3. Configuració i instal·lació

Una instal·lació correcta és crucial per a un rendiment i una seguretat òptims. Es recomana que la instal·lació la realitzi un professional qualificat.

3.1 Muntatge del Ampmés viu

Due to its compact dimensions, the A401 can be flexibly mounted in various locations within your vehicle. Ensure the mounting location provides adequate ventilation and is protected from moisture and excessive heat. Secure the amplifier firmly using appropriate hardware.

3.2 Connexions d'alimentació

Connect the power cables as follows:

• + 12V: Connect to the vehicle's positive battery terminal via a fuse (not included, ensure appropriate rating).
• COMANDAMENT: Connect to the remote turn-on output of your head unit. If using high-level inputs with Auto-Turn-On, this connection may not be necessary.
• TERRA: Connect to a clean, unpainted metal point on the vehicle chassis. Ensure a solid, low-resistance connection.

3.3 Connexions d'entrada d'àudio

The A401 supports both low-level (RCA) and high-level inputs.

• Entrada de baix nivell: Use RCA cables to connect to the RCA pre-outs of your head unit.
• Entrada d'alt nivell: For head units without RCA outputs, use the supplied high-level input harness to connect directly to the speaker outputs of your head unit. The amplifier features an Auto-Turn-On function for these inputs, detecting DC offset or audio signal to power on automatically.

3.4 Connexions de sortida d'altaveus

Connecteu els vostres altaveus al amplifier's output terminals. The A401 is a 4-channel amplifier, allowing for connection of four speakers or two speakers in bridged mode for higher power output to subwoofers.

4. Instruccions de funcionament

The AXTON A401 features various controls to fine-tune your audio system.

4.1 Gain (SENS) Adjustment

The SENS (Sensitivity) control adjusts the input gain of the amplifier. Set this control to match the output voltage of your head unit. Start with the SENS control at minimum and slowly increase it until the desired volume is achieved without distortion. Avoid setting the gain too high, as this can lead to distorted sound and potential damage to speakers.

4.2 Configuració del crossover (X-OVER)

The A401 includes integrated electronic crossovers for each channel pair (Front and Rear). These allow you to filter specific frequency ranges to your speakers.

• LPF (filtre de pas baix): Allows only frequencies below the set point to pass through. Useful for subwoofers.
• HPF (filtre de pas alt): Allows only frequencies above the set point to pass through. Useful for full-range or component speakers to prevent low frequencies that can cause distortion.
• COMPLET: Disables the crossover, allowing the full frequency range to pass.

The frequency knob (FREQ) allows continuous adjustment from 40 Hz to 400 Hz when LPF or HPF is selected.

4.3 Selecció del mode d'entrada

The INPUT MODE switch allows you to select between 2-channel and 4-channel input operation. This determines how the input signal is distributed to the amplifier's channels.

4.4 Auto-Turn-On Function

When using high-level inputs, the amplifier can automatically turn on by detecting a DC offset or audio signal from the factory head unit. This eliminates the need for a separate remote turn-on wire.

5. Manteniment

The AXTON A401 is designed for durability and requires minimal maintenance.

• Neteja: Netegeu periòdicament el amplifier's exterior with a soft, dry cloth to remove dust. Avoid using harsh chemicals or abrasive cleaners.
• Ventilació: Assegureu-vos que el amplifier's heat sink fins are not obstructed to allow for proper airflow and heat dissipation.
• Connexions: Regularly check all power and speaker connections to ensure they are secure and free from corrosion.

6. Solució De Problemes

If you encounter issues with your AXTON A401 amplifier, consulteu els següents problemes i solucions habituals:

• Sense alimentació (LED PWR apagat):
  • Check the main fuse on the +12V power line.
  • Verify all power connections (+12V, Remote, Ground) are secure and correctly wired.
  • If using Auto-Turn-On, ensure the head unit is providing a signal or DC offset.
• Protection Mode (PRT LED On):
  • This indicates a fault condition (e.g., short circuit, overheating, low voltagi).
  • Check speaker wiring for any shorts to ground or between positive and negative terminals.
  • Assegureu-vos una ventilació adequada al voltant amplificador per evitar el sobreescalfament.
  • Verifica el volum de la bateria del vehicletage és estable.
• Sense sortida de so:
  • Check all audio input connections (RCA or high-level) from the head unit.
  • Verify speaker connections are secure and correct.
  • Assegureu-vos que el volum de la unitat principal estigui alt i no silenciat.
  • Adjust the SENS (gain) control.
• So distorsionat:
  • Reduce the SENS (gain) control.
  • Check for proper crossover settings; incorrect settings can cause distortion.
  • Assegureu-vos que la impedància de l'altaveu coincideixi amb la ampespecificacions del lifier.
  • Check for damaged speakers or wiring.
