SUMO is available with a full range of accessories and is easily compatible with FM systems and a variety of Direct Audio Input (DAI) devices. The special interlocking adaptor shoe (sometimes also referred to as a "boot") has been especially designed to prevent accessory loss and ensure full connectivity. This revolutionary shoe design creates a dependable and true locking connection with SUMO's battery compartment, not just a friction fit like most other systems. In addition, the shoe connection allows easy access to the battery compartment without removing the shoe.
