With this volume controller, you can remotely control the stereo volume of your speakers. It connects via a mini-jack to mini-jack cable to the controller and via RCA cables to your speakers (cables included). This makes it ideal for controlling the volume of music and video playback from a PC or another audio device with a stereo mini-jack output.

It may not be widely known, but the best way to achieve undistorted sound from a digital source via the PC is to set the volume on the PC to maximum and adjust the maximum gain signal through an analog controller like the PC-1e. This configuration delivers a clearer signal, free from digital distortions and with the best signal-to-noise ratio.
