6. ຄໍາແນະນໍາການດໍາເນີນງານ
ເມື່ອ ampເມື່ອຕິດຕັ້ງເຄື່ອງປັບອາກາດແລ້ວ, ໃຫ້ປະຕິບັດຕາມຄຳແນະນຳເຫຼົ່ານີ້ສຳລັບການດຳເນີນງານ:
- Gain Structure: Adjust the input gain on your source device and the amplifier's input sensitivity (via DIP switches) to achieve optimal signal-to-noise ratio without clipping. The SIGNAL indicator should illuminate consistently, and the CLIP/MUTE indicator should only flash momentarily during peak signals, if at all.
- ຕົວຊີ້ວັດການຕິດຕາມ: Regularly monitor the front panel indicators:
- CLIP/MUTE: If this light is constantly on, reduce the input level to prevent distortion and potential speaker damage.
- PROTECT/TEMP: If these lights illuminate, the amplifier is in protection mode or overheating. Turn off the unit, allow it to cool, and check for proper ventilation or speaker impedance issues.
- ໂໝດຂົວ: If operating in bridged mode, ensure the correct DIP switch settings are applied and that the speaker impedance is suitable for bridged operation (typically higher impedance than stereo mode).
- ປິດເຄື່ອງ: Always power down the amplifier after use by pressing the front panel power button.
