How to use a Captor X / Captor with a Vox AC10
The vox AC10 C1 has a External Speaker output at the back of the amp. It is a 16 ohms output.
When it is connected to a cabinet or a load box, the internal speaker is muted.
Connect the Captor x (16) or the Captor 16 to the External Output of the Vox AC10 to use the amp silently and send the amp signal to your DAW or the PA.
Here is the owner's manual for the Vox AC10.
