CX163 Installation and User Guide v1.1
6
OVERVIEW
Introduction
The Cloud CX163 is a 1U rack-mounting audio mixer
suitable for use in leisure sector venues - such as licensed
premises - where easy control of stereo background music in
two separate areas needs to be combined with a microphone
or paging system.
The CX163 independently mixes any one of six stereo line
inputs with a microphone input for each stereo zone output.
Separate controls for music and mic levels in each zone
are provided, and music level may be controlled remotely if
wished, either using standard Cloud remote control plates,
or from an AV control system (e.g., Crestron, AMX, etc.) The
zones may be configured for mono operation if wished.
In addition to the two primary zone outputs there is also
a Utility Output, suitable for secondary areas such as
corridors and toilets. The music source for the Utility Output
is determined by internal jumper settings; the mic input is
mixed with the music signal in a similar manner to the other
zone outputs. There are no front panel controls for the Utility
Output.
The mixer may be configured to operate with most paging
systems: the mic input may be activated by voice (VOX)
or short-to-ground access connections. Additionally, in
Zone 1, Line Input 6 may be set to have priority over any
other selected to facilitate connection of a juke box, digital
sound store or similar device.
A Music Mute input is provided to allow external systems
such as fire alarm panels to disable background music in the
event of an emergency. This is a function that may be required
by Local Authority regulations.
Optional plug-in EQ cards may be fitted to any or all zone
outputs to optimise the CX163 for use with various installed-
audio loudspeakers.
What’s in the box
Unpack the CX163 and its accessories with care. It is always a
good idea to store all packaging (if practical), in case you ever
need to return the unit to your Cloud dealer for any reason.
