Revision 1.2 - September 23, 2015
Introduction
JRiver Media Center is a popular audio playback application for Windows and Mac computers that supports multiple audio file formats, up to and including Direct-Stream Digital (DSD).
In order to use Media Center with the Geek Pulse digital-to-analog converter (DAC) to play music on Windows and Mac computers, it must be configured to send the appropriate signal data.
This document provides the steps necessary to install Media Center in Windows 7 and Mac OS X Mavericks, configure the Geek Pulse as the output device, and configure DSD playback.
This document assumes the Light Harmonic Audio Driver has been installed in Windows (no driver is required for Mac OS X) prior to this installation, and the Geek Pulse output device is connected and powered on.
If the Light Harmonic Audio Driver has not been installed, the installation file can be found on the LH Labs support page at:
