The ADI-648 is a sixty-four channel format converter from MADI to ADAT and vice versa. MADI handles sixty-four channels of 24-bit audio at sampling frequencies up to 48kHz and thirty-two channels up to 96kHz. All channels are transferred across a single cable, using either a coaxial (BNC) or optical network cable. The ADAT channels are provided via eight TosLink optical inputs and outputs, respectively.
