Safety and Precautions
1) Read Instructions - Read all the safety and operation instructions before operating the
DF64 Digital Frame.
2) Heed Warnings – Follow all warnings on the DF64 and in these operating instructions.
3) Water and Moisture – Do not use the DF64 near water.
4) Heat – Locate the DF64 away from heat sources.
5) Power Sources – Connect the Am713/MA703 only to a power supply of the type
described in these operation instructions or as marked on the DF64.
6) Power Cord Protection – Route power cords so that they are not likely to be walked
upon or pinched by items placed on them.
7) Object and Liquid Entry – Do not drop objects or spill liquids on the DF64.
8) Damage Requiring Service – The DF64 should be serviced only by qualified personnel
when:
a) Objects have fallen, or liquid has spilled into the DF64; or
b) The DF64 does not appear to operate or exhibits a marked change in
performance; or,
c) The DF64 have been dropped or there is damage to a chassis.
9) Servicing – Do not attempt to service the DF64 beyond those means described in this
operation manual. All other servicing should be referred to the Euphonix Tech Support
department.

DF64 Digital Frame Manual Version 1.0 ©1999 Euphonix, Inc. Page 5
10) Fuse replacement – To prevent electric shock and avoid risk of fire, replace fuse only
with the same type and rating.
11) To prevent electric shock, do not use the DF64 polarized plug with and extension cord,
receptacle or other outlet unless the blades can be fully inserted to prevent blade
exposure.
12) Grounding or Polarization – Do not defeat the grounding or polarization of the DF64.
13) Cooling - Ventilation for cooling is provided to the DF64 via four rear panel mounted
fans. These fans draw cooling air through the chassis from the openings on the front
panel. To avoid damage to the unit, do not block the fans or the front panel openings.
Do not disconnect the fans.
THERE ARE NO USER SERVICEABLE PARTS IN THE DF64. However, individual cards
can be swapped by the user.
Power On Sequence
It is recommended that the DF64 Digital Frame(s) are powered on after all the other System
5 components have been powered on and the Virtual Mixer has been loaded in all the
corresponding Digital Pilot computers.
CE/TUV/UL/CSA
The DF64 is fully CE compliant. Documentation is available from the factory.

Component Overview
Functional Description
The DF64 Digital Frame is the Digital Signal Processing Center of System 5. Digital Audio is
routed to and from the DF64 in MADI. Control of the DF64 is provided by a Digital Pilot
Computer (one per DF64,) which in turn communicates with the System 5 Control Surface. Thus
the DF64 is under control of the System 5 system operator.
The DF64 assembly is a standard 19” rack width and 9RU high.
Applications
In its role of Digital Signal Processing Center for System 5 , the DF64 performs three
functions;
•Signal I/O
•Signal Routing and Synchronization
•Signal Processing
There are 3 different types of cards in the DF64 that address each of the above functions.
The number and type of cards in the DF64 are configurable. There are one to four DF64
frames per System 5 , each of which can contain up to 14 cards. One SC253d Digital Pilot is
required for each DF64.
Signal I/O– MM641 MADI Interface Card
All audio I/O is handled by the MM641 MADI Interface Card. MADI signals input at 24 bit
fixed point resolution are converted to 32 bit floating point resolution for distribution over the
backplane to other cards (the SP-661 Signal Processor Cards use 40 bit floating point
processing internally—see below). Each MM641 card can input 224channels and output 224
channels of audio (56 channels per MADI port.) The MADI cards can also support 64 channel
MADI if an application requires this. When operating at 96kHz sample rates, each MADI port
handles 28 audio channels.
Signal Routing and Synchronization – FC631 Frame Controller Card
All patching between I/O, Channels, and Busses is done on the Time Division
Multiplexed(TDM_ bus and controlled by the FC631 Frame Controller Card. The FC631 Card
also provides a FireWire interface to the SC253d Pilot Computer. The DF64 includes a slot for a
backup FC631 card, for applications where maximum fault tolerance is required.
The DF64 typically acts as a Sample Rate Slave in System 5 synchronization, although it can
be a Master if desired. The Sync Source section on the FC631 front panel allows the user to
select between AES or Word Sync (slave mode) or Internal Sync (master mode). Once locked to
the selected sync source, the FC631 distributes a sync clock to the other cards in the DF64
frame and outputs a reference clock on its AES and Word sync output connectors. The master
Sample Rate clock signal for the DF64 and all System 5 system components comes from the
Studio Hub (SH612), which in turn can be used to synchronize other digital components in the
studio.

Signal Processing – SP661 Signal Processor Card
The SP661 Signal Processor card performs all signal processing functions in the DF64. This
card comprises six Analog Devices SHARC processors, massive DMA facilities for transferring
audio data, and a RISC CPU for management of card functions. The programmable DSP
architecture on the SP661 card allows it to perform channel processing, mixing, or various other
signal processing tasks.

Front Panel, FC631 Frame Controller
AES Sync In (3-pin Lemo Female) AES/EBU formatted sync input. The
DF64 clocks to the signal at this port when Sync Source is set to
AES. An XLR female to LEMO adapter cable is provided.
AES Sync Out (3-pin Lemo Male) AES/EBU formatted sync output. This
signal is active regardless of the selected sync source. A LEMO
to XLR male adapter cable is provided.
Word In (BNC) TTL-level square wave Sync Input. DF64 Sample
rate is clocked to the signal at this port when Sync Source is set
to Word.
Word Out (BNC) TTL-level square wave sync output. This signal is
active regardless of selected sync source.
IEEE 1394 ports (2) (IEEE 1394) High speed communication interface to the
SC253d Pilot Computer. This interface carries real-time control
and metering data between the SC253d and the DF64. The
cable from the SC253d can be plugged into either of the two
ports.
Chassis ID Display Each DF64 chassis must be assigned a unique ID which
identifies it among multiple frames in a system. The ID is set
using a rotary switch located on the Backplane PCB. The
System is shipped with the ID switch preset to the proper
number, so users will not normally need to access the switch.
The switch position must match that of the corresponding Digital
Pilot computer.
Sync Source LEDs The top three LEDs in the Sync Source section indicate
the selected sync source: AES, Word, or Internal. The sync
source is changed by pressing the select button (a paper clip or
similar tool is required) Refer to the System 5 Operation Manual
for information on changing the sync source.
Sample Rate LEDs The bottom six LEDs in the Sync Source section indicate
the sample rate that is measured by the FC-631 card. Standard
sample rates include 44.1kHz, 48kHz, 96kHz, and the 0.1% “pull-
up” and “pull-down” rates associated with each of these standard
rates. If the FC631 is locked to a non-standard sample rate, the
CUSTOM LED will be lit.
Select Button Use this button to manually select the Sync source (and
Sample Rate, if Internal Sync is selected) Refer to the System 5
Operation Manual for information on changing the sync source.
Locked LED Indicates that the FC631card is receiving and locked to
the selected sync source. This LED must be lit to ensure
proper audio operation of the DF64. .
Active LED When lit, Indicates that the FC631 is actively controlling
the TDM bus. In a system with two FC631 cards, this LED is
