I do not hear my amp in my headphones/my DAW when I disconnect the cabinet

The Torpedo Captor X and Captor allows you to play your tube amp silently.
The Captor X has a headphones output, while the Captor needs to be plugged to a mixing desk or an audio interface to be played through headphones.

If you have no sound when you disconnect the cabinet from the Captor or Captor X in your headphones, this means the speaker cables coming in and out of the Torpedo unit are not connected to the right input and output. This is a very common mistake when using combo amps as the internal speaker has its own jack cable. Here is how to solve the issue (illustrated with the back of a Marshall JVM410 combo):

-turn off the amp.

- the internal speaker is connected to the amp through the circled cable. Disconnect this cable.

- connect an additional speaker cable to the output where the internal speaker cable was connected. Connect the other end of the additional speaker cable to the SPEAKER IN (red bolt) of the Captor / Captor X.

Your amp is now connected to the Captor/Captor X.
If you wish to use the attenuator, connect the internal speaker cable (highlighed in green in the image) to the SPEAKER OUT of the Captor X (SPEAKER ATT for the Captor).

For Fender amps like Hot Rod Deluxe or Deville, the speaker outputs are not as clearly labelled as in the previous example:

Disconnect the internal cable (highlighted in red in both images above).
As shown in the owner's manual of the Fender Hot Rod amps (https://www.fmicassets.com/Damroot/Original/10001/2231200_gamp_manual.pdf) , connect the additional cable to the output labelled V on the diagram.
You will connect the internal speaker cable of the amp to the SPEAKER OUT of the Captor X. This way you will be able to use the attenuator of the Captor X, send your amp signal to your audio interface or the PA. You will also be able to play your amp silently by disconnecting the internal speaker cable of the amp, that is connected to the SPEAKER OUT of the Captor X.
