The PAM8610 12V Dual Channel Digital Amplifier Board is a compact, high-efficiency Class D stereo audio module capable of delivering high-definition, pure digital sound with a power output of 15W per channel, ideal for various DIY audio projects.
Description
The PAM8610 12V Dual Channel Digital Amplifier Board provides a robust and crystal-clear audio solution in a miniature form factor. Utilizing the advanced PAM8610 digital amplifier chip, this module operates in high-efficiency Class D mode, ensuring minimal power loss and significantly less heat generation compared to traditional linear amplifiers. This efficiency makes it suitable for continuous use in both stationary home audio setups and portable, battery-powered applications.
The board is optimized for a 12V DC power input, at which it can deliver a powerful 15 watts per channel into a 4-ohm speaker load, or a slightly reduced output into an 8-ohm load. The design focuses on simplicity and ease of use, featuring an onboard volume control potentiometer that doubles as a power switch when fully counter-clockwise.
Connections are straightforward: screw terminals are provided for the power input (7V-15V range) and the left/right speaker outputs. A 3-pin header is available for the audio input from sources like smartphones, MP3 players, or Bluetooth decoder boards. The board includes basic reverse polarity protection and is designed to produce high-fidelity stereo audio with very low distortion, making it a reliable choice for audio enthusiasts and businesses alike.
Features
  • High-Efficiency Class D Technology: Ensures over 90% power efficiency, reducing heat output and power consumption.
  • Powerful Stereo Output: Delivers up to 15W per channel (into 4Ω speakers @ 12V DC) for loud and clear sound.
  • Optimal 12V Operation: Designed for a DC input voltage range of 7V to 15V, with 12V being the recommended optimal voltage.
  • Integrated Volume/Power Control: Onboard potentiometer manages volume and power on/off functionality.
  • HD Audio Quality: Provides high-definition stereo sound with excellent signal-to-noise ratio and low total harmonic distortion.
  • Reverse Polarity Protection: Built-in protection mechanism to safeguard the circuit from incorrect power connections.
  • Compact Design: Small footprint allows for easy integration into existing enclosures or custom-built speakers.
Usage
The PAM8610 amplifier board is straightforward to wire and use:
  1. Power Connection: Connect a stable DC power source (ideally 12V, 2A or higher) to the power input screw terminals. The board will power on as the volume knob is turned clockwise from its off position.
  2. Speaker Connection: Connect your passive speakers (4Ω or 8Ω impedance) to the corresponding left and right channel output screw terminals (SPK_L and SPK_R). Observe positive (+) and negative (-) terminals.
  3. Audio Input: Connect your audio source (phone, MP3 player, computer audio out) to the 3-pin audio input pads using a shielded cable to minimize interference. The pins are typically labeled L (Left), R (Right), and GND (Ground).
  4. Volume Adjustment: Use the onboard potentiometer to adjust the desired volume level and turn the unit off when not in use.
Q: Can I use a different voltage other than 12V?
Yes, the board operates within a range of 7V to 15V DC. However, 12V is the optimal voltage for achieving the specified 15W output power and best performance. Operating below 7V will not work; operating above 15V risks damaging the chip.
Q: Does this module produce audible noise or hum?

When using a clean, stable power supply (like a lead-acid battery or a quality regulated 12V adapter) and shielded audio input cables, the board produces minimal noise. Noise is often introduced by poor quality switching power supplies or ground loops.

Q: Is there any "pop" sound when the board powers on?

A slight pop sound upon power-up is typical for simple Class D modules without advanced soft-start circuits. This is a normal function and generally harmless to speakers.

Q: What is the primary advantage of Class D amplification here?
The main advantage is efficiency. The board converts nearly all input power into audio output rather than wasted heat, making it cooler to run and more energy-efficient than older amplifier types.
Q: Can I use this board in a car?
Yes, the 12V operating voltage makes it very suitable for car audio systems. Ensure your power source in the car is stable and filtered for optimal audio quality.
