3.4 Control Panel Settings

The front panel features controls for fine-tuning the amplifier's audio output:

• Input (CH1/CH2, CH3/CH4): ເຊື່ອມຕໍ່ສາຍ RCA ຈາກຫົວຫນ່ວຍຂອງທ່ານກ່ອນ.amp outputs to these inputs.
• Gain (CH1&2, CH3&4): ປັບຄວາມອ່ອນໄຫວຂອງວັດສະດຸປ້ອນ amplifier to match the output level of your head unit. Start with the gain at minimum and slowly increase until desired volume is achieved without distortion.
• Filter (HPF/FULL/LPF): Selects the crossover mode for the respective channels.
  • HPF (High Pass Filter): Allows frequencies above the set point to pass, blocking lower frequencies. Useful for full-range speakers.
  • LPF (ຕົວກອງຕ່ຳ): Allows frequencies below the set point to pass, blocking higher frequencies. Useful for subwoofers.
  • ເຕັມ: Allows all frequencies to pass without filtering.
• HPF/LPF Frequency Controls: Adjusts the cutoff frequency for the selected HPF or LPF.
• Boass Boost: Provides an adjustable bass enhancement at a specific frequency. Use sparingly to avoid distortion.

4. ຄໍາແນະນໍາການດໍາເນີນງານ

Once all connections are made and verified, you can power on your audio system. The amplifier will turn on automatically with your head unit via the remote wire.
