CONNECTING & CONTROLLING YOUR SUBWOOFER
High Level (Speaker Level) Connection - Multi-Channel/Stereo Applications
This connection method is for multi-channel/stereo applications where the integrated
pre/pro/amplifier only has high level (i.e., speaker level) outputs.
Using high quality speaker wire, connect the L/R speaker level outputs from the
integrated amplifier to both the loudspeakers and the subwoofer L/R speaker level
inputs on the subwoofer. This will require running two sets of wires from the outputs
of the integrated amplifier.
Adjust the low pass filter to blend with the natural roll-off frequency of your loudspeak-
ers. 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.
