This is the top of the line reel to reel model made by Teac. It's 4 tracks 2 channels in quater inch wide tape and can hold reels until 10.5" (26.7 cms.).
It has 6 heads (cobalt amorphous record and playback), fully bi-directional, 3 motors and dual capstan drive system (belt driven).
Two speeds, 7.5 ips (19 cm/s) and 3.75 ips (9.5 cm/s), electronic real time counter (hour, minutes and seconds) and fully tension servo control, which means that you can use any size of reel without adjusting the tension manually by a switch.
Was produced in silver and black:

It's one of the few machines that has a built-in decoder/encoder dbx type I professional noise reduction system. Other rare feature is that the machine can use "EE" tape (Extra Efficience = CrO2). I think that only Maxell, Akai and Basf produced "EE" tape.
The transport function is computerized and has functions like return-to-zero, return-to-cue, program, repeat, set-cue and reset the counter.

It's said that the Teac X-2000R maybe is the best consumer machine ever made, but for me it has at least one disavantadge: the use of lifters in the tape path to separate the tape of the heads during FF and RWD.
UPDATE
TDK also produced "EE" tape, which was labeled as "SA". Akai never produced his own "EE" tape, really the chrome tape inside Akai reels were produced by Maxell (XLII).
Thanks to Frank Oomen for the correction.
