A large four wire base station for 12 circuits. Each circuit has its own talk button, return level control, and incoming audio present LED so that you can identify the incoming audio source. There is also a programme input with level control for the GS-FW028 speaker or headphones.

There is a gooseneck microphone with an adjustable level loudspeaker. A 3 pin XLR & 6.35mm jack is on the front panel for connecting a headset.

Connections are on rear panel D-types. Each circuit has two inputs - one that goes to the GS-FW028 monitoring system, the other is fed back down the four wire circuit and is interrupted when the GS-FW028 talk key is pressed.

The GS-FW028 was previously known as the GS-TC9
