  • Page 9: Chapter 1: Introduction And Interface

    Euphonix FC727 Format Converter Users Manual Chapter 1: Introduction and Interface The Euphonix FC727/726 is a compact, 2U, digital-audio format converter that trans- lates back and forth between MADI (Multichannel Audio Digital Interface) and the digital audio formats listed in Table 1-1. AES/EBU outputs are always available, re- gardless of the formats being translated.

    Mixdown on a Euphonix System 5 digital console from a ProTools workstation. • Transfer tracks from a Tascam DA-88, Sony 3348, or Alesis ADAT to a Euphonix R-1. The audio remains entirely in the digital domain so it suffers no degradation due to D/A and A/D conversion.

  • Page 11: Format A Inputs

    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.

    Euphonix FC727 Format Converter Users Manual Introduction and Interface Front Panel The FC727/726’s front panel is shown in Figure 1-1. Enlarged sections of the front pan- el are shown in Figure 1-2 and Figure 1-3; the numbers in the figures correspond to the numbered items below describing that feature.
  • Page 13 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 Euphonix (sample rate = frame rate). OFF: Selects the common DB-50 connectors and ignores the Format A MADI inputs.

Enlarged sections of the rear pan- el are shown in Figure 1-5 and Figure 1-6; the numbers in the figures correspond to the numbered items below describing that feature.
  • Page 16 Seven DB-25 connectors connect AES devices to the FC727/726. Each connector provides eight bidirectional channels (four AES pairs). To connect to the third-party devices, use the DB-25-to-XLR breakout cable available from Euphonix. NOTE: 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.
  • Page 17 Euphonix FC727 Format Converter Users Manual Introduction and Interface 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.

Format B MADI IN 2 and MADI OUT 2 At 96 kHz, the Format B MADI In 2and Out 2 connectors provide 28 additional 24-bit audio channels (29–56). At 48 kHz, Format B MADI In 2 is ignored and Format B MADI Out 2 carries the same audio as Format B MADI Out 1 but with the channel numbering re- versed: Format A channels 29–56 are output on Format B MADI Out 2 chan-...

    Attach the Pro Tools adapters to the DB-50 connectors on the rear panel of the FC727 for the desired channels. Connect the Euphonix device, such as the System 5 or R-1, to the FORMAT B BNC jacks using the MADI and AES sync cables.

  • Page 22: Sdif-2

    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.

  • Page 24: Aes

    Euphonix FC727 Format Converter Users Manual Operating Instructions 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.
