ZK-TB21 Bluetooth 5.0 Subwoofer Amplifier Board 50WX2+100W 2.1 Channel Power Audio Stereo

Features:

【HIFI Stereo】

High quality dual channel power amplifier board for HIFI music. With AUX and Bluetooth two audio input methods. Bluetooth version 5.0 - the transmission efficiency is higher, the transmission distance is farther. With a filter inductor, the sound is round and clear.

【Protection Mechanism】

The TPA3116D2 devices feature short-circuit and thermal protection as well as overvoltage, undervoltage, and DC protection to prevent total failure. In the event of an overload, the device reports the fault condition to the processor to protect itself from damage.

[High Performance] The TPA3116D2 is a Class D amplifier IC from TI that has very high index parameters. Advanced oscillator / PLL circuit uses multiple switching frequency options to reject AM interference. The modulation frequency can be up to 1.2MHZ, and the high power output distortion is less than 0.1%. This helps prevent noise.

【High Quality】

It adopts copper DC connector and fence type terminal. It can withstand large current, no heat, no damage to the wire. Free DC head lead, compatible with the input power interface of this product, even if you dont have a DC head adapter or battery, it can be easily wired.

【Application】

With bass, treble and volume control, easy to adjust volume, enjoy the music tone what you want. TDA3116D2 is widely used in store solicitation, home theater, square speakers, etc.due to its excellent performance and comprehensive cost performance.
