Power: 2.1 interface 8 ~ 24V DC power supply

Audio input: stereo input various versions of the Bluetooth connection, using CSR8635 Bluetooth chip, Bluetooth V4.0, high software compatibility plus AUX

Output Impedance: 8 ohms Best(4,6,8,16 ohm impedance can drive speakers)

Output Power: Add pre-5532 output foot (powered 25V ,6-ohm impedance output 2 X 50W, 8 ohm impedance output 2X40W dual-channel)

TDA7492 digital amplifier chip, designed to optimize the circuit layout, the sound quality is very good, big power

DIP switches can be adjusted directly after the amp gain more respect and better promote greater damping horn

Attention!

this module has also a 3.5mm jack input that can be used as karaoke input hear your voice over the track playing via bleutooth if you want to use it as aux input without having to enable bleutooth you have to make a bridge in to pins as shown in the picture below
