The AR-DR40 is a protective carrying case for Tascam DR40. The case has a clear vinyl display window that allows you to see and operate the recorder controls easily, without removing the recorder from the case. Velcro-lined openings provide access to cables and controls. In addition to the case,  a comfortable HB-15 shoulder strap is also included so the recorder can be worn conveniently around the neck or over the shoulder.
