US $2.03/piece Item Description TDA7294 2.1 sound track power amplifier board 1, using a new laser dark word TDA7294. 2, the power filter using 6 63V3300UF Japan imported Panasonic capacitor, rectifier using 25A import rectifier flat bridge. 3, 1.6mm using PCB thick double-sided plate, 2 an ounce copper thickness, tin spraying process, to ensure that the size of the current through the performance of the good. 4, fever components assembly, the bass part from the two new BTL TDA7294 output, low pass filtering is in accordance with the home theater type frequency adjustable design (50-150HZ), strong power! Left and right channels were served by two TDA7294, input coupling capacitors using the German import 2.2UF WIMA coupling capacitor, the sound is more sweet! The board"s signal to noise ratio is also very high, ear close to the speaker can not hear the sound of the exchange! Is the best choice to upgrade the 2.1 power amplifier! 5, giving a fixed screw and mica plate, insulation gasket. The board is unworthy to radiator, need to install their own radiator (heat dissipation area of at least 200*80MM above, the bigger the better) side Ketong electric work! Working voltage: double 18-28V alternating current Lost power: 2X80W 160W bass cannon PCB board size: 218x98MM Potentiometer features: low frequency modulation - bass cannon volume - Left and right sound track volume - High pitched-Bass.
