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.

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.

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% “pullup” 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.
