Optional: I64 MADI Card for ADI-8 QS
The I64 MADI Card extends the QS with a 64-Channel MADI input and output and a sophisticated digital patch mode.
The card has an optical and a coaxial MADI input, which is switched automatically according to where a valid input signal is detected. This ensures full redundancy by immediately changing to the other input in case of signal loss. Coaxial and optical output operate in parallel, delivering the same data.
MADI can be used as an optional clock source (Clock section, OPTN), as signal source of the DA-converter, target of the AD-converter, and as digital thru. Since each QS converts only 8 channels, up to 56 channels can be passed through. This technique is used to serially cascade several QS converters. Incoming MADI data is passed through unchanged, only one block of eight channels is replaced. This allows up to 8 devices to be connected serially, with all 64 combined channels available at the last device's MADI output. When multiple devices are connected serially, the function Delay Compensation removes sample offsets between the units.
The QS can also be remote controlled via MADI, and send/receive MIDI data via MADI.
Additionally the i64 card enables a digital patch mode, that allows free routing of all I/Os based on blocks of 8 channels (needs i64 MADI card with Sync LEDs and firmware 3.x or up). In this mode, the 8 analog channels, AES, ADAT input 1 and 2, and 8 x MADI are available as input sources for the same number of outputs. The unit then works as digital format converter, rebuilds a MADI signal from various sources, inserts, converts and much more at the same time. Please read the QS manual for more detailed information.
