Features

Overview: The JL Audio CleanSweep CL441dsp OEM Audio Interface with Automatic Digital EQ is a DSP-based solution that permits almost any factory-installed audio system to serve as the source for a high-performance aftermarket sound system while also providing input for an additional source of your choice.

OEM Integration: The CL441dsp provides you with the following OEM integration features.

• Simple Installation: CleanSweep connects to your factory-installed system as if it were a speaker so the possibility of creating faults or diagnostic issues when the vehicle is serviced is virtually eliminated. CleanSweep's installation is fully reversible because there is no permanent modification of the factory system, and because CleanSweep is not a vehicle specific interface, it can be easily integrated into your next vehicle.
• Existing Factory Component Compatibility: CleanSweep allows you to retain your car's interior cosmetics and the full functionality of factory-installed vehicle functions, including navigation, OnStar, steering wheel controls, climate controls, etc. You can also use CleanSweep's master volume knob/source selector switch instead of the factory volume control.
• Auxiliary Source: With the CL441dsp, you gain the ability to add an aftermarket source of your choice (iPod, satellite radio tuner, DVD player, etc.) via direct line input, as opposed to inferior sounding FM-modulator approaches. Since these signals are free of equalization, CleanSweep will pass them without applying any correction. The master volume control knob, when pressed, selects between the factory source and the additional source unit. You can add more than one device with the addition of the optional source selector switch (136CLSES, sold separately).

Automatic Digital EQ: The CleanSweep OEM Interface with Automatic Digital EQ is a sophisticated digital audio processor that performs the following functions.

• Audio Signal Compatibility: CleanSweep 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, CleanSweep then converts the two or four connected analog signals to digital audio with 24 bit effective resolution.
• 32-Bit SHARC DSP Processor: CleanSweep applies the power of its state-of-the-art, 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, you simply load the supplied CleanSweep calibration CD into the factory-installed CD player, set its volume control between 1/2 and 3/4 volume, play the designated calibration track and then press the "Calibrate" button on the top of the CleanSweep processor. Approximately 20 seconds later, the CleanSweep is finished analyzing and equalizing the factory-installed source's response and stores the corrections in non-volatile flash memory.
• Analog-to-Digital-to-Analog Conversion: CleanSweep then converts the digitally corrected signals back to analog audio and sends them out to your aftermarket amplifiers through two pairs of low-distortion, 8 volt (RMS) line-level outputs.
• Master Volume Control: CleanSweep includes an intuitive rotary user interface (a knob with stops at both ends) to control the master system volume at the outputs of the processor unit for both the OEM (factory) and auxiliary sources. 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 knob also selects between the OEM and Auxiliary source. A dash-mountable status LED changes color to indicate OEM or AUX input modes. These controls can be easily mounted within reach of your driver's seat. The unit features either a black or silver volume control knob to choose from to match your vehicle's interior.
• Turn-On Control: CleanSweep can be deployed in signal-sensing mode, powering up and providing a 12-volt turn-on signal for your aftermarket equipment whenever signal is detected. It can also be activated by a conventional 12-volt trigger, if your OEM system provides one.

CL-LSA Loading Sensing Adapter: Included with the CleanSweep OEM Audio Interface is JL Audio's CL-LSA Load-Sensing Adapter. The JL Audio CL-LSA Load-Sensing Adapter is designed to present an appropriate impedance load to OEM headunit or amplifier outputs that employ "load-sensing startup protection" when used with JL Audio's CL441dsp CleanSweep OEM Audio Interface. When an OEM amplifier or headunit employs this type of protection, it checks the impedance of the connected load when the unit is powered up (expecting a speaker) and mutes its amplifier outputs if a load outside of a predicted range is detected. The CL441dsp's input impedance is outside of the range expected by some of these types of systems and can cause the OEM headunit or amplifier to mute. When the CL-LSA is inserted inline with the CleanSweep OEM Audio Interface's inputs, it presents a safe and appropriate load to your OEM component and corrects the muting behavior.

Connections/Controls/Indicators

Left Side Of Interface Module:

• Power Connector: 4-pin connector used to connect the supplied Power Connector harness which supplies Constant +12V, Switched +12V, Remote Turn-On +12V and Chassis Ground. This Constant and Switched leads are hardwired into your vehicle's electrical system while the Ground lead is grounded to the chassis of your vehicle. The Remote Turn-On lead connects to your aftermarket amplifier.
• Front And Rear Outputs: Four RCA-type jacks provide four-channels of analog audio output to feed your aftermarket car audio system using RCA cables (not provided).

Right Side Of Interface Module:

• OEM Input Connector: The CL441dsp accepts up to four channels of input from your OEM audio source via this 8-pin differential balanced plug using the supplied OEM Input harness. OEM audio signals connect to this connector must be close to full-range (20-20kHz). Otherwise, you will need to connect the optional CL-SS1 (sold separately) to sum multiple filtered OEM signals to full-range.
• Control Connector: The module features a 6-pin port used to connect the supplied wired remote volume control knob which allows you to control the system's volume as well as select between your vehicle's OEM inputs and the module auxiliary input.
• AUX Input: The unit features a set of left/right RCA jacks for connecting an external audio source to your factory audio system via RCA cables (not supplied).
• Signal Sense Switch: With this switch in the "On" position, it allows the CL441dsp to act as a turn-on and turn-off controller fro your aftermarket components in your system. You can also turn this feature "Off".

Top Panel Of Interface Module:

• Aux Input Level Trim Controls: The interface is equipped with a pair of level trim potentiometers that will permit you to level-match the AUX source to the OEM level of your vehicle's audio system.
• Calibrate Button: This button activates the calibration process of the CleanSweep Interface once you have installed the unit,  inserted the supplied Calibration Disc into your factory CD player and set the appropriate volume level and audio settings on your factory headunit.
• EQ Defeat Button: This button defeats the unit's calibration settings to allow you to listen to the difference in your factory system with and without the digital audio processing of the CleanSweep.
• Channel Status Indicators: The interface module features six LEDs along the top panel which indicate the status and operation of the CleanSweep unit.
