The EMI mastering console.
Looks like the link did not go to room 25 as i wished . Any studio experienced agoners out there ? What is a viable method other than a console ? sounds more expensive than preamps made for audiophiles .I have been looking at monitor volume controls from  Crane Song , Coleman , Grace Designs . ect ...
