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

BASS

PLUS

™

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.
