Precision Power DCX 300.4 Stereo Amplifier User Manual


 
QBASS PLUS
On
DCX 600.4
,
DCX 800.5
, and
DCX 1000.4
amplifiers, we’ve taken
bass control to a higher level with
QBASS PLUS
TM
. The two
QBASS
TM
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. On the rear end plate you will find the
QBASS
TM
level
control and plug-in for an optional
QBASS REMOTE
TM
dash
mounted level control. Adjust the level control clockwise for up to
+18dB of boost at your selected frequency.
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.
The
PrecisionPower DCX
TM
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 the
DCX
amplifiers is now positioned before the
crossover circuit. In doing this,
PrecisionPower
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
PrecisionPower
TM
dealer for more information!
