Abstract
The present invention is directed to a digital mixer that selectively provides audio signal processing functions to a user depending on the authority granted to the user's log-in credentials. The preferred embodiment of the digital mixer includes a mounting unit for removably mounting a storage medium, a detector for detecting the mounting or removal of the storage medium, a determining portion for determining whether a user key is stored in the mounted storage medium, and a control portion that, upon the determining portion confirming that the mounted storage medium includes a user key, causes the digital mixer to display a log-on screen for a specific user who is associated with the stored user key. In accordance with the preferred embodiment, the digital mixer automatically logs out the user upon detecting that the storage medium is removed from the digital mixer.
