Connection SLI 4.3 High To Low Level Conversion Interface For OEM-Integration

Seamless OEM Audio Integration with the SLI 4.3 Converter
Upgrade your car's sound system while preserving the integrity of your original equipment with the SLI 4.3, a high-quality high-to-low level conversion interface. Designed for seamless OEM integration, this device offers four inputs and four outputs with Double Step-Down Ratio (DSR), ensuring compatibility with both traditional and high-power OEM sources. Enjoy pristine audio thanks to superior transformers and STOP NOISE technology, which together deliver total rejection of electrical interference for crystal-clear sound.

Robust Design for Easy Installation
The SLI 4.3 stands out with its compact, shielded aluminum chassis that helps maintain signal clarity while making installation a breeze—even in tight spaces like the rear dashboard. All connections reside on one side for straightforward setup, and the connection diagram located on the bottom streamlines the process for installers of any skill level.

Reliable, User-Friendly Connection Features
Wiring comes pre-labeled and terminated with a durable Molex® connector and tear-proof plastic strip, ensuring both an effortless and long-lasting connection to your system. The SLI 4.3 incorporates advanced adaptation capabilities, including independent selection of high (8:1) and low (4:1) conversion ratios for each input, a Universal Speakers Simulator (USS) to replicate speaker load, and signal-triggered turn-on options for complete system compatibility. The integrated Automatic Remote Turn-On (ARTTM) delivers reliable remote amplifier activation across all mainstream and latest-generation OEM sources, providing a true plug-and-play solution for your next audio upgrade.

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.
