Euphonix FC726 Format Converter Users Manual Introduction and Interface
10
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.
The audio remains entirely in the digital domain so it suffers no degradation due to D/A
and A/D conversion.
1.1 Basic Concepts
1.1.1 Channels and Banks
The FC726 can convert 56 digital audio channels in two directions simultaneously (si-
multaneous bidirectional conversion) with any of the supported devices. The 56 channels
are divided into seven banks, each with eight channels. Each bank may be connected to
a different third-party device running at a different sample rate (i.e., Tascam DA-88 on
channels 1–8, ADAT on 9–16, and AES/EBU on 40–48).
1.1.2 Signal Flow
Since 56 channels can be converted bidirectionally, signal routing can become confusing.
These simple rules should help clarify the signal flow:
• Audio arriving at the MADI B Input is sent out the Format A Output.
• Audio arriving at the Format A connectors is sent out the MADI B Output.
• The AES outputs always mirror the Format A Output.
