Hi @vermouth13
Ross from Two notes here! Thanks so much for reaching out!
If you are talking about Captor X you will need to use the included power supply to power the unit. Then, connect your amp's output to the SPEAKER INPUT of the Captor X, indicated by a red bolt - ONLY use a speaker cable for this connection. Connect your headphones to the PHONES output if you want to monitor privately. Use the OUTPUT LEVEL to set the level of your headphones. If you want to listen through monitors or record to your DAW, connect the XLR outputs to your studio monitors/active speakers/audio interface with microphone cables. You can also use XLR/TRS jack from the Captor X's outputs to the next audio device. The OUTPUT LEVEL controls both the headphones and XLR outputs.
Let me know if you need a similar description for our Analogue Captor!
