The PAM8610 2x15W Dual Channel Stereo Class D Amplifier Board is a high-efficiency digital audio power amplifier module designed to deliver powerful, clear stereo sound with minimal power consumption, making it ideal for a wide range of DIY audio projects and speaker upgrades.
Description
The PAM8610 2x15W Dual Channel Stereo Class D Amplifier Board is a compact yet robust solution for audio amplification needs. Utilizing the advanced PAM8610 digital amplifier chip, this module operates as a highly efficient Class D amplifier, which translates into less heat generation and lower power consumption compared to traditional Class AB amplifiers. It is capable of delivering a substantial 15 watts per channel into 4-ohm speakers (or 10W per channel into 8-ohm speakers), providing excellent sound quality for bookshelf speakers, desktop audio systems, portable boomboxes, or car audio retrofits.
This amplifier board operates on a wide DC input voltage range of 7V to 15V, with 12V DC being the recommended and optimal operating voltage. A key feature is the integrated volume potentiometer, allowing users direct control over the audio output level without the need for external components. The board also includes reverse polarity protection to safeguard the circuit from accidental power connection errors.
Designed for simplicity, the module offers a straightforward three-wire audio input (Left Channel, Right Channel, Ground) and easy screw-terminal outputs for connecting two passive speakers. Its high signal-to-noise ratio and low quiescent current make it a reliable choice for achieving clear, high-fidelity sound in both hobbyist and professional audio projects.
Features
  • High-Efficiency Class D: Utilizes Class D amplifier technology for 90% or greater power efficiency, reducing heat and extending battery life in portable applications.
  • Powerful Output: Delivers up to 15 watts per channel (at 4Ω load) or 10 watts per channel (at 8Ω load) for robust stereo sound.
  • Wide Voltage Operation: Operates on a flexible DC input range of 7V to 15V (12V recommended).
  • Integrated Volume Control: Onboard potentiometer allows for easy adjustment of the output volume.
  • Reverse Polarity Protection: Built-in protection circuit helps prevent damage if the power supply is connected incorrectly.
  • High Fidelity Audio: Features a high signal-to-noise ratio and low total harmonic distortion for clear sound reproduction.
  • Compact Design: Small form factor makes it easy to integrate into tight spaces and existing speaker enclosures.
Usage
The PAM8610 amplifier board is straightforward to wire and use:
  1. Power Connection: Connect a DC power source (preferably 12V, 2A or higher) to the power input terminals. Ensure correct polarity (positive/negative). The board includes protection, but correct wiring is always best practice.
  2. Speaker Connection: Connect your passive speakers (4Ω or 8Ω impedance is compatible) 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, decoder board, computer audio out) to the 3-pin audio input pads using 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.
Q: Can I power this board with a 5V USB power supply?

No, the PAM8610 chip requires a minimum of 7V DC input to operate correctly and deliver full power. The optimal performance is achieved at 12V DC. Using 5V will result in no or poor functionality

Q: Does this module produce a lot of heat?

Because it is a highly efficient Class D amplifier (over 90% efficiency), it generates very little heat compared to older amplifier technologies. A heatsink is generally not required for typical use

Q: Why do I hear noise when I turn up the volume?

Noise usually stems from the power supply or the audio input cabling. Ensure you use a stable, low-noise power supply (not a switching power supply if possible) and use shielded audio cables for the input connections to prevent interference

Q: What type of speakers are compatible?

The board is compatible with passive speakers having an impedance of 4 ohms or 8 ohms. 4-ohm speakers will provide the maximum 15W output, while 8-ohm speakers will produce about 10W

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

A slight pop sound upon power-up is a common characteristic of many simple Class D amplifier modules without advanced soft-start circuits. This is normal and typically does not harm the speakers. You can mitigate this by powering the audio source first, then the amplifier board
