1 DESCRIPTION
The GXT 4000 microphone console is a touch screen console. It has from 16 up to 64 programmable soft
keys for making PA broadcasts into selected areas or zones. It is designed to operate over a bus architecture,
meaning that several consoles can be used over the same network, while collectively occupying just one single
audio channel. In fact, the consoles are self-regulating, with audio channel priority always being given to the first
console that picks up the channel. The main part of the console may be flush fitted or mounted on its own swivel
base for tabletop use.

•
an electret microphone,
•
a touch screen for setting and selecting zones,
•
a memory card reader for broadcasting pre-recorded messages,
•
