Procedure
ShowMatch array loudspeakers can be powered either independently or in parallel pairs.
Independent Loudspeakers
For independent loudspeakers use a pair of PowerMatch output channels in V-Bridge (LO-Z) mode for the LF (low frequency) section of the loudspeaker and a Mono (LO-Z) channel for the HF (high frequency) section.
Note that the input NL4 connector on the ShowMatch loudspeakers are wired with LF on 1+/- and HF on 2+/-.
The example below details wiring of a 4-box ShowMatch Array.
Parallel Pairs of Loudspeakers
For parallel pairs of loudspeakers use four PowerMatch output channels in Quad (LO-Z) mode for the LF (low frequency) section of two loudspeakers and use a pair of output channels in V-Bridge (LO-Z) mode for the HF (high frequency) section. The two NL4 connectors on the ShowMatch loudspeakers are wired in parallel. Connect a 4-conductor cable from the first box to the second box to wire in parallel.
Note that the input NL4 connector on the ShowMatch loudspeakers are wired with LF on 1+/- and HF on 2+/-.
SMS118 Subwoofers
For SMS118 subwoofers use four PowerMatch output channels in Quad (LO-Z) mode for each subwoofer.
