TPA3116D2 Dual Channel Digital Audio Amplifier Board, 2×120W High Power Class D Amp Module, DC8-28V Wide Voltage, Independent L/R Volume Knobs, Built-in Heat Sink, 4-8Ω Speaker for DIY Speaker, Car Audio & Home Stereo System.
Description
Product Overview
This TPA3116D2 high-power digital amplifier board adopts original TPA3116D2 Class D audio chip, delivering up to 120W output power per channel (total 240W stereo power). It supports wide DC 8~28V input voltage (24V power supply recommended), equipped with independent left & right channel volume potentiometers and integrated large aluminum heat sink for stable heat dissipation. Compatible with 4Ω~8Ω passive speakers, it fully decodes mainstream lossless audio formats including MP3, FLAC, APE, WAV and WMA, widely applied to DIY active speakers, car audio upgrade, home stereo sound system and small portable audio equipment.
Core Product Advantages
✅ Original TPA3116D2 High Efficiency Chip
Class D design with over 90% energy conversion efficiency, low EMI interference noise. Built-in multi-protection circuits: overvoltage, undervoltage, overheat and short-circuit protection to effectively protect speakers and power supply.
✅ 2×120W High Stereo Output Power
Matched with high-capacity filter electrolytic capacitors and high-frequency inductors, output pure high-fidelity stereo sound, perfectly drive 4Ω~8Ω speakers; speakers above 200W are recommended for optimal sound performance.
✅ Independent Left & Right Volume Adjustment
Dedicated volume potentiometers for left and right channels, users can freely adjust stereo balance without extra preamplifier board.
✅ Large Integrated Aluminum Heat Sink
Full coverage black aluminum heat sink for power chips, fast heat dissipation, supports long-term continuous high-power playback without overheating.
✅ Wide Voltage Input & Pluggable Terminal Blocks
DC 8V~28V wide voltage range, green detachable terminal blocks for power, speaker and audio signal wiring, no soldering required for quick assembly.
✅ Universal Lossless Audio Decoding
Compatible with all mainstream lossless music formats, works with mobile phones, computers, MP3 players and preamp boards as audio input sources.

Board Wiring Definition Guide
- Power Terminal Block (VCC / GND / STBY) VCC: Power positive input; GND: Power ground; STBY: Standby pin, connect to VCC to activate normal working mode
- Speaker Output Terminals Left Channel OUT+/OUT- & Right Channel OUT+/OUT-, connect two passive speakers separately
- Audio Input Socket (3P) INL (Left audio signal) / GND / INR (Right audio signal), connect to audio source output
- Volume Knobs VOL L: Left channel volume adjustment; VOL R: Right channel volume adjustment
Step-by-Step Operation Instructions
- Power Connection: Connect DC 8~28V power supply; 24V 6A adapter is the optimal choice to reach full 120W single-channel power.
- Audio Source Input: Plug the 3P audio cable to connect mobile phone, PC, MP3 or preamplifier board to the audio input port.
- Speaker Connection: Wire 4~8Ω passive speakers to left/right output terminals; 200W+ professional stage speakers are suggested for better sound effect.
- Volume Tuning: Rotate the two independent potentiometers to balance left and right channel volume before playback.
Application Scenarios
- Home Audio: DIY desktop active speakers, living room stereo audio system
- Car Modification: Vehicle audio power amplifier, RV audio upgrade
- Electronic DIY: Bluetooth speaker power amplifier module, audio player power output unit
- Portable Audio: Mini outdoor speaker, small stage audio drive equipment
Warm Reminders
- Do not connect speakers with impedance lower than 4Ω, which will cause chip overheating and permanent damage.
- Do not exceed 28V input voltage; 24V power supply is required to achieve full rated power output.
- Keep the heat sink unobstructed during long-time high-power operation to ensure heat dissipation efficiency.
- Product appearance and parameters may be updated without prior notice, please refer to the physical product you receive.
