Can I just tell it I want to run 20db hot from 20htz to 50htz, then slowly drop off to flat at 125htz?
Normally when doing DSP work you'd want a mic and measuring software (REW) to find out how the signal is being affected by changes.
Also, of you want to use REW AutoEQ, you'll need to specify a Target Curve and have a measurement from your speaker. AutoEQ will then put together some advanced EQ modifications that you'd export in the format for NanoAVR.
Notice we've hardly talked about the NanoAVR up until this point. Whatever changes you make in the DSP, the NanoAVR doesn't care if it made your signal sound better or worse. It has no mic to figure out if your settings were good or bad...which is why you'd want to use a mic with REW software so you can see how your changes in the NanoAVR are affecting the output from your speakers.
Regarding types of changes, you can specify a peak (most popular), high shelf (upper freq), or low shelf. You can specify whether the change should be broad or very narrow and anywhere in between. A positive change will increase the signal while a negative value will reduce that freq range.
Hope that helps. By the way, you might be able to download the software and play with it without even having the device. You can make changes on your computer and then upload the configuration or if you stay connected, you can make changes in real-time.
