What is DBX?
DBX is a noise reduction system similar to Dolby B, C, and S, but uses the same compression on all frequencies, high and low. However, DBX is mostly used in the professional market. Very little home DBX equipment is available, and some of that home equipment is no better than comparable Dolby B home systems. All DBX systems are compatible with all other DBX systems, but incompatible with Dolby. A DBX tape will sound terrible without DBX processing during playback. (courtesy of AudioFAQ)
What is HX-Pro?
Dolby HX Pro is not noise reduction and does not use compression or expansion. HX Pro is a technique developed by Dolby Labs to increase tape headroom by decreasing the bias when recording signals with a large high frequency component. This allows better transient response, particularly on less expensive tapes, and requires no processing when the tape is played back. Dolby HX tapes can be played back on any system with no decrease in quality. (courtesy of AudioFAQ)
How do I clean tape heads?
To clean tape heads, use pure isopropyl alcohol and lint-free swabs. Throw the swab away after use.
How do I demagnetize tape heads?
Practical tape head demagnetizers are available for under $10. Try to find one with a plastic coated tip. If you can't find one which is plastic coated. you can slip a drinking straw or plastic tube over the tip for the same effect. This plastic will prevent the demagnetizer from scratching the head.
Before plugging in the demagnetizer, remove all tapes from your working area and unplug the recorder. Hold the demagnetizer away from the recorder as you plug it in. Slowly bring the tip of the demagnetizer up to the tape head and slide it back and forth across each tape head for five one-second strokes. Then pull it away from the head slowly and go on to the next. After demagnetizing the heads, use the tip on each metal tape guide with a similar five strokes. Last, slowly pull the demagnetizer far away from the recorder and unplug it. Recording engineers use a demagnetizer before each recording session. (courtesy of AudioFAQ)
How does bias fine tune work?
The bias fine tune only changes the sound during the recording process. Variable bias is a compromise to adapt the deck to different tape brands. It is most useful for type 1 (normal) tapes. You make a recording, and then compare in playback to the source. If the recording sounds bright, turn the bias knob clockwise 30 degrees and make another recording. Dull? Turn the knob counterclockwise. You can also test by recording FM inter-station hiss, but keep Dolby off and keep record levels at about -20dB. (courtesy of Tom Brucker)
While listening with my headphones the volume is way too loud, how do I adjust that?
Try to adjust the output level control. It's on the front panel.
What is bias?
Bias is the amount of energy transferred to the tape. As tiny amounts of head wear begin, the tape gap grows slightly larger. It is therefore necessary to adjust so the proper amount of energy is transferred in order to maintain proper high-end response while maintained low THD. (courtesy of Nakamichi Cassette Deck FAQ)
What is level calibration?
It is the setting that assures that the level you record on tape in the record (source) mode is what comes back on play (tape) mode. Differences develop as uneven head wear occurs. Depending on use, an annual calibration is an excellent idea. (courtesy of Nakamichi Cassette Deck FAQ)
Closed-Loop Dual Capstan Transport?
A closed-loop dual capstan transport mechanism ensures smooth, precise tape traveling and as a result excellent sound reproduction.
