The previous music-controlled disco light controllers, the audio-controlled disco light controller circuit and hi-lo (treble-bass) disco light controller have some features and drawbacks. The first one features high voltage drive, enable the circuit to drive 220VAC lamps, and the drawback is that it has only one way (single channel control). In the other side, the second version has two-way (bass […]

Using high (treble) and low (bass) frequency beat detection to control stage lamps can produce automatic light jockey for disco or any music performance. Instead of using general level of music signal to control a disco lamp, the circuit presented here uses two separate channel to give more complex variation of light flashing pattern. The dynamics of music signal is […]

Using some active and passive components, we can build a simple audio-controlled disco light controller circuit. A standard audio power amplifier output, which usually drive loudspeaker, can used to drive this disco light circuit. With this circuit we don’t need light jockey anymore, because the flashing of the light will be directly controlled by the music signal itself. The schematic […]

Introduction to Automatic Disco Light Control Simple audio or music controlled disco light uses comparator to sense the beat of a music signal, but this comparator has a reference point that should be calibrated according to the music signal volume. It’s easy if we have a light jockey to take the duty of controlling all the lighting, but it’s not […]
