Input Section
This XDi ampli er in equipped with a Balanced Input Stage that is compatible with any analog source including Balanced
and Unbalanced RCA, Common ground speaker level output or BTL (Bridged Tied Load) outputs common on many OEM
headunits. The speaker level input plug included with this ampli er are intended to be used with speaker level outputs and
include a divider network to reduce the level of the OEM
system. If you are integrating into an OEM systems
balanced or common ground line level signal you should
not use these Pigtails. In this case it is recommended that
you use an appropriate RCA cable with 1 set of ends
removed as inputs for the ampli er.
Gain
Because of the wide range of head unit output con gurations all ARC Audio ampli ers have an adjustable input sensitivity
or "Gain" . The gain is not a volume or a power limiting control like a throttle. It makes the amp more sensitive to input from
the stereo. With the gain up the amp will reach full output at a lower volume setting on the deck. At higher gain settings
the amp also becomes more sensitive to noise from the car's electrical system. Try to run the gain at the lowest setting
possible for you system.
There is no correct gain setting. Because speakers require
di erent power demands to reach the same output, the
gains most often need to be used to compensate for these
di erences. If you tried to set all the gains at half way you
would probably nd the system didn't sound very good.
Using good judgment and listening carefully to each speaker
is still the best way to tune a system.
Crossover Controls
A crossover is a device that removes unwanted frequencies from a speaker or ampli er. A tweeter can easily be
destroyed by bass notes if they are not ltered out. Likewise a subwoofer will not sound natural if it is playing midrange
notes. A crossover removes these sounds from the
speaker. As you might guess, careful adjustment is need
to ensure that all the speakers are playing the right
sounds and that you are left with no "holes" or low spots
in the frequency response.
Bass Boost
This amp has an adjustable Bass Boost that is directed to the front speakers. When laying out your system, if you plan to
use Bass Boost (Example: Running a Bridged Subwoofer), connect those speakers to the front channels. Begin your adjust-
ments at a low volume. If you do not hear any improvement
then the woofer does not need any boost. Use Bass Boost
carefully. The demands on power output are tremendous.
Try to minimize the use by changing woofer position or the

screws from nameplate
