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.
