Precise Frequency Selector Electronic
Crossover
The inclusion of an electronic
crossover in an amplifier
allows for efficient setup and
configuration of an audio system. It also allows
that amplifier to be used with factory or after
market source units that do not have electronic
crossovers in them, either high- or low-pass.
One drawback of a conventional electronic
crossover is that it can be difficult to precisely
set the crossover frequency because the
potentiometer is nearly infinitely adjustable. Also,
many potentiometers are only labelled at the
top and bottom of its frequency range, making
selecting something in the middle even more
difficult.
Clarion provides a simple and elegant solution
to accurately setting crossover points with our
PFS (Precise Frequency Selector) crossover
adjustment. The potentiometer on the APX2180,
APX4360, DPX2250, DPX1800 and DPX11500 has
41 detented positions. Using the chart supplied in
the owner’s manual of each amp, you can select
a specific crossover frequency, then to set it,
turn the adjustment potentiometer the according
number of clicks, and you are done.
One of the many benefits of this feature surfaces
when you are building a multi-amp system. With
conventional crossover controls, you could end
up setting a subwoofer amp to 70Hz when you
were aiming for 85Hz and end up at 100Hz on
the mids and highs amp. The result would be a
system that lacks dynamics and sounds muddy.
PFS makes accidental under- or over-lapping of
crossovers a thing of the past.
Input Voltage Selector
Conventional gain adjustment
systems have inherent limita-
tions. Because users want a
wide sensitivity range (0.2V to 8.0V for example),
a conventional gain control creates large differ-
ences in left and right output - called channel
imbalance. This is due to variances and tolerance
2006 Amplifier Line Overview
For 2006, Clarion has introduced an entirely new
line of amplifiers, designed from the ground up
to compliment one-another in terms of features,
performance and design. The 2006 amplifier
line takes a three tiered approach to features,
technology and design.
Model Class Description Power
APX2120 AB 2-Channel 2 x 60W
APX4240 AB 4-Channel 4 x 60W
APX1300 AB Mono 1 x 300W
APX2180 AB 2-Channel 2 x 90W
APX4360 AB 4-Channel 4 x 90W
DPX2250 G 2-Channel 2 x 125W
DPX1800 G Mono 1 x 800W
DPX11500 G Mono 1 x 1500W
The entry-level amplifiers offer increased power
production over the previous models, as well
as featuring a cosmetic theme that integrates
with the top two amp series. The feature set
on our entry level amplifiers was designed to
allow installers to get these amps installed into
a vehicle quickly and tune them without the
need for complex instruction manuals. These
features allow for elaborate system design and
configuration.
The top two series of amplifiers (Illuminated and
Class G) are designed around a set of features
that allow for more accurate installations, class
leading transparency, dynamics, musicality and
efficiency. The APX2180 and APX4360 offer
benchmark sonic transparency, frequency and
phase response and installation / configuration
features. The new DPX amplifiers feature state-
of-the-art Class G designs that offer the ultimate
mix of sound quality and efficiency, minimizing
the load on a vehicles electrical system.
