2010 Amplifier Line Overview
With a heritage of power, performance, and quality that
spans many decades, Clarion proudly introduces our
most sophisticated amplifier line ever. The entire line
offers the kind of power and performance that today’s
customers demand.
Clarion does not ignore the need for an amplifier to
look cool, but we put sound quality and performance at
the top of our list. We will not for go musical transpar-
ency and control for size or a cosmetic feature.
Instead, we embrace the latest in power supply
technologies to make our amplifiers simultaneously
musical, efficient, and compact.
Clarion amplifiers are developed to compliment
one-another in terms of features, performance, and
design. These features exist to help installers
complete the integration of these amplifiers into a
vehicle faster and more accurately. Likewise, these
features also help to improve the performance of the
amplifier.

Precise Frequency Selector Electronic
Crossover
The inclusion of an electronic
crossover in an amplifier
allows the speaker to receive
the musical information that it can produce properly.
This means that sound quality from the speaker is
improved and power handling in smaller speakers is
increased dramatically.
One drawback of an electronic crossover which allows
the crossover frequency to be adjusted through the
use of a potentiometer is that it can be difficult to
precisely set the crossover frequency. This is because
the potentiometer is nearly infinitely adjustable. Many
crossover controls are only labelled at the top and bottom
of their frequency range, making selecting a frequency in
the middle of the adjustment range nearly impossible.
Clarion provides a simple and elegant solution for
accurately setting crossover points with our PFS (Precise
Frequency Selector) crossover. The potentiometer on the
XH7110, XH5210, and XH5410 amplifiers have 41
detented positions. Using the supplied charts, you can
select a specific crossover frequency, then to set it, turn
the adjustment potentiometer according number of clicks,
and you’re done.
One of the many benefits of this feature surfaces when
you are building a multiple amplifier system. With
conventional (non PFS) crossover controls, you could
end up setting a subwoofer amp set to 70Hz when you
were aiming for 85Hz and end up at 100Hz on the mids
and highs amplifier. The result would be a system that
lacks mid-bass dynamics and makes the bass frequen-
cies sound disconnected from the mids and highs. PFS
makes under/over-lapping of crossovers history.
Input Voltage Selector Gain Control
Conventional amplifier gain (or
sensitivity) adjustment systems
have inherent limitations. These
controls utilize ganged or stacked potentiometers to allow
you to match the power production capabilities of the
amplifier to the signal strength of the source unit that is
feeding it. To allow an amplifier to be used with as many
different sources as possible, the sensitivity range should
be as wide as possible.
Because the gain control uses several potentiometers
that are connected together (ganged), the exact resis-
tance of each of these devices may not match the next
one. The result is one channel of the amplifier will be
louder than the other. This is called channel imbalance.
To combat channel imbalance, Clarion has implemented
IVS (Input Voltage Selector) technology on the XH7110,
XH5210, and XH5410 ampliifers.
IVS dramatically reduces channel imbalance by imple-
menting a switch that controls the gain range: 0-0.6v,
0.6-2v, 2-8v. This switch is used in conjunction with a
narrow-range adjustable potentiometer for fine tuning.
The result is a reduction in maximum potential channel
imbalance, improved imaging, and a more accurate
soundstage.
