Dolby Hx Pro; Care And Maintenance - Tascam 122MKIII Owner's Manual

Dolby HX PRO
If the source you are recording is rich in high-frequency
signals, they can adversely affect the accuracy of the
recording and decrease the high-frequency response. The
Dolby HX Pro system takes care of these signals during
recording to prevent the accuracy of the recording from
decreasing and improve the high-frequency response (by 6
dB or more).
The Dolby HX Pro system uses no encoding/decoding
process and a cassette tape recorded with this system can be
played back on any stereo cassette players.
