5. Configuració i instal·lació
Una instal·lació correcta és crucial per a un rendiment i una seguretat òptims. Si no esteu segurs de cap dels passos a seguir, consulteu un instal·lador professional.
5.1 Muntatge del Ampmés viu
Choose a mounting location that is dry, well-ventilated, and secure. Ensure sufficient space around the amplifier for air circulation. Use the provided mounting hardware to firmly secure the amplifier to a solid surface in the vehicle.

5.2 Connexions de cablejat
Refer to the diagram below for connection points. Always use appropriate gauge wiring.
Imatge 5.2: acabatview of amplifier connections and controls.
- Connexió d'alimentació (+24 V): Connect a fused 24V power cable directly from the vehicle's battery. Ensure the fuse is located close to the battery.
- Connexió a terra (GND): Connect a short, heavy-gauge cable from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle chassis.
- Engegada remota (REM): If using low-level inputs, connect this to the remote output of your head unit. If using high-level inputs with Auto-Turn-On, this connection may not be necessary.
- Sortides dels altaveus: Connect your speakers to the FRONT and REAR output terminals. Observe correct polarity (+/-). For bridged mode, refer to the specific bridging instructions.
- Connexions d'entrada:
- Entrada d'alt nivell: Connect the speaker outputs from your head unit directly to the amplifier's high-level input terminals. This is ideal for factory radios without RCA outputs.
- Entrada de baix nivell (RCA): If your head unit has RCA pre-outs, connect them to the ampels conectors d'entrada RCA del lificador.
5.3 Auto-Turn-On Function
The AT401 features an Auto-Turn-On function for high-level inputs. This allows the amplifier to turn on automatically when it detects an audio signal from the head unit, eliminating the need for a separate remote turn-on wire. Ensure the switch is set to the appropriate mode (DC or VOX) for this function.

6. Instruccions de funcionament
Once installed, the AT401 amplifier offers various adjustments to fine-tune your audio system.
6.1 Gain (SENS) Adjustment
The gain control (SENS) matches the amplifier's input sensitivity to the output level of your head unit. Start with the gain set to minimum. Gradually increase the head unit volume until distortion is heard, then back off slightly. Then, slowly increase the amplifier's gain until the desired volume is achieved without distortion.
6.2 Crossover (X-OVER) Settings
The AT401 features integrated 12 dB/octave electronic crossovers, adjustable from 40 to 400 Hz. These allow you to filter specific frequency ranges to your speakers.
Image 6.1: Adjustment options for crossovers and input sensitivity.
- HPF (filtre de pas alt): Permet freqüències a dalt the set point to pass through. Use for full-range speakers to prevent low bass distortion.
- LPF (filtre de pas baix): Permet freqüències a continuació the set point to pass through. Use for subwoofers.
- COMPLET: Disables the crossover, allowing all frequencies to pass.
Adjust the FREQ knob to select the desired crossover frequency for each channel pair (FRONT/REAR).
7. Manteniment
- Mantenir el ampNetegeu el purificador amb un drap suau i sec. No utilitzeu productes químics agressius ni netejadors abrasius.
- Ensure that the heat sink fins are free from dust and debris to maintain proper cooling.
- Comproveu regularment totes les connexions del cablejat per verificar si estan ben ajustades i si hi ha corrosió.
- Eviteu col·locar objectes a sobre amplifier that could obstruct airflow.
8. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Sense alimentació/Sense so | Blown fuse, loose power/ground connection, no remote signal, incorrect Auto-Turn-On setting. | Check fuse, verify power/ground connections, ensure remote wire is connected (if applicable), check Auto-Turn-On switch. |
| So distorsionat | Gain set too high, incorrect crossover settings, damaged speaker. | Reduce gain, adjust crossover settings, check speaker condition. |
| No hi ha so d'un canal | Loose speaker wire, faulty RCA/high-level input, damaged speaker. | Check speaker connections, verify input signal, test speaker. |
| AmpLa vida s'escalfa | Insufficient ventilation, low impedance load, prolonged high output. | Ensure proper airflow, check speaker impedance, reduce volume or gain. |
