ZK-TB21 2x50W+100W 2.1 Channel HiFi Subwoofer Digital Power Amplifier Board with Filter AUX Audio Stereo Bluetooth-compatible 5.0 Bass Amp Module
Feature:
The Bluetooth-compatible audio power amplifier module has 2.1 channels and the maximum output power is 2X50W+100W.
It has two audio input modes, AUX and Bluetooth-compatible, and a two-in-one power amplifier board. Bluetooth-compatible5.0, higher transmission efficiency, longer transmission distance
Chip solution TPA3776D2, with AM interference suppression function; output filter, HiFi sound quality, relatively low requirements for speakers.
Pure HiFi fever sound quality. The treble is pure and transparent, the midrange is gentle and delicate, and the bass is surging and shocking.
It has short-circuit protection, over-current, over-heating, and anti-reverse protection to prevent total failure. When an overload occurs, the device reports the fault condition to the processor to protect itself from damage.
It adopts copper DC connectors and barrier terminals. It can withstand high current without heating or damaging wires.
Using a dedicated 50x25x10mm large-area heat sink, close to the copper-clad shell for heat dissipation, the heat dissipation area is doubled to ensure that the product runs at full power and high performance.
With bass, treble, subwoofer frequency and volume control, you can easily adjust the volume and enjoy the music tone you want. Widely used in shopping malls, home theaters, speakers, etc.

Tip:
When the audio input is enough and the power supply voltage/current is enough, there will be enough output power!!! The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power!!!
Please make sure that the power of the adapter power is greater than the actual working power of the amplifier!!!

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
