Euphonix FC727 Format Converter Users Manual Introduction and Interface

1.1.3 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 FC727/726 uses a com-

mon 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 rear panel of the third-party device. These adapters are available separately

from Euphonix. In most cases, another cable is required to connect the adapter to the

third-party device. For example, a cable is required to connect the FC727 to a Pro Tools

computer just as it would be to connect to an 888-24 I/O unit. See Appendix A: Pinout

and Cable Specifications for detailed information.

1.1.4 Sample Rate Conversion

Digital audio devices have previously been required to use the same sample rate to op-

erate correctly together. The FC727/726 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 FC727/

726 detects different sample rates and automatically activates SRC.

Although the FC727/726’s SRC is the highest quality available, some users may

still require an unaltered, bit-for-bit copy of the data. In this case, connected devic-

es can be slaved to the same sample clock, which disables SRC automatically (you

can also disable SRC manually).
