Euphonix FC727 Format Converter Users Manual Chapter 1: Introduction and Interface The Euphonix FC727/726 is a compact, 2U, digital-audio format converter that translates 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, regardless of the formats being translated. The FC727/726 performs the highest quality sample-rate conversion (SRC) on all channels that require it.
Euphonix FC727 Format Converter Users Manual Introduction and Interface The utility and power of the FC727/726 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). • 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.
Euphonix FC727 Format Converter Users Manual 1.1.3 Introduction and Interface 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.
Euphonix FC727 Format Converter Users Manual 1.2 Introduction and Interface Front Panel The FC727/726’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.
Euphonix FC727 Format Converter Users Manual 1. Introduction and Interface MADI Switch 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. Use this setting with SDIF, TDIF, ProDigi, Pro Tools, ADAT, or AES devices.
Euphonix FC727 Format Converter Users Manual Introduction and Interface ❺ ❻ ❼ Figure 1-3 FC727/726 front panel (right) 5. FORMAT B Sample Rate LEDs 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 FC727/726 supports SRC, Format A may operate at several sample rates that are not indicated by individual LEDs. 6. FORMAT B Sync Source LEDs These LEDs shows Format B’s sync source.
Euphonix FC727 Format Converter Users Manual 1.3 Introduction and Interface Rear Panel The FC727/726’s rear panel is shown in Figure 1-4. Enlarged sections of the rear panel are shown in Figure 1-5 and Figure 1-6; the numbers in the figures correspond to the numbered items below describing that feature.
Euphonix FC727 Format Converter Users Manual 3. Introduction and Interface Format A AES Connectors 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.
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. For example, if the first bank (channels 1– 8) has a 44.1 kHz AES signal connected to inputs 1/2 and a 48 kHz input connected to inputs 5/6, then AES output channels 1–8 will all run at 44.1 kHz.
Euphonix FC727 Format Converter Users Manual Introduction and Interface A slave clock is a sync signal that runs at 256 times the sample rate. This is most commonly implemented in Pro Tools systems and is also referred to as a superclock. Pro Tools users may optionally connect the slave clock output from another Digidesign Audio Interface or Synchronization unit (i.e., 888-24) to the Slave Clk In connector to synchronize both devices. 9.
Euphonix FC727 Format Converter Users Manual Introduction and Interface 11. 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).
Euphonix FC727 Format Converter Users Manual Chapter 2: Operating Instructions This chapter provides operating instructions to connect third-party devices supported by the FC727/726. 2.1 Pro Tools 1. Shut down the computer running Pro Tools and the FC727. 2. Attach the Pro Tools adapters to the DB-50 connectors on the rear panel of the FC727 for the desired channels. 3. 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. 4.
Euphonix FC727 Format Converter Users Manual Operating Instructions 12. Press the Recalibrate Inputs button in the Hardware Setup dialog. After making any changes in the Hardware Setup dialog, you must press the Recalibrate Inputs button. 13. Press OK and you are ready to begin. You should now be able to make bidirectional transfers from a MADI device to Pro Tools. The Format B MADI audio input is transferred to the Pro Tools workstation.
Euphonix FC727 Format Converter Users Manual 2.4 Operating Instructions ADAT 1. Connect the ADAT adapter to the DB-50 ports on the FC727/726 rear panel. 2. Connect the ADAT optical cables to the ADAT rear panel and to the adapter’s optical input and output. 3. Turn the MADI switch on the FC727/726 front panel to OFF (center position). 4. Set the ADAT adapter switch to the same setting used on the ADAT front panel.
Euphonix FC727 Format Converter Users Manual 2.6 Operating Instructions AES 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. For example, if the first bank (channels 1–8) has a 44.
Euphonix FC727 Format Converter Users Manual 2.7.2 Operating Instructions Using One Unit (24 Bidirectional Channels) 1. Move dip switch #1 to the down position. 2. Loop Format B MADI Out 2 to Format B MADI In 1. 3. If there is no sync on Format B, select Format A as the sync source from the front panel. 4. Connect the third-party I/O devices. The conversion is from third-party I/O channels 1–24 to channels 25–48. As always, all third-party inputs are still converted to Format B MADI Out 1.
