R12DT SUBWOOFER

CONNECTION OPTIONS

Note: Choose Method A, Method B or Method C con- nection option. DO NOT combine them; choose only one.

Method A (Most desirable)

This configuration will have the best result for a home theater system. If your preamp receiver or processor has a subwoofer or LFE (low frequency effect) output jack that is variably controlled by the master volume con- trol, use a single RCA audio cable to connect that output to the subwoofer’s LFE in jack. This method bypasses the subwoofer’s internal crossover.

METHOD A

Method B

This method provides better sound quality and is pre- ferred over Method C. The preamp (variable line level) outputs from the receiver carry the full range of audio signal frequency and the R12DT will use the active crossover to filter out the mid- and high-range frequen- cies, those which the subwoofer is not designed to reproduce.

Note: If the subwoofer is plugged into a different electri- cal circuit from that which supports the rest of the audio system, a ground loop may result. This causes a 60Hz low frequency hum. This can be eliminated by using the same electrical circuit or by inserting a ground loop iso- lation filter in line with the RCA cables.
