I was a little surprised to see this old relic pop up on the "Products" page!
I'm not sure if this will work for many people running modern systems anymore (DX is dead), but it was actually a pretty good-sounding EQ/channel strip in its day. What I recall is that the controls are programmed terribly - they "pull" when you expect them to "push" - and I was forced to stop using it. Which is too bad, it had a nice high shelf and gentle compressor.
Not too much to add, apart from that. There are many, superior, free modern options for channel strips (not the least of which is Cubase 7's excellent new Channel Strips), so I would avoid this.
