AVT2742 A

A frequently performed and incredibly popular device allowing to visualize the sound by playing different colored lights. The big advantage of AVT2742 putty is the lack of voltage circuits. In the iluminophony, sets of differently colored LEDs have been used. It is also not necessary to interfere in the output circuits of the amplifier and loudspeakers - the acoustic signal is drawn from the environment by a small electret microphone. The system has a gain adjustment in each channel and an additional regulation of microphone sensitivity. The set is very easy to assemble, no complicated tuning is necessary. More demanding people can use triaks as output systems. Then, the iluminophony will be adapted to control typical incandescent lamps and will be perfect at the disco.

The device is especially recommended for those who like 'colorful' sound reproduction and for all lovers of disco light effects
