Christmas Tree FX

It's easy to change your regular garden-variety Christmas lights into a fascinating light show. This FX unit requires no special installation--simply plug your Christmas tree lights into the back of the box. Turn the unit on, and adjust the sound sensitivity dial as needed. Thanks to the built-in audio pickup, the lights will brighten, twinkle and pulsate in response to music and other noise in the room. It's a different presentation every time the music changes. Also has an audio input option if you wish to have it respond to only one sound source. Safe to use on strands with flasher bulbs. For use with incandescent lights only, will handle up to 500 watts total. Includes instructions and extra fuse. About 9" x 7" x 4".
