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
Splitter allows multiple keypads in each zone.
For ease of installation and simplicity of use, the
CAS44 controller does not require any program-
ming. All source commands reside in the included
CAS-RC programmable remote control.
The CAS44 system passes IR commands from the
remote 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 trig-
ger output, as well as an RS-232 port with a docu-
mented serial protocol. This port can also be used
to update the system firmware.
The CAS44 system keypads connect to the con-
troller 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.
