2 General Description

The Cloud CX163 is a stereo mixer zoner with two stereo zone outputs and a mono, fixed level utility
output. It has applications where up to six line level music signals and one microphone are required to
feed two separate zones (both stereo) and a utility zone (such as toilet areas etc.). The CX163 provides
microphone priorities, fire alarm music mute, paging microphone facilities and the possibility for Line 6 to
take priority over other music signals in Zone 1.

Front panel controls have been kept to a minimum. Most behavioural controls can be found close to their
respective inputs on the rear panel.

There are various optional accessories that extend the flexibility of the CX163:

w

Optional remote plates which control music level on the two stereo zones.

w

A dedicated four zone paging mic with pre-announcement chime.

w

Equalisation Modules for Bose® Speakers.
