							General and Features
This unit is a digital video cassette recorder which uses 1/4-inch tapes.
It incorporates digital compression technology so that the deterioration in picture quality and
sound quality resulting from dubbing is significantly minimized compared with existing
analog systems.
Furthermore, since it has a compact 4U size and light weight, the unit can be carried around
or mounted in a 19-inch rack with ease.
The settings for the unit’s setup can be performed while viewing the screen menus on the
TV monitor. With the AJ-D650 unit, both assemble and insert editing are possible through
external control.
Features
Compact size and light weight
This is a 4U size digital VTR. It can be mounted in a 19-inch rack with ease using the
optional rack-mounting adaptors (AJ-MA75P).
Up to 123 minutes of recording
Two sizes of cassette tapes can be used with this unit: M cassette (max. 63 minutes) and L
cassette (max. 123 minutes).The width of the tapes measures 1/4 inch to achieve a
compact design.
Compatibility with consumer products
Consumer cassette tapes shot with digital cameras available on the consumer market can
be played back on this unit using the optional cassette adaptor (AJ-CS750P).

• Slow motion playback is not possible with consumer cassette tapes.
• Consumer cassette tapes recorded in LP mode cannot be played back.
Digital slow motion/jog
The slow motion playback images can be reproduced clearly at any of the speeds given below
using commands from the external controller or other such device: –0.43/–0.3/–0.2/–0.1/
–0.03/0/+0.03/+0.1/+0.2/+0.3/+0.5/+0.75.

• Some noise may occur when the slow motion speed is changed.
• When slow motion playback is used, the image shakes slightly in the vertical direction.
Dialy shuttle operation is possible through the external controller
Shuttle operations enable the tape to be played back with color images at a speed of up to
60 times normal tape speed in either the forward or reverse direction.
Time codes
This unit comes with a built-in time code generator (TCG)/time code reader (TCR). In
addition to the internal time code, an external time code input or input signal VITC can be
recorded in the machine as the LTC time code.
