WEILIANG B3
All aluminum alloy chassis, using the TI company&39;s latest high-performance TPA3116D2 power amplifier chip as the core, with the op-amp NE5532, better strength, aluminium radiator, with switch potentiometer, power socket is a standard of 5.5 * 2.5 mm, the same as the most laptop power supply, DC 8V to 25V wide working voltage, maximum output power of 100W.
The power supply of the circuit board is very important, the higher the voltage, the greater the current, the greater the output power, if you use a 12V 1A power supply, it can only drive a 3-4 inch speaker, but if you use a 19V 5A power supply, it can drive an 8-10 inch speaker.
Input voltage: DC 12V-24V.
Output power: maximum 100W.
Signal input: 3.5mm.
Size: 88*68*37mm.
Net weight: 0.25kg.
Weight after packing: 0.4kg.
