JL AUDIO CleanSweep ™ CL441dsp 11
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.
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.
