This volume controller module includes a PGA2310 TI, a high-performance volume control chip capable of maintaining the dynamic range of the signal, while greatly limiting the noise and distortion that could affect the playback quality of your audio system. The rotary encoder of the module allows an adjustment from -95dB to 0dB, with a step of 1dB. The module has its own design with voltage regulation, ELNA capacitors and an ALPS rotary encoder.
