Setting the Aperion Audio Intimus S8-APR Subwoofer
In addition to the high and low-level speaker connections on the rear of your
subwoofer, you will see two round knobs and three switches. The first knob,
labeled “level,” controls the subwoofer’s volume. The second knob, “crossover
frequency,” sets the crossover frequency. As a starting point, set the receiver
crossover at 80Hz and the subwoofer crossover between 80Hz-120Hz.
The power switch has three settings - on, off and auto. When the switch is
set in the “auto” setting, it will automatically turn the sub on when a signal
is present. You’ll know the subwoofer is on because the power lamp will
be illuminated red (when a signal is present it turns green). The “phase”
switch reverses the subwoofer’s polarity. If the distance from the sub to the
listener is significantly different than the front and center speakers (>3’),
try using the phase reverse switch to see if it improves the bass response.
The S8-APR has a switchable voltage control. Please be sure to select 120V
for use in the USA.
The illustration to the right shows
a recommended starting point for
settings. You will want to adjust
these based on personal preference
and room dynamics.
