Familiarizarse co amplifier's layout and connection terminals before proceeding with installation.

Figura 5.1: Panel traseiro view of the ESX QL750.1 amplifier, highlighting power input, signal inputs (RCA and high-level), output, and various control knobs.

5.1. Power Input Terminals

• GND (terra): Connect to a clean, unpainted metal surface of the vehicle chassis.
• REM (Remoto): Conéctese á saída de acendido remoto da unidade principal ou a unha fonte conmutada de 24 V.
• +24V (Potencia): Connect directly to the positive terminal of the vehicle's 24V battery via an appropriate fuse holder.

5.2. Signal Input Terminals

• ENTRADA (RCA): Low-level RCA inputs for connecting to your head unit's RCA pre-outs.
• ENTRADA DE ALTO NIVEL: For connecting to your head unit's speaker outputs if RCA pre-outs are not available.

5.3. Terminais de saída

• OUTPUT (RCA): Line output for connecting to another amplifier nun multi-ampconfiguración do lifier.
• SAÍDA DE ALTAVOCES: Connect your subwoofer(s) to these terminals. Observe correct polarity.

5.4. Control Knobs and Switches

• LEVEL INPUT (MIN/MAX): Axusta a sensibilidade de entrada para que coincida coa saída da unidade principal.
• SUBSONICO (10Hz-40Hz): Filters out ultra-low frequencies below the audible range, protecting your subwoofer.
• LOW PASS (40Hz-150Hz): Sets the upper frequency limit for the subwoofer.
• REFORZO DE GRAVES (0dB-18dB): Increases bass output at 40Hz. Use sparingly to avoid distortion.
• PHASE SHIFT (0°-180°): Adjusts the phase of the subwoofer output to match other speakers in the system.
• AUTO TURN-ON (DC/VOX/OFF): Selecciona o amplifier's turn-on method when using high-level input.
  • DC: Detects DC offset from the head unit's speaker output.
  • VOX: Detects audio signal from the head unit's speaker output.
  • OFF: Disables auto turn-on; requires REM connection.

6. Configuración e instalación

Unha instalación axeitada é fundamental para o rendemento e a seguridade do seu amplificador. Siga estes pasos con atención.

6.1. Montaxe do Ampmáis vivo

• Escolle un lugar seco e ben ventilado, lonxe da luz solar directa e de fontes de calor.
• Asegúrate de que haxa espazo suficiente arredor do amplifier for airflow, especially around the cooling fins.
• Use os parafusos de montaxe fornecidos para fixar o ampo lifter firmemente a unha superficie sólida do seu vehículo.

6.2. Power Wiring (24V System)

1. Desconectar batería: Before making any power connections, disconnect the negative terminal of your vehicle's 24V battery.
2. Cable de alimentación (+24 V): Run a heavy-gauge power cable (e.g., 8 AWG or thicker, depending on cable length and power requirements) from the positive terminal of the 24V battery to the amplifier's "+24V" terminal. Install an appropriate fuse holder (e.g., 40A-60A, refer to amplifier specifications for exact rating) within 18 inches (45 cm) of the battery.
3. Cable de terra (GND): Run a heavy-gauge ground cable (same gauge as power cable) from the amplifier's "GND" terminal to a clean, unpainted metal part of the vehicle chassis. Ensure a good electrical connection.
4. Remote Turn-On Cable (REM): Run a smaller gauge wire (e.g., 18 AWG) from your head unit's remote turn-on output (usually blue/white wire) to the amplifier's "REM" terminal. If using high-level input with auto turn-on, this connection may not be necessary.

6.3. Signal Input Connection

• Entrada RCA: Connect RCA cables from your head unit's subwoofer pre-out (or full-range pre-out if no dedicated sub-out) to the ampas tomas RCA "INPUT" do amplificador.
• Entrada de alto nivel: If your head unit does not have RCA outputs, connect the speaker wires from your head unit to the amplifier's "HIGH LEVEL INPUT" connector. Ensure correct polarity. Set the "AUTO TURN-ON" switch to "DC" or "VOX" as appropriate.

6.4. Conexión de saída do altofalante

• Connect your subwoofer(s) to the "SPEAKER OUTPUT" terminals. Ensure correct polarity (+ to + and - to -).
• Verify the impedance of your subwoofer(s) to ensure it is within the amplifier's supported range (e.g., 1 Ohm stable).

6.5. Acendamento inicial

• Comprobe dúas veces a corrección e a seguridade de todas as conexións.
• Volva conectar a batería do vehículo.
• Acenda a unidade principal. O amplifier should power on (indicated by a power LED).

7. Operating Instructions and Adjustments

Once installed, fine-tune the ampaxustes do liferer para unha calidade de son óptima.

7.1. Gain (Level Input) Adjustment

• Set your head unit's volume to about 75% of its maximum.
• Play a dynamic piece of music.
• Aumentar lentamente o amplifier's "LEVEL INPUT" gain control until you hear distortion, then back it off slightly. This matches the ampa sensibilidade de entrada do adaptador á saída da unidade principal.

7.2. Crossover Settings (Subsonic & Low Pass)

• PASO BAIXO (LPF): Adjust this control to set the upper frequency limit for your subwoofer. A common starting point is 80-100 Hz, but this depends on your subwoofer and other speakers.
• SUB SONIC: Set this filter just below the lowest frequency your subwoofer can safely reproduce, or just below the tuning frequency of your ported enclosure. This protects the subwoofer from over-excursion. A common setting is 20-30 Hz.

7.3. Reforzo de graves

• The "BASS BOOST" control provides an increase in bass output at 40 Hz. Use this feature cautiously. Excessive bass boost can lead to distortion and potential damage to your subwoofer. Start at 0dB and increase gradually if desired.

7.4. Cambio de fase

• The "PHASE SHIFT" control (0°-180°) helps to align the subwoofer's output with the rest of your vehicle's speakers. Experiment with this setting while listening from your normal seating position. The correct setting will result in the most impactful and seamless bass response.

7.5. Control remoto de graves

• Connect the provided remote bass control unit to the amplifier. This allows for convenient adjustment of the subwoofer's output level from the driver's seat.
