Тохиргоо ба суурилуулалт

Proper installation is crucial for optimal performance and safety. It is recommended to have this ampмэргэшсэн мэргэжилтэн суурилуулсан өргөгч.

1. суурилуулах Ampнастан

Choose a mounting location that is dry, well-ventilated, and protected from direct sunlight or excessive heat. Ensure sufficient space around the amplifier for air circulation. Use the provided mounting hardware to secure the ampөргөгчийг чангална.

2. Утасны холболт

Цахилгааны холболт хийхээс өмнө машины зайг салгасан эсэхийг шалгаарай.

• Цахилгаан холболт (+12V): Connect a suitable gauge power cable from the vehicle's positive battery terminal to the +12V terminal on the amplifier. An in-line fuse (not supplied) should be installed within 18 inches (45 cm) of the battery.
• Газрын холболт (GND): GND терминалаас богино, өндөр калибрын газардуулгын кабелийг холбоно уу. amplifier to a clean, unpainted metal surface on the vehicle's chassis.
• Алсын удирдлагатай асаалт (REM): Толгойн төхөөрөмжийн алсын гаралтаас алсаас асаах утсыг REM терминал руу холбоно уу amplifier. If your head unit does not have a remote output, the amplifier features an auto-sense turn-on mode (DC offset or Audio Sense) which can be selected.
• Чанга яригчийн холболтууд: чанга яригчаа холбоно уу amplifier's speaker output terminals. Observe correct polarity (+ to + and - to -). The amplifier supports 4-channel stereo or 2-channel bridged configurations.
• Оролтын холболтууд (RCA эсвэл Өндөр түвшний): Толгой хэсгийнхээ RCA гаралтыг холбоно уу amplifier's RCA input jacks. If your head unit lacks RCA outputs, use the supplied high-level input adapters to connect to your head unit's speaker outputs.

• Input Level (HI/LO): Selects between high-level (speaker-level) or low-level (RCA) input signals.
• Gain Control (MIN/MAX): Оролтын мэдрэмжийг тохируулна amplifier to match the output of your head unit. Start with minimum gain and slowly increase until desired volume is achieved without distortion.
• Crossover (X-OVER - HPF/LPF/FULL): Selects the type of filter for the output.
  • HPF (Өндөр нэвтрүүлэх шүүлтүүр): Allows frequencies above the set point to pass through, ideal for full-range speakers.
  • LPF (Бага нэвтрүүлэх шүүлтүүр): Allows frequencies below the set point to pass through, ideal for subwoofers.
  • БҮРЭН: Allows all frequencies to pass through, bypassing the crossover.
• Давтамж (FREQ): Adjusts the cutoff frequency for the HPF or LPF, typically ranging from 32Hz to 320Hz.
• Bass Boost (0dB/12dB): Provides an adjustable bass boost at 45Hz to enhance low-frequency output.
• Phase (0°/180°): Adjusts the phase of the output signal, useful for optimizing bass response with subwoofers.
• Turn-On Mode (DC/REM): Selects how the ampөргөгч асаалттай.
  • DC: Detects a DC offset on the high-level inputs to turn on the ampнастан.
  • REM: Uses a dedicated remote turn-on wire from the head unit.

Засвар үйлчилгээ

To ensure long-lasting performance from your JBL CLUB-704 amplifier, эдгээр энгийн засвар үйлчилгээний удирдамжийг дагана уу:

• Цэвэрлэгээ: Тогтмол арчиж арчих amplifier's exterior with a soft, dry cloth to remove dust and dirt. Avoid using harsh chemicals or abrasive cleaners.
• Агааржуулалт: гэдгийг баталгаажуулах amplifier's cooling fins are free from obstructions to allow proper heat dissipation.
• Холболтууд: Бүх утас холболтыг найдвартай, зэврэлтээс ангид байлгахын тулд үе үе шалгана уу. Сул холболт нь гүйцэтгэл муу эсвэл эвдрэлд хүргэдэг.
• Гал хамгаалагч солих: If a fuse blows, replace it only with a fuse of the same type and rating (30A). Using an incorrect fuse can damage the ampөргөгч асаах эсвэл гал гаргах.

Алдааг олж засварлах

Хэрэв танд асуудал тулгарвал amplifier, refer to the following common troubleshooting steps before contacting support:
