Recommended Sync Distribution Method - Euphonix System 5 Installation Manual

Euphonix System 5 Installation Guide
Synchronization Details
It is important to minimize the timing differences between signal paths to avoid cumulative
timing errors. It is good system engineering practice to send all system components their
sync signals from one source. Sync signals should not be looped and each distribution am-
plifier should be fed directly from the master clock source. The following guidelines are
provided to illustrate the correct sync distribution. Word clock or AES/EBU sync may be
used but word clock may be preferred due to its lower cabling and labor costs.
Studios with Existing Digital Master Clock and Sync Distribution
•
Clock jitter should be less than 0.025 UI (AES3-1992 (r1997)).
•
One additional D/A output is required for each system component.
•
Cable runs from the master clock to the distribution amps should be equal in
length (AES11-1997, 5.4).
Installations Without an Existing Digital Master Clock
•
Use one of the Euphonix recommended sync generators (see next page).
•
These sync generators may be set to internal or gen-locked to a video reference.
•
Use a Euphonix recommended distribution amp (see next page) to feed all sys-
tem components and additional studio devices directly.
•
Cable runs from the master clock to the distribution amps should be equal in
length (AES11-1997, 5.4)
