I seem to always have an underlying hum/static in the background of my mixer audio (Mackie ProFX8V2). It's not coming from any individual channel, and I use ground loop isolators already. I

I've included an audio source link below if anyone is willing to listen. It's -54db, and not too prominent. It's just something I'd like to get rid of if possible.

My fear is it's a power issue and I'd need a UPS Power Supply or maybe a Power Conditioner? I read an Amazon review that states the following:

Could that be my problem? Should I look for another mixer entirely etc.

Audio Gear:
  • Microphone - Shure SM7B
  • Mic Preamp - Cloudlifter CL-1
  • Headset - Audio-Technica ATH-M50X
  • Mixer - Mackie ProFX8V2
  • Compressor - Behringer MDX4600
Thanks for taking the time - and I apologize that it's not exactly an OBS problem.
