Inputs
The main input is switchable between mic, mic+12v phantom power, and line. The input has an adjustable gain control to meet a wide range of dynamic, condenser, and ribbon microphones. The input passes through a broadcast quality compressor/limiter circuit designed to manage the peaks of excited commentary.

Outputs/Talkback
There are two output circuits. One is used as the main programme audio, the other as a talkback circuit. There are separate button controls for each of these using Config+. They can each be independently configured for latching or momentary, with the programme button also having a 'cough' feature. Both outputs are transformer balanced.

Monitoring
There are two monitoring inputs each with independent level control. Each of these inputs can be switched from the left ear, right ear, or both ears. There is a 4 LED level meter from -6 to +6 dB.

Power
Battery power is from 1 x 9v PP3, or an external DC power supply.The GS-CU004 is often used as a remote link to the main commentary unit. It is favoured by pitch side interviewers, and is popular in combination with wireless systems.
