Technics RS-M95 - Professional Series (1979)

cassette deck

The RS-M95 was the last incarnation of the very successful series introduced with the RS-M85. Technics has designed the RS-M95 with three heads, each designed for its special role in the recording and playback process. For low distortion. the recordinq head gap is set at a precise 5 micron. The playback head's tiny 1 micron gap provides a new level of high range frequency response. Both heads feature a special version of Technics' own HPF material for the gap and core to raise the saturation flux density to the heights needed for high input metal tape recording. To bring out its full potential, metal tape needs about twice the recording bias current of normal tape, plus specialized (recording) equalization to deal with its high frequency characteristics. Therefore, the M95 not only has the conventional three positions on its tape selector, it also features a metal position especially for the new breed of metal particle tapes. On top of this, you get added flexibility by using independent fine bias adjustment knobs for each tape type. These can be set for  +/-20% of the conventional bias current to deal with each and every brand of tape. And the built-in oscillator provides 400Hz/8kHz test-tone signals for use in this calibration. 

Wow and flutter were the lowest ever in a Technics cassette deck thanks to the combination of the proven quartz phase-locked direct-drive capstan motor and a computer controlled tape tension control system in the reel drive section. As the major determinant of tape travel accuracy, the capstan motor features highly stable, constant rotation. The servo system is based on a quartz oscillator reference frequency and is phase-locked with Technics' famous planar-opposed DC brushless, coreless, slotless, direcl-drive motor. To bring out the full potential of the quartz DD drive system and ensure optimum head contact with the 3-head configuration, Technics has provided the M95 with a remarkable tape tension control circuit. Based on detection of take-up reel rotations and calculation of the diameter of the tape wound on the reel, a microprocessor regulate the reel motor torque to maintain constant tape tension. Extremely high accuracy is achieved because reel rotation detection itself is carried out by counting the number of reel table pulses within a reference period set by the quartz oscillator frequency. A tension arm on the supply reel side provides the back tension needed. 

Technics has led the field in employing new FL meters as a more accurate and convenient alternative to needle type meters. Now in the M95 a newly developed professional quality FL meter with an extended indication range of -42dB ~ +8dB (30 segments: -6dB ~ +4dB are in 1dB steps; each of the other segments cover 2dB steps; for easier legibility, 0dB and above is a brighter red) is used. Timer start selector, record muting switch and feather-touch controls adds to the list of functions of this Professional Series deck while EIA rack mounting makes this deck a perfect match for the Professional 10000 Series audio components.
