3. 설정 및 설치

3.1 외장재 권장 사항

The GTR84 subwoofer performs optimally in properly designed enclosures. For best results, consider the following recommendations:

• 포트형 박스: Approximately 0.96 cubic feet (9.6"H x 15"D x 10.8"W) tuned to 39.9Hz.
• 봉인된 상자: Approximately 0.5 cubic feet.

3.2 Wiring Configurations (Dual 4 Ohm)

The GTR84 features dual 4 Ohm voice coils, offering flexibility in wiring to match your amp앰프의 임피던스 요구 사항을 항상 확인하십시오. amp앰프는 선택된 임피던스에서 안정적입니다.

3.2.1 Series Wiring (8 Ohm Total)

보이스 코일 1의 양극 단자를 보이스 코일 2의 음극 단자에 연결하십시오. 그런 다음, 연결하십시오. amp앰프의 양극 출력을 보이스 코일 2의 양극 단자에 연결하고, amp앰프의 음극 출력을 보이스 코일 1의 음극 단자에 연결합니다. 이 구성은 8옴 부하를 생성합니다.

3.2.2 Parallel Wiring (2 Ohm Total)

Connect the positive terminals of both voice coils together. Connect the negative terminals of both voice coils together. Then, connect the amp증폭기의 양극 출력을 결합된 양극 단자에 연결하고, amp앰프의 음극 출력을 결합된 음극 단자에 연결합니다. 이 구성은 2옴 부하를 생성합니다.

3.3 장착

Ensure the mounting surface is rigid and free from obstructions. Use appropriate mounting hardware to secure the subwoofer firmly within the enclosure. Refer to the dimension diagram for precise cutout and mounting hole measurements.

4. 사용 설명서

4.1 Initial Power-Up and Break-in

After installation, gradually increase the volume during the first few hours of use. This 'break-in' period allows the subwoofer's suspension components to loosen and settle, leading to optimal performance. Avoid playing at maximum volume during this initial phase.

4.2 Amplifier 설정

올바르게 설정하기 amplifier's gain and crossover frequencies is crucial for sound quality and subwoofer longevity.

• 이득 설정: 설정하다 amp앰프 게인을 출력 볼륨에 맞추세요tag헤드 유닛의 게인을 너무 높게 설정하지 마십시오. 왜곡 및 손상이 발생할 수 있습니다.
• 저역 통과 필터(LPF): LPF를 설정하세요 amplifier to filter out frequencies above the subwoofer's intended range, typically between 80Hz and 120Hz.
• 아음속 필터: If available, set a subsonic filter to protect the subwoofer from playing frequencies below its resonant frequency (Fs), which is 39.9Hz for the GTR84. A setting around 30Hz is often appropriate.

5. 유지관리

To ensure the longevity and performance of your GTR84 subwoofer, follow these maintenance guidelines:

• 청소: Use a soft, dry cloth to gently wipe down the subwoofer cone and surround. Avoid using harsh chemicals or excessive moisture.
• 점검: Periodically inspect the subwoofer for any signs of damage, such as tears in the surround or cone, loose connections, or unusual wear.
• 환경 조건: Protect the subwoofer from extreme temperatures, direct sunlight, and moisture. Ensure adequate ventilation around the enclosure to prevent overheating.

6. 문제 해결

If you experience issues with your GTR84 subwoofer, refer to the following common troubleshooting steps:

• 소리 없음:
  • Check all wiring connections (power, ground, remote, signal, speaker).
  • 확인하다 amp앰프 전원이 켜져 있고 보호 모드가 아닙니다.
  • 헤드 유닛에서 오디오 신호가 출력되는지 확인하십시오.
• 왜곡된 소리:
  • 감소하다 amp앰프 게인 설정.
  • 크로스오버 설정이 올바른지 확인하십시오.
  • 서브우퍼 콘과 서라운드에 물리적 손상이 있는지 검사하십시오.
• 과열:
  • 주변에 적절한 환기가 되도록 하십시오. amp리퍼와 서브우퍼.
  • 확인하다 amplifier's impedance matches the subwoofer's wiring configuration.
  • 장시간 큰 소리로 재생하는 것을 줄이세요.
