The IsoPac E is a portable, large vocal/voice-over booth that can also function as an instrument isolation system. It consists of a six-section clear acrylic panel system (A5-6,) six 12" height extender panels (AX12,) dark grey SORBER absorption panels that can be arranged in several different combinations, and two double section SORBER baffles (S5-2) that form a "rear wall." A lid system and fan complete the kit.

The IsoPac E is easy to get in and out of. Since SORBER panels don't actually connect to the ClearSonic Panels, one can simply use an outside section of a SORBER system as a "door." The booth is not intended to be air tight or sound proof. It is recommend to leave air gaps on either side of the lid panels and above the S5-2 back units to allow for air exchange.

All SORBER products have a Class-A fire rating.
