DYNEQ circuit (Dynamic Equalization; Tandberg Audio Patent) for improved tweeter control of the tape. Avoidance of band saturation in the high-frequency range.
Play trim circuit (NAD /Dolby-Laboratories development) to compensate for high-frequency errors during playback caused by band saturation, incorrect bias setting, equalization differences or head azimuth. Due to these errors, the Dolby noise reduction does not work properly and leads to dull sound. The play trim circuit helps to ensure correct playback here. On the front of the device there is a rotary potentiometer for the Play Trim circuit (range ± 5).
