Everyone is looking for that elusive extra dimension to their mix, and Roland’s latest unit claims to deliver it right out of the box. Dave Lockwood assesses dimensional expansion for himself. The SDX330 Dimensional Expander is the latest addition to Roland’s RSS‑based Dimensional series, joining the SRV330 Reverb (reviewed SOS August) and the SDE330 (SOS October 1993). RSS (Roland Sound Space) is a processing system which utilises psychoacoustic properties to create the illusion of sounds originating in a three‑dimensional space, rather than just being placed across the traditional frontal soundstage. There are, of course, a number of well known simple techniques for making the stereo image wider than the loudspeaker placement would seem to allow. These usually employ a little of the opposite channel’s signal being fed anti‑phase into the other side. But RSS goes well beyond this and, in a well set up demonstration, really can cause signals to appear to be originating from behind the listener’s head!
