If it helps, the ZIP file mentioned in my previous post contains a schematic of the Pan Rotate unit. The schematic is dated 1985 so, as Fons points out, the processing is unlikely to be sophisticated. For more sophisticated processing, read the following AES preprints: M.A. Gerzon, "The Design of Distance Panpots", Preprint 3308 of the 92nd Audio Engineering Society Convention, Vienna (1992 Mar.) (Simulating distance effects in directional reproduction.) M.A. Gerzon, "Signal Processing for Simulating Realistic Stereo Images", Preprint 3423 of the 93rd Audio Engineering Society Convention, San Francisco (1992 Oct. 1-4) (Use of DSP methods for simulating images realistically placed in a virtual space, including distance and image-size simulation. Based on psychoacoustic methods rather than on physical modelling simulation.) These preprints are listed in the Bibliography at: http://martinleese.epizy.com/Ambisonic/bibliography.txt The annotations are by Michael Gerzon.
