AVT5283 A

Projects of all kinds of electronic potentiometers are a frequent topic of many practical solutions. It is connected with still used playing equipment equipped with traditional mechanical potentiometers. The sound effects resulting from their age often are an incentive motivating to modify the audio track and always affect the listeners and the way of receiving the messages.
The simplest method is to use electronic potentiometers. Their presence in the playing equipment guarantees two important things - an acoustic track devoid of characteristic glitches and comfort - the possibility of very easy expansion with remote control

The device is particularly useful in audio systems and for modification of existing devices
