Direct-drive, servo-controlled winding motors with high torque guarantee both high winding speeds and rapid acceleration and deceleration. Capstan drive with precision brushless DC motor for rapid ramp-up and synchronization.

Studer A807 calibration[edit]
A STUDER A807 can be calibrated easily and relatively fast to the desired values. To do this, you need a pointed object such as a ballpoint pen refill. Carefully insert it into the small opening marked "Adj". The button in the opening automatically switches to the calibration mode. Now you can determine the desired values. The buttons "Lap", "Set" and "Sel" are now used to select the different modes. The buttons "Loop" and "Loc Start" are now used for value selection. With the button "Step" the changes are stored afterwards. The menu can be exited by pressing the "Adj" button. Further information on this topic can also be found in the manual.

Reviews[edit]
- The STUDER A807 is certainly one of the most sold products from STUDER. Over 10,000 (!) units have been sold worldwide. The A807 will be and remain in good memory especially for the many radio users worldwide. At least for the next few years, the procurement of spare parts is guaranteed, as I was personally assured by a STUDER technician on the phone...
- End of production
The STUDER A807 was the last tape recorder ever produced by STUDER. With this model, the traditional production of tape machines was discontinued at STUDER after more than 50 years in the summer of 2001. Due to the great demand at that time, a limited edition of the A807 was put on the market again in December 2002 - but that was the end for this very popular tape recorder. The A807 was still advertised in the STUDER general catalog from 2000. The eight versions mentioned above were offered at that time
