Regulatory and Safety Notices FCC Notice Part 15 of the Federal Communication Commission Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference free radio frequency spectrum. Many electronic devices produce RF energy incidental to their intended purpose. These rules place electronic equipment into two classes, A and B, depending on the intended use. Class A devices are those that may be expected to be installed in a business or commercial environment.
Modifications The FCC requires the user to be notified that any changes or modifications made to Avid hardware that are not expressly approved by Avid Technology may void the user’s authority to operate the equipment. Cables Connections to Avid hardware must be made with shielded cables with metallic RFI/EMI connector hoods in order to maintain compliance with FCC Rules and Regulations. PRODUCTS WITH MULTIPLE POWER INPUTS: WARNING: Each power input is intended to be connected to a separate branch circuit.

Euphonix FC726 Format Converter Users Manual Chapter 1: Introduction and Interface The Euphonix FC726 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 FC726 performs the highest quality sample-rate conversion (SRC) on all channels that require it.
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). • Mixdown on a Euphonix System 5 digital console from a audio workstation. • Transfer tracks from a Tascam DA-88, Sony 3348, or Alesis ADAT to a Euphonix R-1.
Euphonix FC726 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 FC726 Format Converter Users Manual 1.2 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.
Euphonix FC726 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, ADAT, or AES devices.

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. 6. FORMAT B Sync Source LEDs These LEDs shows Format B’s sync source.
Euphonix FC726 Format Converter Users Manual 1.3 Introduction and Interface Rear Panel The FC726’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 FC726 Format Converter Users Manual 3. Introduction and Interface Format A AES Connectors Seven DB-25 connectors connect AES devices to the FC726. 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 FC726 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 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. 13. Format B AES SYNC THRU This connector outputs a copy of the Format B AES Sync In signal. 14. Format B WORD SYNC IN Connect a word sync signal to this BNC connector to synchronize the Format B MADI signal.
Euphonix FC726 Format Converter Users Manual Chapter 2: Operating Instructions This chapter provides operating instructions to connect third-party devices supported by the FC726. 2.1 SDIF-2 SDIF-2 is a 24-channel format with inputs and outputs on separate DB-50 connectors. The FC726 SDIF-2 adapter has three DB-50 connectors, one for each eight-channel bank (labeled 1–8, 9–16, 17–24) but they may be connected to any FC726 bank. This allows routing the channels in eight-channel groups.
Euphonix FC726 Format Converter Users Manual 2.3 Operating Instructions ADAT 1. Connect the ADAT adapter to the DB-50 ports on the FC726 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 FC726 front panel to OFF (center position). 4. Set the ADAT adapter switch to the same setting used on the ADAT front panel.
Euphonix FC726 Format Converter Users Manual 2.5 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 FC726 Format Converter Users Manual Operating Instructions 2.6 Converting Between Third-Party Formats 2.6.1 Using Two Units (56 Bidirectional Channels) 1. Connect Format B MADI Input of the first FC726 to the Format B MADI Output of the second FC726. 2. Connect Format B MADI Input of the second FC726 to the Format B MADI Output of the first FC726. 3. At 48 kHz, use the In1 and Out1 connectors; at 96 kHz, use In1 and Out1 and In2 and Out2 connectors. 4.
