- Avoid short circuits on the output terminals.
- Do not expose the board to moisture or extreme temperatures.
- Handle with care to prevent damage to electronic components.
- Desconnecteu l'alimentació abans de fer qualsevol connexió o ajust.
Característiques del producte
The DROK 15W+15W Audio Amplifier Board is designed for high-fidelity audio applications, offering robust performance and protective features:
- Ampli vol operatiutage: DC 8-26V, compatible with 12V and 24V power sources.
- Alta potència de sortida: Delivers 15W stereo (24V 8ohm) or 10W stereo (12V 8 ohm). Automatically limits power to 15W for 4 ohm or 2 ohm speakers.
- Construcció 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.
- Alt rendiment: Potència de classe D amplifier module with over 90% efficiency, general harmonic distortion noise less than 0.2%, low quiescent current, and noise suppression.
- Protecció integral: Includes input reverse connection protection, short circuit protection, over-heat protection, overcurrent protection, overvoltage protecció, i undervoltage protection. EMI is also allowed to pass.
- Funcions addicionals: 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).

Contingut del paquet
El paquet normalment inclou:
- 1x DROK 15W+15W PAM8620 Audio AmpJunta més viva
- (Note: Power supply and speakers are not included and must be purchased separately.)
Configuració
Segueix aquests passos per configurar el teu amptauler de vidació:
- Connexió d'alimentació: Connect a DC 8-26V power supply to the "DC8-26V" terminal block. Ensure correct polarity (DC power+ and DC power-).
- Connexió de l'altaveu: 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.
- Entrada d'àudio:
- 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.

Instruccions de funcionament
Once all connections are securely made and power is applied:
- Ajust de volum: Use the "VOLUME" knob to adjust the audio output level. Rotate clockwise to increase volume, and counter-clockwise to decrease volume.
- Funció de silenci: 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.
- Funció d'apagada: 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.

Manteniment
- Mantenir el ampMantingueu la placa del lifter neta i sense pols. Feu servir un drap suau i sec per netejar-la.
- Ensure adequate ventilation around the board to prevent overheating, especially during prolonged use at high volumes.
- Regularly check all connections for tightness and corrosion.
- Avoid placing heavy objects on the board or subjecting it to physical shock.
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Sense sortida de so | 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. |
| Àudio distorsionat | 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. |
| Sobreescalfament | 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. |
| Humming or noise | 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. |
