Part I: Introduction to Modular I/O

Chapter 1: Introduction 7
Chapter 1: Introduction
The Avid Modular I/O system adds flexibility to configuring System 5 audio converters. Three frame types can be fitted with
a variety of I/O modules to meet client requirements. Frame controller, Sync, MADI, Analog Mic/Line, AES/EBU, De-Embedder,
and Dolby modules are available. The table below lists all modules in their categories.
This chapter includes overviews of each frame and how to choose a frame. See each frame’s chapter for installation and other
technical details.
Frame Specification
A Modular I/O configuration comprises modules selected to perform specific functions, and fitted to frames that accommodate
their sync, control, and I/O requirements. Before choosing, installing, or servicing a Modular I/O frame, consider the following
criteria.
Master Sync Source
Each frame must have a master audio sync source module for each sync zone, typically an SY983 Sync HD module. However,
several other I/O modules with a Master mode can be used instead, but not in conjunction with an SY983.
IO93 Double-Sided and IO94 Stagebox frames consist of a single sync zone. The master sync source module must be positioned
in one of four red sync source slots in the rear plane. The IO95 Multi-Zone frame contains five isolated sync zones. Each zone in
use requires its own master sync source module.

To avoid damaging analog circuits, install a master sync source module in a red reserved slot before applying AC power.

Modular I/O Configuration Guide8
Control Configuration
Each frame must be fitted with an FC972 Remote to externally configure all modules (except analog line in/out and WC984) and
control mic preamps remotely using a web browser or console. Install only one FC972 per frame and up to two SY983s (for re-
dundant operation, differentiated by Master/Slave setting).
Frame and Module Addresses
A Module's system ID consists of the Frame ID + module CAN ID. The Frame ID is determined by the FC972’s IP Address/Sub-
net/Host Address. The FC972 must be assigned a unique IP Address based on the frame’s role within the system. A CAN ID must
be set for each externally controllable module. The AD914 Remote Mic Preamp has 16 CAN ID settings available, whereas most
other modules have 32.
The FC972 and SY983 have default module CAN IDs that do not interfere with those of other modules. The internal CAN bus
must be terminated once per frame, either on the FC972 or SY983.
Using the CAN Address switches on the FC972 or SY983 is an older method of setting the Frame ID. An explicit CAN Address must
be set only when employing a hardware CAN-BUS remote controller to configure frames. In System 5, the Frame ID is set with
the FC972's IP Address for configuration using a web browser interface. CAN Address switches on the FC972 and SY983 must be
set to their non-active default values as described in their sections.
Frame Space
Frames have module slots in one or two backplanes. A module requires either one or two slots. Frames with two backplanes have
a front and rear plane. Make sure there is enough physical space in the frame for the specified modules. Each frame’s section in
this guide lists the required space per frame.
Power
Each module is powered by the frame’s +5 VDC rail. Power draw of the modules fitted in the frame must not exceed the frame’s
PSU capabilities. Power consumption for each module and power capability per frame is listed in each section of this guide.
Audio Busses
The Modular I/O backplanes are passive and all frame audio routing is set on the modules: Source audio is assigned to a bus routed
to a number of destinations. Each Modular I/O backplane contains 32 audio busses (S1–S32).
All I/O modules provide a 2CH mode (two audio channels per bus). Many modules also feature an 8CH mode (eight audio chan-
nels per bus). Source and destination modules must be set to the same mode.
Some frames consist of multiple audio zones that decouple the audio busses between different frame sections. This supports higher
signal densities per frame.

Chapter 1: Introduction 9
IO93 Double-Sided Frame
The IO93 Double-Sided Frame is a 3RU frame with redundant PSU and two backplanes. Master sync source module(s) must be in-
stalled in one (or two) of the four red slots in the rear plane near the power outlet before applying AC power. Spare red slots may
be used for other modules.
Top view of IO93 frame layout with red slots reserved for Master sync source modules
IO93 Frame Parameters
Master Sync
Source
The IO93 frame consists of one sync zone that requires one master sync source. This is typically an SY983 Sync HD
module or two SY983s configured in redundant sync mode.
Another I/O module with Master mode may be used as an alternate master sync source, but not with an SY983.
Control
Configuration
Each IO93 must be fitted with an FC972 Remote to control mic preamps remotely and externally configure all modules
(except analog line in/out and WC984) remotely using a web browser. Install only one FC972 in a frame.
Frame Space The IO93 frame consists of a front plane with 18 module slots, and a rear plane with 19 module slots.
Power The IO93 frame contains dual-redundant PSUs: 13 A @ 5 VDC.
Audio Busses Each of the two backplanes has 32 audio busses that can be linked or split between backplanes using internal DIP
switches. Depending on the configuration of the modules fitted, each bus can function in 2CH or 8CH mode.

Modular I/O Configuration Guide10
IO94 Stagebox Frame
The IO94 Stagebox Frame is a 3RU frame with redundant PSU and a single backplane. It is ideally suited for stagebox applications
and local I/O. Master sync source module(s) must be installed in one (or two) of the four red slots in the rear plane near the power
outlet before applying AC power. Spare red slots may be used for other modules.
Redundant MADI-over-Fiber Configurations
The IO94 Frame’s size and power are ideal for stagebox applications in which a MADI I/O module in Master mode serves as the
master sync source. This lets the frame lock to incoming MADI without connecting a separate sync cable to the stagebox.
The MM935 MADI I/O (coaxial I/O) is useful for shorter distances. The MM936 MADI I/O (redundant multi-mode fiber) is useful
for longer connections. The MM936 auto-switches between fibers if either fails. Multi-mode fiber can be easily converted to sin-
gle-mode using third-party products, thus letting standard SMPTE camera cables connect to the stagebox.

IO94 Frame Parameters
Master Sync
Source
The IO94 Frame consists of one sync zone and requires a single master sync source, typically an SY983 Sync HD module
or two SY983s configured in redundant sync mode.
Another I/O module with Master mode may be used as an alternate master sync source, but not with an SY983.
Control
Configuration
The IO94 Frame must be fitted with an FC972 Remote to control mic preamps remotely and configure externally controlled
modules using a web browser. Install only one FC972 in the frame in any position.
Frame Space The IO94 Frame has one backplane with 19 module slots.
Power The IO94 frame contains dual-redundant PSUs: 20 A @ 5 VDC.
Audio Busses The backplane has 32 audio busses each of which may be used in 2CH or 8CH mode, depending on the configuration of
the frame’s modules.
To use the MM936 MADI I/O (redundant fiber) in a stagebox, the redundant fiber must be converted to coaxial MADI to
connect to the console. An MM936+MM935 may be fitted in a console-side frame to accomplish this conversion. Alternatively,
if fiber auto-switching is not required, third-party MADI fiber-to-coaxial converters are available.

Chapter 1: Introduction 11
IO95 Multi-Zone Frame
The IO95 Multi-Zone is a 3RU frame with redundant PSU and two backplanes. The frame is divided into five discrete audio/sync
zones. The IO95 accommodates applications that use multiple I/O streams, each referenced to a separate sync source.
For example, several Dolby-E encoder/decoders can be fitted into one IO95, each in its own audio/sync zone and referenced to
separate sync sources. The audio is then fed into a central zone (using AES/EBU with SRC decoupling) where they are routed into
a single MADI stream.

IO95 Frame Parameters
Master Sync
Source
The IO95 frame consists of five discrete sync zones. Each zone in use requires its own master sync source, typically an
SY983 Sync HD module or two SY983s configured in redundant sync mode.
Another I/O module with Master mode may serve as a master sync source, but not with an SY983 in the same zone.
Master sync source module(s) can be installed in any slot in a zone.
Control
Configuration
The IO95 frame must be fitted with an FC972 Remote to remotely control mic preamps and configure externally controlled
modules using a web browser. One FC972 may be fitted in any position within the frame.
Frame Space The IO95 frame has two backplanes, each divided into five audio/sync zones. Four zones contain six slots and one zone
