QBASS PLUS ™
Q BASS PLUS ™
On the PC1800 amplifier, we've taken bass control
to a higher level with Q BASS PLUS ™ . The two Q BASS
switches (labeled 1 and 2) on the front end of the
amplifier allow you to select one of four frequency centers
30Hz, 36Hz, 44 Hz and 60 Hz. 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
Q BASS ™ level
control and the plug-in for an optional Q BASS REMOTE ™
dash mounted level control. Adjust the level control
clockwise for up to 18dB of boost at your selected
frequency and Q.

CAUTION: Q BASS PLUS ™ should only be used in systems with
strong subwoofers. 18dB is a lot of bass boost and could damage full
range speakers.
Optional Q BASS REMOTE ™
This boost control can be mounted in the
dash and will supersede the boost
control on the endplate.
Optional Q PORT ™ expansion
module allows one boost control
to operate multiple amplifiers. Each
Q PORT ™ has outputs for four amplifiers
as well as to another Q PORT ™ for greater
expansion. See your Authorized PrecisionPower Dealer
for more information!
