Delta Media Server for 10 Channel Audio Output using Focusrite Scarlett technology.

Delta Media Server: v2.2.38

Focusrite unit!)

Click Next to begin…

Note: if the file is stereo, it will only play out of 2 channels regardless of the configuration

Click and drag the file onto the timeline to test


Re-open Scarlett MixControl


Play the Timeline (Audio track)

The audio bars for each of the 10 channels should now move according to the output and if you bring up the Playback Window, you will see a green stripe in the bottom-left for each channel


Test Audio Output

Plug headphones into each of your 10 channel sockets at a time to check that the audio is coming through for each
