Introduction
The Euphonix FT730 FiberTran Fiberoptic Extender allows an ML530 Microphone/
Line preamplifier or MC524 Monitor Controller to be placed up to 3300 ft (1 km) away
from the processing core of a Euphonix digital console. The FT730 is always used in
pairs with one local unit at the control end and one remote unit at the far end connected
by up to 1 km of fiberoptic cable. Normally four fibers are used:
• One pair sends audio sync and control information to the remote end and re-
ceives status information back.
• The second pair sends and receives MADI.
The same device is used at both ends but their functionality differs: If a sync source is
connected (AES or word clock), it is a local unit; otherwise, the device looks for sync
on the sync fiber and, if found, behaves as a remote unit.
Front Panel
The front panel has LEDs that indicate the status of the power supplies, synchronization
activity, and the status of several other functions. Each group is discussed in the follow-
ing sections.

Power
The system has two power supplies for redundancy. A simple monitoring circuit checks
whether each supply is functioning within allowable limits and displays their status on
the PSU 1 and PSU 2 LEDs on the front panel. The information is also sent over the
fiber link to the remote end. The LEDs indicate the following status:
• Solid - Both power supplies are functioning normally.
• Flashing - Remote power supply has failed.
• Off - Local power supply has failed.
