  • Page 13: Chapter 1: Introduction And Interface

    The FC726 performs the highest quality sample-rate conversion (SRC) on all channels that require it. The FC726 sets a new standard for format conversion devices with the following features: • Can apply different format conversion and/or SRC to each bank of eight channels.

  • Page 14: Basic Concepts

    Euphonix FC726 Format Converter Users Manual Introduction and Interface The utility and power of the FC726 is exhibited by transferring digital audio between incompatible devices: • Mixdown on a Euphonix System 5 digital console at 24-bit 96 kHz with source material from a ProDigi or Sony tape machine at 48 kHz (automatic SRC).

  • Page 15: Format A Inputs

    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.

  • Page 16: Front Panel

    Introduction and Interface Front Panel The FC726’s front panel is shown in Figure 1-1. Enlarged sections of the front panel 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 17 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.

  • Page 18: Fc726 Front Panel (Right)

    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.

  • Page 21 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 con- nect to the FC726.

  • Page 22: Fc726 Rear Panel (Right)

    Figure 1-6 FC726 rear panel (right) 10. Format B MADI IN 1 and MADI OUT 1 These BNC connectors are used to interface with a MADI device. (Euphonix users can connect these to a Studio Hub, MA703, or AM713) At 48 kHz, the Format B MADI In 1 and MADI Out1 connectors provide 56 24-bit audio channels.
  • Page 23 Euphonix FC726 Format Converter Users Manual Introduction and Interface NOTE: 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.

  • Page 25: Chapter 2: Operating Instructions

    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.

  • Page 26: Adat

    (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).

  • Page 27: Aes

    Euphonix FC726 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.
