the clock from the incoming MADI data stream. Once these two items are
correctly selected, the input status bar displays whether there are errors or
clock slippage. The input status display is also echoed at the top of the main
screen if an error or any digital slippage occurs. Any clock errors are noted in
the error display area of the main screen. The Clock Error Display can be
cleared using the STOP button. The information area of the main screen will
indicate when the Reference clock is missing or when a digital signal slip
occurs.
Analogue: Normally set to "Off" can either insert or replace any 8 of the
digital channels in the MADI data stream. This will normally only be used if
you are using a console with Legacy (56 channel) MADI and want to use
separate mic pre-amps to capture the audience or ambience of the venue
without taking it through the console
Output Setup... allows you to control whether the output format is Legacy
(56 channel) or full MADI-X (64 channel). You can also set up the wordclock
BNC connector to output wordclock rather than be an input. It is also
possible to have a separate reference clock for the output MADI stream and
this too is set here.

This section contains the most frequently adjusted parameters.
Reference Clock
This very important item determines where the digital sample clock is
derived from. The options include
extracting the clock from the MADI input
stream; using the external word clock BNC
connector; less often, the S/PDIF external
clock from the RCA (Phono) socket on the
rear panel, or on rare occasions, clocking
the whole system from the internal
reference oscillator.
