Noise Reduction Unit (1972)
The TEAC Dolby Noise Reduction System will enable you to make superior recordings at reduced tape speeds.
A prime reason for using the higher speeds was to reduce tape hiss, with the AN-80 tape hiss is electronically reduced in amplitude so that it is no longer a limiting factor in tape quality.
You will find that your slow speed recordings equal or surpass those you made in the past at higher tape speeds.
The Dolby System operates by processing the signal as it is fed to your tape recorder. Upon playback, the signal is unprocessed or returned to its original state.
Therefore the Noise Reduction Unit is connected into your audio system between your tape deck and the recording source, be it an amplifier, pre-amp or receiver.
