2฀JL฀AUDIO฀CleanSweep™฀CL441dsp

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.฀

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.

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.

฀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฀auxiliary฀

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฀level-

match฀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฀surface฀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฀insert฀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฀turn-

on฀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฀

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฀performance฀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฀CleanSweep™฀CL441dsp

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฀non-

existent฀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฀full-

range฀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.
