- ຢ່າປະຕິບັດການ amplifier if it has been exposed to water or sustained physical damage.
- ຊອກຫາຄວາມຊ່ວຍເຫຼືອຈາກຜູ້ຊ່ຽວຊານຖ້າທ່ານບໍ່ແນ່ໃຈກ່ຽວກັບຂັ້ນຕອນການຕິດຕັ້ງໃດໆ.
ການຕິດຕັ້ງແລະການຕິດຕັ້ງ
ການຕິດຕັ້ງທີ່ຖືກຕ້ອງແມ່ນມີຄວາມ ສຳ ຄັນຫຼາຍຕໍ່ປະສິດທິພາບແລະຄວາມປອດໄພຂອງອຸປະກອນ amplifier. Refer to the diagrams below for connection details.
ການຕິດຕັ້ງ Ampມີຊີວິດຊີວາ
Choose a mounting location that is dry, well-ventilated, and secure. Avoid mounting on carpet or in enclosed spaces that restrict airflow. Ensure sufficient space around the amplifier ສໍາລັບການກະຈາຍຄວາມຮ້ອນ.

ການເຊື່ອມຕໍ່ພະລັງງານ
- +12V (ພະລັງງານ): Connect directly to the positive terminal of the vehicle's battery using a fuse holder within 18 inches of the battery.
- GND (ດິນ): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid connection.
- REM (ການເປີດທາງໄກ): ເຊື່ອມຕໍ່ກັບຜົນຜະລິດທາງໄກຂອງຫົວຫນ່ວຍຂອງທ່ານ. ສາຍນີ້ປ່ຽນເປັນ ampເປີດ ແລະ ປິດເຄື່ອງສຽງດ້ວຍສະເຕີລິໂອລົດຂອງທ່ານ.
ການເຊື່ອມຕໍ່ສຽງເຂົ້າ
- ຂາເຂົ້າ RCA (ລະດັບຕ່ຳ): Connect to the RCA pre-amp outputs of your head unit.
- ວັດສະດຸປ້ອນລະດັບສູງ: If your head unit does not have RCA outputs, use the high-level inputs by connecting them to your speaker wires.
ການເຊື່ອມຕໍ່ຂາອອກ
- ໂໝດສະເຕີລິໂອ (2 ຊ່ອງ): Connect one speaker to the left channel outputs (+ and -) and another speaker to the right channel outputs (+ and -).
- Bridged Mode (1-Channel Mono): For higher power output to a single subwoofer, bridge the amplifier. Connect the positive terminal of the speaker to the positive output of one channel and the negative terminal of the speaker to the negative output of the other channel (refer to specific bridging instructions on the amplifier or in a detailed wiring diagram). The LA978 offers 1200 Watts x 1 bridged output.
ຄໍາແນະນໍາການດໍາເນີນງານ

ການຄວບຄຸມລະດັບການປ້ອນຂໍ້ມູນຕົວປ່ຽນແປງ (ຮັບ).
ການຄວບຄຸມນີ້ກົງກັບ amplifier's input sensitivity to the output of your head unit. Start with the gain control at minimum, then slowly increase it until you hear distortion, then back it off slightly. Do not use the gain control as a volume knob.
ເຄືອຂ່າຍອີເລັກໂທຣນິກ Crossover ປ່ຽນແປງໄດ້ Hi/Lo
Use the crossover controls to filter frequencies. A ຕົວກອງຜ່ານຕໍ່າ (LPF) allows only low frequencies to pass, ideal for subwoofers. A ການກັ່ນຕອງຜ່ານສູງ (HPF) allows only high frequencies to pass, ideal for full-range speakers or tweeters. Adjust these settings to match your speakers' capabilities and desired sound.
ຕົວປ່ຽນ Bass Boost
This feature allows you to increase the bass output at a specific frequency. Use sparingly to avoid distortion and potential speaker damage. The amplifier also supports a ການເພີ່ມສຽງເບດໄລຍະໄກ for convenient adjustment from the driver's seat (remote sold separately or included depending on package).
ຕົວຊີ້ວັດ LED
- ເປີດໄຟ LED: illuminates ໃນເວລາທີ່ amplifier is receiving power and operating normally.
- LED ປ້ອງກັນ: illuminates ໃນເວລາທີ່ amplifier detects a fault (e.g., thermal overload, short circuit, low voltage). If this LED lights up, immediately turn off your audio system and troubleshoot the issue.
ບໍາລຸງຮັກສາ
- ທໍາຄວາມສະອາດ: ໃຊ້ຜ້າທີ່ອ່ອນໆ, ແຫ້ງເພື່ອເຮັດຄວາມສະອາດ ampພາຍນອກຂອງເຄື່ອງປັບອາກາດ. ຢ່າໃຊ້ສານເຄມີທີ່ຮຸນແຮງ ຫຼື ນໍ້າຢາທໍາຄວາມສະອາດທີ່ຂັດ.
- ການລະບາຍອາກາດ: ຮັບປະກັນວ່າ amplifier's cooling fins are free from dust and obstructions to maintain proper airflow and prevent overheating.
- ການເຊື່ອມຕໍ່: Periodically check all power, ground, and speaker connections to ensure they are secure and free from corrosion.
