Connection SLI 2.3 High To Low Level Conversion Interface For OEM-Integration - SLI2.3

Connection SLI 2.3 High To Low Level Conversion Interface For OEM-Integration

Seamless OEM Audio Integration with the Connection SLI 2.3 Interface
Upgrade your vehicle’s audio system while preserving original sound quality with the Connection SLI 2.3 OEM integration interface. Engineered to bridge the gap between OEM head units and aftermarket amplifiers, this high to low-level converter ensures you get flawless signal transmission every time. Its 4-input, 2-output design is equipped with DSR (Double Step-Down Ratio), offering both High-Power and Low-Power conversion settings for fully customizable sound integration.

Superior Sound Clarity & Noise-Free Performance
The Connection SLI 2.3 is designed with high-quality transformers and STOP NOISE technology, delivering a pure, full-bandwidth signal and completely rejecting electrical noise. Galvanic separation between your source and amplifier means no hum or distortion—just crystal-clear audio.

Effortless & Robust Installation
Designed for convenience, this compact, shielded aluminum interface is simple to install even in tight vehicle spaces. The included Molex connector, paired with a durable, tear-proof plastic strip, ensures a secure and lasting connection. Clear labeling and integrated diagrams remove guesswork, so your installation process is stress-free.

Advanced Compatibility for Any Vehicle
Whether you are integrating with standard OEM sources or high-output factory amplifiers, the SLI 2.3 adapts effortlessly. Independent DIP switch adjustment per channel allows precise matching, while the unique USS (Universal Speakers Simulator) technology ensures compatibility with sources that require true speaker loads for operation. Additional features like signal turn-on and the ARTTM (Automatic Remote Turn-On) make this solution ready for even the latest vehicle audio systems.

Features

• Excellent Audio Quality
  Conversion achieved thanks to high-quality transformers that preserve the entire bandwidth and to the STOP NOISE technology offering total rejection of electrical interference as transformers provide a galvanic separation between source and amplifier.
• Easy to Install
  Robust and compact shielded aluminium chassis with connection diagram on the bottom and connection panel on one side that facilitates installation even in the rear dashboard.
• Single Connector
  Wiring labelled and terminated with Molex* connector featuring a tear-proof plastic strip, for a long-lasting and easy connection.
• Total OEM Integration
  • DSR (Double Step-Down Ratio)
    High-Power (8:1) and Low-Power (4:1) step down conversion ratio selectable via DIP switch independently for each input, front and rear, for a correct interface with both traditional OEM sources (Low-Power) or OEM amplifiers featuring high-voltage outputs (High-Power) up to 35V RMS.
  • USS (Universal Speakers Simulator)
    It simulates the load of the speakers on the 4 input channels (Front and Rear), for a complete compatibility of the interface with the OEM sources that detect the original speaker load (impedance) connected to their outputs.
  • Art^TM (Automatic Remote Turn-On)**
    Function compatible with all OEM sources, including the latest generation ones, which creates a 12 V output for the remote control of the amplifier when the SLI is powered.
