Chapter 1: Introduction to the FC726
The FC726 is a compact, 2U, digital-audio format converter that translates back and forth between MADI (Multichannel Audio
Digital Interface) and the digital audio formats listed in the table below. AES/EBU outputs are always available, regardless of the
formats being translated. The FC726 performs the highest quality sample-rate conversion (SRC) on all channels that require it.
The FC726 includes the following features:
• Can apply different format conversion and/or SRC to each bank of eight channels.
• Automatically applies SRC when necessary but can be manually disabled.
• Performs format conversion and SRC on more channels (56) than other devices.
• Each of the 56 channels is bidirectional.
• Supports 24-bit audio at a 96 kHz sample rate.
• Maintains compatibility with older devices by offering 16- or 20-bit dithering and supporting 96 kHz legacy standards.

Chapter 1: Introduction to the FC726 1
Basic Concepts
Channels and Banks
The FC726 can convert 56 digital audio channels in two directions simultaneously (simultaneous bidirectional conversion)
with any of the supported devices. The 56 channels are divided into seven banks, each with eight channels. Each bank
may be connected to a different third-party device running at
a different sample rate (such as Tascam DA-88 on channels
1–8, ADAT on 9–16, and AES/EBU on 40–48).
Signal Flow
Since 56 channels can be converted bidirectionally, signal
routing can become confusing. These simple rules should help
clarify the signal flow:
• Audio arriving at the MADI B Input is sent out the
Format A Output.
• Audio arriving at the Format A connectors is sent out the
MADI B Output.
• The AES outputs always mirror the Format A Output.
Sample Rate Conversion
Digital audio devices have previously been required to use the
same sample rate to operate correctly together. The FC726 removes this limitation by allowing many sample rates simultaneously. For example, by using the common DB-50 connectors, each eight-channel bank can operate at its own sample
rate. Furthermore, the FC726 detects different sample rates
and automatically activates Sample Rate Conversion (SRC).
Although the FC726 SRC is the highest quality available, some
users may still require an unaltered, bit-for-bit copy of the
data. In this case, connected devices can be slaved to the same
sample clock, which disables SRC automatically (you can also
disable SRC manually).
Format A Inputs
Three connectors can be used by third-party inputs: the common DB-50 connectors, the MADI A Inputs, and the DB-25
AES connectors. The appropriate signal is chosen according to
the following rules:
• If the MADI switch is ON, the MADI input is used for all 56
channels.
• If the MADI switch is OFF, either the common DB-50 or AES
signals are used in eight-channel banks.
• If only one connector is in use, that format is selected.
• If both are connected, the common DB-50 signal takes
precedence.
Format A Adapters
To create a compact 2U device with maximum flexibility, the
FC726 uses a common DB-50 connector for all third-party formats. An adapter is required to convert from the DB-50 connector to the company’s own connector. The adapter is not
intended to be the connecting cable; it simply adapts the common DB-50 connector so it behaves like the back panel of the
third-party device. These adapters are available separately
from Avid. In most cases, another cable is required to connect
the adapter to the third-party device. See Appendix A, “Pinout
and Cable Specifications” for detailed information.

FC726 front panel (center detail)
1. MADI Switch
This three-position switch selects whether MADI is used for
the Format A Input and the characteristics of the MADI signal.
ON-STD Selects the standard MADI settings used by Avid
(sample rate = frame rate).
OFF Selects the common DB-50 connectors and ignores the
Format A MADI inputs. Use this setting with SDIF, TDIF,
ProDigi, ADAT, or AES devices.
ON-ALT Selects MADI running at sample rate = 96 kHz, frame
rate = 48 kHz.
2. SRC ENABLE Button
This button lights when the FC726 detects different sample
rates on the A and B formats and SRC is being used. Press the
button when lit to turn off SRC. The button flashes if SRC is
needed but has been disabled by the user. Press the button
again to reset the automatic SRC detection circuitry.
When a device first locks to the FC726, the button may occasionally light to indicate SRC is necess ary when it is not. Press
the button twice to reset the FC726 automatic SRC detection
circuitry. SRC is not needed if the button does not light.
Chapter 2: FC726 Features 5
3. FORMAT A Input Indicator LEDs
65
7
Each eight-channel bank has seven LEDs to indicate the format attached to the Format A Input; only one of these LEDs
can be lit at a time. The LED lights dimly yellow if an adapter
is attached but the FC726 has not locked; the LED lights bright
yellow when the FC726 locks to the device.
The bottom SRC LED functions independently of the first
seven. It lights red if the FC726 has detected that SRC is required on that bank; it flashes red if SRC is required but has
been disabled by the user.
4. OUTPUT BIT DEPTH Select Switch
For each eight-channel bank, this switch sets the bit depth for
the signal output to the Format A device. When set to 24, all
24 bits are transferred from the MADI input to the Format A
output device without dithering. When set to 20 or 16, the signal is dithered to the selected number of bits before being output to the Format A device.
This switch affects the Format A output only; it has
no effect on the Format B MADI audio output.
FC726 front panel (right detal)
5. FORMAT B Sample Rate LEDs
These LEDs indicate the Format B sample rate. If the rate is not
44.1, 48, or 96 kHz (±3%), the CUSTOM LED lights. Since the
FC726 supports SRC, Format A may operate at several sample
rates that are not indicated by individual LEDs.
6. FORMAT B Sync Source LEDs
These LEDs show the Format B sync source. The blue button
below the AUTO LED manually cycles the sync source sequentially from AUTO to AES, WORD, MADI, and FORMAT A.
When set to AUTO, the FC726 accepts the first sync signal detected with the following priority: AES, WORD, MADI, and
FORMAT A. For example, if MADI and Format A sync are both
present, the selected source will be MADI because it is higher
in the priority list.
7. Power Switch
This switch turns power to the FC726 on or off.

format to connect the third-party devices. See “Format A
Adapters” on page 2.
5. Service DB-9 Jack
This jack connects to a PC serial port to upgrade the FC726
firmware.
3. Format A AES Connectors
Seven DB-25 connectors connect AES devices to the FC726.
Each connector provides eight bidirectional channels (four
AES pairs). To connect to the third-party devices, use a
DB-25-to-XLR breakout cable available from Avid.
Do not connect anything to the Service DB-9 jack unless
instructed to do so by Avid technical support.
Do not use DB-25-to-XLR breakout cables made by
other companies because the pin numbering may be
incompatible. See Appendix A, “Pinout and Cable
Specifications” for specific cable information.
Chapter 2: FC726 Features 7
6. DIP Switches
7. Format A AES Sync In
These eight DIP switches (numbered 1–8 from left to right) set
various modes on the FC726. Switches 3–5 and 7 are not currently implemented.
Switch #1 Bidirectional mode
Flip this switch when converting between third-party formats
using one FC726.
Switch #2 MADI MERGE
When set to MADI MERGE (down), Format B MADI Input 1
channels 1–24 are merged with Format B MADI Input 2 channels 1–28 and Format B MADI Input 1 channels 25–28 to form
a single 56-channel input stream. Format B MADI Output 1
sends channels 1–56 and Format B MADI Output 2 sends
channels 25–56 followed by 1–24 from the third-party inputs.
Switch #6 AES MASTER/SLAVE
When set to SLAVE (up), the Format A AES outputs lock to
their corresponding AES inputs. Within each bank, all AES
outputs operate at the sample rate of the lowest-numbered,
locked AES input. For example, if the first bank (channels 1–8)
has a 44.1 kHz AES signal connected to inputs 1–2 and a 48
kHz input connected to inputs 5–6, then AES output channels
1–8 will all run at 44.1 kHz. If AES inputs are not present on a
bank, Format A will get sample clock from the Format B Sync
input. If sync is not present, Format A will then lock to the
Format B Sync Input.
Connect an AES sync signal to this XLR connector to synchronize the Format A MADI signal. According to the AES specification, the AES sync signal must use the same sample rate as
the incoming MADI signal to operate correctly.
It is possible, but not recommended, to connect a
MADI signal without using a corresponding sync
signal. Providing an AES or Word sync results in
lower jitter and should be used whenever possible.
8. SDIF-2 or SLAVE CLK IN
This connector can receive either an SDIF or slave clock sync
signal. The FC726 automatically detects which signal type has
been connected.
An SDIF device must send a word sync signal to this connector
to properly connect to the FC726.
9. SLAVE CLK OUT
If Slave Clk In has a valid sync signal, it is passed through to
Slave Clk Out. If Slave Clk In does not have a valid sync signal,
the lowest numbered bank that is locked and in use is selected
as the clock source.
When set to MASTER (down), Format A AES outputs get sample clock from the Format A Sync input. If Format A sync is
not present, the Format A AES outputs will then lock to the
Format B Sync Input.
Switch #8 AES STEREO/AES MONO
Set this switch to AES Stereo (up) for the normal configuration
where each AES signal contains two discreet channels. If the
sample rate is above 52 kHz (such as 88.2 or 96 kHz), and the
AES signal connected to the FC726 implements two-wire AES
(also referred to as mono mode AES), set the switch to AES
Mono (down). This setting treats each AES signal as a single
channel with a frame rate running at half its sample rate. For
example, a 96 kHz two-wire AES signal runs at 48 kHz by using
the left channel for the even samples and the right channel for
the odd samples. This switch affects both the AES inputs and
outputs.

SDIF-2
SDIF-2 is a 24-channel format with inputs and outputs on separate DB-50 connectors. The FC726 SDIF-2 adapter has three
DB-50 connectors, one for each eight-channel bank (labeled
1–8, 9–16, 17–24) but they may be connected to any FC726
bank. This allows routing the channels in eight-channel
groups.
The SDIF-2 format requires connecting an external word clock
on a BNC cable from the SDIF device to the FC726 SDIF-2 Sync
input or the FC726 will not lock. Turn the MADI switch on the
FC726 front panel to OFF (center position).
TDIF
1 Connect the TDIF adapter to the DB-50 connector(s) on the

2 Turn the MADI switch on the FC726 front panel to OFF

3 To avoid SRC, either lock the TDIF device to the MADI B de-
vice, or lock the MADI B device to the TDIF device:
• To lock the TDIF device to the MADI B device (i.e, System
5 or R-1), connect a word clock from the MADI device to
the TDIF device Word Sync In. The Format B Word Sync
Out on the FC726 may be used if no other word clock
output is available. Set the TDIF device to slave to its
word clock input.
• To lock the MADI B device to the TDIF device, connect
the TDIF device Word Sync Out to the MADI B device
word clock input. Set the MADI B device to slave to its
word clock input.
4 SRC is required if the MADI B device runs at 96 kHz and the
TD IF d evice a t 4 8 kHz. The T DIF and MAD I B devic e s can ea c h
run on their own internal sample clocks without additional
sync signals.
ADAT
1 Connect the ADAT adapter to the DB-50 ports on the FC726
back panel.
2 Connect the ADAT optical cables to the ADAT back panel
and to the adapter’s optical input and output.
3 Turn the MADI switch on the FC726 front panel to OFF
(center position).
4 Set the ADAT adapter switch to the same setting used on the
ADAT front panel.
• If multiple slaved ADATs are connected, this switch
should match the setting of the first (master) ADAT. Always use the ADAT INT setting to perform SRC.
The switch on the ADAT adapter has two settings to tell the
FC726 how to synchronize to the ADAT optical device(s). Its
setting depends on whether the connected ADAT optical device slaves to the FC726 or runs on its own internal clock:
ADAT INT The ADAT runs on its own internal clock (INT refers
to internal).
ADAT DIG The ADAT slaves to its optical (digital) inputs (DIG
refers to digital). Since the optical input comes from the
FC726, this setting slaves the ADAT to the FC726.
ProDigi
ProDigi (PD) is a 16-channel format with inputs and outputs
on separate DB-50 connectors. The FC726 PD adapter has two
DB-50 connectors, one for each eight-channel bank (labeled
1–8 and 9–16). They may be connected to any bank on the
FC726 with one restriction: the connector labeled 1–8 must be
connected to a lower-numbered bank than the 9–16 connector. This allows the channels to be routed in eight-channel
groups. Turn the MADI switch on the FC726 front panel to
OFF (center position).
Chapter 3: Operating Instructions 11
AES
Each of the 28 AES inputs can run at a different sample rate.
The following rules clarify how the sample rate of the AES output signal is derived:
• Within each bank, all AES outputs operate at the sample
rate of the lowest-numbered AES input that is locked. For
example, if the first bank (channels 1–8) has a 44.1 kHz
AES signal connected to inputs 1/2 and a 48 kHz input
connected to inputs 5/6, then AES output channels 1–8
all run at 44.1 kHz.
• If AES inputs are not present on a bank, but another Format A device (i.e., TDIF) is connected and locked, the AES
outputs run at the Format A sample rate for that bank.
• If a bank has neither AES inputs nor a third-party device,
the AES outputs run at the Format B sample rate.
• If the MADI switch is On, the AES outputs run at the Format A MADI sample rate.
Furthermore, these rules can be modified by DIP switch #6:
AES Master/Slave.
• If the switch is set to Master (up; the default position),
the rules stated above apply.
• If the switch is set to Slave (down), the AES outputs never
run at the AES input sample rate. Instead, they follow the
rules above assuming an AES input is not present. This
mode should be used to lock the connected AES device to
the AES output of the FC726.
Converting Between Formats
Using Two Units (56 Bidirectional Channels)
1 Connect Format B MADI Input of the first FC726 to the For-
mat B MADI Output of the second FC726.
2 Connect Format B MADI Input of the second FC726 to the
Format B MADI Output of the first FC726.
3 At 48 kHz, use the In1 and Out1 connectors; at 96 kHz, use
In1 and Out1 and In2 and Out2 connectors.
4 Connect the third-party devices as described in their sec-
tions of this chapter.
5 Connect a common sync source to both FC726s and all at-
tached third-party devices.
6 Do not allow both FC726s to attempt to lock to each other’s
MADI input.
Using One Unit (24 Bidirectional Channels)
1 Move DIP switch #1 to the down position.
2 Loop Format B MADI Out 2 to Format B MADI In 1.
3 If there is no sync on Format B, select Format A as the sync
source from the front panel.
4 Connect the third-party I/O devices.
The conversion is from third-party I/O channels 1–24 to channels 25–48. As always, all third-party inputs are still converted
to Format B MADI Out 1.
For example, to convert 24 channels of ADAT to 24 channels
TDIF (DA88), connect ADAT to third-party channels 1–24,
connect the three DA88s to channels 25–48 and follow the
steps above.
