ESI SW8000 - Manual (Page 10)

Moving the turntable or the speakers may remedy this problem. Or try placing an anti-
vibration pad under the turntable.
a. Level setting
With the “Level” control the volume of the subwoofer is set to properly match the satellite
speakers. You can start with setting at 12 O’clock position of Level Control.
If the Subwoofer is placed on the floor against one wall in a normal room, the Subwoofer
sound pressure could be increased 3dB than placed on the freestanding floor. On the other
hand, if the Subwoofer is placed in a corner, the Subwoofer sound pressure could be
increased by another 3dB comparing to placing on the floor against one wall. You can use
the Level control to set the Sound Pressure of Subwoofer under different placements to
match Satellite sound pressure properly.
b. Setting of upper frequency limit for Subwoofer
With the control, “crossover frequency of Subwoofer”, an adjustable, 2
nd
order (12
dB/Octave) low-pass filter gives an upper limit between 50 and 180 Hz.
If the Subwoofer SW8000 connected to Professional Audio Console with Bass management,
the Subwoofer control should be set to 180 Hz as the crossover will be handled by the
Console. (Or the filter of SW8000 will add together with the filter of Console and generate
wrong frequency response at crossover area.
If the subwoofer SW8000 connected to Professional Audio Console without Bass
management, the Subwoofer control should be set together with low frequency limit of
Satellite Control.
c. Setting of lower frequency limit for Satellite speakers
The purpose of this Satellite control is to match the satellite cut off frequency to the upper
frequency limit of the Subwoofer. This control – one for each channel – is adjustable
between 50 and 180 Hz.
If the Subwoofer SW8000 connected to Professional Audio Console with Bass
management, the Satellites control should be set to 50 Hz as the crossover will be handled
by the Console. (Or the filter of SW8000 will add together with the filter of Console and
generate wrong frequency response at crossover area.)
