Making Signal Connections
Local Signal Connections
Signal connections differ depending on the signal being managed and the backplane installed. Fol-
low the procedure for the type of signals being received or distributed:
• AES synchronous (both balanced and unbalanced). See AES Synchronous Signals on page 45.
• MADI synchronous (unbalanced). See MADI Synchronous Signals on page 47.
• Analog. See Analog Signals on page 49.
• Quad Mix. See Quad Mix on page 52.
AES Synchronous Signals
The NV7512 can route both balanced and unbalanced AES synchronous signals. Unbalanced sig-
nals are received and distributed through DIN 1.0/2.3 connections. Balanced signals are received
and distributed through DB25 connections. The coaxial connections are housed on backplanes
installed in the back plate. (See
Backplanes on page 12).
For unbalanced signals, the backplane contains 32 DIN 1.0/2.3 connections labeled ‘1’, ‘2’ and so
on up to ‘32’. For balanced signals, the backplane contains four DB25 connections labeled ‘1-4
Stereo’, ‘5-8 Stereo’, ‘9-12 Stereo’ and ‘13-16 Stereo’. The labels correspond to the signal numbers
assigned to signals passing through that connector. (See
Backplanes on page 12).
NVISION recommends using the 1855A Belden cable for DIN 1.0/2.3 connections, however, alter-
native cable choices are available. For more information, see the DIN 1.0/2.3 Coaxial Connectors
