Informazioni sulla sicurezza

Please read and understand the following safety precautions before operating the ampscheda di supporto:

• Garantire l'alimentazione voltage is within the specified range (DC 8V-19V). Exceeding this range can damage the board.
• Scollegare l'alimentazione prima di effettuare qualsiasi collegamento o scollegamento.
• Avoid short-circuiting speaker outputs or power supply terminals.
• Do not expose the board to moisture, extreme temperatures, or static electricity.
• Handle the board by its edges to prevent damage to components.
• This product is intended for experienced users familiar with electronic components and wiring.

Configurazione e collegamenti

Refer to the images below for visual guidance on connecting the ampbordo dell'allevatore.

Figura 1: in alto view of the AA-AB32231 ampbordo dell'allevatore.

This image displays the top side of the amplifier board, highlighting the various connection points. On the left, you can see the DC power input terminals (GND and VCC). The audio input jack is visible on the top left, and speaker output terminals (OUT1+, OUT1-, OUT2+, OUT2-) are located on the top and right sides of the board.

1. Collegamento dell'alimentazione

• Connect a DC power supply (8V to 19V) to the "DC IN 8-19V" terminals (J1) on the left side of the board.
• Ensure correct polarity: connect the positive (+) terminal of the power supply to VCC and the negative (-) terminal to GND.
• A 12V or 16V power supply is generally recommended for optimal performance. Note that some 9V power supplies may not provide sufficient voltage per il corretto funzionamento.

2. Connessione di ingresso audio

• The board offers two audio input methods:
  1. 3.5mm Audio Jack (J3): Connect your audio source (e.g., smartphone, MP3 player, computer) directly to the 3.5mm stereo input jack.
  2. Solder Terminals (J2): For custom installations, audio input can be wired directly to the "GND", "IN1", and "IN2" solder pads.

3. Collegamento uscita altoparlante

• Connect your speakers to the "OUT1" and "OUT2" terminals.
• For Channel 1 (OUT1): Connect the positive (+) terminal of the speaker to OUT1+ and the negative (-) terminal to OUT1-.
• For Channel 2 (OUT2): Connect the positive (+) terminal of the speaker to OUT2+ and the negative (-) terminal to OUT2-.
• Ensure speakers have an impedance of 4 Ohms for optimal 8W output.

Questo angolato view provides a clearer perspective of the screw terminals for speaker outputs and power input, as well as the 3.5mm audio input jack. It also illustrates the compact form factor of the ampbordo dell'allevatore.

4. Mode Selection (Mono/Stereo, BTL/PBTL)

The board features switches on the underside for configuring the output mode. Refer to Figure 3 for switch locations.

Figura 3: In basso view of the AA-AB32231 amplifier board with mode switches.

This image shows the underside of the amplifier board, where SW1 and SW2 are located. These switches control the operating mode, allowing selection between stereo (DIFF/SE) and mono (BTL/PBTL) configurations. The labels indicate the specific settings for each switch position.

• SW1 (MODE): Selects between BTL (Bridge-Tied Load) and PBTL (Parallel Bridge-Tied Load) modes.
• SW2 (MODE): Configures the input and output differential/single-ended modes. The combination of SW1 and SW2 determines the final operating mode (e.g., stereo differential input, mono BTL output).
• Consult the markings on the board for specific switch positions corresponding to desired modes (e.g., "SHORT IN MONO MODE" for mono input).
• Ensure the board is powered off before changing switch settings.

Istruzioni per l'uso

1. After all connections (power, audio input, speakers) are securely made, apply power to the board.
2. The power indicator LED (if present) should illuminate.
3. Avvia la riproduzione dell'audio dal dispositivo sorgente.
4. Adjust the volume using your audio source device. This amplifier board typically operates at a fixed gain.
5. If no sound is heard, refer to the Troubleshooting section.

Specifiche

Risoluzione dei problemi

• Nessun suono:
  • Check power supply connections and ensure the power LED is on.
  • Verify audio input cable is securely connected to both the source and the ampbordo dell'allevatore.
  • Ensure speaker wires are correctly connected to the output terminals and not short-circuited.
  • Confirm the audio source is playing and its volume is turned up.
  • Check the mode switches (SW1, SW2) on the underside of the board to ensure they are set for the desired stereo or mono operation.
• Suono distorto:
  • Reduce the volume from the audio source. Overdriving the input can cause distortion.
  • Assicurarsi che l'alimentazione sia stabile e fornisca corrente sufficiente.
  • Verificare che l'impedenza dell'altoparlante corrisponda a amplifier's requirements (4 Ohms recommended).
• Intermittent Sound or Muting:
  • Some power supplies, particularly 9V, may not provide stable operation. Try a 12V or 16V power supply.
  • Check for loose connections on power, input, or output terminals.
  • Ensure the board is not overheating. Provide adequate ventilation if enclosed.

Manutenzione

The Sure Electronics AA-AB32231 amplifier board requires minimal maintenance:

• Mantenere la scheda pulita e libera da polvere e detriti. Utilizzare una spazzola morbida e asciutta o aria compressa per la pulizia.
• Avoid touching the electronic components directly, especially when powered.
• Quando non viene utilizzata, conservare la tavola in un ambiente fresco e asciutto.
• Controllare regolarmente la tenuta e la corrosione dei collegamenti.
