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 ex tremely 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.

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 differential­balanced 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 factor y
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.

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) line­level 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 Auxiliar y 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 signal­sensing 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.

POWER CONNECTIONS

Before installing the CL441dsp, disconnect the
negative (ground) wire from the vehicle’s battery.
This will prevent accidental damage to the system,
the vehicle and your body during installation.

The CL441dsp has a 4-pin inline jack located
next to the line output jacks. This jack accepts
the following connections (a wiring harness with a
mating plug is included):

“+12 V”: Constant +12V

“GND”: Chassis Ground

“IGN”: Switched +12V

“REM.OUT”: Amplifier turn-on (+12V)

Since the CL441dsp does not draw very much
current during operation, 18 AWG - 16 AWG
wire is ample for making all of these connections.
Use good-quality crimp connectors (or solder and
heatshrink tubing) to join the harness leads to any
extended wires. Any wires run through metal
barriers (such as firewalls), must be protected with
a high quality rubber grommet to prevent damage
to the insulation of the wire. Failure to do so may
result in a dangerous short circuit.

Ideally, the “+12V” (constant) and “GND”
(chassis ground) connections should be run to
the same distribution points that the amplifiers
use for their power and ground connections. This
minimizes the possibility of noise in the system.

The “IGN” connection is designed to do the
following: the CL441dsp will only turn on when
+12V is present at this connection. Conversely,
the CL441dsp will shut off as soon as +12V is
removed from this connecton. We recommend
that you connect this wire to a 12 volt circuit in
the car that is only energized with the key in the
“Accessory” (ACC) or “Ignition” (IGN) positions.
Since the CL441dsp is designed to control the rest
of the aftermarket system’s turn-on and turn-off
functions, this will ensure that the audio system
will only operate with the key in ACC or IGN
positions. See “Signal Sense Modes” section on
Page 9 for further options.

The “REM.OUT” (Remote Output) connection
provides turn-on voltage to other aftermarket
equipment (just like an aftermarket head unit’s
remote turn-on lead).

FUSE REQUIREMENTS

The +12V constant wire on the CL441dsp
power harness has an inline 1 amp, fast blow AGC
(small glass-bodied) fuse for protection of the
unit. Do not remove this fuse or replace it with a
different value of fuse.

OUTPUT CONNECTIONS

Four RCA-type jacks provide four-channels
of analog audio output to feed your aftermarket
system. These are located next to the “Power
Connector” and are clearly labeled for each channel.
Think of them as your new head unit outputs.

OUTPUT AND POWER CONNECTION DIAGRAM

JL AUDIO CleanSw eep™ CL 441dsp 5

OEM INPUT CONNECTIONS

The CL441dsp accepts up to four channels
of input from an OEM audio source via the 8-pin
plug located on one end of the main processor.
A color-coded harness is included for connection
to this 8-pin plug. The input architecture is set up
in a differential-balanced configuration, making
these inputs compatible with virtually any analog
audio signal.

Refer to the wiring diagram on Page 7 for channel
and polarity information.

It is vital to observe correct electrical polarity
on each channel when making input connections.
Failure to do so can result in significant loss of bass
and other audible problems.

The CL441dsp can accept full-range, analog signals
from virtually all OEM head units and amplifiers.
Depending on the specific architecture of your
OEM system, you will need to choose appropriate
connection points that maintain OEM functionality
and provide appropriate input to the CL441dsp. It is
recommended that you obtain a service manual for
the vehicle you are working on in order to locate
and identify the correct OEM wires. OEM signal
and speaker wires are often twisted in pairs for each
channel, making them easy to identify in a harness.
You can also observe the color codes of the wires
connected to the OEM speakers and trace those
back to the OEM head unit or amplifier harness.

IMPORTANT!

The OEM audio signals connected to the OEM
inputs of the CL441dsp must be full-range (20 Hz

- 20 kHz bandwidth) or very close to it. Feeding
crossed-over signals into the CL441dsp will result
in noisy output or complete failure to calibrate.
This error condition is indicated via flashing red
lights after the calibration has been attempted.

Signals that are crossed over must be summed
to full range using appropriate summing devices
prior to being connected to the CL441dsp. Please
contact your authorized dealer for assistance if
this situation exists in your vehicle. Never attempt
to sum signals by connecting different channels
together directly!

If only two-channels of full-range audio are
available from the OEM system, the CL441dsp can
be used with only two channels connected (and
will only output two channels of audio).

AUX INPUT CONNECTIONS

One of this product’s best features is the ability
to connect additional sources of your choice
to your audio system. To connect an auxiliar y
source, you will need standard RCA-type audio
interconnect cables. Depending on the source
unit, you may need additional cable adaptors. If
you wish to connect multiple audio sources to
these jacks, you will need an additional source
selector switch between the source units and the
AUX Inputs of the CL441dsp.

If you will be powering the AUX source from
the vehicle, it is a good practice to make the AUX
source’s power and ground connections at the
same point as the CL441dsp power and ground
connections. This minimizes the possibility of
ground-loops and noise in the system. If your AUX
source unit gives you the option of a fixed line
level output or a variable output (controlled by its
volume control), it is recommended that you use
the fixed level output.

A pair of level trim potentiometers on the top
of the CL441dsp chassis will permit you to level­match the AUX source to the OEM level. This
should be done after calibrating the OEM Inputs.
See the “Calibration” section on Pages 9 and 10.

Please note that the CL441dsp will not
equalize the AUX source input in any way. The
AUX source audio is passed, undisturbed, to the
CL441dsp’s outputs.

MASTER VOLUME CONTROL
CONNECTIONS AND MOUNTING

The CL441dsp Master Volume Control serves two
main functions:

1) To control the system volume

2) To switch between the OEM inputs and the
AUX inputs (by pushing in on the knob).
If no AUX source is connected, the knob will
mute / unmute the system when pressed.

For these reasons, you will want to locate the
knob, within easy reach of the driver, on the center
console or dashboard of the vehicle.

To mount the knob, first verify that sufficient
clearance exists behind the mounting sur face for
the control assembly’s small enclosure. Then, drill
a 3\8-inch (9mm) diameter hole in the mounting
surface. Remove the nut and washer from the
threaded collar and inser t the control assembly
from behind the mounting surface. Place the
washer over the shaft and secure with the nut.
Finally, place one of the two supplied knobs over
the shaft, orienting the knob marker appropriately
relative to the rotation range of the control.

A small multi-color LED is also included to
indicate which input mode is selected:

Green = OEM Input Mode

Red = AUX Input Mode

The LED can be mounted at the owner’s
discretion in the front of the vehicle, using the
supplied mounting grommet. To mount the LED,
first ensure that sufficient clearance exists for the
LED body and leads behind the mounting surface.
Then, drill a 8mm diameter hole in the mounting
surface. Insert the LED from behind the mounting
surface (without attaching the mounting grommet).
Snap the mounting grommet over the LED body
and insert it into the hole you have drilled until flush.

Once the LED and Master Volume Control are
mounted, connect the Master Volume Control
harness to the “CONTROL CONNECTOR” port
on the CL441dsp main processor. If the cable length
is insufficient, use the supplied extension cable.

Using the OEM head unit’s volume control
instead of the CL441dsp Master Volume Control:

If desired, the OEM (factory) volume control
can be used to control the master system volume
as long as you accept the following compromises :

a) The factory volume control will not

control the AUX source volume. Only the
CL441dsp’s Master Volume Control can
control the AUX level.

b) There may be a noticeable increase in

system noise (hiss) at lower volume levels,
compared to using the CL441dsp’s Master
Volume Control.

c) There may be significant changes in

frequency response imposed by the OEM
system’s volume-dependent equalization.
These may be objectionable or acceptable,
depending on the car and the desired
performance of the system. In most cases,
OEM systems boost bass and treble at
lower volume settings (can be acceptable)
and often cut bass at higher volume settings
(more objectionable).

If no AUX source is being used and the sonic
compromises of using the OEM control are
acceptable, simply set the CL441dsp Master
Volume Control at full output (fully clockwise) and
hide it in the installation.

SIGNAL SENSE MODES

The CL441dsp is designed to act as a turn­on and turn-off controller for the aftermarket
components in your system. There are two modes
of turn-on operation which can be selected via the
“SIGNAL SENSE” slide-switch located next to the
OEM Input Connector.

SIGNAL SENSE: ON

In most cases, you will want to use this mode
which requires that the “IGN” terminal of the
CL441dsp be connected to a wire with accessory/
ignition-switched +12V. In this mode, the
CL441dsp will only wake up and turn on the rest
of the system when it senses +12 V at its “IGN”
terminal and also senses an input signal from the
OEM audio source. If the vehicle is turned on with
the OEM source unit turned off, the CL441dsp
will remain in standby mode until the OEM source
is turned on and playing. The CL441dsp go into
Standby Mode (off ) one minute after it senses
a loss of input signal or as soon as the ignition is
turned off (whichever comes first).

Note: You must have the OEM source unit
playing in order to listen to the AUX source when
the “Signal Sense” mode is “on”.

SIGNAL SENSE: OFF

With the “Signal Sense” switch in the “off ”
position, the CL441dsp will wake up and provide
+12V at its “REM.OUT” terminal whenever it
senses +12V at its “IGN” terminal (regardless
of whether the OEM source is on or not). This
position can be useful if another device is being
used to toggle the CL441dsp on/off, or if the
OEM system has a conventional +12 V turn-on
output (very rare). The “off” position can also be
used with a manual switch on the wire feeding
the “IGN” terminal for those who desire manual
control of on/off functions. This switch should
be connected to an ignition-switched +12V to
prevent accidental battery drainage. If you decide
to ignore the foregoing and use a manual switch
fed by constant +12V, be aware that forgetting to
shut the system off will result in battery drainage.

CALIBRATION

Once you have made all your system

connections, follow these steps precisely:

1) Turn the CL441dsp’s Master Volume Control
all the way DOWN (fully counterclockwise).

2) Reconnect the vehicle’s battery ground.

3) Turn the OEM head unit on and make sure

it is playing something (radio or CD, doesn’t
matter right now). Set all of the OEM head
unit tone controls at “0” (flat), and the
balance and fader controls at their center
positions. Turn off any factory DSP features,
such as “Concert Hall” or “Stadium” or
music genre-specific equalization settings.

4) Verify that the CL441dsp and all of the

aftermarket equipment have turned on.

5) Slightly raise the CL441dsp Master Volume
Control to verify that audio is passing
through to the aftermarket system. Once
verified, turn the Master Volume Control all
the way down (fully counterclockwise).

6) Insert the included CleanSweep™ Calibration

CD into the OEM CD player, play Track “01”
and set the OEM head unit volume control
between 1/2 and 3/4 of full volume.

7) Using a small pointed tool or a paper clip,

press the “CALIBRATE” button on the top
of the CL441dsp.

8) Wait approximately twenty seconds... lights

will flash in various colors to keep you
entertained and to indicate that calibration is
taking place. After twenty seconds, the lights
will stabilize and indicate whether calibration
has been successful on each channel.

9) If you see four steady green lights (or two if

you only connected two channels of input),
your calibration was successful. If you do
not see steady green lights, refer to the
“Channel Status Codes” section on Page 11
for troubleshooting.

JL AUDIO CleanSw eep™ CL 441dsp 9

10) If you see steady green lights, you can
now proceed to set your amplifier input
sensitivities (handy test tones are included
for this purpose on the CleanSweep™
Calibration CD). Then, balance your
amplifier channels to taste.

11) If an AUX source is connected, use the

“AUX INPUT Level Trim” controls on the
top of the CL441dsp to adjust the level
of the AUX source so that it matches the
level of the OEM source and so that both
channels of the AUX source are properly
balanced. Use similar music or test tones
playing through each source unit for best
results. If the “CLIP” indicator lights flash or
light continuously, reduce the level until they
no longer light up.

12) That’s it ! You’re now ready to enjoy
great sound.

EQ DEFEAT MODE

If you would like to verify the effect of the
CL441dsp’s OEM equalization function, you can
press the “EQ DEFEAT” button on the top of the
unit when it is in OEM Input mode.

In “EQ DEFEAT” mode, the channel status
LED’s will flash green and the CL441dsp’s response
correction is bypassed, allowing you to hear the
raw response of the OEM audio source. The
Defeat Mode will stay engaged for up to five
minutes or until you press the “EQ DEFEAT”
button again.

USING YOUR NEW AUDIO SYSTEM

The “Audiophile Method”:

For best audio per formance you will want to
use the CL441dsp’s Master Volume Control as
your main system volume knob for all sources.
This will maintain linear frequency response at all
volume levels and the best possible signal-to-noise
performance.

Once the CL441dsp is installed and calibrated,
make a note of the specific volume position you
used on the OEM source unit to calibrate the
CL441dsp. From now on, you will operate your
audio system with the OEM control set at this
level. Most source units provide a numerical or
graphic representation of the volume position
on their display. If yours does not, you will simply
need to estimate the position using minimum or
maximum as a reference point and remembering
the degree of rotation from that point.

Leaving the OEM volume control at the
calibration level, you will use the Master Volume
Control for volume adjustment, but you may
continue to use the OEM source unit’s tone
controls, fader and balance controls, if desired.

To select the AUX input, simply press down
on the Master Volume Control Knob. The Source
Indicator LED lights Green for the OEM source
and Red for the AUX source. If no AUX source
unit is connected, the system will mute when
AUX is selected (so, if you’re ever sitting there
wondering what happened to your sound, chances
are you need to press the knob to re-engage the
OEM Input.)

Important Notice for All Users!

Keep in mind that any audible OEM functions that depend on the OEM audio
system will only be audible when the OEM Input is engaged. Driver assistance
systems (like OnStar®), navigation systems, and door chimes on some vehicles are
examples of such functions. If these functions are important to your current driving
situation, do not use the AUX input.

10 JL AUDIO CleanSw eep™ CL 441dsp

The “Creature Comfort Method”:

Being audio purists, we strongly recommend
that you use the CL441dsp’s Master Volume
Control for all volume adjustments. If placed
on the center console, it can be even more
convenient to use than the OEM control.

If you are unmoved by our recommendation
and still prefer to use the OEM head unit’s volume
knob or the steering wheel volume controls,
simply set the CL441dsp’s Master Volume
Control at a comfortable level and use the OEM
volume control(s) for routine adjustment. You
may experience some changes in the frequency
response at low and high volumes. These shifts
may or may not be acceptable, depending on your
vehicle and your listening tastes. You may also
experience an increase in system hiss at lower
volume levels.

To switch to AUX Input mode and to control
the level of the AUX Source (if one is connected),
you will need to use the CL441dsp’s Master
Volume Knob. The OEM volume controls will have
no effect on the AUX Source level.

CHANNEL STATUS CODES :

GREEN (steady):
OEM Input Engaged / EQ Successful & Active

This indicates that the CL441dsp has effectively
corrected the OEM response and is in OEM
Input Mode.

GREEN (flashing):
OEM Input Engaged / EQ Defeated

This indicates that the OEM Input Mode is
engaged and the CL441dsp’s equalizer has been
defeated by pressing the “EQ DEFEAT” button.
This mode allows you to compare the raw OEM
response to the corrected response and will
remain engaged for a maximum of five minutes (in
case you forget you pressed the “EQ DEFEAT”
button). To exit this mode manually, press the
“EQ DEFEAT” button again.

AMBER (steady):
AUX Input Engaged / EQ Defeated

This indicates that the AUX input signal is
being passed to the CL441dsp’s outputs without
any equalization.

RED/GREEN (alternating):
EQ Active, only partial correction was achieved.

This indicates that the CL441dsp corrected the
frequency response to the best of its abilities, but
failed to achieve a flat response. The output may
be usable, but merits investigation with a Real
Time Analyzer.

RED (steady):
Calibration Failed due to insufficient input signal,
previous settings have been restored for those
channels exhibiting this code.

This indicates that there was insufficient or non­existent signal present on the channels exhibiting
this code. If you only connected two channels of
input, the other two channels will show this code.
If this code appears on channels you attempted
to connect, you will need to verify that signal was
present at the CL441dsp’s OEM Inputs during
calibration and that this signal was analog audio.

RED (flashing):
Calibration Failed (input signal not full-range),
previous settings have been restored for those
channels exhibiting this code.

This indicates that the signals connected to
the channels exhibiting this code were not full­range and were not able to be corrected. You
will need to analyze the input signals with a Real
Time Analyzer and see if these can be summed
with other signals (using a summing device) before
connecting them to the CL441dsp’s inputs. You
may also choose to use only two channels if this
error code only exists on one channel pair.
