Overview: The CAS44 is a multi-room control and
amplifier central unit. The CAS44 is compatible with the KPL remote
keypads with LCD display, the KP4 remote keypads, and the CAS-RC
learning and pre-programmed wireless remote.
Inputs: There are four analog stereo inputs (RCA) to
connect four source components; CD player, digital music server, iPod,
Speaker Outputs: The CAS44 powers four pair of
speakers in four different zones (locations). Each pair of speakers'
wires attach to a modular snap connector, which then plugs into the back
panel. The power output is 20 watts RMS per channel measured into 8Ω
from 20 Hz-20kHz with no more than 0.1% THD, the S/N is 90 dB, and the
minimum recommended speaker impedance is 8Ω.
Keypad Ports: Four remote keypads are wired to the
CAS44 using CAT5 cable. The rear panel ports use RJ-45 connectors. Like
the four speaker outputs, the four keypads correspond to four
independent zones. Both the KPL keypads and the KP4 keypads are
compatible with the CAS44.
RS-232: An RS-232 port allows control of the CAS44
by a computer, home automation system, or another device with an RS-232
interface. Firmware updates are also downloaded using this port.
IR Outputs: Two 3.5mm mini-jacks pass IR commands
from all the connected keypads to the source components via the two
included dual IR emitters.
Mute Input: When 12 volts DC is applied to this
3.5mm mini-jack the system will mute the speakers in all four zones;
this might connect to a doorbell or paging system.
Trigger Output: When any zone is turned on 12 volts
DC is output from this 3.5mm mini-jack; this can trigger an external amp
or source component to turn on. The output is turned off 5 minutes after
the last zone is turned off.
IR Emitters: Two dual IR emitters are included with
the CAS44, each having a 10' cable. One end of each cable has a single
3.5mm mini-jack that plugs into the rear panel of the CAS44. The other
end has two small IR emitters, designed to mount directly to the IR
receivers of your source components. The cable splits into two emitter
leads 3' from the end, and each emitter is attached to different
