1. Collegamento elettrico: Connect the power plug to the amplifier. Ensure proper polarity (+12V, GND, Remote). Use appropriate gauge wiring for power and ground.
2. Collegamenti degli altoparlanti: Use the provided speaker connectors to connect your speakers to the amplifier's output terminals (CH1-CH4). Observe correct polarity.
3. Ingresso audio:
   • Input di alto livello: If your head unit does not have RCA outputs, use the high-level input cables provided. Connect them to the speaker outputs of your head unit.
   • Low-Level (RCA) Input: Collegare i cavi RCA dall'uscita pre-out dell'unità principale al amplifier's RCA input jacks (CH1/2, CH3/4).
4. Telecomando: Connect the level remote control if desired for convenient volume adjustment.

4. Funzionamento e regolazioni

The ETON MA 4 offers various controls to fine-tune your audio system. These controls are located under the removable top plate.

4.1 Accensione iniziale

1. Dopo aver effettuato tutti i collegamenti, ricollegare la batteria del veicolo.
2. Accendi l'unità principale. amplifier should power on, indicated by the LED status bar.

4.2 Regolazione dei controlli

Use the integrated adjustment tool to set the following parameters:

• Controllo di guadagno: Adjust the gain for each channel (CH1/2, CH3/4) to match the output level of your head unit. Start with the gain at minimum and slowly increase until desired volume is achieved without distortion. The LED status bar can assist in this process.
• Filter Settings (HPF/LPF):
  • HPF (filtro passa-alto): Allows frequencies above the set point to pass. Useful for protecting smaller speakers from low bass frequencies.
  • LPF (filtro passa-basso): Allows frequencies below the set point to pass. Typically used for subwoofers.
  The MA 4 features 12 dB/octave filters. Adjust the crossover frequencies according to your speaker setup and desired sound.
• Ingresso volumetage Controllo: Adjust this setting based on whether you are using high-level or low-level inputs to ensure proper signal matching.
• Input Resistance (Input Load): For high-level inputs, adjust the input resistance to optimize signal transfer from the head unit.

5. Manutenzione

L'ETON MA 4 amplifier è progettato per durare a lungo e richiede una manutenzione minima.

• Pulizia: Utilizzare un panno morbido e asciutto per pulire il ampl'esterno del filtro. Evitare detergenti abrasivi o solventi.
