IMPORTANT SAFETY INSTRUCTIONS The lighting flash with arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electrical shock to persons. The exclamation point within an equilateral triangle, is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.
13) Unplug this apparatus during lightning storms or when unused for long periods of time. 14) Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

Euphonix FT730 FiberTran Fiberoptic Extender Operation Manual 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.
Euphonix FT730 FiberTran Fiberoptic Extender Operation Manual Sync 2 • Remote - The unit is locked to sync coming from the local unit over the fiber link. • Word - The unit is locked to sync on the word clock sync input. • AES - The unit is locked to sync on the AES sync input. If the unit is locked to Word or AES sync, it is designated as the local unit and sends digital sync to the remote unit over the fiber link. Status 3 • TCC - Indicates TCC data activity.

Selection for XLR or BNC input is done using two internal jumpers shown in Figure 4. The unit is shipped with the jumpers set for the XLR input.

Connect TCC OUT to TCC control port at remote unit. Because the same unit is used at both ends, each has a TCC IN and a TCC OUT connector. However, only the TCC IN is intended to be used at the local end and the TCC OUT at the remote end.

Euphonix FT730 FiberTran Fiberoptic Extender Operation Manual Technical Reference Synchronization for Distances Over 800 ft (250 m) MADI utilizes a polarity-free, serial NRZI (non-return-to-zero inverted) protocol with encoding at 125 Mbit/s (±100 ppm). Sample timing is controlled independently by distributing a master synchronization signal. Originally, the transmission medium was 75-Ω coaxial cable.
Euphonix FT730 FiberTran Fiberoptic Extender Operation Manual Single Mode vs. Multimode Fiber Optic Cable In optical fiber technology, multimode fiber is optical fiber that is designed to carry multiple light rays (modes) concurrently. Each mode is carried at a slightly different reflection angle within the optical fiber core. Multimode fiber transmission is used for relatively short distances (less than 6500 ft/2000 m) because the modes tend to disperse over longer lengths (modal dispersion).
