LevelKnob
Setting the level too high will cause the bass to seem bloat-
ed and is the single most common cause of bad sounding
subwoofers. A rule of thumb is that the subwoofer should
not draw attention to itself, but should simply make the sys-
tems low end seem more extended and accurate.
PhaseControlSwitch
The phase control is entirely dependent on the size and
configuration of your listening environment, the placement
of the unit, and your seating arrangement. Due to the way
bass sound waves develop in different rooms, there is
no rule of thumb for setting phase. For instance, if your
room has a peak at the subwoofer crossover area, you
may wish to set the phase so the actual acoustic outputs
of the subwoofer and main speakers are out of phase.
Experiment, try different settings and be patient.
Crossover
When the CW10 is connected in multi-channel mode (via
its LFE input), the crossover switch should be set to 'Bypass
(LFE In)' so that the low pass filter is not active and your
processor handles the bass management.
When connected in 2-channel mode (via its left and right
inputs), the crossover switch should be set to 'Variable (L&R
In)' so that the low-pass filter is active.
LowPassFilterKnob
When the CW10 is connected in multi-channel mode (via
its LFE input), the low pass filter is not active and your pro-
cessor handles the bass management. When connected
in 2-channel mode via its line level left/right input, the
low-pass filter is active.
As a general rule the low pass filter should be set equal
to approximately 70% of your speaker’s lowest frequency
response. Remember, this is a general rule. We advise
that once you try the recommended setting using the for-
mula above, you should try the surrounding settings to see
which sounds best.
StatusLED (not shown above)
When the status LED (located on the front bottom of the
subwoofer) is blue, the subwoofer is on. When the status
LED is off the subwoofer is in standby mode.
MasterPowerSwitch (not shown above)
Located on the back panel of the subwoofer, the Master
Power switch must be set to 'Auto On' for the subwoofer
to operate. When set to 'Auto On' the subwoofer will
automatically enter a power saving mode when no audio
signal is detected. The subwoofer will automatically come
out of power saving mode when a signal is detected.
