Glossary
ATS
Automatic Tape Selection. The tape deck automatically sets the
appropriate equalization characteristics and bias current
according to the type of tape inserted in the deck.
Automatic calibration
The automatic adjustment of the bias current and recording
level for the inserted tape.
This adjustment works together with the deck's ATS
(Automatic Tape Selection, see above) to get the best possible
recording results on any tape.
Dolby HX PRO system
A system that reduces distortion and noise in high-frequency
response during recording. A tape recorded with this system
produces the same high-quality sound even when played on
other tape decks.
Dolby NR (noise reduction) system
A system that eliminates tape hiss noise by boosting low-level
signals in the high-frequency range during recording, then
lowering them during playback.
There are four types of systems: A, B, C and S (provided on
TC-WR665S only). Type A is for professional use (not available
on your tape deck), and types B, C and S are for consumer use.
Type S has the maximum noise reduction capability, followed
by types C and B.
Multi-AMS
Multi-Automatic Music Sensor is a function that locates the
beginning of up to 30 tracks before or after the current track by
detecting the blank space (of over 4 seconds) between tracks.
Multiplex filter
A filter for eliminating the 19-kHz stereo carrier and the 38-
kHz sub-carrier signals that may impair the Dolby NR system.
Though tuners are usually equipped with this filter, if you got
poor results when recording FM broadcasts with the Dolby NR
system, your tuner may not have a filter or the filter may not be
working. In this case, set the DOLBY NR switch on the tape
deck to FILTER ON.
Test tones
Signals (Ifl-kHz and 400-Hz) generated by the tape deck for
bias current and recording level calibration.
