Mute
Pull two conductor stranded wire from the 12VDC output on the device that will trigger audio muting to the
C-4.4 Controller location. Terminate with a 3.5mm mini plug at the C-4.4 end.
POLARITY:
TIP = +12VDC,
SLEEVE = GND.
WIRE GAUGE:
20AWG up to 500’; 18AWG up to 1000’. Non-shielded preferred.
MAX
VOLTAGE IN:
32VDC.
NOTE:
Audio mute function will mute all active zones when 12VDC is present on this input. No additional
programming or configuration is required.
RS-232
When used for a control buss between C-4.4 Controllers in an expanded system using two Controllers,
use a pre-configured 3.5mm stereo mini to mini plug cable. When controlling the C-4.4 from an external
controller such as a whole-house control system or touch panel, use a cable with at least three
conductors and terminate control system or touch screen end as appropriate. Terminate the C-4.4 end
with a three-circuit (stereo) mini plug using the following pin-out:
NOTE:
RS-232 Connections should not exceed 50’.

Trigger
Pull two conductor stranded wire to a voltage sensing device to be controlled by the C-4.4. Terminate the
C-4.4 end with a 3.5mm mini plug. Terminate controlled device end as appropriate.
POLARITY:
TIP =
+12VDC, SLEEVE = GND.
WIRE GAUGE:
20AWG up to 500’; 18AWG up to 1000’. Non-shielded
preferred.
NOTE:
Check polarity on Trigger connections before powering up the system. An Improper connection
can cause damage to the controlled device, the C-4.4 or both.
CONNECTIONS
When connecting source components, or making any connections, be sure that the C-4.4 Controller and
all system devices are turned OFF and disconnected from AC power to prevent electrical shock and to
avoid possibly damaging components.
HEAD END CONNECTIONS
Keypads
Using CAT5 cable properly terminated with a RJ45 plug (see section:
Wiring/Keypads
) connect the zone
CAT-5 cable to the appropriate zone ‘To Keypad’ terminal on the C-4.4 rear panel.
Speakers
1. Using 14-16AWG two-conductor stranded wire, strip approximately ¼” of insulation from each
conductor. Twist the strands until tight.
2. Connect the bare wires to the appropriate L+,L-,R-,R+ terminals on one of the included four-position
plug-in connectors. Be sure to maintain proper polarity. Be sure there are no loose strands sticking
out that could cause a short.
3. Plug the connector into the appropriate zone speaker terminal.
