DC 12V100W150W200W digital amplifier board

DC 12V100W digital amplifier board. The digital amplifier using DC power, small size and light weight. With stable performance, beautiful sound, signal to noise ratio, high efficiency, low temperature and other characteristics. Its functions whole plant can be designed according to the requirements of the development of new products, update products, saving the best matching product development cycle. Characteristic index: ????? High Efficiency:?? 93% ????? rated output power: 50W, 100W, 150W, 200W, 250W, 300W can be selected fixed resistance ?????? ?? Output: 4-16Ω ?????? ?? supply voltage:? DC 12V / 24V / 36V / 48V56V / 68V / 80V voltage can be selected according to the frequency required ?????? ??????? Width: 20Hz-20KHz ?????? letter ?? ?? noise ratio: 98--110 db ?????? ???? loss really ?? degree:?? 1KHz 0.1% 100w @ 8Ω input and output? Interface: DC input signal + - 12V 200mA Output Power Output Control Interface (equivalent switch) dimensions and weight: dimensions: 106x152x59mm Weight: 586 g Installation Notes: 1, 200W DC input cables need to use 2.5 square, otherwise Output power shortage. 2, the signal input cable, shielded cable required, otherwise it will cause damage to the power amplifier board self-excited! 3, the signal input is important to note + - pole, otherwise it will cause damage to the power amplifier board self-excited! 4, to provide the + -12V output, when not in use do not need to take.
