Both decks had about the same noise floor, determined by the tape's bias noise (hiss) rather than electronics; the Revox lost due to lower maximum output levels. According to Audio and Stereo Review tests, with Type I and Type IV tapes the B215 reached 3% distortion at only 3–4 dB above the Dolby level, while the Dragon could record and ...
Tape bias is the term for two techniques, AC bias and DC bias, that improve the fidelity of analogue tape recorders. DC bias is the addition of direct current to the audio signal that is being recorded. AC bias is the addition of an inaudible high-frequency signal (generally from 40 to 150 kHz) to the audio signal. Most contemporary tape ...
A 1990 comparative test of 35 Type I tapes showed that their optimal bias levels were within 1 dB of the Type I reference, while Type IV tapes deviated from the Type IV reference by up to 3 dB. [27] Some typical cassette deck frequency response curves showing the effects of different bias settings are provided in the relevant figure.
The tape settings on these decks were EX (normal bias), SX (high bias), and ZX (metal bias). Around 1980, Nakamichi introduced the third generation of 1000 and 700 three-head decks. The 1000ZXL and 700ZXL had full metal capability as well as normal and high bias abilities and had built-in computers for calibrating the decks to a specific tape ...

The Nakamichi Dragon is an audio cassette deck that was introduced by Nakamichi in 1982 and marketed until 1994. The Dragon was the first Nakamichi model with bidirectional [a] replay capability and the world's first production tape recorder with an automatic azimuth correction system; this feature, which was invented by Philips engineers and improved by Niro Nakamichi, continuously adjusts ...
