INSTALLATION APPLICATIONS
This product is designed for operation in
vehicles with 12V, negative-ground electrical
systems. Use of this product in vehicles with
positive ground and/or voltages other than 12V
may result in damage to the product and will void
the warranty.
This product is certified or approved not
for use in aircraft.
PLANNING YOUR INSTALLATION
It is important that you take the time to
read this manual and that you plan out your
installation carefully.
Safety Considerations:
Your CleanSweep™ needs to be installed in a
dry environment and in a manner which does not
interfere with your vehicle’s safety equipment (air
bags, seat belt systems, ABS brake systems, etc.).
You should also take the time to securely mount
the CleanSweep™ processor using the supplied
screws so that it does not come loose in the event
of a collision or sudden acceleration / deceleration.
Stupid Mistakes to Avoid:
• Check before drilling any holes in your vehicle to
make sure that you will not be drilling through a
gas tank, brake line, wiring harness or other vital
vehicle system.
• Do not run system wiring outside or underneath
the vehicle. This is an extremely dangerous
practice which can result in severe damage to
your vehicle and person.
• Protect all system wires from sharp metal
edges and wear by carefully routing them,
tying them down and using grommets and
loom where appropriate.
• Do not mount this product in the engine
compartment, under the vehicle, on the
roof or in any other area that will expose it
to the elements.
SERIAL NUMBER
In the event that your CleanSweep™ CL441dsp
requires service or is ever stolen, you will need to
have a record of the product’s serial number. Please
take the time to enter that number in the space
provided below. The serial number can be found on
the bottom panel of the unit and on the packaging.
Serial Number:
PROTECT YOUR HEARING !
We value you as a long-term customer. For
that reason, we urge you to practice restraint in
the operation of this product so as not to damage
your hearing and that of others in your vehicle.
Studies have shown that continuous exposure to
high sound pressure levels can lead to permanent
(irreparable) hearing loss. Automotive audio
systems are capable of producing such high sound
pressure levels. Please limit your continuous
exposure to high volume levels.
While driving, operate your audio system in a
manner that still allows you to hear necessary noises
to operate your vehicle safely (horns, sirens, etc.).

3) The digitally corrected signals are then
converted back to analog audio and sent
to your aftermarket amplifiers through two
pairs of low-distortion, 8 volt (RMS) line-
level outputs.
4) The CL441dsp provides a simple rotary
knob with stops at both ends to control
the master system volume at the outputs
of the processor unit for the OEM (factory)
source and the Auxiliary source. The
master volume eliminates the effects of any
equalization that is dependent on the OEM
volume control position and allows a high
signal-to-noise ratio to be maintained in the
system. When pressed, the Master Volume
Control also selects between the OEM and
Auxiliary source. A dash-mountable status
LED changes color to indicate OEM or AUX
input modes. These small items can be easily
mounted within reach of the driver.
5) The CL441dsp can be deployed in signal-
sensing mode, powering up and providing
a 12-volt turn-on signal for aftermarket
equipment whenever signal is detected.
It can also be activated by a conventional
12-volt trigger, if the OEM system
provides one.
PRODUCT OVERVIEW
The CleanSweep™ CL441dsp is a sophisticated
digital audio processor that performs the
following functions:
1) It accepts virtually any analog audio signal,
from low-voltage line-level to high-power,
amplified speaker-level, via its four differential-
balanced inputs. With totally automatic level
compensation, the CL441dsp converts the
two or four connected analog signals to digital
audio with 24 bit effective resolution.
2) The CL441dsp applies its 32-bit SHARC®
DSP processor to automatically equalize
each of the four channels with 30 bands of
equalization (120 bands total), effectively
correcting the response of almost any
factory-equalized, full-range signal. These
digital-domain corrections will range from
subtle to dramatic, depending on the degree
of equalization engineered into the factory
audio system.
To accomplish this complex feat, you
simply load the supplied CleanSweep™
Calibration CD into the factory-installed
CD player, set its volume control between
1/2 and 3/4 of maximum, play the
designated calibration track and then press
the “Calibrate” button on the top of the
CL441dsp processor. Approximately 20
seconds later, the processor is finished
analyzing and equalizing the factory-installed
source’s response and stores the corrections
in non-volatile flash memory.
