Commentary
This noise reduction unit commercialized the Dolby B type for the first time in the world.
The 100A has two separate sets of Dolby circuits for encoding and decoding.
By switching the mode switch, you can receive normal Dolby recording and Dolby FM broadcasting, and play music tapes recorded by Dolby recording and play back various kinds of recording such as dubbing.
The 100A is equipped with two sets of input level controls and two separate output level controls.
An independent source / tape switch is provided for both A and B channels.
It can also be used for monitoring and sound-on-sound on a 3-head deck.
The built-in modulation tone oscillator makes it easier to identify tapes during playback if you record this tone first during Dolby recording.
The case was sold separately.
