EQ4
After Dark
. At lower volume levels human hear-
ing is less sensitive at the frequency extremes (deep bass and very high
sounds). In order to compensate when you must play the system at lower
volume levels, EQ4 has been designed to raise the overall bass output of
the sub slightly. The result will be a fuller and richer sounding bass at low
volumes. EQ4 is designed for both music and movies. It can also be used
to help compensate for lack of bass at the listening position.
REF
- This resets the EQ to fl at response and the also resets the volume
trim to 0dB.
LEVEL TRIM and MUTE
- The
and
buttons let you change
the total output level of your subwoofer to compensate for soundtrack
variations and your personal preferences. Each push of the button results
in a 1dB change above or below the
preset reference set with the BASS
LEVEL control. The LEVEL TRIM
readout on the amplifier indicates
the level of adjustment in dB.
Pressing the MUTE button turns off
the volume of the PedWoofers. Pressing it again returns the volume to
its previous setting.
Direct Access Connector
Located on the rear panel, this port and the corresponding male plug
(shipped installed in the port) is for use with a hard wired remote control
system using electronic or mechanical switching. Each contact function
is labeled. To access the control functions use a normally open connec-
tion. Momentary closure will activate each function. The LEVEL TRIM
function will respond in 1dB steps to a single contact closure while con-
stant closure will result in continuous steps to the maximum of ± 10dB.
The REF EQ and REF volume reset functions each have their own set
of contacts.

IMPORTANT: SAVE YOUR BOXES!
If you can do so, save the
carton, packing pieces and plastic bags that came with your sub-
woofer. They will be useful in case you move or have to ship your
subwoofer for any reason. In any case, save all packing materials
until you are certain that the system has suffered no damage in
shipment. If you fi nd such damage, either visible or internal, con-
tact your dealer immediately for the proper return procedure.
