reel to reel

The AKAI PRO 1000 from 1977 is a magnificient two-box rarity with impressive technical specifications that unfortunately didn't sell too well. The AKAI PRO 1000 features a 3-Motor/Double-Capstan tape transport system. For the capstan drive, this system uses an AC servo motor with a built-in CPG (Center Pole Generator) to provide smooth, stable operation while two 6-pole eddy current motors are emplyed for the left and right reel drives. Due to the high quality mechanism of this machine, tape speed deviation is +/-0.5% and wow and flutter is 0.025% WRMS at 15 ips. Excellent sound quality can be obtained at either 15 ips, 7-1/1 ips or 3-3/4 ips speed. The AKAI PRO 1000 is a four head, 2-track mastering machine that's as much at home on location as it is in the studio. A 2-track recorder will only record a tape one direction while the tracks are wider for higher quality. For further compatibility the AKAI PRO 1000 features beside the 1/2 track GX record and 1/2 GX playback head a 1/4 track GX playback head for compatibility with tapes recorded on 4 track recorders. Two large meters can be switched between peak level or VU meter but they can also be used as Bias Check display. Setting the meter changeover to Bias Check, the meters will indicate the amount of bias thus making the setting for various tape formulations extremely simple. The standard level (center click-stop) was calibrated to match Scotch #206 tape while the continuous adjustment for bias (+/-40%) brings out the full characteristics of every tape.

(said the advert) That's why, unlike other cassette decks, the Technics RS-9900US is a "cassette system". The world's first separation of a cassette deck into independent transport and amplifier units. The result is cassette performance that truly epitomizes cassette technology. With features in the transport unit lika a closed loop, double-capstan, 3-motor drive. A 3-head system. Pitch control variable by 10%. And full IC logic control of all transport functions for absolute freedom and tape safety in switching modes. With circuit technology in the amplifier unit like a separate direct-coupled record amplifier. DC reproduce amplifier. Headphone amplifier. Four independent Dolby processors. Complete with separate calibration for record and playback. Continuously variable adjustment of bias and equalization. Head azimuth adjustment. And internal 400 Hz and 8 kHz test signals. Track System: 4-track, 2-channel record and playback. 3 Motors: 1 direct-drive DC brushless capstan motor. 2 DC coreless motors for reel table drive. 3 Heads: 2 HPF heads for record/playback. 1 Ferrite head for erase. Frequency response (CrO2): 25-20,000 Hz (+/- 3 dB). Wow and Flutter: 0.04% WRMS. S/N ratio (dolby): 67 dB. Original retail price: $1,500. On the Japanese market this model was sold as Technics RS-690U.

cassette deck
Add caption

Nakamichi was at the vanguard of high-class cassette decks, providing the highest possible performance quality from every cassette while at the same time simplifying deck operation to make that performance available to everyone. The Nakamichi CR-7 and CR-5 Discrete-Head Cassette Decks embody both the vital aspects of this trend, offering fully discrete three-head designs, direct-drive closed-loop dual-capstan transports, low-distortion/low noise amplifiers and a host of other features. The Nakamichi CR-7 features the unique Nakamichi Auto Calibration System and the Playback-Head Azimuth Fine Tuning Control. While both decks offer superb value and can easily be integrated with the components of even the finest audio system in any home, they have been specifically designed to match the Nakamichi Home Audio Electronics Systems "7" and "5", for outstanding performance with the added convenience of total System Remote Control. Other features included are: real-time tape counter for C-90/60/46 tape - even if the tape is not fully wound to its begining when mounted, Dual-Speed Master Fader Control with Auto Fade function (tape end auto fade out), Wireless Remote Control (CR-7), Output Level Control, Headphone Terminal.
These cassette deck were built between 1986-1993 in three versions CR-70/CR-7A/CR-7E.
