4 Installation
The Cloud CX163 occupies one unit of standard 19” equipment rack. The microphone input and all zone
outputs are balanced. The CX163 is 150mm deep but a depth of 250mm should be allowed to clear
connectors and cables. Ventilation holes on the base of the unit should not be obscured.
5 Stereo/Music Inputs
The line inputs are suitable for most music
sources such as compact disc players, tape
players and receivers etc.. All inputs are
unbalanced and use RCA type phono
sockets. Input impedance is 48k
Ω. Each
zone on the CX163 can operate in either
mono or stereo mode; the default setting for
each zone is stereo. The mode of each
zone is determined by the position of their
internal jumpers.
J8: Zone 1
J7: Zone 2
Self-adhesive labels (supplied) can be
affixed to the front panel to identify the
available input sources.
