Chapter 1: System 5 Overview

This Euphonix System 5 is a fully-featured digital audio mixing system. The system is
highly configurable -- options include a scalable control surface with application-specific
controls (for example, dual joysticks with a film monitor panel), a scalable DSP mix engine,
a flexible I/O system, an integrated MADI router, a serial machine control interface, and
GPIO.
These options allow the System 5 to be configured for virtually any audio mixing applica-
tions, including large-scale film production, on-air broadcast, post-production, and music.

Theory of Operation

The System 5's primary components communicate via a 100Base-T star network. These
components include the DF66 SuperCore mix engine, all control surface modules, the
SC264 System Computer, and the CO600 MADI Changeover Switch used in broadcast
redundancy configurations. In addition, TCP/IP-controlled devices such as the modular
remote preamps also communicate through this network.
Secondary peripheral devices include the ML530 Mic/Line Interface and the MC524 Mon-
itor Interface. These devices are connected to the SC264 System Computer and commu-
nicate via the Euphonix TCC serial protocol. The SC264 also houses the GPIO and serial
machine control interface.
All Euphonix I/O devices interface via MADI. I/O devices connect directly to the DF66
SuperCore or to the CO600 MADI Changeover Switch in broadcast redundancy configura-
tions.
The following sections describe important aspects of system operation and configuration.

Digital Signal Processing (DSP)

The DF66 SuperCore performs all audio processing in the System 5, including dyna-
mics, EQ, mix busses, aux sends, and monitor busses. The unit can be fitted with up to
six SP662 DSP cards with each card providing four MADI I/Os. DSP is allocated using
factory-supplied Mixer Model files which provide different numbers of busses and chan-
nels.
The number of DF66 DSP cards required in a system depends on the number of logical
channels desired, for example: a mono source uses one logical channel, a stereo source
uses two, and a 7.1 source uses eight.
In broadcast redundancy configurations, two identical DF66 SuperCores operate in parallel,
one as primary and the other as backup. Each connects to the CO600 MADI Changeover
