TDA7293 is Europe\'s famous SGS-THOMSON ST Microelectronics in the 1990s to destroy a field of high-power IC tube output . Quite bile taste. Completely changed the previous integrated amplifier raw, cold , hard sound, widely used in HI-FI fields. The chip is designed to focus on the tone . Has a high voltage , low noise, low distortion, sound soft Naiting . The power amplifier board is 2 × 80W front and rear dual -channel integrated amplifier board level . Product Details Using genuine original TDA7293 and LC75342. Interstage coupling capacitor top WIMA capacitors using 2.2UF, electrolytic capacitors used in Taiwan brand signals the main loop , the main filter capacitor using gold NOVER capacity 2 × 10000UF, using flat bridge rectifier 25A and above , to ensure strong support for a steady stream of power . Resistor selection of rings metal resistance , the main circuit employs a precision of ± 1% metal film resistors rings , ensure the machine a good signal to noise ratio . 1.6mm thick sheet using double-sided PCB , 2.0 oz copper thickness , HASL whole process to ensure that the size of the current through the good performance . PCB -class quality . Using current advanced C1237 BTL speaker protection circuit, effectively eliminating open, shut down the impact sound and DC output protection features that make your speakers more secure.
