Using HD550 Direct Audio Inputs

HD550 users have the ability to plug in an XLR or ¼” audio input directly into their unit without the need for a USB adapter. 

Please note that these inputs support mic level audio signals only. If your audio equipment is line level, see here for a workaround.

When you plug in your audio source, be sure to add it as an audio input by navigating to the Inputs tab. Select Add Input > Audio Only. These inputs are the USB PnP Sound Devices.

You may notice a very low level of sound coming in. This low level of audio may appear regardless if your source is connected or not.

This white noise should not exceed -48dB on either input. It is characteristic of all USB-based PC audio devices and is virtually inaudible.
