Special Features
- Further development of the well-known HMK-D200. Essential innovation:
- Calibration computer for fine tuning to tape type. Was originally planned with a 3-head variant, could have recorded there in one run test signals and listen to / evaluate the result. A/W composite head would have had to be imported for foreign exchange, this was omitted for the consumer devices and only for special industrial devices (CAW, among other things for Ministry for State Security and German Reichsbahn as train radio logging machine). Thus, the calibration computer was realized with multiple rewinding and listening to the test recording, comparable to the Pioneer CT-447 (1991). At least pre-magnetization (bias) and band sensitivity (pickup amplifier) were apparently calibrated for correct operation of the compander system. The calibration circuit required an additional board ("ABE" - automatic band calibration) in the unit, the software part was already in the ROM mask of the microprocessor also built into the HMK-D200, but is deactivated in these units.
