Over-temperature and short-circuit protection against static electricity
Support BT, AUX, U disk, USB sound card input
With heat sink

Audio Input: AUX+ Bluetooth+U disk + USB sound card
Channel: 2.0 (stereo)
Power Range: DC9-24V/4A above (high power recommended high voltage)
Adapter Speaker: 20W-100W, 4-8 ohm
Protection Mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection
PS: In the audio input is enough, the supply voltage/current is enough, there will be enough output power! The higher the supply voltage, the greater the output power. The smaller the impedance of the speaker, the greater the output power! Please ensure that the power of the adaptor is greater than the actual working power of the amplifier
