A/B Class Amplifiers
If you’re looking for raw power, then look no
further. PowerBass’ mission has been to
develop and refine audio products that satisfy
the most demanding enthusiasts. The XA
PowerBass amplifiers deliver pure, clean power.
The XA amplifier starts with a low profile, high
density extruded aluminum heatsink for
maximum heat dissipation. We then add
custom tooled brass terminal speaker and
power terminal blocks for excellent
conductivity, and then offer low level inputs
AND outputs that send a full range signal on to
additional amplifiers for easy system design.
Inside the amplifiers, we use a PWM (Pulse
Width Modulated) switching power supply and
MOSFET transistors for increased output
voltage. To make sure that the proper signal
gets to your speakers, we have an adjustable 12
dB/octave high pass crossover with a range 50
– 250Hz and a low pass crossover with a range
of 40 – 400 Hz to allow for multiple
applications. To get that low bass bump, we
equip the XA amplifiers with an EQ with 18dB
of boost at 45 Hz. As you will find out, the XA
amp will provide your PowerBass speakers
with plenty of clean power.
The D Class range of XA amplifiers are
designed to run subwoofers with less power
demand on your vehicle’s electrical system.
The XA amplifiers come fully equipped with
features to run your subwoofers no matter
what size or the type of music you listen to.
First a 24-dB/octave crossover to cut the high
frequencies out of your subs and concentrate
all of the amplifiers into the subwoofers
intended frequency range. In addition to
cutting high frequencies, we also include a
subsonic filter to cut frequencies too low to be
heard and waste amplifier power. The
included remote bass control allows control of
the volume of the subwoofers when you need
to increase the output of the subwoofers. For
SPL applications, the XA amplifiers can be
strapped together for serious power to
individual voice coils - or just because.
