Labsound 770 "3D-sound expansion interface?"

Postby Tyrantulas » 2017-10-11 @ 19:32

I recently came across a generic looking ESS1688F based ISA sound card that I wanted to start doing some experimentation with. I was able to do some identification with FCC data, and learned it is a "Labsound 770." Some quick Googling netted me the jumper settings for the card... and a new question. There is a header on the card labeled CN3 called the "3D-sound expansion interface."

Any idea what that was originally for?

Currently, there are a couple of jumpers in place on the connector (I'd assume disabling the port)

Possibly for 4-speaker support using a daughterboard that is attached to a free slot cover space?
