SONAMP® 875D SE 8-CHANNEL AMPLIFIER

Source Connections (see Figures 6 & 7)

Always use quality high-fidelity interconnect cables such as Sonance MediaLinQ® Bronze Interconnects. If source components are more than 20 feet from the amplifier, use the Sonance LS2 and LR2 Balanced Line-Level Sender and Receiver (sold separately) to avoid signal degradation.

NOTE: Always check local building codes before installing wire in walls or ceilings.

•Connect stereo source components (receiver, preamp, page signal, etc.) that will feed all 8 channels to the BUS LEFT & RIGHT inputs (see Figure 6).

•Connect a mono auxiliary source (page signal, electronic doorbell, etc.) that will feed all 8 channels to the BUS AUX input (see Figure 6).

•Connect zone-specific sources (audio control system zone output, video game, etc.) into the individual channel DIRECT inputs (see Figure 7).

•Connect additional amplifiers to the buffered Bus Outputs (see Figure 6). The source connect- ed to the BUS LEFT & RIGHT Inputs appears at the L and R OUTPUTS, and the source connected to the BUS AUX input appears at the AUX OUTPUT.

Input Assignment DIP Switches (see Figure 8)

The Sonamp 875D SE’s Input Assignment DIP switches provide the most flexible configuration options of any multichannel amplifier. Settings are changed by setting the switches either OFF (left) or ON (right):

DIRECT: Assign channel to the channel DIRECT input source.

LEFT: Assign channel to the Bus LEFT input source (default for odd-numbered channels)

RIGHT: Assign channel to the Bus RIGHT input source (default for even-numbered channels)

AUX: Assign channel to the Bus Aux input source

NOTE: All inputs selected by the DIP switches are summed - together. For example, for mono (L+R) operation, activate both the Bus L and Bus R switches . Take care when setting volume levels, since summed L&R inputs can increase signal gain by up to +6dB .

See pages 18 – 23 for illustrations of different system configurations.
