Constructed as a nested case system, both the inner and outer cases are made from 9MM multilayer plywood surfaced with black leather-grain fireproof laminate. The inner case is divided into two sections: a 4U space for equipment installation and an 8U section configured with four steel drawers. These drawers can be customized with foam inserts to securely store microphones and other gear. This design not only allows for convenient placement on console tabletops but also provides dual protection for valuable microphone amplifiers and equipment.
