Chapter 1: Introduction to the FT730
The 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 an Avd Pro Series 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 receives status information back.
About This Guide
This guide provides a basic overview of FT730 features and
functionality.
For complete instructions on connecting and configuring
your system, see the System 5 Installation Guide.
Conventions Used in This Guide
• 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.
System Requirements and

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 following sections.

FT730 front panel (detail)
1. 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.
2. Sync
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.
3. Status
TCC Indicates TCC data activity.
Loop Indicates that the TCC/Sync fiber loop is complete and
the time of flight has been calculated.
MADI IN Indicates that a MADI signal is present on the 75-W
BNC MADI In and also on the Fiber TX connector.
MADI OUT Indicates that a MADI signal is present on the 75-W
BNC MADI Out and also on the Fiber RX connector.
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.

1. AES/SYNC IN (female XLR or BNC), WORD IN (BNC)
Connect this port to a digital sync reference (local unit only).
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.
2. AES/SYNC OUT (male XLR or BNC), WORD OUT (BNC)
Connect one of these ports to the digital sync reference input
of any device receiving MADI at the remote unit. Only one
output connection (XLR or BNC) should be used at a time.
3. RETIMED AES/SYNC OUT (male XLR), RETIMED WORD
OUT (BNC)
Connect one of these ports to the digital sync reference input
of any device sending MADI from the remote unit back to the
local unit. See Synchronization for Distances Over 800 ft (250
m) on page 13 for more information about these outputs.

• Connect TCC IN to TCC control port at local unit.
4. MADI IN (BNC)
MADI connection for signal being transmitted over fiber.
• 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.
5. MADI OUT (BNC)
MADI connection for signal being received from fiber.
2. FIBER SYNC/TCC TX/RX (ST Optical Connector)
Connects local and remote units. Connect local RX and TX to
remote TX and RX, respectively. Both connections are required for proper operation.
3. FIBER MADI TX/RX (ST Optical Connector)
Connects local and remote units. Connect local RX and TX to
remote TX and RX, respectively. A single connection can be
used if MADI signals are only required for one direction.

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-W coaxial cable. There are two important synchronization issues:
• The MADI signal’s transmitted frame start time must be
within 5% of the sample period time determined by the synchronizing signal.
This requirement is usually met by the circuit design using
the distributed synchronization signal.
• The received frame start time must be within ±25% of the
sample period reference time.
This requirement is governed by physics: it is the time of
flight (delay time) difference between the sample start
and the start of the frame. The speed of light
(299,792,458 m/s) and the propagation speed of the
transmission medium govern this delay time.
Transmission mediums, such as fiber and coaxial cable, have
propagation speeds in the range 60–70% of the speed of light.
This does not present a problem when MADI and the synchronization signal are sent together to a destination, such as a
MA703. The problem manifests when MADI is used to return
data from a source such as an AM713, where the delay time
difference for the MADI and synchronization signals exceeds
the received frame start time requirement (±25% of the sample period reference time).
The FT730 has two types of synchronization outputs:
AES/Sync or Word Out Used for devices receiving MADI at the
remote end. These outputs are used if the signal meets the criteria stated in the first bullet above.
Retimed AES or Retimed Word Sync Used for devices transmitting MADI to the local end. The control/sync fiber pair is used
to measure at the local end by comparing the local sync timing with that returned from the remote end. This number is
sent to the remote end where the timing is adjusted in sixteenth frame increments to keep it within the operational requirements stated in the second bullet above.
8 FT730 Guide
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). For distances longer than 6500 ft
(2000 m), single mode fiber (sometimes called monomode) fiber is used. Multimode fiber has a typical core diameter of
50–100 mm with a refractive index that is graded or stepped.
It allows the use of inexpensive LED light sources, and connector alignment and coupling is less critical than for single
mode fiber. This translates into lower connection and electronics costs and consequently lower overall system costs. The
FT730 uses 62.5/125 mm multimode fiber with ST connectors.
