SYNC IN MULTI-ROUTER SYSTEMS
In a multi-rack system each router /
processing rack requires its own sync
connection. The router in each rack
provides sync over the network in turn
to the I/O boxes connected to it.
It is vitally important that all router /
processing racks on the same network
are locked to a sync derived and locked
from the same source. If any routers are
clocked by free running sync, or if they
are derived from different sources, both
network audio and communications will be
compromised.
Racks running on different syncs can
cause instability leading to the loss of I/O
and unreliable error messaging.
If sync is being distributed via equipment
such as regenerators / buffers, it is
important to ensure that they are all set to
lock to the correct input from the master
sync generator.
