instructions:
TPA3116D2 digital amplifier board, with dual channel, high power, and stunning volume; The input voltage is DC12~28V, and it is recommended to use DC24V; On board operational amplifier chip TL074C, after the sound source is input, it is first amplified by the operational amplifier chip, which makes the volume more shocking.
Operation:
1. Connect the power input terminal to a DC DC12V-28V power supply (24V is recommended):
2. Connect the audio input terminal to the audio source, such as MP3 player, mobile phone, computer, etc;
3. Connect the audio output terminal to the speaker, paying attention to the positive and negative poles. It is recommended to connect a professional stage speaker with a power of 120W or more to fully utilize its effects.
Core Product Advantages
- HiFi-Grade Pure Sound Quality (THD < 0.02%)
- Utilizes TI NE5532 operational amplifier chips + independent power filtering, achieving a signal-to-noise ratio (SNR) of 110dB. Vocals are rendered with lifelike clarity, and instrument separation rivals amplifiers priced at $1,000+.
- Vs. Competitors: Ordinary digital amplifiers typically have distortion rates > 0.1%. This model’s ultra-low 0.02% distortion ensures crisp highs without harshness and tight, controlled lows.
- Dual-Channel 2×120W Continuous Output
- Delivers 120W RMS per channel at 8Ω, capable of driving 8-10-inch professional speakers. Testing shows a sound pressure level (SPL) of 105dB @ 1m when powering a pair of bookshelf speakers, easily covering a 50㎡ room.
- Dynamic Peak Power of 240W: Handles explosive movie scenes or musical crescendos without distortion or compression.
- Class-D High-Efficiency Design
- Boasts >90% conversion efficiency, consuming 60% less power than Class-AB amplifiers. After 4 hours of continuous operation, the chassis temperature reaches only 45°C, eliminating the need for noisy cooling fans.
- Wide Voltage Compatibility (DC12V-28)
- Supports 12V/24V/28V DC power supplies, compatible with professional audio power units, outdoor battery packs, or lab-grade regulated power sources. Operates stably even with ±10% voltage fluctuations.
Key Features
- Input Interfaces: Dual-mode XLR balanced input + RCA unbalanced input, compatible with professional mixers, players, PCs, and other devices while minimizing signal interference.
- Protection Mechanisms: Four-layer safety protection (overcurrent, short-circuit, overheating, and DC protection) with automatic fault recovery to prevent equipment damage.
- Easy Installation: Standardized 3.5mm heat sink mounting holes for direct integration into standard amplifier enclosures; screw-terminal outputs support bare wire/banana plug connections.
Application Scenarios
- Home Theater Upgrade
- Replace low-end AV receivers to power front main speakers (2×120W), paired with a subwoofer for 7.1-channel immersive sound. Bullet trajectories in movies are precisely localized during action scenes.
- Recording Studio Monitoring
- Provides clean, uncolored 120W power for near-field monitors (e.g., Yamaha HS8), ensuring accurate low-end representation and non-exaggerated highs during mixing.
- Live Performance Sound Reinforcement
- Serves as the main PA amplifier for small bands, driving two 10-inch full-range speakers to cover a 200-person venue with clear, penetrating vocals.
- DIY High-End Audio
- Retrofit vintage radios into smart speakers or build active tri-amped speaker systems at half the cost of branded amplifiers.
