The GS-FW008 is an economical highly versatile belt-pack box designed for use in outside broadcast environments.

It is powered from 1 x PP3 battery (greater than 10 hours life) and also has an external DC input.

A toggle switch turns the unit on/off and a bright blue LED indicates that the unit is on and flashes when the battery is getting low.

The unit has 1 input switchable between: MIC / LINE / MIC + 12v PHANTOM This input has a gain control for setting the level.

The input is sent via a toggle switch (both latching & momentary) to both a zero dB transformer balanced XLR output and the right channel of stereo output.

There are a further 2 inputs marked 4W and STEREO.

Both of these inputs are mixed together and sent to a headphone amplifier providing the user with monitoring of the incoming audio.

The 4W input (balanced zero level) can be sent to the 4W output if the Interruptible Feed Back (IFB) switch is made.

The stereo input is always fed to the stereo output. The stereo circuit is suitable for use from the output of headphone amplifiers as well as other stereo feeds.
