A guide to the Revox B77 reel-to-reel recorder, its professional uses, playback requirements and role in preserving analogue recordings.
What is the Revox B77?
The Revox B77 is a professional reel-to-reel tape recorder from the Revox range. It was designed for reliable recording and playback and is particularly associated with serious home recording, studio, institutional and archival applications.
What kind of tapes can it play?
The exact tape configuration matters. Reel-to-reel recordings can vary by tape width, speed, track format and equalisation. Before playback, the tape should be identified rather than assuming that every quarter-inch reel uses the same configuration.
Why is a B77 useful in preservation work?
Preservation depends on reproducing the original recording as accurately as practical. A suitable, well-maintained professional deck provides controlled transport and stable playback, while the technician can select the correct speed and track configuration for the source.
How are reel-to-reel recordings prepared for digitisation?
The process normally starts with inspection for contamination, physical damage, poor winding, mould or signs of binder deterioration. The tape is then matched to appropriate playback equipment, transferred in real time and checked for faults or drop-outs.
What digital files can be created?
For preservation projects, high-resolution WAV or BWF files are commonly used for audio masters. Access copies can also be created in formats such as MP3 where convenient listening or distribution is required.
The important point
A historic reel should not simply be put onto the nearest working tape deck. The recording format, tape condition and original recording characteristics should be considered first.
