12. USB Audio socket
This B-type USB socket is for the connection to a computer via a suitable lead
(not supplied).
This is for USB digital audio output and for connecting to the CAB RIG software.
Again, the signal for the digital audio will be derived from the actual speaker
output via the CAB RIG technology; providing a high-quality authentic mic’d cab
response. The actual sound is dependent on the CAB RIG switch setting and the
more in-depth settings within the CAB RIG software.
More on this in the separate CAB RIG documentation.
For USB audio, standard audio drivers are used to connect the amplifier to a PC,
Mac or other applicable recording device. No specific drivers are required.

NOTE:
Always connect the amplifier via a main USB port; often found on the
rear of the computer or side of the laptop. The amplifier will appear as an audio
capture device within recording software.
