The TEAC Z-7000, Z-6000 and Z-5000 are Masterpieces in cassette reproduction technology introduced in 1985. Here are some higlights of the incorporated technology. For high transport performance the Z-Series transports are all constructed on a solid diecast chassis - highly resistant to vibration, resonance and warpage. In the Z-7000 and Z-6000, three independent high precision motors are built onto this chassis: an FG servo brushless direct drive capstan motor and two coreless direct drive reel motors operating in a dual capstan closed loop system. The Z-5000 achives similarly high performance with a two-motor transport consisting of one direct-drive motor driving a single capstan, and an independent DC motor powering the reels.
In the Z-7000 and Z-6000 the playback head is a top-precision ferrite design, while the recording head is formed of sendust. The Z-5000 offers essentially the same three-head system, but with TEAC original hard permalloy formulation. Perfect record bias, level and EQ are obtained by the Z-7000 with an automatic calibration system while the Z-6000 and Z-5000 feature a precise manual calibration system. All decks feature Dolby B, C and dbx noise reduction circuits. Real-time tape counter, 30-sement fluorescent peak level meters (14 segments in the Z-5000) and a series of convenience and sound features are also included for tape enthousiasts.
