Description
TDA7293 5.1 Channel Amplifier Board 5X80W+160W Subwoofer Relay Speaker Protector HIFI Stereo Audio Power Amplifier
Product Description
The core IC of the board uses the prestigious SGS-THOMSON microelectronics company in the 90's to destroy a field tube output of the new power laser new word TDA7293 integrated circuit. Quite bile. Completely changed the previous integrated amplifier amplifier, cold, hard sound, widely used in HI-FI field. The design of the chip to focus on the sound. With high pressure, low noise, low distortion, replay sound soft and resistant, and short circuit current and overheating protection
Using the original TDA7293.
Power supply filter using four 50V10000UF Japanese original black King Kong capacitor, rectifier with 25A double rectifier bridge.
PCB with 1.6mm thick double-sided sheet, 2.0 oz thick copper, tin spray the whole process to ensure that the size of the current through the performance of good.
In particular, the use of three relay speakers to protect the circuit, so that your speaker more secure.
Component assembly, subwoofer part of the two new TDA7293 composed of BTL output, power strong! The other 5-channel, respectively, by the five TDA7293 as the input coupling capacitor with 2.2UF coupling capacitor, the sound more sweet! Board of the signal to noise ratio is also very high, the ears close to the speaker can not hear the exchange of sound! Is the best choice for upgrading 5.1 power amplifier!
