Abstract
Apparatuses, systems and methods are presented which provide for a musical instrument direct box combined with a musical instrument tuner which may be phantom powered from an external audio system. In some embodiments, an apparatus is presented that includes a direct box (DI) module and a musical instrument tuner module coupled to the DI module. The instrument tuner module may be phantom powered based on connection to a remote system geographically distinct from the apparatus, and configured to measure the pitch of the instrument signal and mute the instrument signal simultaneously. In some example embodiments, the apparatus may also include a tuning transformer coupled to the musical instrument tuner module and the DI module, the tuning transformer configured to galvanically isolate a ground domain of the instrument signal from a ground domain of the remote system while the musical instrument tuner module measures the pitch of the musical instrument signal.
