Panasonic AJ-SD955Bp

Introduction

The AJ-SD930B and AJ-SD955B are multi-purpose

studio digital VTRs which utilize small, 1/4-inch wide

cassette tapes for high quality recording, playback

and editing of video images recorded at a rate of 50

Mbps in addition to recording, playback and editing in

DVCPRO (25 Mbps) format.

These VTRs incorporate digital compression

technology to dramatically reduce deterioration of

picture quality and sound resulting from dubbing,

thereby attaining high picture quality.

These units also come equipped with a variety of

functions, such as assemble and insert functions,

which are necessary when performing editing

operations with a VTR.

(Editing operations cannot be performed with the AJ-

SD930B alone; however, these operations are

possible if an external controller is connected to the

unit.)

These operating instructions include descriptions for both the AJ-SD955B and AJ-SD930B.

Descriptions which concern only the AJ-SD955B are marked with .
