HT21-3G 2.1 Channel TDA7498E Bt Amplifier Module Subwoofer 160Wx2+220V Treble Bass Wuzhi Audio Supports APP

Features:

1. Upgraded power output: HT21-3G provides higher power output capability, suitable for driving more types and larger scale speaker systems, meeting the needs of professional audio scenes.

2. Optimized sound quality performance: Advanced audio processing technology and selected electronic components are used, and the magnetic shielding mechanism has strong anti electromagnetic interference (EMI) performance, ensuring minimal sound quality loss during audio amplification and providing a purer and more dynamic sound experience.

3. Third generation circuit design: Supports APP and TWS pairing, improving overall efficiency and stability.

4. Enhanced heat dissipation solution: Given the demand for high-power operation, the power amplifier board may be equipped with enhanced heat sinks or active heat dissipation systems to ensure the reliability and safety of the equipment under long-term use.

5. Comprehensive protection system: Built in multiple protection mechanisms including overheating, overcurrent, and short circuit, effectively defending against external abnormal conditions and protecting the amplifier from damage.

Tips:

1. Only when the audio signal input is large enough and the power supply voltage/current is large enough, will there be enough

Output power!

2. The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power!

3. Please ensure that the power of the adapted power supply is greater than the actual working power of the amplifier!
