PRODUCT OVERVIEW
The CleanSweep® CL-SSI is a dedicated signal
summing interface designed specifically for use
with the JL Audio CleanSweep® CL441dsp OEM
interface processor. Use of the CL-SSI with other
equipment is not supported by JL Audio.
This product performs the following functions:
1) The CL-SSI sums 2-way or 3-way stereo OEM
signals to full-range and outputs the summed
signals to a CL441dsp for response correction.
2) The CL-SSI is designed to accept virtually any
analog audio signal, from low-voltage line-level to
high-power, amplified speaker-level, via its three
input sections. Input Range Switching allows any
combination of line-level and speaker level signals
to be used as inputs. When switched to speaker
level input mode, the CL-SSI’s audio inputs are
compatible with OEM head units and amplifiers
that employ load-sensing startup logic.
3) “
Level Trim
” potentiometers on the top of
the CL-SSI allow for quick and accurate level-
matching of signals. Each input features a green
LED optimum level indicator flanked by LED’s
indicating “
Too Low
” or “
Too High
.” In most
cases, no additional equipment is necessary for
level matching the inputs.
4) Differential-Balanced Input architecture ensures
noise immunity and compatiblity with most
analog output OEM source units or amplifiers.
5) The CL-SSI can be set up in signal-sensing
mode, powering up and providing a 12-volt
turn-on signal for the CL441dsp whenever
signal is detected at its inputs. It can also be
activated by a conventional 12-volt trigger, in the
rare event that the OEM system provides one.
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 not certified or approved
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.
The CL-SSI should be mounted as close to the
CL441dsp as possible. The harness supplied for
connecting the CL-SSI’s outputs to the inputs of
the CL441dsp is 3 feet (91 cm) long.
Safety Considerations:
Your CleanSweep® CL-SSI 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® CL-SSI 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 that 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.
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.).
SERIAL NUMBER
In the event that your CleanSweep® CL-SSI
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.
