Introduction; Thank You; Dd1500 System Overview - Akai DD1500 User Manual

The staff at Akai would like to thank you for buying the DD1500. Developed by the same
team of engineers that developed the Akai DD1000, the world's first Magneto Optical Disk
recorder/editor, we are confident that the DD1500 will be a sound investment, offering
many years of reliable service and will be a product you can rely on in your daily work.
The DD1500 is a powerful multi-track digital audio recorder and editor. Being a dedicated
system with no host computer required, its performance is optimised for recording, editing
and syncing audio to picture and so offers ease of use and speed of operation with no
prior knowledge of computers and/or hard disk digital recording required.
The system comprises three main units:
DD1500m
DD1500x
DD1500a
DL1500
Version 2.00 - March, 1996
This is the system's main signal processor and contains
developed especially for the DD1500m. All the timecode interfaces you are
likely to require such as SMPTE, BI-PHASE, VITC, RS422, etc., are
provided as standard as well as a variety of wordclock inputs and outputs
allowing the DD1500 to be integrated into virtually any professional work
environment. Two digital AES/EBU inputs and outputs are supplied as
standard and optional digital i/o boards may also be installed in the
DD1500m.
This is the system's disk drive. This can house up to two Sony 1.3GByte
Magneto Optical (MO) disk drives or an MO and a fixed hard disk. It
connects to the DD1500m using SCSI.
This unit allows you to add analogue inputs and outputs to the system as
you require. Each unit may contain up to eight inputs and eight outputs
and two units may be used with the system.
This is the system's controller. It offers dedicated keys for most day-to-day
functions making the system fast to learn and easy to use. Dedicated track
select and transport keys and autolocator functions give it the feel of a
normal MTR whilst sophisticated editing functions allow you to edit audio
quickly and precisely. The specially designed jog wheel allows you to
'scrub' audio across all 16 tracks just like reel rocking ordinary tape and,
using RS422 control of a VTR, you can jog audio and picture together.
The DL1500 also has a special custom LSI developed purely for
generating the graphics you see on the external VGA monitor. Being
optimised for the task, you will see that screen updating is exceptionally
fast, offering smooth waveform scrolling and lightning fast zoom in and
zoom out. At no time are you left sitting there waiting for the screen to
update and waveforms to re-draw. A simple but effective colour scheme
eliminates eye strain even in prolonged sessions. You will no doubt be
pleased to know that the screen you see on the monitor is the only one
you work in and there are no multiple, stacked 'windows' to confuse you
and no separate record or edit modes to have to enter making operation
fast and consistent.
