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 can´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
