4. ການຕິດຕັ້ງ ແລະການເຊື່ອມຕໍ່
Follow these steps to correctly set up your WWZMDiB XH-M543 ampຄະນະ lifier:
- ການປ້ອນຂໍ້ມູນພະລັງງານ: Connect a DC power supply ranging from 12V to 26V to the power input terminal. A 24V DC power supply is recommended for optimal performance. Ensure correct polarity (+ and -).
- ການປ້ອນຂໍ້ມູນສຽງ: Connect your audio source (e.g., MP3 player, mobile phone, computer) to the audio input terminal. The board includes a TLO74C amplifier chip for pre-amplification of the input signal.
- ລຳໂພງ Output: Connect your speakers to the audio output terminals. Pay close attention to the positive (+) and negative (-) poles for each channel. For best results, it is recommended to use professional stage speakers rated at more than 120W.
