For extra BOOM from your system, we've developed the
QBASS
™
bass control circuit. The
QBASS control is located
to the left of the speaker outputs, and allows you to add up to
12dB of boost centered at 40Hz by rotating the control clockwise.

QBASS

Is a standard feature on the
PC4200/PC4400.

PLUS

On
PC4800 and PC6600 amplifiers, we've taken bass control
to a higher level with
QBASS PLUS
™
.
The two
QBASS switches
(labeled 1 and 2) on the front end of the amplifier allow you
to select one of four frequency centers - 30Hz, 36Hz, 44Hz
and 60Hz. The Q SELECT switch determines the width of
boosted frequencies. A 'Q' of 2 (switch out) will give you a
wide boost while a 'Q' of 4 will boost a narrow range of
frequencies. (See chart below.) On the rear end panel you
will find the
QBASS PLUS
™
level control and the plug-in
for an optional
QBASS REMOTE
™
level control. Adjust the
level control clockwise for up to 18dB of boost at your
selected frequency and Q.
