Glensound CO-AXIAL commentators equipment is an industry standard for international events with a large number of commentators. We have now developed equipment for use with fewer commentators but where sound quality is of particular importance. The system consists of 1, 2 or 3 commentators boxes type GSGC2 along with a base station. There is a choice of base station. The first and simplest is a GSGC3 which is basically a power unit and break out box to handle up to 3 GSGC2s. A more comprehensive base station is our GSGC11 whose facilities include mixing and monitoring circuits.

Consumption < 20VA

The GSGC3 uses a mains transformer with two primary windings connected in series. It is
possible, by the use of tools and a soldering iron to reconnect these primary windings in
parallel. Then the input voltage would be 115volts +/- 10%
