Multiple preset
Hello, I'm doing an audio application with ADAU1701, and i would like to know (it this is possible) how i can, through just one external 3-position switch, access to one of three presets (being these presets three predetermined equalizations). If it's not possible with just one switch, which is the most suitable solution to achieve it?
Thank you.

I have forgotten to say that each of three settings, includes not only the setting in the equalizer, but also the settings in a compressor (block "RMS detect") and the settings in a block "Standard Clip". So in short, three different presets containing three blocks of settings in each and just one switch to access to them.
It's possible to toggle through EQ settings using an index-selectable filter block. There are several kinds that you can use. More details are available here: http://www.analog.com/static/imported-files/application_notes/AN-951.pdf
There are no index-selectable compressor or clipper algorithms, so you'll have to create three seperate paths for those and use an index-selectable demultiplexer to select one of the three outputs.
