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.

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-sw12V.  In this mode,  the 
CL441dsp will only wake up and turn on the rest 
of the system when it 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 
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 conven12 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-sw12V to 
prevent accidental battery drainage. If you decide 
to ignore the foregoing and use a manual switch 
fed by co12V, be aware that forgetting to 
shut the system off will result in battery drainage.
