Chapter 2: Operating Instructions
This chapter provides operating instructions to connect third-party devices supported
by the FC726.
2.1 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’s SDIF-2 Sync input or the FC726 will not lock. Turn the
MADI switch on the FC726 front panel to OFF (center position).
2.2 TDIF
1. Connect the TDIF adapter to the DB-50 connector(s) on the FC726’s rear panel.
2. Turn the MADI switch on the FC726 front panel to OFF (center position).
3. To avoid SRC, either lock the TDIF device to the MADI B device, or lock the
MADI B device to the TDIF device.
To lock the TDIF device to the MADI B device (i.e, Euphonix System 5 or R-1),
connect a word clock from the MADI device to the TDIF device’s 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’s Word
Sync Out to the MADI B device’s word clock input (i.e, on the Euphonix Studio
Hub). 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 TDIF device at
48 kHz. The TDIF and MADI B devices can each run on their own internal sample
clocks without additional sync signals.
