Advent Corp Acoustic Phase switching unit

A friend picked this up recently and I know nothing about it. Wondering if anybody knows anything.

Pro audio for adding EQ's and lights with speakers?

It's an A/B speaker selector switch used in retail stores to demo pairs of speakers. The lamp connections were to turn on small indicator lamps by each speaker to indicate which pair were being currently played. The screws above each toggle switch were to raise or lower the volume to closer match the volume of the 2 speaker pairs being compared. This really required a test tone and spl meter to be accurate, most places I saw them in use the sales people had no clue how they worked and usually just cranked them all the way up...idiots.
The jack located on the lower left corner of the faceplate is where the the push button switcher plugged into to switch from pair A to pair B. You can also use it to switch between different equalizers and 2 different amps.
Nice piece actually.
