The ePotPi.V4 is a software driven electronic stepped attenuator and preamp controller, that when equipped with appropriate power supply and OLED display module can function as a  full featured, remote controlled passive preamplifier, and when equipped with an optional solid state buffer board, can functions as an active preamplifier. Like all Tortuga Audio preamp controllers, the V4 employs light dependent resistors (LDRs) as the sole means for for audio attenuation (volume control). No mechanical potentiometers or switched mechanical attenuators are used. The V4 represents the 5th generation of Tortuga Audio LDR based passive preamp attenuator and controller and builds on work that began over 15 years ago.
