Euphonix FC726 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 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 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. See Appendix A: Pinout and Cable Specifications for detailed informa-

tion.

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 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 SRC.

Although the FC726’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 devices can

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

also disable SRC manually).
