Power

Plug the wall transformer into any standard 120 VAC outlet.  

 Note: Be sure the volume

control on your receiver or preamp is turned down when power is applied to the SVS-
1B, or turn all components on together.

Bypass Mode

With the MODE SWITCH in the “OUT” (bypass) position (ACTIVE LIGHT is off), there is
no change to the audio signal.   The SVS-1B will work with power on or off in this mode.
Likewise, adjustment of the Volume Stabilization switch will not have any affect.

Active Mode

With the MODE SWITCH in the “IN” position (ACTIVE LIGHT is on), the SVS-1B Volume
Stabilizer is in the signal path.  The Volume Stabilization switch allows you to adjust
either some volume stabilization (at the Norm position) to maximum volume stabilization
(at the Max position).
The MODE SWITCH toggles volume stabilization on and off.  Typically, the volume will
be slightly louder in the active position.  This is because most music is recorded below
the maximum level so the peak music does not saturate or clip.
The Volume Stabilizer has the biggest impact on music and video sound tracks when the
softer passages are played.  The volume and the sound quality will improve in the active
mode.  When the music is recorded “hot” (or very loud on whatever input is selected)
then you will actually hear the volume decreased by the Volume Stabilizer.  However,
this is done automatically for you so you can just enjoy the music.
