The Nakamichi ZX-9 Cassette Deck is a very special analogue recording/playback audio component. The ZX-9 cassette deck is an enhanced version of the well-regarded and acclaimed ZX-7 deck which was introduced by Nakamichi during 1982. The ZX-9 has completely manual calibration controls, including adjustable recording azimuth and bias, extra durable tape transport system with dual capstan drive, and discrete record/monitor/playback head system. The ZX-9 cassette deck has some of the most precise technical specifications Nakamichi ever designed into a commercial cassette deck! This is an exceptional machine, one of Nakamichi's finest and cost effective when considering a $1,500 retail price during the early 1980's!
