Parameter Chip: TPA3116D2 (With AM interference supperession) With or Without Filter: Yes (Filtered sound is more round and clear ) Adaption Supply Voltage: 5-27V (Optional 9V/12V/15V/18V/24V, high power recommended high voltage) Speaker: 30W-200W, 4ohm-8ohm Number of Channels: Left and right stereo (Stereo) Version: 5.0 Transmission Distance: 15m (Without occlusion) Protection Mechanism: overheating, undervoltage, overheating, DC detection, short circuit protection Link: https://drive.google.com/open?id=1GxbZsYgzn3oSwQ9L4kp5pVKtGi6JuUoI Power Supply Voltage 12V--8ohm speaker / 12W(Left channel)+12W(Right channel), 4ohm speaker / 20W+20W; 15V--8ohms / 18W+18W, 4ohm / greater than 30W+30W; 19V--8ohms / 32W+32W, 4ohm / greater than 45W+45W; 24V--8ohms / 38W+38W, 4ohm / greater than 55W+55W. Note: The power switch on the board is the standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug the DC plug on the machine for a long time. Tip: To have enough output power if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound power.
