Dimension D is one of the legendary Roland chorus effects. It’s unrivalled in the way it widens & spreads sounds across the stereo field. It’s been the secret weapon of mix engineers for years. There are plugin emulations available but nothing comes close to the real sound of a Dimension D

Describing the Dimension D as a chorus unit doesn’t really do it justice. It has the effect of widening sounds and putting them in stereo picture. It’s not a deep, chorusy device but a rather subtle effect that is smooth, warm and three-dimensional

Alog with my GML Massenburg equaliser, it’s one of the few things I’ve owned, sold, and regretted selling

“Rather than being a blatant effects unit, it falls more into the category of psychoacoustic processors”

“It is a spatial enhancer, not a traditional chorus”

“The Dimension D was a “subtle” chorus where you hear more of an added stereo dimensionality than typical chorus modulation per-se. Never heavy and swirling… it really adds something special to synth pads”

“i canĀ“t hear any modulation, the guitars are much wider and there is more space for the other stuff in the mix”

“The Dimension D or SDD320 is the absolute GREATEST CHORUS EVER MADE. 100% analog and 4 settings. You can press more than one at a time similar to an 1176”

“Its a chorus OR, when used subtley, a stereo widener. It works incredible on ANYTHING”

“Love the Dim D on bass!!!! I have to force myself to not use it all the time”

Inputs & outputs are balanced on XLR and unbalanced on jack sockets. Power input is 220 VAC with a short three-core cable to an IEC socket. UK or Euro Schuko power cable supplied on request
