I know this is a little confusing.
However, I believe, "dimensions" is equivalent to the basic measurements of the chassis rectangular perimeters (ie. width X height X depth).
While "gross dimensions" [may] include the basic chassis perimeter measurements, however, with the addition of the extended measurments of the front-panel control's (ie. knobs, dial's, switch's, etc.,..), rear-panel termination components (ie. binding-post's, RCA connector's, etc.,..), and the chassis feet. All these create a larger rectangle.
Usually the manufacturer (ie. NAD) will specify "shipping weight", or "shipping dimensions", when referring to unit as packed in box or carton.
