Thanks mate
The four iMacs are for my new project called Institute for Audio Technical Studies (Center for Lydteknik, in Danish). Which is basically a fancy word for: I'm doing music production classes every Saturday from 12.00 - 15.00
I've been doing about 150 master classes each year for the last 6 years and I wanted to take it to the next level.
As a student you'll sit in front of an iMac running Logic Pro with an Apogee Duet sound card and Sennhesier HD595 headphones. Everything is connected via Remote Desktop to my main station so I can show & tell.
You can learn about equalizing, compression, production and mixing in general, mastering, etc. Apple have asked me to become an Authorized Apple Training Center too, and iMacs are perfect for that.
