Manual Arahan Penukar Saluran Keluar 2-Saluran PAC LP72 LOC Pro

pengenalan

The PAC LP72 L.O.C. Pro 2-Channel Line-Out Converter is designed to integrate aftermarket amplifiers into vehicle audio systems. It facilitates the connection of an amplifier to either an OEM (Original Equipment Manufacturer) radio, retaining the factory amplified system, or to an aftermarket system that lacks RCA outputs. The LP72 also features an automatic remote turn-on circuit for amplifiers, eliminating the need for a separate remote wire connection from the head unit.

This manual provides detailed instructions for the proper installation and operation of your LP72 unit.

Persediaan dan Pemasangan

Pemasangan yang betul adalah penting untuk prestasi optimum. Adalah disyorkan agar pemasangan dilakukan oleh profesional yang berkelayakan.

Sambungan Pendawaian

1. Sambungan Kuasa: Connect the red wire to a switched 12V power source.
2. Sambungan Tanah: Connect the black wire to a solid chassis ground point.
3. Output Jauh: The blue wire provides the remote turn-on signal for your aftermarket amplifier. Connect this to the amplifier's remote input terminal.
4. High-Level Input (Speaker Wires): If connecting to speaker outputs from an OEM radio or amplifier, connect the vehicle's speaker wires to the corresponding input wires on the LP72 harness (e.g., Left Front +, Left Front -, Right Front +, Right Front -). Ensure correct polarity.
5. Output Aras Rendah (RCA): Connect the RCA outputs from the LP72 to the RCA inputs of your aftermarket amplebih hidup.

The LP72's differential inputs are designed to work effectively with various OEM systems, including those with premium audio setups like BOSE, minimizing noise and ensuring signal integrity.

Melekap

The compact design of the LP72 allows for flexible mounting options. Secure the unit using wire-ties or screws in a location that is dry, free from excessive heat, and away from potential interference sources. Ensure adequate ventilation.

Arahan Operasi

Dapatkan Pelarasan

The LP72 features precision stereo gain dials to match the output level of the converter to the input sensitivity of your aftermarket amplifier. This ensures optimal system performance and prevents distortion.

1. Start with the gain controls on the LP72 set to their minimum position.
2. Turn your vehicle's head unit volume to about 75% of its maximum level.
3. Slowly increase the gain controls on the LP72 until you hear a slight distortion, then back off slightly until the sound is clear.
4. Adjust the gain controls on your aftermarket amplifier according to its manufacturer's instructions, ensuring no distortion at desired listening levels.

Keuntungan yang betul staging is essential for achieving clear, powerful audio without introducing unwanted noise or clipping.

Menyelesaikan masalah

• Tiada Keluaran Bunyi:
  • Sahkan semua sambungan kuasa dan pembumian adalah kukuh.
  • Check that the remote turn-on wire is properly connected to the ampliifier dan bahawa amplifier is powering on.
  • Ensure speaker input wires are correctly connected to the LP72 and RCA outputs are connected to the amplebih hidup.
  • Confirm head unit volume is up and not muted.
• Bunyi Herot:
  • Reduce the gain settings on the LP72 and/or the amplebih hidup.
  • Ensure the head unit volume is not excessively high, causing distortion before the signal reaches the LP72.
• Engine Whine or Noise:
  • Ensure the ground connection for the LP72 and amplifier is solid and free from paint or corrosion.
  • Route power cables away from audio signal cables to prevent interference.
  • Check for loose connections in the audio path.
  • The LP72's differential inputs are designed to minimize noise; however, external factors can still introduce interference.
• AmpPengaktif Tidak Menghidupkan:
  • Verify the blue remote wire from the LP72 is connected to the ampinput jauh liifier.
  • Ensure the LP72 is receiving power and ground.
  • Confirm the head unit is on and producing an audio signal for the LP72 to detect and generate the remote signal.
