I have a guitar amp sim (line-level) hooked up to a Quantum. With no DAW open, I hear a low level signal coming out the monitors, connected to the main outputs. It's also clearly visible in the inputs in Universal Control, but not at the outputs. The same on the front panel of the Quantum.
In the DAW, I have a double sound.
To me, it sounds like hardware monitoring, but the Quantum doesn't have that, I know. So what's wrong here? How do I get a quiet Quantum with the DAW off?
