Chapter 1: Product Description 
Euphonix Modular I/O is designed to add a new level of flexibility in I/O 
configuration to the Euphonix range of audio converters. The Modular I/O 
system offers several types of frames that can be fitted with a variety of I/O 
modules. This allows frames to be customized to exactly meet client 
requirements. For interface to the console, all signals are converted to MADI. 
Audio formats supported are remote control preamp, line level analog, AES/EBU, 
Dolby encoder/decoder, and HD/SD embedder/de-embedder. Other modules 
provide sync and remote control interface. Redundant multimode fiber 
connection for stageboxes is also supported. 
The descriptions that follow are divided into the following groups of components 
•  Modular I/O Frames 
•  MADI, Control and Sync Modules 
•  Audio I/O Modules 
Note: The component settings descriptions are not all-inclusive. Only the 
most relevant settings for product understanding have been included here. 
See the manufacturer’s data sheets for a complete listing of all options 
and switch settings. 
1.1 Modular I/O Frames 
Euphonix offers several frame types, each specified for particular 
applications. Characteristics of the frames can be categorized as follows: 
•  Backplane Space 
Module widths are either 1 slot or 2 slots (termed “4HP” per slot). 
Single sided frames contain a 19 slot (76HP) “rear-plane”. Double-
sided frames contain a 19 slot “rear-plane” and an 18 slot (72HP) 
“front-plane”. 
•  Power Supplies 
All frames contain dual-redundant power supplies. However, 
supply power capacity and mounting (built-in vs. removable) 
depends on the frame type. 
•  Audio Busses
