1. Power Supply Connection

• Identify the VCC and GND terminals on the module (refer to Figure 4).
• Connect the positive (+) terminal of your DC power supply (8V to 24V) to the VCC terminal.
• Connect the negative (-) terminal of your DC power supply to the GND terminal.
• Caution: Ensure the power supply voltage is within the specified range (DC 8-24V) and observe correct polarity to prevent damage to the module.

2. Audio Input Connection

• Locate the IN+ and IN- terminals for audio input (refer to Figure 4).
• For single-ended input, connect the audio signal source's positive output to IN+ and the ground/negative output to IN-.
• The module supports differential input; consult advanced documentation if this configuration is required.

3. Speaker Output Connection

• Identify the SPK+ and SPK- terminals for speaker output (refer to Figure 4).
• Connect the positive (+) terminal of your speaker to SPK+.
• Connect the negative (-) terminal of your speaker to SPK-.
• Ensure the speaker impedance is between 4Ω and 8Ω. Using speakers outside this range may result in reduced performance or damage.

Operating Instructions

Once all connections are securely made, you can begin operating the amplifier module.

1. Power On: Apply power to the DC 8-24V input. The module should power on.
2. Audio Playback: Start playing audio from your connected source.
3. Volume Control: Volume is controlled by the audio source device. The amplifier module provides fixed gain amplification.
4. Power Off: Disconnect the power supply when the module is not in use.

Maintenance

To ensure the longevity and reliable operation of your DY-AP3001 amplifier module, follow these maintenance guidelines:

• Keep Clean: Regularly clean the module with a soft, dry cloth. Avoid using liquids or solvents.
• Avoid Dust: Operate the module in a clean, dust-free environment to prevent accumulation on components.
• Proper Ventilation: Ensure adequate airflow around the module, especially during extended operation, to prevent overheating.
• Handle with Care: Avoid dropping or subjecting the module to physical shock.
• Storage: When not in use for extended periods, store the module in a dry, cool place, away from direct sunlight and extreme temperatures.
