I am planning to design a digital pre-amp using SigmaDSP, this project is still under concept study.
The design spec for input and output would be as following::
- 1 Stereo audio input
- 1 Mic input
- 1 Stereo audio output + 1 subwoofer
Other rotary controls
- Rotary control for Tripple
- Rotary control for Bass
- Rotary control for Middle
- Rotary control for Balance
- For Mic:
- Rotary control for Echo
- Rotary control for Delay
- Rotary control for Feedback
I am thinking to use ADAU1701 in this design. However, I am not sure if it is good enough to deal with 1 stereo audio input + 1 mic input.
Another worry is rotary controls for several parameters. It is mentioned in the datasheet that there are only 4 Aux ADCs available for the rotary control. How can I do to achieve additional rotary control?
Afterall, is ADAU1701 suitable to be considered in the project above?
