- Power Input (+12V, REM IN, GND): Connections for main power, remote turn-on, and ground.
- Speaker Outputs (CH1, CH2, Bridge): Terminals for connecting speakers in stereo or bridged mono configuration.

- Input (CH1, CH2): RCA inputs for connecting the audio source (e.g., head unit).
- Output (CH1, CH2): RCA outputs for passing the signal to another amplifier (if applicable).
- GUANY: Input sensitivity control to match the output of your source unit.
- HPF (filtre de pas alt): Adjusts the high-pass crossover frequency (50-12000 Hz).
- LPF (filtre de pas baix): Adjusts the low-pass crossover frequency (50-12000 Hz).
- Interruptor de creuament: Selects between HPF, FLAT (full range), or LPF operation.
- Indicadors d'encesa/protecció: LEDs indicating amplifier status. 'Power' illuminates when the amplifier is on; 'Protect' illuminates during fault conditions.
5. Configuració i instal·lació
5.1. Muntatge del Ampmés viu
Choose a mounting location that provides adequate ventilation and protection from moisture. Secure the amplifier firmly to a solid surface using appropriate hardware. Avoid mounting on carpet or directly to metal surfaces without insulation.
5.2. Connexions de cablejat
Assegureu-vos que totes les connexions estiguin ben fixades i degudament aïllades per evitar curtcircuits.
5.2.1. Power, Ground, and Remote Wiring
- +12V (Alimentació): Connect to the positive terminal of the vehicle's battery using a fuse holder within 18 inches of the battery. Use 4 Ga wire for this connection.
- GND (terra): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a good electrical connection. Use 4 Ga wire for this connection, keeping the length as short as possible.
- REM IN (Remote Turn-On): Connect to the remote output of your head unit. This wire turns the ampencendre i apagar el lificador amb la unitat principal.
5.2.2. Input Signal Wiring
Connect the RCA cables from your head unit's pre-out to the amplifier's RCA input terminals (CH1, CH2).
5.2.3. Cablejat d'altaveus
Connecteu els vostres altaveus al amplifier's speaker output terminals. The MFA-2.320 supports both stereo and bridged mono configurations.
- Stereo Mode (2-Channel): Connect one speaker to CH1 outputs (+ and -) and another speaker to CH2 outputs (+ and -). Ensure the minimum permissible load per channel is 2 Ohms.
- Bridged Mono Mode (1-Channel): To bridge the amplifier for a single, higher power output, connect the speaker's positive terminal to the CH1+ terminal and the speaker's negative terminal to the CH2- terminal. Ensure the minimum permissible load in bridged connection is 4 Ohms. This configuration combines the power of both channels into one.
Use 10 Ga wire for speaker connections.
6. Instruccions de funcionament
6.1. Ajust de guany
El control de GUANY coincideix amb el ampla sensibilitat d'entrada del lificador al nivell de sortida de la unitat principal. Per configurar el guany:
- Gireu el amplifier's GAIN control to its minimum (counter-clockwise) position.
- Ajusteu el volum de la unitat principal a aproximadament un 75-80% del seu nivell màxim.
- Interpretar una peça musical dinàmica.
- Augmenta lentament el amplifier's GAIN control until you hear distortion, then back it off slightly until the sound is clear.
6.2. Configuració del crossover
The MFA-2.320 features adjustable High Pass Filter (HPF) and Low Pass Filter (LPF) with a 12 dB/Octave slope. The LPF and HPF can operate simultaneously.
- HPF (filtre de pas alt): Allows frequencies above the set point to pass through. Use this for full-range speakers or tweeters to prevent low frequencies from damaging them.
- LPF (filtre de pas baix): Allows frequencies below the set point to pass through. Use this for subwoofers to prevent high frequencies from playing.
- PIS: Disables both HPF and LPF, allowing the full frequency range (20-20000 Hz) to pass through.
Adjust the HPF and LPF controls according to your speaker types and desired sound characteristics. For example, if using full-range speakers, you might set the HPF to 80 Hz to remove damaging low bass. If using a subwoofer, you would set the LPF to around 80-100 Hz.
7. Manteniment
To ensure long-term performance of your ampmés viu:
- Mantenir el ampMantingueu el llifador net i sense pols. Feu servir un drap suau i sec per netejar-lo.
- Ensure that the cooling fins are not obstructed to allow for proper heat dissipation.
- Comproveu regularment totes les connexions del cablejat per verificar si estan ben ajustades i si hi ha corrosió.
8. Solució De Problemes
Si tens problemes amb el teu amplifier, refer to the following common issues and solutions:
| Problema | Causa possible | Solució |
|---|---|---|
| Sense alimentació / LED d'alimentació apagat | Fusible fundit, mala connexió d'alimentació/terra, sense senyal remot. | Check inline fuse, verify +12V, GND, and REM IN connections. |
| LED de protecció encès | Short circuit in speaker wiring, speaker impedance too low, overheating, DC offset. | Check speaker wiring for shorts, ensure correct speaker impedance, allow amplifier to cool, consult professional. |
| Sense so | No hi ha senyal d'entrada, configuració de guany incorrecta, cables d'altaveu desconnectats. | Verify RCA input connections, adjust gain, check speaker wiring. |
| So distorsionat | Guany massa alt, mala connexió a terra, altaveus danyats. | Reduce gain, improve ground connection, inspect speakers. |
