Additional Details
Description
The A807 was the final analog recorder Studer produced. It uses the high quality phase compensated electronics of the A810. The A 807 was offered with the many options that are outlined below. The Frequency Response, Wow and Flutter & Signal-to-Noise Ratio specs seem restrained, conservative or poor for a machine of this stature. The A807’s were often used as auxiliary machines in studios, so the chances of finding one in good condition with longer head life etc. are better than many of the bigger studio machines.
