    Chapter 1: Introduction to the FC726 The FC726 is a compact, 2U, digital-audio format converter that translates back and forth between MADI (Multichannel Audio Digital Interface) and the digital audio formats listed in the table below. AES/EBU outputs are always available, regardless of the formats being translated.

    For example, by using the common DB-50 connec- The FC726 can convert 56 digital audio channels in two direc- tors, each eight-channel bank can operate at its own sample tions simultaneously (simultaneous bidirectional conversion) rate.
