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

Euphonix Modular I/O Configuration Guide Product Description
10
Each audio backplane contains 32 passive stereo audio busses (64
total signal paths). Audio source and destination modules are
connected to audio busses via physical on-board jumpers or via
web-browser interface. Any audio buss may have multiple
destinations but only a single source. Different frames have
options to isolate audio busses in certain physical slot positions.
This enables higher signal densities.
•Control Buss
Each frame contains a single control buss. The control bus
interfaces to LAN via the FC972 Remote module. This enables
console control of mic preamps and web-browser configuration of
certain modules (other modules do not require any external control
and do not appear on the control bus). The FC972 may be
mounted in any frame slot and is assigned a unique IP address.
Up to 16 “controllable” modules may be fitted into a given frame
and each is assigned a unique ID via on-board switches.
•Sync Buss
Each frame contains a single sync buss that is shared by all
modules in the frame. Several modules may act as the frame sync
source such as the SY983 Sync (single and redundant
configurations available) any MADI module (lock to incoming MADI).
The sync source module(s) must be placed in any of the four red
“reserved” slots located in the rear-plane (slot positions 1-4).
These slots may also be used for other modules. If a MADI module
is used a sync source, the frame must not contain any SY983/982
modules for proper operation.
1.1.1 IO93 Modular I/O Frame
General Description
The IO93 is a 3RU double-sided frame with removable dual-
redundant PSUs capable of delivering 5v@12A of usable
power. The frame contains 19 rear-plane slots and 18 front-
plane slots for modules. Rear-plane slots 1-4 are “reserved”
for the sync source module(s). Other modules may be fitted
here also. Sync and control busses are shared by all slots in
the frame. Audio busses may be isolated between the front
and rear planes via an interconnect PCB located in the unit

interface)
General Description
The IO95 is a 3RU double-sided frame with removable dual-
redundant PSUs capable of delivering 5v@12A of usable
power. The frame contains 19 rear-plane slots and 18 front-
plane slots for modules. Rear-plane slots 1-4 are “reserved”
for the sync source module(s). Other modules may be fitted

the frame.

Euphonix Modular I/O Configuration Guide Product Description

For use as a local-side interface for redundant MADI-over-
Fiber, four rear-plane “positions” of 3-slots each are audio
isolated from the rest of the frame. These positions are as
follows: slots 8-10, slots 11-13, slots 14-16, and slots17-19.
Modules placed in these positions share the frames sync
and control busses.
The remaining 7 rear-plane slots (which includes the four
“reserved” slots) may be isolated from the front-plane via an
interconnect PCB located in the unit (configurable via DIP
switched, some disassembly required to access).

1.2 MADI, Control, and Sync modules
1.2.1 MM934/MM934opt MADI In/Out
General Description
The MM934 contains a single MADI I/O and optional multi-
mode fiber transceiver (MM934opt). The module features a
master sync mode that allows it to derive the master sync
source for the rack from its MADI input. MADI working
modes set via on-board switches determine how it connects
to the 32 stereo busses available on the backplane. All
settings are done from on-board switches.
Working modes (label from MADI perspective). See
Chapter 2 for cross reference between MADI I/O and audio
busses.

96k Operation:
In frames operating at 96k sample rate, only the first 28
signals in a MADI stream are available. In these cases, <32

with 28 MADI inputs and 28 MADI outputs at 96k.
Note: When used as the master sync source, the
MM934/MM934opt MADI In/Out should only be
removed from a frame after the frame has been
powered down. Possible damage may occur to some
I/O modules if the master sync source is removed
from a live frame.

operation. The module is typically placed in an IO94
Stagebox frame and interfaces to the console via a MM936
and MM934 pair placed in an IO95 local-side interface frame.
The module features a master sync mode that allows it to
lock a frame to its MADI input. Certain settings are done
from on-board switches such as device ID. Buss
configuration is accomplished using a flexible crosspoint
matrix configured via web-browser interface.
Note: When used as the master sync source, the
MM936 MADI In/Out should only be removed from a
frame after the frame has been powered down.
Possible damage may occur to some I/O modules if
the master sync source is removed from a live frame.
Connections, Power Consumption, Width, Weight
Redundant multi-mode fiber: 62.5/125µm, 1310nm, one
fiber strand per direction (SC x4), ~500 mA, 4HP. ~150g.
1.2.4 SY982 Sync (discontinued-replaced by the SY983 Sync)
General Description
The SY982 contains an internal clock and can lock to
external AES Sync, Word Clock, or Video signal. Internal
sample rates are 44.1k, 48k, 88.2k, and 96k. The module
features a sync redundancy mode which allows two modules,
designated master and slave, to be fitted into a rack. If the
master loses sync, the slave automatically takes over.
SY982 Sync module(s) must be fitted into any of the four
reserved slots on the rear-plane. All settings are done from
on-board switches.
Note: The SY982 Sync module should only be
removed from a frame after the frame has been

are used for certain settings including device ID. Web-
browser interface via FC972 Remote provides access to
module status and settings.
