Product Features

1. Genuine TPA3116D2 Chip (Imported)
   • Texas Instruments (TI) Class-D digital amplifier IC with 90% efficiency, minimizing heat generation for prolonged high-volume playback.
2. Dual 80W Stereo Output
   • 80W per channel (4Ω load, THD+N=10%), total 160W power handling—ideal for driving 6–10-inch professional speakers.
3. Onboard Tone Control
   • Adjustable bass (Bass) and treble (Treble) via built-in potentiometers, catering to genres like pop, classical, and rock.
4. Ultra-Low Distortion & High SNR
   • Total Harmonic Distortion (THD) <0.05%, Signal-to-Noise Ratio (SNR) ≥100dB, ensuring crystal-clear audio with no background noise.
5. Wide Voltage Compatibility
   • Supports DC12V–24V input, compatible with car batteries, switching power supplies, and solar systems.

Key Advantages

✅ High Power, Low Heat

• Class-D efficiency reduces energy waste by 60% compared to AB-class amplifiers. Includes a heatsink for 8+ hours of continuous operation.
  ✅ Plug-and-Play Simplicity
• Standard 3.5mm audio input and screw terminal speaker outputs. Complete setup in 10 minutes with included wiring diagrams.
  ✅ Cost-Effective Integration
• 40% cheaper than discrete component designs, with 70% fewer failure points due to modular architecture.
  ✅ Multi-Scenario Flexibility
• Supports 4Ω–8Ω speakers; parallel two boards for mono 160W output (e.g., subwoofer applications).

Applications

1. Home Theater Upgrades
   • Replace weak TV/projector amplifiers by pairing with bookshelf speakers + subwoofer for immersive 5.1 surround sound (requires external decoder).
2. Car Audio Modifications
