Additional Details


By the early 1980’s the B-77, had reached its developmental peak with the mkIII and whilst this was a very good recorder, it was not in the ‘professional’ class. Rather than develop the B77 further, Revox came up with the derivative PR-99.
The entire electronics were optimised for extremely low distortion and high tolerances and the new PR99 offered, among other things: connection for automatic controller start from the mixing console electronic real time counter with zero and auto-locator vari-speed of -33% to +50% from the pre-selected nominal speed tape dump mode (for spooling tape into a waste-bin!) ready/safe switch (readiness/check function for inputs). adjustable clock-track function choice of high or low impedance microphone inputs. For hassle-free editing work the drive assembly cover could be raised to the front plate level.
The PR-99 came in a rack-mountable configuration but was also offered in either a portable or console version.
Other features included: integrated control logic with tape motion sensor which allowed any desired transition between different operating modes contactless electronic switching of all motors & remote control of all functions.

The Mk I was easily distinguishable by its mechanical counter, the Mk II featured auto-locator and brushed aluminum top and bottom face plate, and the Mk III sported a dark grey lower panel.
