Product Details

JL Audio CleanSweep Signal Summing Interface, Model CLSSI

Until now, summing filtered OEM audio signals has involved using products intended for other applications in creative ways (typically involving lots of cables, y-adaptors and other complicated means). Here is a better way. The CleanSweep® CL-SSI is the industry’s first dedicated signal summing interface and is easily configured to merge 2-way or 3-way OEM signals prior to sending them into a CL441dsp for response correction. This makes it the perfect choice for integrating with “premium” OEM sound systems that do not present full-range audio signals.


  • 2-way or 3-way Summing Capability
    • In 2-way mode, the CL-SSI will sum the OEM subwoofer signal(s) to both front and rear OEM high-pass signals, creating front and rear, full-range stereo signals.
    • In 3-way mode, the CL-SSI will sum the OEM low-pass, bandpass and high-pass signals, creating a stereo pair of full-range signals.
  • Intuitive Level-Setting Indicators
    Allow the user to quickly balance signal levels without additional equipment. Each input section features a green LED optimum level indicator flanked by LED’s indicating “Too Low” or “Too High”. This allows for quick and accurate level matching via the Level Trim controls in a matter of seconds.
  • Defeatable Signal-Sensing Turn-On Circuit
    Allows the CL-SSI to turn on an entire aftermarket audio system when signal is sensed at its inputs.
  • Differential-Balanced Inputs
    Differential-Balanced Inputs ensure noise immunity and compatibility with a wide range of OEM source units and amplifiers, including those with load-detecting startup logic. Input Range Switching allows any combination of line-level or speaker-level signals to be used as inputs, permitting accurate level setting. Speaker-level input position is compatible with OEM power chips that use load-detecting startup logic.
