The Revox B215 is a cassette deck manufactured by Studer from 1985 until around 1990. A professional version with different control layout and audio path electronics was manufactured concurrently as the Studer A721. A later improved version was marketed as the Revox B215S. Because it was expensive compared to other consumer models and had exceptionally good mechanical performance and durability, the B215 was used primarily by professional customers—radio stations, recording studios and real-time^[a] cassette duplicators.

The B215 used a proven, reliable four-motor tape transport derived from the earlier B710 model. The B215 differed from the B710 and competing decks of the period in having an unusual, computer-like control panel and elaborate automation performed by three Philips microcontrollers. The deck was equipped with automatic tape calibration, microcontroller-assisted setting of recording levels, and non-volatile memory.

Objective, independently measured and verified specifications of the Revox matched or surpassed those of the best competing decks; comparative tests placed the B215 on the same level as the Nakamichi Dragon and above the flagship models by ASC,^[b] Harman Kardon, Tandberg or TEAC. Reviewers praised the Revox for its exemplary mechanical quality and the expected durability of its tape transport, but criticized it for lower-than-expected dynamic range and shortcomings in usability.
