Description
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 2 output circuits. 1 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 2 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.
