The Cloud CX163 is a two-zone, rack-mounting (1U) audio mixer
suitable for use in licensed premises or other leisure sector venues,
shops, offices, hotels, or any space where easy control of background
music in two separate areas needs to be combined with a microphone
or paging system.
speakers in general areas such as foyers and toilets. Music level
may be controlled remotely in each zone by standard Cloud RL-1
remote control panels if wished, and if zone outputs are configured
as mono, separate RL-1s may be connected to control the left and
right outputs.
The CX163 has six stereo line inputs and a microphone input. It has
two separate zone outputs, in each of which one of the line inputs
and the microphone input may be mixed together. Separate control
of music source selection, and music and mic levels are provided
for each zone. The two main zone outputs are stereo, and there is
an additional fixed-level mono utility output, which is suitable for
The CX163 is directly compatible with Cloud PM Series paging
microphones. Alternatively, the mic input may be configured to suit
most OEM paging systems: the mic input may be routed to either
zone by short-to-ground access connections. Also, in Zone 1,
LINE 6 input may be set to have priority over any other selected
input to facilitate connection of a digital sound store or similar device.

CONTROL PANEL
The example shows a CX163 used to provide music and paging in
two separate areas (zones) of a pub or bar. Each area can set its own
volume by means of the local RL-1 remote control panels (optional).
Alternatively, it can be set from the front panel of the mixer itself.
Music at a lower level could be made available to a third area, such as
the lobby or toilets.
Paging to either or both zones is achieved using a paging mic (such as the
Cloud PM4), which would typically be located somewhere other than
either of the two zones.
Note that the jukebox is shown connected to Line input 6; If Line 6
Priority is enabled in the mixer, then whenever the jukebox is in use it
will always be heard in Zone 1, regardless of the music source setting.

Architect’s and Engineer’s Specification
The mixer shall be equipped with six unbalanced stereo music inputs
on rear panel phono sockets (RCA jacks), one electronically balanced
microphone input, two main zone (L & R) electronically balanced
outputs and one electronically balanced mono utility output, all on
rear panel multipin connectors.
The mixer shall have two stereo channels designated Zone 1 and
Zone 2. Except where indicated below, the channels shall be identical.
The microphone input shall be mixed and summed with the music
input selected in each channel separately. Each channel shall have
its own front panel microphone level control. The music input to
each channel shall be selected by 6-position front panel rotary
switches. It shall be possible to control the level of the music source
independently of the microphone levels in each channel.
Each music input and the microphone input shall also have a rear
panel input sensitivity control. Independent two-band equalisation
adjustment shall be provided on the rear panel for i) the music
signal in each mixer channel and ii) the microphone input. Phantom
power shall be available at the microphone input when selected by
an internal jumper.
A control input shall be provided to activate the microphone input
by external contact closure, with separate routing to each mixer
channel. It shall be possible to configure the mixer such that this
function is overridden and the microphone input is always active.
It shall also be possible to configure the mixer to perform the
following functions: i) detection of a signal on the microphone input
will automatically reduce the music level by 30 dB; ii) one line input
will automatically override any other in one mixer channel only when
a signal is present at the input, even if it is unselected.
The mono utility output shall be configurable internally to
i) follow whichever music source is selected to either mixer channel,
or ii) to be permanently fed with a mono sum of one line input; this
line input will not be the same one that can be set to have priority
over the other line inputs. If the utility output is selected to follow
the music signal in mixer channel 1 and the priority line input feature
is enabled, the priority line input will also feed the utility output when
the input becomes active. The microphone input shall also be mixed
into the utility output and it shall be possible to set the microphone
level at the utility output independently of that at the main outputs
with a rear panel control.
The mixer shall accept a range of plug-in equaliser cards to permit
use with compatible loudspeakers. It shall be possible to fit these in
any or all of the outputs.
The mixer shall be built in a 1U steel chassis for mounting in a
standard 19” rack. A front-panel LED shall indicate when mains
power is applied to the unit.The mixer shall operate on mains supply
voltages from 85 to 253 V. Mains supply shall be connected via a
detachable IEC cable.
The mixer shall be the Cloud CX163; the optional remote control
panel shall be the Cloud RL-1 Series.
Optional remote control panels shall be available to permit control
of music level in either mixer channel; it shall be possible to retrofit
these to the mixer at any time. The remote control panels shall
connect via a rear panel multipin connector. It shall be possible to
disable the front panel music level controls by moving an internal
jumper.An external control input shall be provided to allow muting of
the music source by a fire alarm or other external emergency system
via isolated, ‘volt-free’ contacts, and this input shall be configurable to
respond to either a short or open external circuit.
