1.1 ഉൽപ്പന്നം കഴിഞ്ഞുview

The JL AUDIO LoC-22 is a 2-channel line output converter designed to integrate aftermarket amplifiers with factory car audio systems that lack RCA pre-amp outputs. It efficiently converts high-level (speaker-level) audio signals from a factory head unit or amplifier into low-level (RCA pre-amp level) signals, making them compatible with aftermarket amplifiers. This device is essential for upgrading your car's audio system while retaining the original head unit.

Before making any connections, ensure the vehicle's battery negative terminal is disconnected.

  1. പവർ കണക്ഷൻ: Connect the +12V terminal of the LoC-22 to a constant +12V power source (e.g., directly to the battery with an inline fuse, or a fused accessory wire). Connect the Ground terminal to a solid chassis ground point.
  2. സ്പീക്കർ-ലെവൽ ഇൻപുട്ടുകൾ: Connect the speaker output wires from your factory head unit or amplifier to the LoC-22's speaker input terminal block (L+, L-, R+, R-). Ensure correct polarity.
  3. ആർസിഎ ലൈൻ ഔട്ട്പുട്ടുകൾ: Connect standard RCA cables from the LoC-22's 'Line Outputs' to the RCA inputs of your aftermarket ampജീവൻ.

6. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

6.1 Turn-on Mode Selection

The LoC-22 offers two methods for automatic turn-on:

Set the 'Turn-on Mode' switch on the unit to the appropriate setting based on your vehicle's factory system.

6.2 Input Load Selection

The 'Input Load' switch allows you to optimize the LoC-22's input impedance for compatibility with various factory audio systems:

Set the 'Input Load' switch on the unit to the appropriate setting. Start with 'Normal' and switch to 'Low Z' if issues arise.

6.3 Adjusting Output Level

The 'Output Level' potentiometer allows you to match the output voltage of the LoC-22 to the input sensitivity of your aftermarket amplifier. This ensures optimal signal transfer and prevents clipping.

  1. Turn the 'Output Level' control fully counter-clockwise (minimum).
  2. Turn on your car's audio system and play a dynamic piece of music at about 75% of the head unit's maximum volume.
  3. Slowly turn the 'Output Level' control clockwise until the 'Clipping' LED on the LoC-22 just begins to flicker. Then, back off slightly until the LED remains off.
