Controls
Volume: This control allows you to adjust the gain of the Subwoofer relative to the rest of your system. Many
listeners make the mistake of setting subwoofers too loud, which can cause bloat as well as loss of detail and
musicality. A properly calibrated subwoofer should blends in with the speakers and does not call attention to
itself. To properly set volume:
► Turn down the volume control on the CS-10 to its lowest position (counter-clockwise).
► Set the Low Pass Filter to where your main left and right speakers play down to. Example: If your L&R
speakers cut off at 70Hz, set your LP on the sub with a slight overlap, then do fine adjustments from there.
► Turn on your audio system, including the CS-10. Play some music you are familiar with and set your receiv-
er/preamplifier volume to a comfortable listening level.
► Slowly increase the volume of the CS-10, listening for proper frequency balance. When balanced, you will
hear improved bass extension, but not be aware that it is coming from the subwoofer.
From this point on, the volume control on your receiver/preamplifier will control the overall volume of your sys-
tem, including the subwoofer.
LOW PASS FILTER: This control determines the upper-limit frequency the subwoofer will reproduce. For
example, setting the filter at 100Hz will cause the subwoofer to reproduce only frequencies below 100Hz. The
Low Pass Filter is continuously variable between 40Hz (low bass) and 180Hz (upper bass), to accommodate
different speakers.
SUBWOOFER PHASE: This switch sets the phase of the subwoofer at either the 0° position (normal phase)
or the 180° position (reverse phase) to achieve the smoothest possible bass response in your system.
This phase-reversing option is important because when bass frequencies come from both the subwoofer and
the main speakers, peaks and dips in the frequency response can occur at the listening position. In these
cases, reversing the subwoofer phase can improve blending and balance.
To properly set the Subwoofer Phase:
► Play familiar music, reversing phase settings. Listen from your usual position.
► Avoid evaluating while standing above the subwoofer or amplifier; sound at the listening position will be
significantly different.
►The correct setting is the one in which the bass is the loudest at the listening position.
Auto Standby
There is no power switch on the CS-10 and SS-10. The auto standby feature automatically switches your
CS-10 into minimum-power mode (i.e. sleep) whenever no signal is present for 20 minutes. When a signal is
received, it immediately turns on again. As AUTO Mode is automatic, it requires no adjustment, nor is there a
need to turn the subwoofer on and off every time it is used.
