Accepts line level output specified for a powered subwoofer only. The SUB
MONO OUT from th Samson DMS80 would connect to the MONO INPUT.
5. STEREO INPUT FILTER (LEFT)
Accepts line level out from the left channel of a stereo source.The built-in
low pass filter cuts frequencies from 100 Hz up, therefore making it possible
to use the S40 with any stereo line source.
6.
STEREO INPUT FILTER (RIGHT)
Accepts line level out from the right channel of a stereo source.The built-in
low pass filter cuts frequencies from 100 Hz up, therefore making it possible
to use the S40 with any stereo line source.

INSTALLATION
1. Unpack the S40. Inspect all items for quality of appearance and physical
damage. If shipping damage has occurred, immediately notify your dealer.
2. For best sub frequency response, place the S40 on the floor with the rear
(ported side) facing a corner or wall, or under a work station or desk.
3. Either connect a line level (non amplified) sub mono out to the MONO
INPUT of the S40, or connect line level left and right outputs to the left and
right STEREO INPUT FILTERED respectfully.
4. Making sure the POWER SWITCH is in the off position and the SENSITIVI-
TY control is turned completely counter-clockwise, connect the IEC power
cord to the AC INLET and a grounded AC outlet.
5. Power up your stereo source and the S40. Increase the SENSITIVITY con-
trol on the S40 until a good balance between your stereo speakers and the
subwoofer is achieved.
