AVT2743 / 1 B

An extremely effective disco device. Despite the use of the three cheapest and very popular integrated circuits, a very large number of lighting effects were obtained - thanks to that, the use of a microprocessor became unnecessary. The system enables the generation of color flashes in both music and rhythm of the built-in variable frequency generator.
The device consists of two main blocks. The analogue is used to amplify, filter and form into the impulses sounds coming from the environment and received by the microphone. The digital part responds to these impulses, it turns on the light fields in the appropriate sequence. The system is completely separated from the mains.

The device is especially recommended for discos, colorful music lovers and light effects enthusiasts

Selected parameters of the controller:

• sound control or a built-in generator
• built-in microphone
• regulation of the acoustic signal level
• ten half-light ones
• light sources - LED diodes, the possibility of using car bulbs
• pulse length adjustment from the generator
• various light effects, e.g. stroboscopic effect, wave
• effects coding - jumpers
• power supply - 12 V
• in the set of printed circuit boards (main + 1p.m. LED matrixes), a set of elements with red super-bright LED diodes and documentation
  Attention. Additional LED matrix plates are available under the / 2 mark
