Dolby HX-Pro and DYNEQ: 

Dyneq varies the record equalization to prevent over saturatio when strong high frequency transients occur. HX PRO varies the bias supplied to the bias supplied to the tape during recording to maintain optimum high frequency at all times, thus making a much more accurate reproduction of your source. Note:  HX-pro and DYNEQ are compatible for playback with all cassette decks, including car decks.

Car Circuit: 

Boosts quiet passages in the music without altering the loud passages, making a more practical tape for car or portable players. It also adds equalization for the car environment.

Play Trim:

Developed by Dolby laboratories with NAD, Play Trim compensates for high frequency loss before Dolby NR, restoring highs withput increasing noise. Example: Take an old tape with dulled highs and turn the Play Trim knob and note the restored highs.
