One of the classic systems from Optec. Optec is another brand that was owned by NESS. This is a Beam Scan System with 4 heads. Simple system that uses a single 4515 - 30 watt, 6 volt bulb in each head. The beam emits from the top of the fixture, through a color gel then onto a rotating mirror. The mirror reacts to the beat of the music. Units do not have an internal microphone, but instead they react from a signal that must be connected from an external audio source. This comes in from a regular audio RCA type connector. Each unit has 2 connectors which are internally wired together so there is no designation of which is in and which is out. The units daisy chain together with the 1st one connected to the audio source. Units were made in the US.
