Taidacent Dual 18-24VAC 2*80W+160W 25A Rectifier Bridge Home Audio Subwoofer Amplifier TDA7294 2.1 Channel Power Amplifier Board

Taidacent Dual 18-24VAC 2*80W+160W 25A Rectifier Bridge Home Audio Subwoofer Amplifier TDA7294 2.1 Channel Power Amplifier Board

Product details:

Using the famous European SGS-THOMSON STMicroelectronics in the 90's to destroy a field tube output of high power new laser word TDA7294 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

Power supply filter with 6 50V3300UF Nikon capacitor, rectifier with 25A imported 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.
 
The use of fully enclosed dust-proof potentiometer, more stable performance, more durable than the ordinary potentiometer!
 
Especially to add the current advanced UPC1237 speaker protection circuit, so that your speakers more secure.
 
Fever components assembled, subwoofer part of the two new TDA7294 composed of BTL output, low-pass filter is designed according to the home theater frequency adjustable (50-150HZ), power strong! Left and right channels were held by two TDA7294, the input coupling capacitor using German imports WIMA 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 the 2.1 amplifier!

Basic parameters:

 Potentiometer function: low frequency frequency adjustment, subwoofer volume. Left and right channel volume, treble, bass.
