Applicable Models
This manual describes the installation and operation of the
following models:
Cloud CXV-225 2-channel amplier – •
2 x 250 W, 2U 19” rack unit
Cloud CXV-425 4-channel amplier – •
4 x 250 W, 3U 19” rack unit
Apart from the number of channels and the units’ physical
dimensions and power consumption gures, the two
models are otherwise identical for the practical purposes of
installation and operation.
General Description
The Cloud CXV-225 and CXV-425 are high power
(250 W/ch), multi-channel audio ampliers intended for use
with high quality PA and background music systems in ofces,
hotels, factories, leisure facilities and other commercial and
industrial premises.
They are designed to drive 100 V line speaker systems
directly, and have no low-impedance outputs. Low impedance
loudspeakers can only be connected to these ampliers
with the use of an intermediate 100 V line transformer.
Loudspeakers designed for such ‘installed-sound’ applications
will normally include an integral transformer, typically with
selectable output power taps. If you have any doubt about
the suitability of this amplier for the speaker system it is to
be connected to, please verify that the speakers are of the
100 V line type with the manufacturer.
Unlike traditional 100 V line amplier designs, the CXV-225
and CXV-425 do not employ an output transformer. This
produces a considerable saving in weight and a signicant
improvement in audio quality.
