Active Bi-Amplifier Board || TDA7294 || Inbuilt 2 way Active Crossover || DIY || HINDI || IXA

Описание: In this video, We have built a Bi-Amp board using TDA7294 Audio Amplifier IC. Bi-Amping is a technique where we have two different amplifier sections, one for woofer (low-mid frequencies) and second for tweeter (high frequencies) by using an Active 2 way crossover that filters the frequency band and send to each of the amplifier section. The cut off frequency can be adjusted by changes few values of resistors and capacitor in the circuit.

In Bi-Amping , the Stereo would mean a total of 4 Amplifiers (2 for left channel and 2 for right channel).
The board we built in this video has single IC (TDA7294) for High frequency section and 2 ICs (TDA7294) in bridged configuration for Low frequency section.
The Board also has inbuilt Rectifier Dual Supply using 4 capacitors (4700/35V each). The Board has inbuilt 2 way Active crossover using Opamps (JRC5532D or NE5532).
The Board Requires 20-0-20 VAC to operate optimally, however 24-0-24 VAC can be used to achieve more power and the Maximum voltage for this board is 27-0-27VAC. Remember, It is recommended to use 8 ohm load for this board to get stable performance.
