Introduction
The model AJ-SD755 multi-purpose studio-use digital
VTR employs 1/4-inch wide compact cassette tapes to
record, play back and edit material in the DVCPRO
(25 Mbps) format.
It is also capable of recording and playback in DV
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.
Before operating this unit, check that all of its
accessories are present and accounted for.
