Product overview
The GRACE DESIGN E401 30cm Bar is the 30 cm horizontal Spacebar stereo bar with precision distance markings: the bar of the SB-30, interchangeable with the E406 66 cm bar in the field.
The horizontal bar comes in two sizes: 30 cm for the SB-30 and 66 cm for the SB-66, and the two are interchangeable in the field. On the 30 cm bar the microphone holder spacing ranges from 7 cm to 26 cm. The mic holders are secured to the bar by position lock nuts; loosening them lets the holders slide side to side, set with 5 mm precision on the ruler on the front of the bar. The ruler is for reference: the actual capsule spacing is measured with a tape measure or ruler.
