CAUTION: QBASS PLUS™ should only be used in systems with a strong subwoofer
section. +18dB is a tremendous amount of bass boost and may damage your
speakers if abused.
Optional QBASS REMOTE™: This boost control can be mounted in the dash and
will supersede the boost control on the endplate.
P r e c i s i o nP o w e rP C X ™ amplifiers no longer need an optional Q P O RT ™ to connect
m u l t i p l e QBASS PLUS™ equipped amplifiers while using one Q B A S S
REMOTE™. The new QBASS PLUS™ circuitry in the PCX™ amplifiers is now
positioned before the crossover circuit. In doing this, PrecisionPower engineers
have allowed you to daisy chain your RCAoutput to the next amplifier input, causing
the first amplifier’s Q BASS Remote™ to become the master control amplifier. See
your Authorized PrecisionP o w e r D e a l e r for more information!
On PCX 2125, PCX 2200 and PCX 2400 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 cen-
ters 30Hz, 36Hz, 44Hz and 60Hz, with a Q-Factor of 2. On the rear end plate you
will find the QBASS™ level control and the plug-in for an optional Q B A S S
R E M O T E ™ dash mounted level control. Adjust the level control clockwise for up to
+18dB of boost at your selected frequency.
