4 Installation
The Cloud CX462 occupies one unit of standard 19” equipment rack. Front panel pre-set controls can
be covered with the cover provided. Ventilation holes on the base of the unit should not be obscured.
The CX462 is 152.5mm deep but a depth of 200mm should be allowed to clear connectors.
5 Stereo/Music Inputs
The music section of the CX462 has six stereo inputs. These 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 connectors. 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 -17.6dBu (100mV) to
+ 5.7dBu (1.5V). The pre-set gain controls should be set so that all the input signals operate
at the same level within the CX462 and the music level controls have an optimum control range.
