FRONT PANEL - INSERTING AN MO DISK
Assuming you have an MO drive installed, the disk is inserted thus:
WRITE PROTECT SWITCH
(This side)WRITE PROTECT SWITCH
The side you wish to use is inserted face up. Power must be on for the disk to be accepted as the
load mechanism is motorised.
Disk Activity Led Eject switch
When the disk is in use (i.e. playing back, recording, saving, loading, etc.), the DISK ACTIVITY
LED will flash.
To eject the disk, press the DISK EJECT button. Power must be on for the disk to be ejected as
the mechanism is motorised.
NOTE: If there is some problem ejecting the disk and/or power is not applied to the drive, you
can eject the disk by inserting a small metal tool in the small hole alongside the disk eject
button. Something like a rolled out paper clip will do it but a special tool is recommended. This
tool may accompany the drive unit.
It is possible to write protect MO disks to prevent accidental erasure, editing, formatting, etc.. To
do this, slide the WRITE PROTECT switch to the PROTECT position. If you only intend to
playback from the disk, it is a wise precaution to write protect the disk to prevent accidental
damage to a project.

This connector can be used to replace the Ôpre-readÕ output generated by some dubbers that
have a second playback head mounted before the main playback head. Note that the DD8 does
not generate an audio signal here. Instead, it uses an oscillator which is switched on and off as
the playback signal reaches a preset threshold.

In this case, PROJECT 1 is selected for backup. The left hand side of the LCD will show how
many files are selected. In this case, just one.
You may also select several files for backup in this way. As in other disk pages, arrows appear to
indicate files that are Ôoff-screenÕ. Use the DATA +/- keys to scroll through the list.
Files selected by mistake can be de-selected by pressing the SELECT key (F4/F5) a second
Once you have selected the file(s) you want to backup, press EXIT (F6) to return to the main
SCSI BACKUP page and proceed with the backup.
BACKING UP ALL PROJECTS AND/OR LIBRARIES
If you have selected ALL PROJECTS, ALL LIBRARIES or ALL PROJS & LIBS, all you need to do
is press the ENTER key. All the projects and/or libraries on the disk selected in the DISK ID field
will be backed up. If any projects and/or libraries use audio from any other connected disks,
these too will be backed up to the destination SCSI tape.
The exact amount of time the backup will take depends on the amount of material being backed
up. Backup speed is approximately five times real-time (i.e. ten minutes of audio will take ap-
proximately 2 minutes to backup).
BACKING UP AN ENTIRE DISK
As well as selectively backing up chosen files or backing up all projects and/or libraries, you may
also make a duplication of the disk by selecting ENTIRE DISK in the BACKUP TYPE field.
NOTE: Although ENTIRE DISK may seem the same as ALL PROJS & LIBS, there is a differ-
ence. ALL PROJS & LIBS will backup everything from the selected disk but it will also backup
any audio from other disks that are used in the projects and/or libraries being backed up. EN-
TIRE DISK, on the other hand,
only backs up the audio on the selected disk, not any audio
referenced on other disks. ALL PROJS & LIBS, therefore, is more suitable for backing up your
work whilst ENTIRE DISK is a better selection to make if you just want to make a safety copy of
PERFORMING THE BACKUP
Regardless of the backup type you have selected, to actually perform the backup, simply press
the ENTER key. You will then see this screen:
Here, the DD8 is getting the tape ready for the backup. First of all, it will look at the tapeÕs
directory to make sure that there is no backup of the same name. If a backup of the same name
exists on the tape, you will receive this message:
In this case, press ABORT and give the backup a new name and try again (i.e. press ENTER) or
insert a new tape and press CONTINUE.
NOTE: You will need to specifically go to your tape drive and use the front panel EJECT key
to eject the current tape and insert a new one.

OUT A CUTS
OUT AB CUTS
OUT B CUTStrack 1 +2 (track 1 if mono)
track 1 + 2 (track 1 if mono)
track 3 + 4 (track 3 if mono) DD8
If all the cuts use the same outputs (for example, all cuts are assigned to output A), the following
track assignments will be used on the DD8Õs project. For example:
Stereo cut 1
Stereo cut 2 Stereo cut 3
New cut is played back overlapped
The cuts are assigned to tracks 1+2/3+4 in a similar way to the manner in which the DD1000
assigns cuts to voices. In other words, where cuts in a DD1000 Qlist overlap, whereas on the
DD1000 they will play correctly (owing to the DD1000Õs ÔvoiceÕ assignment), on the DD8, they
will be placed on adjacent tracks so as to play correctly.
SAVING PROJECTS TO DD1000 DISKS
When a DD8 project is saved to a DD1000 disk, a DD1000 Qlist of the same name is automati-
cally created and saved to the disk in addition to the DD8 project itself. This allows you to play
simple projects created on a DD8 on a DD1000. The DD8 makes its best attempt to store cues
for playback on the DD1000. It starts at track 1 and then continues until all the tracks are stored
or all 256 DD1000 cues have been used up. After saving a project to a DD1000 disk from the
DD8, the next time this disk is used you can choose to load the DD8 project rather than the
DD1000 Qlist by pressing the SELECT key (F5/F6) on the DISK SETUP page.
WARNING: If you load a DD1000 Qlist into a DD8, work on it and then save it again on the
DD8 you will lose any FADE and MIDI events that may have been on the original and you will
lose all cut names.
PLAYING DD1000 DISKS CREATED ON A DD8 ON A DD1000
Some degree of backwards compatibility is also possible between the DD8 and DD1000 and
any DD1000 disks you have worked with on the DD8 may still be used on a DD1000.
Recordings can be made on the DD8 to a DD1000 disk in the usual manner (i.e. select a track
for record, press PLAY+RECORD) but the DD8 uses the following rules to decide whether a
recording is mono or stereo when recorded on a DD1000 format disk.
¥ Adjacent channel pairs of tracks enabled for record are recorded as DD1000 stereo takes.
¥ Non-adjacent and remaining channels are recorded as DD1000 mono takes.
REC ENABLE track = 2
REC ENABLE tracks = 2+3
REC ENABLE tracks = 2+4
REC ENABLE tracks = 2+3+4+52 = MONO
2 + 3 =STEREO
2 = MONO, 4 = MONO
2 + 3 = STEREO
, 4 + 5 = STEREO
NOTE 1: When recording in stereo, the first track of the pair is always assigned to the left
channel of the DD1000. For example, in example number 2 above, track 2 would be assigned
to the left channel and track 3 to the right.

NOTE: YOU MUST SELECT ONE OF THE SMPTE/EBU+RS422 OPTIONS AT A FRAME
RATE APPLICABLE TO YOUR AREA WHEN USING RS422 MASTER.
These options are available at all frame rates. SMPTE/EBU from the VTR is still connected as
usual to the LTC option boardÕs input and the SYNC key must be switched on. The DD8 will
receive timecode information in playback from the LTC connection but, when working in slow
motion, it receives timecode over RS422 making locking of the two machines tighter.
Switching on the SYNC key engages the RS422 function. Because of the frame accuracy limit
imposed on the DD8 by the VTR over RS422, it is sometimes necessary to ÔisolateÕ the DD8 for
greater editing accuracy. To do this, simply switch off the SYNC key - this will allow the DD8 to be
used Ôstand aloneÕ.
As a practical example, letÕs say you are trying to sync a door slam sound effect in the DDÕs
project with the picture on video. You could, of course, do everything referenced to frame accu-
rate picture but, you just cannot get the door slam precisely in sync. By switching off the SYNC
key, you can momentarily disengage the VTR, ÔisolatingÕ the DD8 and you can place the sound
effect, nudging it backwards or forwards in sub-frame increments on the DD8 until you think itÕs
at the right position. You can then re-engage the VTR by switching on the SYNC key again and
trying it out against picture. You can repeat this process until itÕs perfectly in sync.
LAYBACK FUNCTION IN RS422 MASTER
LAYBACK is a process where you have material on the DD8 that you wish to ÔmasterÕ onto a
VTR or other such RS422 equipped machine (such as an RS422 DAT machine). For example,
you may receive a video tape with just dialogue on it. This is sync-transferred to the DD8 where
it may be edited and tidied up if necessary and sound effects, music and other ÔsweetenersÕ can
be added using the DD8Õs multi-track capabilities. Finally, the whole thing is transferred back to
To use the LAYBACK function, press LAYBACK (F4/F5). You will see this screen:
The parameters are:
LAYBACK TO TRACKS Here you may select which of the VTRÕs tracks the material will be
recorded to. You may select VTR tracks 1, 2, 3, 4, 5, 6, 7, 8 (mono)
or 1+2, 3+4, 5+6, 7+8 (stereo) or 1-4, 5-8 or 1-8.
TRACKS ENABLED Here you may select whether the layback (i.e. the mixdown) will be
to the VTRÕs analogue tracks or its digital tracks. You may also
select ANALOG+DIGITAL which will cause the layback to be re-
corded to both the analogue and the digital audio tracks of the
