High Quality. Power :2.1 inferince 8-24V DC power supply . Audio input : Stereo input various verisions of the bluetooth connection,using CSR8635 Bluetooth chip,Bluetooth V4.0,high software compatibility. Output Impedance :8 ohms Best (4,6,8,16 ohms impedance can diver speaker) *Output Power :Add pre-5532 output foot (powered 25V ,6-ohm impedance output 2*50W ,8 ohm impedance output 2*40W dual-channel). TDA 7492 digital amplifier chip ,designed to optimize the circuit layout ,the sound quality is very good ,big power . DIP switches can be more easily directly adjusted after-class amplifier gain,to better promote the impedance larger speakers. If you use extral audio,you need connect 3.5mm audio line. If you directly use Bluetooth,when power ,wait 3s~10s ,until led Blue and Red light flashing alternately,then you can use you device to find my Bluetooth module ,you will find “SANWU Audio “,then connect it ,can directly use it .
