GS-GC2
Comentators' Box For Multiwire Commentators System

Features Description Specifications Accessories Downloads Ask a Question
  • Separate 5 channel mixer provided for each ear
  • TB switches cut programme output
  • Massive Headroom
  • Connected to base station with a single multi-pair cable
  • Facilities for 1 commentator

Glensound CO-AXIAL commentators equipment is an industry standard for international events with a large number of commentators. This multi wire equipment was developed 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. Interconnection between base station and boxes is using 25 way multiwire cables terminated in 25 way plugs & sockets.

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%

ACCESSORIES INCLUDED 
One x 3M long multiway D lead is supplied with each GSGC2 
For UK sales only - One IEC mains lead is supplied with each GSGC3 
Other mating connectors are not included. 

ACCESSORIES AVAILABLE 
Glensound can supply polycarbonate or aluminium cases to house various 
combinations of units with or without the cables. 

Interconnecting D leads can be supplied up to 50M long. 

Suitable closed or open ear broadcast quality headsets. 

The GSGC2 front panel is punched for a multipin XLR connector for a 
headset. Because there are no fixed standards for the number of pins or the 
pin outs of headset connectors, this connector is not normally fitted. It is possible 
for us to fit any XLR connector as an extra, wired to your specification.
