In this video, we have made a 5.1 Channel Amplifier Board using TDA7294 Audio Amplifier ICs. On a single board, there's a 5.1 channel amplifier circuit using 7x IC's (TDA7294) out of which 5 IC's are used single ended (90w each) and 2 IC's are used in bridged configuration (180w) for subwoofer channel. Each channel has it's own input and output. This board has very heavy heatsink that is recommended for cooling of these 7 IC's and also There's a FAN mounted onto the PCB with it's own regulated 12V power supply circuit. This board also has inbuilt Rectifier dual supply with 22000uF/63V capacitor on each rail and with fuse protection. The board requires 20-0-20VAC to 24-0-24 VAC Transformer to operate optimally.
