General Description
The Cloud CX462 is a versatile, rack-mounting (1U) stereo audio
mixer designed for installed sound applications where multiple
microphone and music sources are in use. It is particularly suitable
for use in AV presentation situations such as training rooms and
lecture theatres, houses of worship, where multiple microphones are
often employed, and other retail and leisure venues where a exible
audio system for music and announcements is needed. A tamper-
proof cover may be tted to the front panel which covers the
controls related to system set-up, but leaves the main level controls
accessible.
The CX462 has six stereo line inputs and four mono microphone
inputs. Internally, the mixer is divided into two separate sections,
one for music, the other for microphones. In the music section, front
panel controls select one of the six stereo line inputs and set its
level. The music section has its own balanced output, which may be
congured as mono or stereo. In the microphone section, the four
mic inputs are mixed together, with front panel rotary controls for
adjusting both individual mic levels and the level of the summed mix.
The microphone section also has its own balanced output, in this
case, in mono. The CX462 circuitry includes two “blend” signal paths,
whereby the music signal may be added to the summed microphone
output at a user-variable level, and conversely, the mic sum signal may
be added to the music output with its own user-variable level control.
These two paths are independent and may be used simultaneously.
Standard Cloud remote control plates may be used with the CX462
to control the music level only, the music level and source selection,
or the microphone mix level. The CX462 may also be tted with
an optional RS-232 serial control interface; this allows full remote
control of music source and level, master microphone level and both
mic and music muting.
The CX462 is directly compatible with Cloud PM Series paging
microphones. Alternatively, Mic 1 input may be congured to
suit most OEM paging systems: paging may be activated by voice
(VOX) or short-to-ground access connections, and Mic 1 may be
congured to have priority over the other three mic inputs to
prevent announcement clashes. Additionally, one line input may be
set to have priority over any other selected to facilitate connection
of a digital sound store or similar device.
Bose® EQ cards may be tted to any or all of the three outputs.
