ZK TB21 2.1 Channel BT5.0 Digital Power Amplifier Modules with TPA3116D2 Chip

Features:
OOTDTY  
HIFIStereo, a highquality dualchannel power amplifier board for HIFImusic
It supports both AUXinput and Bluetoothconnection (BT5.0) for highertransmission efficiency and longer distances
The integrated highPerformance processor chip is a ClassD amplifier integrated circuit. The modulation frequency can reach 1.2 MHz, and the distortion of highpower output is less than 0.1%. Built in LCfilter capacitor, making the humanvoice clearer.
Both AUXand Bluetoothcompatible inputs are supported, supporting Bluetoothcompatible version 5.0.
The transmission distance is longer, reaching up to 49 feet in outdoor environments. If your device does not have a Bluetoothcompatible modules, you can also input audiosignals through the 3.5mm headphoneplug.
Protections mechanism: The amplification board has overheating protections, overvoltage protections, undervoltage protections, and short-circuit protections
