ZK-1002 Bluetooth 5.0 Audio Amplifier Board, 100W x 2 2.0 Channel Mini Amp HiFi Power Amplifier Receiver with Volume Control, BT and AUX Inputs, DC 5-27V Stereo AMP Module for Home DIY Speakers

HIFI AUDIO AMPLIFIER BOARD: This ZK-1002 Mini Bluetooth audio amplifier board is a 2.0 channel amp, it can connect two passive speakers (20-200W, 4-8), DC7-24V/5A above. This power amplifier with two TPA3116D2 chips, 4 red and gray ring inductors, distortion rate below 0.3 %, and another upgrade large chips support AAC BT decoding, APP, low latency.
Mini SIZE BUT POWERFUL: ZK-1002 audio power amplifier with a very mini size is 8.5 x 5.3 x 2.2 cm / 3.35 x 2.08 x 0.87 inch, dual channel stereo output power 100W+100W, suitable for 4-8 speakers. It is recommended to use 50-100W speakers for the best effect.
BLUETOOTH 5.0 INPUTS: The Bluetooth power amplifier board with 2 kinds of inputs: AUX and Bluetooth inputs, the upgrade large chips support Bluetooth 5.0, low latency. The range of audio devices (smartphones, tablets, laptops, etc. ) with Bluetooth connectivity is 15m/49ft.
Note: When using AUX mode, please confirm that the Bluetooth connection of this module has been disconnected.

Details

and Quality: amplifier circuit board with 4 groups of red and gray ring inductors and 684 film capacitors, with low loss, high bandwidth, high fidelity characteristics; 2 pieces of TPA3116D2 chips have AM interference suppression, to ensure the high-power output, and low distortion (less than 0.3 %), the electrolytic capacitor array filtering effect is very good, ensure the output of the sound quality is more pure. They are specially customized for the ZK-1002 digital amplifier.
Multiple Protections and Safety: This ZK-1002 Bluetooth amp module with multiple protections ensure safety in use, designed with over-voltage protection, under-voltage protection, over-heat protection, short-circuit protection, with case to protect it.
