Comments: The Lo Gain In jack allowed a high output device to be inserted into the signal path. This jack functions much like the modern day equivalent of a "Power Amp In" The Dual Professional used two output transformers mounted to the speaker frames. The Dual Professional included two 10" Jensen speakers. It was renamed the Super in fall of 1947.
