Precauzioni di sicurezza
- Garantire l'alimentazione voltage is within the specified DC 8-26V range. Incorrect voltage può danneggiare il dispositivo.
- Avoid short circuits on the output terminals.
- Non esporre la tavola all'umidità o a temperature estreme.
- Handle with care to prevent damage to electronic components.
- Scollegare l'alimentazione prima di effettuare qualsiasi collegamento o regolazione.
Caratteristiche del prodotto
The DROK 15W+15W Audio Amplifier Board is designed for high-fidelity audio applications, offering robust performance and protective features:
- Ampio volume operativotage: DC 8-26V, compatible with 12V and 24V power sources.
- Elevata potenza in uscita: Delivers 15W stereo (24V 8ohm) or 10W stereo (12V 8 ohm). Automatically limits power to 15W for 4 ohm or 2 ohm speakers.
- Costruzione Premium: Features a black immersion gold circuit board, PAM8620 chip, imported KEMET speaker capacitors, large-capacity filter capacitors, black copper terminal blocks, and gold-plated audio input terminals.
- Alte prestazioni: Potenza di classe D amplifier module with over 90% efficiency, general harmonic distortion noise less than 0.2%, low quiescent current, and noise suppression.
- Protezione completa: Includes input reverse connection protection, short circuit protection, over-heat protection, overcurrent protection, overvoltage protezione e undervoltage protection. EMI is also allowed to pass.
- Funzioni aggiuntive: Supports external mute function (MUTE: High level mute, factory default low level) and external shutdown (SD: chip shuts down at low electricity level, factory default high electricity level).

Contenuto della confezione
Il pacchetto tipicamente include:
- 1x DROK 15W+15W PAM8620 Audio AmpLifier Board
- (Note: Power supply and speakers are not included and must be purchased separately.)
Impostare
Segui questi passaggi per configurare il tuo ampscheda di supporto:
- Collegamento elettrico: Connect a DC 8-26V power supply to the "DC8-26V" terminal block. Ensure correct polarity (DC power+ and DC power-).
- Collegamento dell'altoparlante: Connect your speakers to the output terminal blocks. The right channel speaker connects to "Right channel speaker" terminals (R+ and R-), and the left channel speaker connects to "Left channel speaker" terminals (L+ and L-). Ensure correct polarity for each speaker.
- Ingresso audio:
- 3.5mm Audio Cable (Single-ended input): Connect a 3.5mm audio cable to the "Single input port". If using this input, ensure the two jumpers (labeled "SE-IN") are removed.
- RCA Input (Differential input): Connect RCA cables to the "DiffIN-R" (Right) and "DiffIN-L" (Left) ports. This input is for audio equipment supporting differential output. If using this input, ensure the two jumpers (labeled "SE-IN") are installed.

Istruzioni per l'uso
Once all connections are securely made and power is applied:
- Regolazione del volume: Use the "VOLUME" knob to adjust the audio output level. Rotate clockwise to increase volume, and counter-clockwise to decrease volume.
- Funzione muto: The board supports an external mute function. By default, the mute is at a low level. A high-level signal applied to the MUTE pin will mute the audio output.
- Funzione di spegnimento: The board supports an external shutdown function. By default, the shutdown is at a high electricity level. A low-level signal applied to the SD pin will shut down the chip.

Manutenzione
- Mantieni il ampScheda di controllo pulita e priva di polvere. Per la pulizia, utilizzare un panno morbido e asciutto.
- Ensure adequate ventilation around the board to prevent overheating, especially during prolonged use at high volumes.
- Controllare regolarmente tutti i collegamenti per verificarne la tenuta e la corrosione.
- Avoid placing heavy objects on the board or subjecting it to physical shock.
Risoluzione dei problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Nessuna uscita audio | Incorrect power connection, loose speaker wires, incorrect audio input selection (jumpers), muted state, or low volume. | Verify power supply and polarity. Check all speaker and audio input connections. Ensure correct jumper settings for single-ended or differential input. Adjust volume. Check mute/shutdown status. |
| Audio distorto | Input signal too high, speaker impedance mismatch, or faulty speaker. | Reduce input signal level. Ensure speakers are within the recommended 4-8 Ohm range. Test with different speakers. |
| Surriscaldamento | Lack of ventilation, prolonged high-volume use, or short circuit. | Ensure proper airflow around the board. Reduce volume or usage time. Check for short circuits. |
| Ronzio o rumore | Ground loop, interference from other electronics, or poor quality audio cables. | Ensure proper grounding. Separate audio cables from power cables. Use shielded audio cables. Consider a ground loop isolator if necessary. |
