High Level Speaker Wire Connections - Definitive Technology ProSub 60 Owner's Manual

create a very steep crossover slope. Usually, if your receiver or decoder
already has a built-in low pass crossover, you should turn the low pass
control on your ProSub 60 to 150. Also, these subwoofer outputs tend to
have less gain than main line level outputs, thus the gain control on your
subwoofer may need to be adjusted accordingly for proper balance.
For a slight increase in gain, however, you can use a standard, RCA-type
stereo Y-connector to split the mono output into separate left and right
inputs on the subwoofer. Use the LFE input on the subwoofer to hook the
subwoofer up to the LFE (low frequency effects) output on Dolby Digital
AC-3 * decoders, receivers, etc. You can hook the L and R low level
inputs on the subwoofer up to the L and R outputs on your receiver,
decoder, etc. at the same time as hooking the LFE input up to the LFE
output in order to reproduce the bass of all three channels with
the subwoofer.

High Level Speaker Wire Connections

Your Definitive Technology ProSub 60 subwoofer can also be hooked
up via high level connections. In this situation, you have the option of
running your main speakers "full range" or rolling off the low end by
using the high pass filter built into the subwoofer. For high level wiring,
your interconnects are simply equal distance lengths of high quality
speaker cable.
