Item Name: Power Amplifier Material: PCB Bluetooth: 5.0(>15m, without Obstruction) Chip: TPA3116D2(with AM Interference Suppression Function) Power Supply Voltage: 12V-8 ohm/12W(Left Channel)+12W(Right Channel), 4 ohm/20W+20W, 15V-8 ohm/18+18W, 4 ohm/30+30W, 19V-8 ohm/32+32W, 4 ohm/40+40W, 24V-8 ohm/38+38W, 4 ohm/50+50W Audio Input: Bluetooth+AUX+U Disk+Computer USB Sound Card(Plug and Play) Adaptation Speaker: 10-100W, 4-8Ω Channel Number: Left/Right Two Channels(Stereo) Bluetooth Name: Wuzhi Audio Protection Mechanism: DC detection, Over-voltage, Under-voltage, Overheating, Short Circuit Protection Adapter Power: 9-24V(High Voltage Recommended For High Power) Do Not Overvoltage, Small Ripple Factor Power Supply, 24V Battery Power Supply Not Allowed Size Details: Size: 6cm x 6cm x 2.9cm/2.36" x 2.36" x 1.14" (Approx.) Notes: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Tip: Only when the audio input is enough and the power supply/current is enough, there will be enough output power. The higher the power supply voltage, the higher the relative power, and speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the larger the horn's ohms, the smaller the relative sound power, please pay attention! Package Includes: 1 x power amplifier
