I have recently been shown this mixing trick (encoding) and am quite interested in obtaining a stereo setup of these units myself for mixing. Anyone know where these suckers can be found? I've heard of them selling around <$300 but can't find any out there now.

When I was a kid in this business, (not too long ago!), one of the coolest things was to be able to watch a big shot mixer do some cool trick on a mix and then later try it out myself. Having said that, I thought I'd start a thread about mixing TRICKS that are cool. I'll start.
