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 units setup can be performed interactively while viewing the screen menus on the TV monitor, and editing functions include both assemble and insert editing.

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-MA34HP).

Up to 123 minutes of recording

Two sizes of cassette tapes can be used with this unit: the news-gathering cassette (max. 63 minutes) and general purpose 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).

<Note>

Slow playback of consumer cassette tapes will not produce the smooth operation produced by slow playback of DVCPRO cassette tapes.

Digital slow motion/jog

Digital slow-motion technology created originally by Panasonic enables noiseless images to be played back from speeds ranging from still picture to approx. ±1/2 × normal tape speed.

<Note>

Some noise may occur when the slow motion speed is changed.

Time codes

This unit comes with a built-in time code generator (TCG)/time code reader (TCR). In addition to the internal time code, time code facilities include external time code input as well as recording of the input signal VITC code.

Multi-function input/output interfaces

Analog input/output

Component (Y, PB, PR) and composite signal input and output connectors are provided.

Serial digital input/output

Digital component interfacing complying with the SMPTE 259M-C/272M serial digital signal standard is possible when the optional component serial interface board (AJ-YA750P) is used.

AES/EBU audio input/output

Digital audio input and output connectors are provided.

9-pin (RS-422A)/(RS232C) remote

In addition to the standard 9-pin serial (RS-422A) connector, RS-232C and 25-pin parallel connectors are also featured.

The RS-422A connector enables another VTR to be operated in parallel with the unit if a looping connection is used for the two units.

2-channel high-sound-quality digital audio

Sound can be edited separately for two channels while channel mixing capabilities are also available. One channel is provided for the analog cue track.

Dial jog/shuttle

All playback is free of noise bars with jog operations performed when the variable range is set to between –0.43 and 1 × normal tape speed. Shuttle operations can be performed up to 60X normal tape speed in both forward and reverse directions. Color images are welldefined even during high-speed searches.

Automatic editing functions

Besides assembly and insert editing, can also be performed.

Menu-driven setup

The setup settings, which are conducted prior to operating the unit, are performed while viewing the screen menus either on the unit’s display or a TV monitor.
