Homebuild 200W stereo amplifier with computer controlled power and volume using TDA7294
current status
Programming
I made a software application that resides in the system tray and can turn the amplifier on/off by clicking on it
It also handles the volume from the amplifier
Interface
the interface is very simple, that was also the meaning of my project
Digital Power switch
the power switch is also very simple, just a relay and a very small power supply
Digital Volume Control
The volume control is fully electronic but has low distortion
Power Supply
power supply is probably the most expensive part. But it is needed for a good sound
Amplifier
The amplifier is based on the high quality TDA 7294 mono amplifier IC and is again easy to build
Speakers
To know which speakers I use is not really relevant, but it will show some pictures of the final result
