I have a home-made Raspberry Pi digital streamer, which uses the Airplay protocol. It streams from wifi to the Raspberry Pi and out over optical via a HiFiBerry hat. There is no analog conversion going on until the signal moves beyond the Raspberry Pi and the hat.
I also have a Berhinger DEQ2496 (Swiss army knife EQ, DAC, ADC, or digital only processor). Yesterday I decided to put my DEQ2496 in between my Raspberry Pi and my receiver, so that I could do Stupid Audio Tricks with it. In the past I have only used the DEQ2496 for headphone EQ and crossfeed—this was the first time I’ve used it with my stereo system. I’ve had it for about 15 years.
The first question is: The DEQ2496 says I am getting digital clipping based on the input signal when I stream at max volume over AirPlay via wifi from my iPad to my Raspberry Pi to the DEQ2496. When I back off one volume step from max on the iPad all the clipping is gone—we are at -2 or -3 dB from clipping at peaks. I am having a hard time even conceptualizing what this indicated digital clipping means or what I should do about it or if it’s real, etc. Could someone please help me understand this? I suppose I could always back off one notch down from streaming at max volume using airplay over WiFi from the iPad to the Raspberry Pi, if that’s what the Behringer is trying to tell me I should do.
The second question is (for those of you with experience with the DEQ2496): Can I use my DEQ2496 (which can generate pink noise) and a nice microphone for last-stage bass managememt, i.e., smoothing out the bass FR? I have two subwoofers crossed over via an A/V receiver. If so, how would I use the DEQ2496 for this type of bass managememt? By ear I’m quite happy with my bass response but of course I wonder if I can do better, as part of the hobby.
To anyone who generously expends the time and effort to help, thanks!!!
