  • Page 56: Notes About Backup/Restore

    Of course, there is nothing wrong with this practice but it may get awkward trying to keep track of your backups and so, in view of this, to avoid this situation, you might prefer to use new, freshly formatted tapes when attempting a backup. Page 46 DD8 plus Version 2.20 - September 1998...

    When the Qlist is loaded, the DD8’s project deals with overlapping cuts and track output assign- ments using two schemes. If cuts use different outputs (for example, a mixture of outputs A, B or AB, the following track assignments will be used: Page 58 DD8 plus Version 2.20 - September 1998...

  • Page 69: Saving Projects To Dd1000 Disks

    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. DD8 plus Version 2.20 - September 1998 Page 59...

  • Page 70: Multiple Disk Drive Systems

    Furthermore, if a DD1000 Qlist has audio that exists on one disk only (as is invariably the case), the DD8 assumes that the audio is on the same disk as the Qlist and so it will also playback properly. Page 60 DD8 plus Version 2.20 - September 1998...
