The Cloud CX263 occupies one unit of standard 19” equipment rack. The microphone inputs and all zone
outputs are balanced. Ventilation holes on the base of the unit should not be obscured. The CX263 is
150mm deep but a depth of 250mm should be allowed to clear connectors.
5 Stereo 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.
5.1 Sensitivity and Gain Control
All six line inputs have pre-set gain controls which are accessible on the rear panel, adjacent
to their respective input sockets. The input sensitivity can be varied from -18dBu (100mVrms)
to + 6dBu (1.5Vrms). The pre-set gain controls should be set so that all the input signals
operate at the same level (0dBu) within the CX263, which ensures that the music level controls
have an optimum control range.
