Cabling
Reference signals can be routed using loop-thru daisy-chains. The signal
originates at a generator. It can then either be directly fed into the Concerto
matrix, or routed through a control frame or a matrix frame before con-
necting to Concerto. In
two Video References and an AES Refer-
ence are routed to the Concerto frame. Video Reference 1 is terminated at
the Concerto frame. Video Reference 2 continues from Concerto to the
7500WB and on to the 7500NB before being terminated at the end of the
bus. The AES Audio Reference is routed to the 7500NB where it is termi-
nated. All references used must be terminated at the end of the bus. Unused
reference connectors do not need to be terminated.
Note
If Concerto is configured with an Audio Module, an AES Audio Reference
must be present. In an Audio Expansion Set both matrices have to use the
same reference.
