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

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.
