Using the USB-C audio inputs and outputs on the StudioEdge

Scope

This document covers the use of the USB-C audio inputs and outputs on the back of the StudioEdge, as indicated by the on this image.

The USB-C Audio Interface

The USB-C sound device on the back of the StudioEdge is a plug-and-play audio adapter that connects to laptops, tablets, or smartphones with USB-C ports, allowing you to send and receive sound. No special drivers are required. Each port on the back of the StudioEdge is a single-channel device. When connected to your device, it will appear as “USB AUDIO CODEC.”

Device listings are similar on Windows and Linux. Check your device for support with a generic USB-C sound card. Telos does not offer drivers for specific devices, so if a driver does not work on your device, then a generic USB sound card is not supported by your device.

Note that no changes are required for Mac; however, on Windows you must change the Default record format.

Support for Windows

Windows will default to 2 channel, 16 bit, 44100Hz (CD Quality). You must change this to 2 channel, 16 bit, 48000Hz (DVD Quality)

1. Select your USB AUDIO CODEC device on the Recording tab of your Sound Properties.

2. Click the Properties button.

   

3. Select the Advanced Tab and set the Default Format as shown here, then click OK.

Configuration of the StudioEdge

Two USB-C connections are on the back of the StudioEdge, labeled IN/OUT USB 1 and IN/OUT USB 2. These devices SHARE resources with AES/EBU I/O 2 and 3, respectively (labeled Digital 2 and Digital3 on the web UI and Front Panel.

For some additional clarification.

• Digital 2 can be AES/EBU IO 2 OR USB I/O 1

• Digital 3 can be AES/EBU IO 3 OR USB I/O 2

Is it impossible to use all three AES/EBU I/O and both USB I/O 1 and 2

Configure Digital 2 and 3 from the Front Panel or the web UI
