GSBC2 Commentators Box

General
Most commentary systems manufactured by Glensound consist of two parts, an engineering position (base station) and a commentary position (commentator’s box). This GSBC2 unit is a stand alone commentators box that requires no base station to operate. All inputs and outputs to this unit are balanced audio circuits and would normally interface directly to an outside broadcast vehicle. It is however, entirely practical to interface directly which audio lines.

Two main programme outputs. Second output can be cut.

The GSBC2 was originally designed for horseracing commentary and some of it's features are fairly specialised. We now offer one modification that has been requested by a number of different customers as a standard variation called the GSBC2A.

The GSBC2A has different routing of the 2nd commentators mic & different operation of the 2nd output.

The 2nd output is now always derived from only the 2nd commentators mic and the 'cut 2nd output' switch is changed to become a mix the 2 commentators mics together onto output 1.
