Teac 450 - Page 2

*
Note:
The teac 450 with the widely acclaimed Dolby Noise Reduction System re 
presents a quantum increase in cassette sound quality, bringing you recording quality,
features and performance to equal or surpass that of high quality open reel recorders.
Until this time the quality of cassette recordings was limited by the inherent noise of
the tape itself. The revolutionary Dolby System, although commercially available to
and in use by almost all major recording studios, was not available to the home tape
recordist.
The Dolby System as incorporated into the teac 450 operates both during
recording and playback. During the recording phase, low amplitude high frequency
signals are expanded by a precise amount, during playback they are compressed by
exactly the same amount by a mirror image circuit. By this process all noise from
both the cassette electronics and from the tape is eliminated or reduced to an
inaudible level. This entire process is accomplished without in anyway affecting the
original sound quality, since no attenuative filtering is used. The original signal is
reproduced with true fidelity but without annoying tape hiss or amplifier noise.
