AVT1466 A

The most important application area of the presented system is, above all, the fun. Nevertheless, the 'echo' parameters are so good that it can find quite serious applications in electroacoustics. The 'heart' of kit is a specialized integrated circuit. It contains all the elements of the audio track and a digital delay line. The system works in a typical application with element values specified by the manufacturer. To expand the possibilities of application, a mic together with a matching amplifier was added to the board. As a result, a device was obtained that can transmit sounds from the surroundings or be directly connected to the audio track of any amplifier.

The device is especially recommended for people who like to 'play' with sound, electroacoustics
