Connection SLI 2.2 Speaker Level Interface User Manual

1. හැඳින්වීම

The Connection SLI 2.2 is a 2-channel speaker level interface designed to convert high-level speaker outputs from an OEM (Original Equipment Manufacturer) source or amplifier into a low-level RCA signal suitable for aftermarket amplifiers. This device ensures optimal audio quality and seamless integration with various car audio systems.

2 ප්රධාන ලක්ෂණ

• Excellent Audio Quality: Utilizes high-quality transformers and STOP NOISE technology for full bandwidth preservation and total rejection of electrical interference through galvanic separation.
• පහසු ස්ථාපනය: Features a robust, compact, and shielded aluminum chassis with a clear connection diagram and side-mounted connection panel.
• Single Connector Wiring: Labeled wiring terminated with a Molex connector and tear-proof plastic strip for secure and easy connections.
• Total OEM Integration (DSR): Double Step-Down Ratio (DSR) offers selectable 8:1 (High-Power) and 4:1 (Low-Power) conversion ratios via DIP switches for each input (front and rear), supporting outputs up to 35V RMS.
• Universal Speakers Simulator (USS): Simulates speaker load on all 4 input channels (front and rear) for compatibility with OEM sources that detect original speaker impedance.
• Automatic Remote Turn-On (ARTTM): Generates a 12V output for amplifier remote control, compatible with all OEM sources, including latest generation units.

4. පිහිටුවීම සහ ස්ථාපනය

ආරක්ෂාව පළමුව: Disconnect the vehicle's battery before beginning any electrical installation to prevent short circuits and damage to components.

1. Mounting the SLI 2.2:

   Choose a secure, dry location for mounting the SLI 2.2 unit, away from excessive heat or moisture. The robust aluminum chassis is designed for durability. Use appropriate fasteners (not included) to secure the unit.

2. Connecting Speaker Level Inputs:

   Identify the speaker output wires from your OEM head unit or amplifier. Connect these high-level outputs to the corresponding input wires on the SLI 2.2 wiring harness. Ensure correct polarity (positive to positive, negative to negative) for each channel.

3. Setting the Double Step-Down Ratio (DSR) DIP Switches:

   The SLI 2.2 features DIP switches to select the appropriate step-down ratio for each input channel independently. Refer to the diagram on the unit or the table below:

   DIP ස්විච් සැකසීම	පරිවර්තන අනුපාතය	යෙදුම
   OFF (Low-Power)	4:1	Traditional OEM sources (lower voltage outputs)
   ON (High-Power)	8:1	OEM amplifiers with high-voltage outputs (up to 35V RMS)

   Adjust the DIP switches according to the output voltage of your OEM source. Incorrect settings may result in distorted audio or insufficient signal to your aftermarket ampජීවිතාරක්ෂකයා.

4. Connecting RCA Outputs:

   Connect the RCA output cables from the SLI 2.2 to the RCA input jacks on your aftermarket amplifier. Ensure left and right channels are correctly matched.

5. Connecting Remote Turn-On (ARTTM):

   The SLI 2.2 provides an Automatic Remote Turn-On (ARTTM) output. Connect the remote output wire from the SLI 2.2 to the remote input terminal on your aftermarket amplifier. This will automatically turn on your amplifier when the OEM source is active.

6. බල සම්බන්ධතාවය:

   Connect the power and ground wires of the SLI 2.2 wiring harness to appropriate power sources in your vehicle. Typically, the positive wire connects to a switched 12V source (or constant 12V if preferred, but switched is recommended to prevent battery drain), and the negative wire connects to a solid chassis ground point.

5. මෙහෙයුම් මූලධර්ම

The Connection SLI 2.2 operates by taking the high-voltage speaker output from your vehicle's factory audio system and safely converting it into a low-voltage RCA signal. This process is critical for integrating aftermarket amplifiers, which typically require a low-level input signal.

• සංඥා පරිවර්තනය: High-quality transformers within the unit perform the voltage step-down, ensuring minimal signal degradation.
• ශබ්දය ප්රතික්ෂේප කිරීම: STOP NOISE technology and galvanic isolation prevent electrical interference from affecting the audio signal, resulting in a clean output.
• Speaker Load Simulation (USS): The Universal Speakers Simulator ensures that the OEM head unit detects a proper speaker load, preventing it from shutting down or altering its output due to the absence of connected speakers.
• Automatic Activation (ARTTM): The Automatic Remote Turn-On feature simplifies system operation by automatically activating the connected amplifier when the OEM audio system is turned on, eliminating the need for a separate remote wire from the head unit.

6. නඩත්තු කිරීම

The Connection SLI 2.2 is designed for maintenance-free operation. To ensure longevity and optimal performance:

• ඒකකය දූවිලි හා සුන්බුන් වලින් තොරව තබා ගන්න.
• Ensure all connections remain secure. Periodically check wiring for any signs of wear or corrosion.
• ඒකකය අධික උෂ්ණත්වයට හෝ තෙතමනයට නිරාවරණය කිරීමෙන් වළකින්න.
