Audio DSP Project

I have designed an audio DSP with ADAU1701 from Analog Devices.
It will be used both for radio amateur use and for stereo systems.


ADAU1701 has two analogue inputs and 4 analogue outputs.
These are connected to the RCA connectors. Outputs are connected
through operation amplifiers.On the front there are three buttons
and a small screen. These can be used to set the DSP program.



On the bottom is the DSP and the Arduino.
I2C connects Arduino, the display and DSP.
