POWER & SIGNAL CONNECTIONS
Multi-Channel/Stereo Applications- Line Level Connection
This connection method is for multi-channel/stereo applications where the pre/pro has L/R
line level outputs.
• Using high quality and shielded RCA cables, connect the L/R line level outputs
from the pre/pro to the L/R line level inputs on the subwoofer.
• If the pre/pro does not have a spare set of line level outputs, a 1 M-2F Y-adapter
may be used on each pre/pro output in order to split the signal and allow connection to both
the loudspeaker amplifier and the subwoofer amplifier.
• Adjust the low pass filter to blend with the natural roll-off frequency of your
loudspeakers. The manufacturer's rated bass extension for your loudspeakers is a good
starting point, but final blending is best done by ear.
• Adjust the gain to blend with the level of your loudspeakers.
• Adjust the phase control to obtain the most coherent and stable soundstage and
transition between the loudspeakers and the subwoofer.

With this connection method, you do have the option of using the subwoofer to high pass
the signal being sent to the loudspeaker amplifier. The line level outputs feature a fixed 80
Hz 12 dB/octave high pass filter. In order to high pass the loudspeakers, connect the pre/pro
outputs to the subwoofer line level inputs. Then connect the subwoofer line level output to
the loudspeaker amplifier inputs. Adjust the low pass filter on the subwoofer to 80Hz and
then do final low pass blending by ear.
