Sunn Fender PLC 816 + 2x PS-1200 1980 Black

This is a Sunn (now Fender) lighting control system from the 1980s.  Works fine, has cosmetic blemishes (missing a few buttons, paint scratches).  It consists of three components:

1 x Sunn Model PLC 816 control panel
2 x Sunn Model PS-1200 Dimmer Control boxes

It can control up to 8 different light fixtures (4 each Dimmer Control Box).  Incorporates a wide variety of lighting functions (chase, fade, flash), scene and song set up, audio sync, MIDI control, etc.  Connections are made with standard audio XLR cables.  Control panel is powered by the dimmer boxes thru the XLR cable.

Manual included for the PLC 816 (WORD & PDF format). The Dimmer Control Box manuals are non-existent but you really don't need one except to set the controller address DIP switches (and I taped a listing of all possible settings on each box).

We've used these with 8 x 100W floods and it provides more than enough light for the typical band

I do not believe this is compatible with DMX.  From what I have read online, it uses a proprietary protocol, and is a self-contained system.  You just need to plug in light fixtures.
