has 6 audio sources that can be mixed and selected to either or both ears to suit his own requirements. In addition he is forced to listen to a hidden TB level. Each commentator can speak to the main programme output, a co-ordination output circuit or to the technician. Headset connectors are XLR3 pin fixed sockets for the microphones and Tip, ring sleeve jack sockets for the headphones.

COMPATIBILITY
This equipment is not compatible with our previous units. No damage will occur if old and new units are mixed but the equipment will not operate correctly.

SYSTEM
A system always consists of a base station and a number of commentator’s boxes. The GSOC33 base station is usually fitted with 10 channels to operate with 10 commentator’s boxes. It is possible for Glensound to supply the base station with any number of channels up to a maximum of 10. Each commentator’s box is connected to the base station with a single 75 ohm co-axial cable. See WP77-29 for the specification of suitable cables. The maximum length of cable is 500metres.

TRANSMISSION
Time division multiplex is used to pass 3 audio signals from the commentator’s box to the base station as well as 7 audio signals from the base station to the commentator’s box. Simultaneously data is passed in both directions down the co-axial cable and power is passed from the base station to the commentary box.
