AUDIO DECK

Component Overv i ew

The Audio Deck is a processing sub-system that moves digital audio data between SCSI storage devices and MADI (Multi-channel Audio Digital Interface) signal ports. In essence, this R-1 module converts data transmitted and received in bursts (packets) from storage devices into evenly clocked synchroniz ed streams of digital audio.

The Audio Deck uses a control processor to know when and what to record or play. This control system c o mmunicates with the Pilot Computer for information about stored settings, audio event schedules, and user input. The communication path for such control data is IEEE 1394. This control p ath is also designed to allow the Audio Deck to move actual audio data to and from the Pilot Computer, where the R-1 system can be attached to a network (including machines of various operating systems) or to other storage devices formatted for the Windows operating system. R-1 release 1.0 software, however, does not include audio data transmission features.

The Audio Deck includes a complete Transport Engine. Not only does the deck convert SCSI to and from MADI, but the deck provides the mechan isms for this process to be controll ed in very much the same way as a conventional tape machine even while doing th ings that a conventional tape machine cannot begin to do, such as Locate instantly to any Cue. Some features of the Transport Engine.

• 4 SHARC DSPs

• Same-track real-time punch and edit crossfades

• 24 tracks of playback or recording from a single drive

• 24 tracks of playback and simultaneous seamlessly monitored punch in/out from

two drives

• 24 tracks of constant Sample Rate varispeed recording and playback

• 24 tracks of Jogging/Scrubbing transport motion

• Clickless start and stop of audio playback

The Audio Deck also includes a router and monitoring mixer. The deck provides basic routing of it’s input MADI channels to its available 24 channels of recording. This is in addition to any routing of MADI external to the deck. The deck also provides a monitor mix of its 24 channels of output.

IEEE1394

IEEE 1394 ports (3) (IEEE 1394) The 1394 high speed communication protocol allows that any port

from any module can be connected to any port on any other module and that the cables can “star” from one device, or can be daisy chained from device to device. The recommended 1394 cable c onfiguration for the R-1 Audio Deck is to co nnect a cable from any of the three p o rts on the Audio Deck to any of the three po rts on the Pilot computer.

Word In (BNC) May be connected to a Word Clock source if Word Clock is the master

Sample Rate clock for the R-1 system. In the standard R-1 configur ation where the Studio Hub is a short distance from the deck, AES is recommended for synchronizing the Audio Deck. In configurations where the Studio Hub is located remotely, the Word Clock output from the Studio Hub may be used as the master Sample Rate clock, and is then provided to this Audio Deck input.

Word Out (BNC) May be connected to the Word Clock input of a second chained Audio

Deck in a multi-deck R-1 system. When an external Word clock input is present this connector provides a regenerated version of the input signal. When no external Sample Rate source is detected this connector outputs the internally generated clock signal. This later configuration, where the Audio Deck is the clock master, is not a recommended mode.

AES In (XLR Female) Connected to one of the Studio Hub’s AES Sync Outputs in the

standard configuration. This is the recommended clock for t he Audio Deck where the Studio Hub is a short distance away.

MADI In (BNC) In the standard configuration this is connected to the Studio Hub MADI

output #1.

MADI Out 1 (BNC) Connected to the Studio Hub MADI #2 input in the standard

configuration. From 1 to 24 channels represents Aud io Decks main channels of disk playback and input monitoring. Channels 25 and 26, as well as 27 and 28 each contain stereo monitor mixes, but the 25/26 pair are reduced in signal strength by – 12 dB.

MADI Out 2 (BNC) Same as MADI Out 1. Provided as a built-in Mult. Can be used with

MADI metering.

External SCSI (68 pin Wide SCSI Dsub) External conn ector to internal Audio Deck SCSI chain.

Exabyte back up tape drive connects here. Do not connect additional SCSI drives here. Active SCSI terminator must be connected at this port if Exabyte is not connected.

Synchronization

Sample Rate

The Sample Rate of th e Audio Deck is set by one of three extern al source signals or internally by means of crystals and associated circuitry. The Sample Rate source is determined automatically by the presence of signals at the time the Audio Deck is powered on or by settings in the R-1 software application. The order in which each external signal is tested for its presence is as follows:

AES Word MADI

As soon as a signal is d etected it becomes the source for Sample Rate clocking of the Audio Deck. In the event that none of these signals are present the Audio Deck will provide an internal clock dr iven by crystals. The default internal Sample Rate of the Audio Deck is 48 kHz. This default internal rate can be overridden by the R-1 software to generate 44.1, 48kHz. As the standard R-1 configuration also includes a Studio Hub, this software control over internally generated Sample Rate is not directly user accessible in version 1.0.

Current Time Position

In the standard configuration, the current time of the R-1 sy stem is established by the Studio Hub, either according to the Studio Hub’s internal time code generator or according to external time codes provided to the Studio Hub. The R-1 application software sets the Studio Hub as the system time code master by default. In this configuration the Studio Hub inserts time code information on track 55 and 56 of the MADI stream to the Audio Deck. To make use of this time code th e Audio Deck must have a 1394 connection to the Studio Hub (both Audio Deck and Studio Hub are attached to the Pilot Computer in the standard configuration).

MADI

The MADI input channels 1-54 can be mapped under software control to the available 1-24 channels of recording (and input monitoring) of the Audio Deck. See the R-1 Operation Manual section on Input R outing. MADI input channels 55 and 56 are used within the R-1 system (when a Audio Deck and Studio Hub are both present) to convey time code position data.

The MADI output channels 1-28 are hard-mapped as fol lows.

1-24 Playback / input monitoring channels

25-26 Monitor mix (for ancillary analog outputs). All odd numbered channels

of the 24 channels of playback and input monitoring are summed left and all even numbered channels of the 24 channels of playback and input monitoring are summed right and the results of both left and right are attenuated by –12 dB. The left channel mix is output via MADI channel 25 and the right channel mix is output via MADI channel 26.

27-28 Monitor mix (for auxiliary digital outputs / digital copy tracks). All odd numbered channels of the 24 channels of playback and input monitoring are summed left and all even numbered channels of the 24 channels of playback and input monitoring are summed right. These mixes are not scaled or attenuated in any way. The left channel mix is output via MADI channel 27 and the right channel mix is output via MADI channel 28. As the mixes are not scaled they will clip if full strength signals are present on all channels. However when two adjacent channels are soloed the resulting unmodifi ed output goes directly to channels 27 and 28. This feature allows for digital copies to DAT or other stereo digital devices using the ancillary digital outputs of Euphonix converters such as the MA-703.

SCSI

The Audio Deck uses SCSI 3 Ultra W ide storage technology. However, the addressing scheme is SCSI 2 as the Audio Deck is designed and optimized for seven devices in addition to the Audio Deck controller. Each Audio Deck is built to include two Kingston drive trays (receptacles for the Kingston drive carrier). Only two real-time (random access) drives can be installed – one each for the corresponding Kingston trays. These devices are always addressed as SCSI #1 and SCSI #2, and show up as such in the softw are directories.

Approved Real-tim e Drives and Hardware

Only one drive is appro ved for use with the R-1. Manufacturer: IBM Series: Ultrastar 9LZX Model Number: DRVS-09V IBM part number: 08L8260 Installation manual:

Back up & Drive Expansion

The Audio Deck includes a rear panel SCSI connector for adding an Exabyte Mammoth drive to the SCSI chain. The Mammoth can be purchased from Euphonix or elsewhere as an externally enclosed desktop unit, or from Euphonix as a rack mount unit. The following SCSI configurations are typical.

Audio Deck One or two 9 gig SCSI hard drives only. Uses SCSI ID# 1 and SCSI ID# 2 of a single SCSI chain. IDs do not travel with the drives. The Audio Deck (and its Kingston mount) determine the ID# for whatever drive is plugged in.

DX-202 E Rack mounted expansion bay for adding either one or two Exabyte Mammoth tape drives (SCSI ID# 0) to each of either one or two Audio Decks. Each Exabyte installed in the 202e is on a separate SCSI chain. Only the Exabyte Mammoth can be connected in addition to the Audio Deck’s own real-time audio drives (at SCSI ID# 1 and SCSI ID# 2) on the Audio Deck’s SCSI chain.

Back up Expansion bays are interconnected via the external hi-density SCSI connector on the back of each unit. In version 1.0 only a single Exabyte mammoth tape drive can be con nec ted to the external SCSI 3 connector.

SPECIAL OPERATING PRECAUTIONS

Do Not Remove Drives without Clo sing Medi a

To preserve data integrity in your R-1 system, DO NOT REMOVE AUDIO DRIVES while the R-1 has a Tit le loaded, and particularly not when the transport is in Play. Removing drives while stopped, but w ithout first closing the Title will cause the R-1 to try to access drives that are not there. If you have completely swapped out the drives, there is the potential that the data intended for one drive could be written to the wrong drive resulting in data corruption. The R-1 DOES have mechanisms to try to recognize unexpected drive remova ls, and the R-1 will attempt to gracefully notify you that the media has accidentally been dis-mounted or replaced. However, it is not recommended t hat the media be removed in such a fash ion. Doing so may jeopardize data integrity.

The Audio Deck loads its drive information when the R-1 application is booted or when the Media Open c o mmand is used on the Remote or when D isk or Tape Media is selected in the Audio Browser of the Directory Panel then the Load command is issued. Media Close and Media Unload should be used when media is be dismounted and not reloaded. Fo r instructions on these operations see the R-1 Operation Manual in the sect ion called File Management.

Please note that starting the R-1 application will always load all media and reset the decks. Reseting a deck will also load the SCSI media, so switching to 96kHz operation (which changes the code running on the deck) will also reload all media.

There Must Always Be A Drive in Audio Deck #1 at SCSI ID #1

Title information is always saved to drive one (SCSI ID #1) on the first Audio Deck when any Title is saved. There must be a drive installed at SCSI ID #1 for Title saving to work properly. This target drive ma y be changed if a problem occurs or if a Title was created on a higher numbered drive on a different system. This change of the Title drive is NOT recommended for anything but very spec ific operations and should be changed back immediately. See the R-1 Operation Manual for details on this parameter.

External SCSI Port Is Restricted

The R-1 Audio Deck supports the attachment of an Exabyte Mammoth drive on the external SCSI connector in the upper right of the rear panel. This is the only approved device for attachment to this connector. DO NOT ATTACH ADDITIONAL HARD DRIVES TO THE EXTERNAL SCSI CONN EC TOR.

Both Drive Bays Should Be Full

The Audio Deck should not be powered on with a drive bay empty. Each Kingston tray should be populated with a drive or a Kingston cover-plug to ensure that the air circulation within the Audio Deck is according to design.

Do Not Change Drive Addresses

The small screwdriver packaged with the software and documentation is for the Kingston drive receiver frame on your R-1 Audio Deck. With this screwdriver it is possible to change th e SCSI addresses for the drives load ed into that frame. However, the changing of SCSI addresses is NOT RECOMMENDED.

Setup (Standard R-1 Configuration)

The Audio Deck is recommended for the third position in the rack after the Studio Hub (top of rack) and Pilot Computer (seco nd in rack - below Studio Hub).

• Attach the provided IEC compatible power cable to the IEC inlet. Attach other end to wall outlet with appropriate plug adapter if necessary. The Audio Deck power supply will automatically set itself to work with the voltage in your country (110, 220, or 240). DO NOT POWER up unit at this time.

• Attach the provided Red BNC Coax cable from the Studio Hub MADI #1 Output to the Audio Deck MADI Input.

• Attach the provided Red BNC Coax cable from the Audio Deck MADI Output 1 to the Studio Hub MADI #2 Input.

• Attach the provided yellow XLR cable from the Audio Deck AES Sync In connector to one of the Studio Hub’s AES Sync Out connectors.

• Attach the provided green 1394 cables from any of the three 1394 connectors on the Audio Deck to any of the three 1394 connectors on the Pilot Computer.

Power Up Sequence

The R-1 modules can be powered up in almost any sequence. We suggest that you monitor the LEDs on the front panels at power up to insure that the intended settings are in effect.

We recommend that the Audio Deck is booted up third in the R-1 system after the Studio Hub and the Pilot computer.

Wait about 10 seconds for the Audio Deck to boot fully. The dr ive ID indicator lights will stop flashing when the Audio Deck is ready. The AES LED should light steadily, indicating that the Audio Deck is receiving the Sample Rate Source from the Studio Hub.
