Description
TDA7294 5.1 Amplifier Board Dual 18-24V AC BTL Output 5X80W+160W Subwoofer HI-FI Pure Power Amplifier Board
Product Description
The core IC is a high-power brand-new laser dark code TDA7294 integrated circuit developed by the famous European SGS-THOMSON STMicroelectronics in the 1990s. Quite courageous. It has completely changed the raw, cold, and hard tone of the previous successful playback, and is widely used in the HI-FI field. The design of the chip focuses on sound. It has high voltage resistance, low noise, low distortion, soft playback sound, and has short-circuit current and overheat protection functions.
Feature
Use original TDA7294. The power filter adopts four 50V10000UF Japanese original black diamond capacitors, and the rectification adopts 25A double rectifier flat bridge. PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. Special use of 3 relay speaker protection circuits to make your speakers safer. Fever component assembly, the subwoofer part is composed of two brand new TDA7294 BTL output, strong power! The other 5 channels are served by 5 pieces of TDA7294, and the input coupling capacitor adopts 2.2UF coupling capacitor, the sound is more sweet! The signal-to-noise ratio of the board is also extremely high, and no communication sound can be heard when the ear is close to the speaker! It is the best choice to upgrade 5.1 power amplifier!
