Artefacts using DSP of A8

I received my A8 last week and generally happy with it. One important feature is the DSP function as I want to use it to EQ out the room mode I have in the low frequency (between 30Hz and 50Hz). I tried the parametric EQ to filter out these frequency. Unfortunately the DSP always gives me weird artefacts when using it. Independent if I use apple music to listen to songs or on my installed hard drive. Did any experienced these problems? Is there a fix for it?

Thanks allot for your help!

 

What are the parameters of the filters you are using and how did you ascertain them?

Hi Keith, I think I have found the problem. I set the DSP gain to 0 db and even though I only used attentuading EQs it clipped. With overall gain set to -1 it works now.

 

Excellent, I believe Eversolo recommends keeping at -5dB.
