Revox B710 (1981–1982)

A microprocessor-controlled cassette deck from West Germany, with professional tape quality in the compact format.

Overview

The Revox B710 is a stereo cassette deck made by Studer GmbH under the Revox brand in West Germany from 1981 to 1982. It came in silver. The idea was to bring professional tape quality to the compact cassette format. The B710 MkI launched with Dolby B noise reduction, and the later MkII added Dolby C. It has three heads and microcomputer control, and it handles 4-track, 2-channel stereo recording and playback. Revox sold it as high-end audio equipment, with original pricing around $1899 or 2900 German Marks in 1982.

Design

The B710 is a microprocessor-controlled, three-head cassette deck. Record and playback heads are separate, which allows precise tape alignment and high fidelity. Dolby B is on the MkI, and the MkII adds Dolby C for better noise reduction. There are separate mic inputs with input controls, which helps for direct recording.

Maintenance is limited to periodic cleaning of the capstan shafts, pinch rollers, heads, and tape paths. Original MSRP was $1899, or 2,525 Swiss Francs for the MkII.
