The 3I-0907-MC3 holds three mics in a very compact case and is part of the 3I Waterproof Series of cases. 3I series injection molded waterproof cases are constructed of ultra high-strength polypropylene copolymer resin and feature a gasketed, waterproof and airtight, submersible design (IP67) that is resistant to corrosion and impact damage. Its continuous molded-in hinge, patented "trigger release" latch system, comfortable, snap-down rubber over-molded cushion grip handle, secure stacking, and automatic ambient pressure equalization valve (MIL-STD-648C) all contribute to its military grade design. The 3i-0907-MC3 allows 3 mics to be stored horizontally. Each microphone cutout measures 1.5” wide by 6.75” long with two perforated removable foam pieces, one located on each end allowing microphone sizes up to 8.5” in length. By removing the perforated foam piece near the grill of the microphone you can change the shape from being round to square. This will accommodate other popular hand held microphones with square style grills such as the Sennheiser and Electro Voice mics. The 3I-0907-MC3 case measures 9” x 7” x 4” deep and is the most compact 3-mic case on the market. The case has convoluted foam in the lid for a compression fit and is covered by SKB's unconditional lifetime warranty.
