I picked this up the other day, for free. (Pictures to follow.)
It's a composite-video/analog-stereo-audio distribution amplifier, with two inputs & ten outputs. A front-panel selector switch assigns all ten outputs to input A or B, or 1-5 to A & 6-10 to B. Aside from a burned-out light bulb in one of the front panel level meters, it seems to be A-OK.
Now to figure out how to use it best!
