DOLBY NR & DOLBY HX PRO

•The B/C-type Dolby NR Systems

Dolby NR systems are designed to reduce the amount of tape hiss,

mainly in the treble components. During recording, the high-

pitched pianissimo sounds which are most characteristia of

audible noise are boosted, and during playback, only these

boosted sections are attenuated, so that tape sound is returned to

normal. As a result, the noise is attenuated by an amount equal to the boosting in the treble range. The Dolby B-type NR system re- duces noise in the treble range, cutting tape hiss and expanding the dynamic range. The Dolby C-typeNR system is even more ef-

fective in reducing noise, as it reduces noise from the mid-range

on.

•Dolby S-type NR System

The Dolby S-type noise reduction system is effective at reducing

noise not only in the treble and mid-range frequencies, but in the

bass frequencies as well. In addition, maximum noise-reducing ef-

fect is demonstrated not only in non-recorded parts of the tape but in the recorded signal portions as well. The broad reduction of

noise modulation (bridging noise), freedom from dynamic side-ef-

fects in the audible spectrum (signal modulation) and reduction of decoding errors results in vastly improved sound quality.

NO TE:

When a tape has been recorded using the Dolby B-type, C-type or

S-type NR system, set the DOLBY NR ON/OFF switch "ON" and

then used the Dolby NR switch (BIC/S) to choose the system that was used during recording.

•Dolby HX PRO Headroom Extension System

The DOLBY HX PRO system controls the bias current during re- cording and maintains it at the optimal level based on the amount

of the high-frequency components in the music signal. It therefore provides excellent recording quality even when recording signals from digital sources, which contain a large amount of high-fre-

quency components. To guarantee optimal results, the HX PRO

system is activated automatically when recording begins. Since

this system controls the quality of recording itself, the clarity of

the sound will be maintained even when the tapes are played back

on another cassette deck which does not contain the HX PRO

Headroom Extension System.
