When assembling or repairing audio amplifiers, it is not uncommon for it to be necessary to adjust the level of the signal supplied to this amplifier, while it is not always possible or desirable to organize a RG (volume control) on a potentiometer or discrete regulator. In this case, the module on the PT2256 microcircuit will help, which is an electronic volume control with 2 buttons: "+" and "-".
An additional "feature" of this RG is loudness, with a cutoff of up to 20 dB at a frequency of 1 kHz
Harmonic distortion factor
THD 0.01%
Signal-to-noise ratio ≥ 90dB
