100W200W300400W500W constant pressure with power digital amplifier board

The Division newly developed integrated digital amplifier with power components, fixed resistance, constant voltage while the output, with stable performance, beautiful sound, high signal to noise ratio, automatic protection, high efficiency, low temperature, no audio output transformer minimizes machine production costs, the features to meet the requirements of the whole plant, is to develop new products and update products, saving the best matching product development cycle. High efficiency performance index:? 93% output power:? 100W, 200W 300W 400W 500W select according to need constant voltage output power:? 100V 70V 60V fixed output resistance:? 8-16Ω supply voltage:? AC220V bandwidth:? 20Hz-20KHz ?? SNR: 98db distortion degree: ???? 1KHz 0.1% 100w @ 100V built-in automatic fan input and output interfaces: Signal input power output + - 12V 200mA output dimensions and weight:??? Housing material: Aluminum alloy dimensions: 232x136x63mm Weight: 1.36Kg Installation Notes: 1, the signal input cable, shielded cable required, otherwise it will cause damage to your amplifier board self-excited! 2, the signal input is important to note + - pole, otherwise it will cause damage to the power amplifier board self-excited! 3, to provide the LED display, DC + -12V output, when not in use do not need to take. 4, amplifier which is bridged, in the measurement, the signal ground and the amplifier ground can not be connected, otherwise, it will damage the amplifier board.
