Configuração e instalação
A instalação correta é crucial para o desempenho e a segurança ideais. Siga estas etapas cuidadosamente.
Considerações sobre fiação
- Always use high-quality power and ground cables. For the JH15001, a minimum of 4-gauge power and ground wire is recommended.
- Install an in-line fuse holder within 18 inches of the vehicle's battery. The fuse rating should match the amplifier's requirements (typically 80-100A for this power level).
- Ensure all connections are clean, tight, and free from corrosion.
Conexões de energia
Figura 3: Traseira view of the MTX Audio JH15001 amplifier, detailing the Power Input (GND, REM, +12V) and Speaker Output terminals.
- Terra (GND): Connect the ground terminal to a clean, unpainted metal surface of the vehicle's chassis. The ground wire should be as short as possible, ideally less than 3 feet (1 meter).
- Remoto (REM): Connect the remote terminal to the remote turn-on output of your head unit. This wire signals the ampO amplificador deve ligar quando a unidade principal estiver ativa.
- + 12V: Connect the +12V terminal to the positive terminal of your vehicle's battery, via the in-line fuse holder.
Conexões de alto-falantes
The JH15001 is a monoblock amplifier, designed for a single subwoofer or multiple subwoofers wired to a single channel. Refer to Figure 3 for the speaker output terminals.
- Connect your subwoofer(s) to the "SPEAKER OUTPUT" terminals. Ensure correct polarity (+ to + and - to -).
- O amplifier is stable down to 1 Ohm. Ensure your subwoofer's impedance (or combined impedance of multiple subwoofers) matches the amplifier's capabilities for optimal performance and to prevent damage.
Conexões de entrada
Figura 4: Traseira view of the MTX Audio JH15001 amplifier, showing the Line Input (RCA) and Auto Turn On switch.
- Entrada de linha (RCA): Connect the RCA output from your head unit or signal processor to the "LINE INPUT" (L CH and R CH) on the ampmais vivo.
- Ativação automática: Este interruptor permite que o amplifier to turn on automatically by sensing a DC offset or audio signal on the input. Set to "REM" if using a dedicated remote wire, or "AUDIO" if using signal sensing.
- Nível de entrada: This switch adjusts the input sensitivity for either "PRE IN" (low-level RCA input) or "SPK IN" (high-level speaker input, if using a line output converter).
Botão de graves remoto
Connect the included remote bass knob to the "EBC" port on the amplifier (refer to Figure 4). This allows for convenient adjustment of the bass level from the driver's seat.
Instruções de operação
Após a instalação, você poderá ajustar o ampAjuste as configurações do amplificador para obter o melhor desempenho de áudio.
Ajuste de ganho
The "GAIN" knob (refer to Figure 1) matches the ampSensibilidade de entrada do amplificador em relação ao volume de saídatage of your head unit. This is not a volume control. To set the gain:
- Turn the gain knob all the way down (counter-clockwise).
- Ajuste o volume do seu aparelho de som para cerca de 75-80% do máximo.
- Gire lentamente o amplifier's gain knob clockwise until you hear slight distortion, then back it off slightly until the sound is clean.
Filtro passa-baixo (LPF)
The "LPF" knob (refer to Figure 1) controls the low-pass crossover frequency. This filter allows only frequencies below the set point to pass through to the subwoofer. Adjust this between 40Hz and 250Hz to blend the subwoofer's output with your main speakers.
Filtro Subsônico
The "SUBSONIC" knob (refer to Figure 1) controls a high-pass filter specifically for the subwoofer channel, preventing extremely low, inaudible frequencies from being played. These frequencies can waste amplifier power and potentially damage the subwoofer. Adjust this between 20Hz and 50Hz, typically set slightly below your LPF or subwoofer's resonant frequency.
Bass Boost
The "BASS BOOST" knob (refer to Figure 1) provides an adjustable boost (0-12dB) at 45Hz. Use this sparingly to enhance bass impact. Excessive bass boost can lead to distortion and potential damage to your subwoofer.
Ativação automática
As mentioned in the input connections, the "AUTO TURN ON" switch (Figure 4) allows the amplifier to power on without a dedicated remote wire. If your head unit does not have a remote output, set this to "AUDIO" to detect an audio signal, or "DC" (if available, though not explicitly labeled as DC on this model, it's implied by "AUDIO" vs "REM") to detect a DC offset on the speaker lines. For best results and reliability, using the "REM" setting with a remote wire from the head unit is recommended.
Manutenção
Your MTX Audio ampO amplificador requer manutenção mínima para garantir um desempenho duradouro.
- Limpeza: Limpe periodicamente o ampLimpe a parte externa do amplificador com um pano macio e seco. Não utilize produtos químicos agressivos ou abrasivos.
- Ventilação: Assegurar que o ampAs aletas de resfriamento do amplificador estão livres de poeira e detritos. Uma boa circulação de ar é essencial para evitar o superaquecimento.
- Conexões: Verifique periodicamente todas as conexões de energia, aterramento e alto-falantes para garantir que permaneçam firmes e seguras. Conexões soltas podem causar problemas de desempenho ou danos.
