Euphonix System 5 Installation Guide

Power

Most of the System 5 console components have dual power entry connectors for redun-
dant power supplies. Euphonix recommends deriving power from two different sources
to maximize the failsafe capabilities. The best case is to connect one power supply to a
UPS (Uninterruptible Power Supply) and the other to a clean technical power source. If a
UPS is not used, the power supplies should be connected to separately protected clean
technical power circuits.

Sync

A high quality sample-clock source is required for many System 5 components. These
include the DF66 SuperCore, CO600 MADI Changeover Switch, and all MADI I/O.
Wordclock or AES Sync (DARS) may be used. In addition, video sync is required for the
serial machine control interface (housed in the System Computer) to enable proper syn-
chronization.
Euphonix has tested several digital sync generators and distribution amplifiers and can
supply these devices with the console. Contact a Euphonix sales representative for further
information.
Euphonix recommends the following guidelines:
•
Typically, Wordclock/AES Sync is derived via a converter from the facility's
master video sync reference. Never employ multiple video sync-to-sample-
clock conversions in a single system. Separately derived sample-clocks may
not be in-phase.
•
It is important to minimize the timing differences between signal paths to
avoid cumulative timing errors. Ideally, each distribution amplifier should be
fed directly from the master clock source.
•
Never loop sync signals through multiple MADI converters. In this way, ti-
ming errors will not accumulate and powering one converter down will not
cause loss of sync to others.
NOTE: Drawings in this installation guide show the use of Word Clock. However,
AES Sync (DARS) or Word Clock may be used.
