Revision MM2006-1 X16 MADI Merge Unit
3.5.3 MADI Thru Mode
In addition to providing the MADI Merge facilities, the X16 also has
the ability of providing a Thru mode. This feature enables the oper-
ator to route up to four independent and complete optical MADI input
streams directly to the four MADI output pairs. This provides both op-
tical and coaxial MADI conversion, while also providing a two way
output split for each of the four MADI input streams.
MADI Thru Mode is selected from the front panel via the Processing
Mode switch.
3.5.4 Wordclock Synchronisation
The X16 is fitted with five wordclock BNC connectors for synchroni-
sation purposes.
■ One BNC providing Wordclock Master/Slave connectivity
Operation of the Wordclock Master/Slave BNC is controlled via the
front panel Wordclock switch.
Wordclock Master.
The internally generated wordclock conforms well within Grade 2
specifications (being +/- 3.5ppm).
The wordclock output circuitry driving this BNC connector is capable
of driving long cable lengths with minimum degradation of the word-
clock signal. This allows the X16 to be the system master reference
clock source, while also allowing connection to remote equipment,
such as digital consoles. These may be some distance away from
the M16/X16, if located stage-side for example.
