Figura 5.1: Panell posterior 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): Connecteu-lo a una superfície metàl·lica neta i sense pintar del xassís del vehicle.
• REM (remot): Connecteu-lo a la sortida d'encesa remota de la unitat principal o a una font commutada de 24 V.
• +24V (Alimentació): 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 D'ALT NIVELL: For connecting to your head unit's speaker outputs if RCA pre-outs are not available.

5.3. Terminals de sortida

• OUTPUT (RCA): Line output for connecting to another amplificador en una multi-ampConfiguració del lifier.
• SORTIDA DE L'ALTAVEU: Connect your subwoofer(s) to these terminals. Observe correct polarity.

5.4. Control Knobs and Switches

• LEVEL INPUT (MIN/MAX): Ajusta la sensibilitat d'entrada perquè coincideixi amb la sortida de la unitat principal.
• SUB SONIC (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.
• BASS BOOST (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 el fitxer 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.
  • DESACTIVAT: Disables auto turn-on; requires REM connection.

6. Configuració i instal·lació

Una instal·lació correcta és crucial per al rendiment i la seguretat del vostre amplificador. Segueix aquests passos amb atenció.

6.1. Muntatge del Ampmés viu

• Trieu un lloc sec i ben ventilat, allunyat de la llum solar directa i de fonts de calor.
• Ensure there is sufficient space around the amplifier for airflow, especially around the cooling fins.
• Feu servir els cargols de muntatge proporcionats per fixar el amplifier firmly to a solid surface in your vehicle.

6.2. Power Wiring (24V System)

1. Desconnecta la bateria: Before making any power connections, disconnect the negative terminal of your vehicle's 24V battery.
2. Cable d'alimentació (+24V): 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 amplifier's "INPUT" RCA jacks.
• Entrada d'alt nivell: 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. Connexió de sortida d'altaveus

• 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. Engegada inicial

• Comproveu dues vegades que totes les connexions siguin correctes i segures.
• Torneu a connectar la bateria del vehicle.
• Engegueu la unitat principal. El amplifier should power on (indicated by a power LED).

7. Instruccions d'ús i ajustos

Once installed, fine-tune the ampConfiguració del lifter per a una qualitat de so òptima.

7.1. Gain (Level Input) Adjustment

• Ajusteu el volum de la unitat principal al 75% aproximadament del seu màxim.
• Interpretar una peça musical dinàmica.
• Augmenta lentament el amplifier's "LEVEL INPUT" gain control until you hear distortion, then back it off slightly. This matches the ampla sensibilitat d'entrada del lificador a la sortida de la unitat principal.

7.2. Crossover Settings (Subsonic & Low Pass)

• PAS BAIX (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. Augment dels baixos

• 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. Canvi 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. Remote Bass Control

• 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.
