connector on
the controller until it locks into place (see
Figure 6).
• The removable connectors will only fit one way on the controller.
Zone Line Output Connections
In addition to Speaker Output connectors, each zone on the C4630 SE also has a set of
Line Output jacks (see
Figure 6). The Zone Line Outputs let you connect high-power
amplifiers to individual zones that require more power than the C4630 SE’s built-in
30 Watt/ch amplifier can provide, or expand a zone into sub-zones by using a multi-
channel amplifier.
Line Output Fixed/Variable Switch
Each zone Line Output has a push-button switch that toggles the Line Output between
V
ARIABLE
(OUT) and F
IXED
(IN). (See
Figure 6.) The V
ARIABLE
setting allows zone keypad
and remote controllers to control the level of the Line Outputs. In the F
IXED
setting the Line
Output level cannot be varied. Keypad and remote control M
UTE
controls function in
both
the F
IXED
and V
ARIABLE
settings.

NOTE: Setting a zone’s output to Fixed disables the following Sonance Control Manager Zone Setup
features for that zone: Default Volume, Maximum Volume, Page Volume, Balance, Bass, Treble. See
pages 29 and 30.
Connecting a High-Power Amplifier in a Zone
1. Set the zone’s Variable/Fixed Output switch to the V
ARIABLE
(OUT) position.
2. Connect a stereo RCA cable from the appropriate Zone Line Outputs on the C4630 SE to the high-power amplifier’s
input connectors (see
Figure 7, on page 14). The V
ARIABLE
setting allows the zone’s volume to be controlled by the C4630
SE via a keypad or a properly-programmed IR remote.
Using a Multi-Channel Amplifier for Sub-Zone Expansion
1. Set the zone’s Variable/Fixed Output switch to the F
IXED
(IN) position.
2. Connect a stereo RCA cable from the appropriate Zone Line Outputs on the C4630 SE to the multi-channel amplifier’s
Bus input connectors (see
Figure 8, on page 14). For example, an 8-channel amplifier like the Sonamp 875D SE will
let you put four speaker pairs in the zone. The F
IXED
output setting allows the C4630 SE’s Mute function to mute all
four sub-zones. Volume for each pair of speakers in each sub-zone is controlled by an in-wall volume control.
3. Connect the Control Out on the C4630 SE to the External Control input on the sub-zone amplifier (if available) to
automatically power-up the external amp when any zone on the C4630 SE is ON.
NOTE: The C4630 SE can also turn connected amplif iers ON and OFF via serial control. See page 40.
