* Note: The Microphone inputs along with the AUX input of the NS4FX are directly routed to the Master Output of the device (hardware operation) and they are not part of the USB Audio interface. Therefore they cannot be recorded, used for broadcasting or controlled in any way from VirtualDJ. The MIC level knobs are not sending any MIDI messages and cannot be mapped to any VirtualDJ actions.
