Directed Electronics A1200/4 - Manual (Page 25)

CAUTION: QBASS PLUS TM should only be used in systems with a
strong subwoofer section. +18dB is a tremendous amount of bass
boost and may damage your speakers or create excessive distortion
if abused.
The optional QBASS REMOTE TM : This boost control can be
mounted in the dash and will supersede the boost control on the
endplate.
These PrecisionPower amplifiers no longer need an optional
QPORT TM to connect multiple QBASS PLUS TM equipped amplifiers
while using one QBASS REMOTE TM . The new QBASS PLUS TM
circuitry in these amplifiers is now positioned before the crossover
circuit. In doing this,
Precision Power TM engineers have allowed you
to daisy chain your RCA output to the next amplifier input, causing
the first amplifier’s
QBASS REMOTE TM to become the master
control amplifier. See your authorized Precision Power TM dealer for
more information!
