INTRODUCTION TO THE ML1 MUSIC LIGHTS KIT One of the most popular effects to be found at music fests and concerts has to be the Color Organ, better know as Music Lights. A set of music lights will control an array of lights in a dazzling display of never ending, fascinating patterns. While not as elaborate or expensive as its professional cousins, your ML1 is just as hard working and just as fine.

ML1 CIRCUIT DESCRIPTION The ML1 is similar to a common mounted light dimmer, except that the lamp control comes from the voltage derived from the music rather than a potentiometer. The control voltages come from three separate, simple audio filters which break the audio spectrum into individual frequency bands. Audio signals from the speaker input are current limited by R1 and applied to transformer T1.

Now that all the ‘landmark’ components are installed, we’ll go about putting in the smaller parts. These components are spaced close together on the PC board, so pay close attention to the layout diagram so you install the right parts the first time! Also, we’ll ask that you remember that install means to not only install the part, but to solder it and trim the leads as well. 5. Install the three stand-up resistors, marked L1, L2, and L3 on the PC board. 6.

Mount your selected AC outlets to the rear of your case. Install your AC line cord through a suitable hole and strain relief device ( a grommet with a knot tied in the cord inside the case or something similar). Select a convenient location in which to mount your finished PC board, but do not install it yet. Drill or punch the appropriate mounting holes for the PC board and make clearance holes for the controls.

Using the ML1 Within the Home The most popular use of the ML1 is to hook it up to your stereo and produce an enticing light show. This is especially nice during the Holiday season, controlling Christmas tree lights on the house or tree from a selection of seasonal music. Party atmospheres are also enhanced by such a display. But, how about some unique ideas? One customer uses it in a speech class to help speech students see what words should look like. Another uses his ML1 to ‘see’ the phone ring.
