Optional extras

FM compatibility and options
Sumo DM is compatible with all FM systems through an interlocking FM-7 Adaptor shoe. Users of Lexis can choose the dedicated LE-7 receiver, which is smaller, and which eliminates the need for an adaptor shoe.



Secure DAI connections
AP700 DAI adaptor shoes interlock securely into the battery door to allow devices such as MP3 or CD players to be attached. The DAI and FM adaptor shoes allow access to the battery without having to remove the shoe.



Tamper-resistant features
The tamper-resistant doors can be opened and closed for ON-OFF functionality. The volume control, with its clear numeric markings, can be disabled in the software to prevent accidental changes to the instrument.



Easy right & left identification
Red and blue plates provide easy identification of right and left instruments.


Two sizes of hooks
Sumo DM comes with a damped and an undamped earhook. A smaller hook for young children is also available as damped or undamped, for maximum gain and output.
