The Porta Brace CAR-3AUD audio equipment carrying case is designed to transport audio equipment such as a recorder, mixer, Portabrace AR or MXC bag, wireless microphones, batteries, headphones and harness. The bag is made of 1000 denier Cordura nylon with solid steel rings. It also features reversed zippers and a slip-not waterproof bottom panel to improve durability and water resistance. The bag includes front and back pockets for documents, cables and frequency cards. Two side pockets can be used to store additional batteries, tapes, small tools and other cables. The interior of the bag is made of copper-coloured Veltex to provide visual contrast with the bag's interior contents. The interior layout of the bag can be reconfigured using a movable horizontal separator, a 15 cm by 23 cm padded pocket, and a set of three 15 cm Piggin' cords. A suede shoulder strap and built-in carrying handles are also included.
