The compact design of the A807 makes this recorder the ideal working tool in the broadcasting sector, whether stationary or mobile. The drive is based on a robust die-cast aluminum chassis. Direct-drive, servo-controlled winding motors with high torque guarantee high winding speeds as well as rapid acceleration and deceleration. Capstan drive with brushless precision DC motor for quick start-up and synchronization. In addition, there are: microprocessor-controlled drive and audio electronics, three tape speeds, shuttle wheel for easy maneuvering, and the standard equipment with parallel and serial interface (RS232); phase-compensated, digitally controlled audio electronics - without matching potentiometer; versions with built-in 48 V microphone phantom power (12 V phantom power as an option), 300 mm winding plate with 1000m tape and a wide range of accessories: drive remote controls, Varispeed controllers, transport cases and transport aids, studio consoles and various superstructures.

A STUDER A807 can be easily and relatively quickly calibrated to the desired values. For this you need a sharp object such as a ballpoint pen refill. This is carefully inserted into the small opening labeled "Adj". The button located in the opening then automatically switches to the calibration mode. Now you can determine the desired values. The "Lap", "Set" and "Sel" buttons are now used to select the different modes. The "Loop" and "Loc Start" buttons are now used for value selection. The changes are then saved with the "Step" button. You can exit the menu again by pressing the "Adj" button. Further information on this topic can also be found in the manual.

The STUDER A807 is certainly one of the most sold products from STUDER. More than 10,000 (!) Units sold. The A807 will be and will remain in good memory, especially for the many broadcasting users worldwide. At least for the next few years, the procurement of spare parts is also guaranteed, as I was personally assured by a STUDER technician on telephone request...

End of production
- The STUDER A807 was the last tape recorder ever manufactured at STUDER. With this model, the traditional production of belt machines was discontinued at STUDER in the summer of 2001 after more than 50 years.
- Due to the great demand at that time, a limited edition of the A807 was launched on the market again in December 2002 – but that was finally the end for this tape recorder, which was very popular with customers.
- The A807 was advertised in the STUDER general catalogue from the year 2000. At that time, the eight versions mentioned above were offered
