Compared to the Harman Kardon AVR 75, it has an additional Stereo RCA pair labeled "Multi Out".

From the Service Manual:

Multi: This indicator signifies that the AVR85 is sending a program source to a remote room location. Note that it may be illuminated even when the unit is “off” in the main listening room, signifying that operation continues at another location. When a remote command is being received via the Multi IR connection (59), this indicator will flash. NOTE: this feature differentiates the AVR85 from the AVR75. The AVR75 does not have this feature.

Pioneer PM4007A is used for AC3RF demodulation.
