Number of channels : 2.1 channels
Power amplifier chip:TDA7498E
(with AM interference suppression function)
Adapted power supply :DC 15~36V (less than 9V undervoltage protection) (the higher the voltage, the greater the output power)
Adapted speaker : 30-200W,4-8Ω Output power : Left and right channels ≤160W
Subwoofer ≤220W
Protection mechanism:overvoltage, undervoltage, overheating, DC detection, short circuit protection
Product size:145*126*28mm
Tip: Only when the audio input is sufficient and the power supply voltage/current is sufficient, can there be sufficient output power!!!
The higher the power supply voltage, the greater the output power, the smaller the horn impedance, and the greater the output power !!!
Please ensure that the power of the adapter power supply is greater than the actual working power of the amplifier !!!
