Q-SYS Core 110f
USB Endpoint functions in Core 110f: Soundcard or
Speakerphone
Overview
A USB Type-B port on the Core 110f allows you to connect it to a PC, through a USB Type-A to Type-B cable,
and have it serve as a soundcard, a speakerphone, or both. (Do not try to use the Core’s USB Type-A host ports
for this purpose.)
Configuration
Before you can use the Core 110f’s USB endpoint functions, though, you must congure them in the Q-SYS
design. In Q-SYS Designer, open the design. Click on the Core 110f component in the Inventory Panel.
Under Core Properties, enter the number of endpoints you wish to have in the box USB Endpoint Count (up to four
USB endpoints).
Repeat the following procedures for each endpoint. Congure each endpoint as either a speakerphone or a
soundcard; a speakerphone is typically used for teleconferencing, whille a soundcard is typically used for media
playback, presentations, or multitrack recording. You can have soundcard and speakerphone endpoints simulta-
neously in the same design.
To configure a soundcard endpoint
1. In the Type list, select Soundcard (for multitrack recording or playing back audio
through or from the PC). See Figure 1.
2. Congure these additional parameters:
• In the Input Mode list, click Line (for playing audio from streaming apps
and sites such as Pandora, Spotify, et al, or for multi-track recording, for
example) or Speaker (for multi-channel playback, for example). The term
“Input” is from the Core’s perspective, and it represents audio output from
the PC.
If you selected Line, congure these additional parameters:
• In the Input Count list, click 0, 2, 4, 6, or 8. By default, Windows can
handle only the rst two channels. For more than two channels, install
Figure 1. In this example, End-
point 1 is congured as a 5.1
surround audio input for the Core;
Endpoint 2 is congured as two
input channels and two output
channels.
