Russound CAS44 User manual

Data Sheet: CAS44
Multiroom Audio Controller-Amplifier
The Russound CAS44 Multiroom Audio Controller-
Amplifier distributes four stereo sources to four zones.
Two controllers can be linked together to support a
total of eight zones.
Each zone has its own built-in stereo amplifier that
provides 20 watts RMS per channel. The system also
provides independent control of bass, treble, balance,
loudness and volume from the keypad in each zone.
For zone control, the CAS44 system offers a choice of
two keypads. Using the optional SA-ZX3 Keypad Split-
ter allows multiple keypads in each zone.
For ease of installation and simplicity of use, the
CAS44 controller does not require any programming.
All source commands reside in the programmable
CAS-RC System Remote Control.
The CAS44 system passes IR commands from the re-
mote control through the keypads to the sources. Two
common IR output ports allow connection of infrared
emitters or an IR connecting block for device control.
To provide easy integration with paging systems, home
automation systems and other devices, the CAS44 has
a muting trigger input and system trigger output, as
well as an RS-232 port with a documented serial pro-
tocol. This port can also be used to update the system
firmware.
The CAS44 system keypads connect to the controller
with CAT-5 or CAT-5e cable. The speakers connect to
the built-in amplifiers with standard speaker cable.
Rack ears are included with the CAS44 controller for
2U rack mounting.
