Description
Product Resume
It is a digital controlled stereo electronic audio volume control designed for a wide range of audio amplifier projects and audio applications such as Jukebox, kiosk, Desktop, tec. Being a family member of Wondom Volume Control Series, it features easy installation and convenient connection. Add it to any amp board that has line input capability to control the volume with a stepped rotatory knob. Analog and digital sections receive power independently to minimize the chance for interference.
