Computers can be connected using a USB-A male-to-USB-B male cable. The USB-A connector
is connected to the computer’s USB jack and the USB-B connector is plugged into the USB input.
The USB input is selected by pressing the USB input selector button on the app. Operation is
automatic when connecting Apple computers running macOS to the digital module. When using
a computer running Windows OS, bridging software and Windows driver software will need to
be installed. A simple solution when using a Windows PC is to install the Roon Labs music player
software (subscription required) and the digital module’s Windows driver. JRiver software is also
a good option when using Windows PC. Please visit the Relentless Preamplifier product page at
www.dandagostino.com
for additional information on connecting a Windows PC to the Relentless
Preamplifier and to download the required Windows driver.
