Technics designed the RS-9900US in two components for one reason: To outperform all other cassette decks. (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.
