EMI Problem Solving
Hello,
I've just built a new rig (detailed below post). It's suffering from what I assume is EMI. Whenever I drag my mouse around or play back in Pro Tools I'm getting digital noise / clicking. I've tried isolating with seperate power, each part of the chain one-by-one to find where it's coming from but so far no luck. Everything is powered by the same Furman PL-8CE conditioner (I know this isn't ideal, but it's what I have to work with). Even isolating all computer parts from the audio parts the issue is still happening. Looking for advice. Here's the rig: *Everything is connected to the Furman PL-8CE: 2018 Mac mini UAD Apollo 8 UAD Apollo Twin UAD Apollo Satellite Octo + Quad Avid Artist Mix Razer Core X w 5700XT OWC 4M2 Synology NAS LG 4K Display 2x Genelec 8040 monitors Netgear Network Switch AC Infinity T7 + T9 blowers

Re: EMI Problem Solving
Have you isolated down to just the Mini, a monitor screen, single audio interface and speakers (or headphones)? Actually I'd go so far as skipping the interface/monitors and plug the cans directly into the Mini. Get down to as minimal system as you can. I know there are a couple of plugins that give off digital noise when mousing but not PT alone.
The latter gives me an idea - move all third party plugins to the unused plugins folder and test. |

Re: EMI Problem Solving
Oh great, a long travel for those made in Finland workhorses. I have 5 of them connected to Genelec 7060B sub, on a live rig have pair of 8050's without sub.

Re: EMI Problem Solving
Is the mouse a wireless mouse? Can you borrow a wired mouse to test? I ran a wireless mouse for a short time, but the noise it induced in guitar or bass(when self-recording) was awful. My Logitech wired mouse is dead quiet(its worth a try).

Re: EMI Problem Solving
I had a clients rig with a similar issue. Turned out to be the thunderbolt connection to the apollo. Instead of getting a new better shielded tb cable, he just lifted the ground on the cables running from the monitor out of the Apollo to his monitors.
