Stereo Reel to Reel Tape Recorder (1973-78)
The Akai 4000DS is a four-track, two-channel stereo reel to reel tape recorder for use with 7" reels.
The employment of a highly efficient induction motor and boldly designed flywheel in the 4000DS results in stable tape travel and reduced wow and flutter.
This feature coupled with a three head system including Akai's one-micron gap playback head assures clear playback sound.
