The output power at 0 dB is 45 mW, so that even low-efficiency headphones can be monitored with sufficient volume. This allows accurate reference signals to be recorded and played back to align the levels, thereby preventing the effects of differences in tape sensitivity.Įquipped with 10kHz-8dB test signal, bias adjustment knob can be used to obtain the optimum bias value according to the type of tape. You can record your absence by combining with a timer.Įquipped with a 400Hz/0dB test signal function. This reduces the possibility that the sound quality deteriorates due to the induction between cords when cords are used frequently. It is equipped with a phase correction circuit, and the phase rotation is suppressed within 30 degrees in all frequency bands.īy using a printed circuit board for the internal layout and thorough use of connectors, the number of cords used is reduced to more than ten. It is also superior in durability and can be used for more than 10,000 hours. We have been conducting research based on our long experience in head manufacturing, and have achieved recording and playback at 20 kHz with a 0.9 micron gap by three dimensional improvements in material processing technology.Ĭompared with other magnetic materials, the Superhead is superior to other magnetic materials by more than 5 dB in the third harmonic distortion, superior it is also superior to other magnetic materials in the even and odd order distortion beyond the third order. Therefore, recording and playback at 20 kHz was considered impossible with conventional dual-use recording heads. In order to perform playback up to 20 kHz, a gap of 1.2 microns or less was required. Generally, the ideal gap width for recording heads is 4 to 6 microns. In addition, the Superhead realizes narrow-gap recording. It also has excellent linearity and excellent frequency and strain characteristics. The curves for the magnetization and demagnetization processes are very close. The material used for this head is crystalloid, which has extremely high μ at both low levels and high frequencies. The head is equipped with Nakamichi's own super head. This cassette deck is an improved version of the 600 with a newly developed superhead.
