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 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.
