Glossary

AMS

Automatic Music Sensor. A function that locates the beginning of a track by detecting a blank space of over 4 seconds between tracks.

Memory Backup

Function for storing tape deck operating parameters after the power is turned off. The memorized parameters are:

—linear counter and counter memory parameters

—MPX FILTER, Dolby HX PRO and MONITOR settings. To reset parameters to their original factory settings, turn on the tape deck while holding down both RESET and RREC MUTE.

ATS

Automatic Tape Selection. The tape deck automatically sets the appropriate equalization characteristics and bias current according to the tape type inserted in the deck.

Bias calibration

Adjustment for optimum recording. You can get better recording results with minimum distortion and flat frequency response by adjusting the bias current to the appropriate level. Lowering the bias current can boost high-frequency response, but also cause higher distortion. On the other hand, raising the bias current can minimize distortion, but also reduce high- frequency response. To balance both the bias current and high- frequency response, it is necessary to adjust the bias current appropriately.

However, to suit your taste, you can also adjust the bias current as you want.

Dolby HX PRO system

Distortion and noise reduction system. The Dolby HX PRO system reduces distortion and noise in high-frequency response while recording. A tape recorded with this system brings the same high-quality sound even when you play the tape on the other tape decks.

Dolby NR (noise reduction) system

Noise reduction system for eliminating hissing noise. The Dolby NR system boosts the low-level signals in high frequency during recording and restores them during playback.

There are 4 types in the Dolby NR system: A, B, C and S. A-type is for professional use (not available on this tape deck), and B, C and S-types are for consumer use. S-type has the maximum noise reduction capability, followed by C and B.

MPX filter

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. Usually the tuner has an MPX filter. If you cannot get a satisfying result when recording FM broadcasts with Dolby NR system, your tuner does not have a filter or the filter is not working. In this case, set the MPX FILTER switch on the tape deck to ON.

Recording equalizer calibration

Adjustment for optimum recording. Use the REC EQ control to adjust the equalizer to suit your taste. Turning the control clockwise emphasizes the high and middle frequencies; turning the control counterclockwise reduces the high and middle frequencies.

Recording level calibration

Adjustment for optimum recording. Even when you have adjusted the recording level correctly, the playing level might turn out to be low depending on the tape used. By adjusting the recording level calibration, you can compensate for the low recording level. When you record on a tape with the Dolby NR system, this function works more effectively.

Tape counter

A display element that shows the elapsed recording or playing time as a digital readout. Since the counter is not a digital clock, the displayed value will differ slightly from the actual elapsed recording or playing time. The counter value also includes the length of the leader tape.

Test tones

15-kHz, 3-kHz and 400-Hz signals produced by the tape deck when you do the bias, recording equalizer and recording level calibration.
