The audio signal of these sources will be routed to the Master Output in the following cases. - VirtualDJ (or other supported application) is not running (stand-alone) - VirtualDJ is running, the PMX20 is set to Hardware (Mixer) mode and the USB buttons are turned off - VirtualDJ is running with Timecode inputs set in Audio Setup (signal of the Timecode sources) will be muted from output and will be routed to VirtualDJ for DVS control.39 PH/LNSet these switchers to PH position if you have connected devices to the CH1-CH4 inputs respectively, without pre-amp such as Turntables. Set to LN position in other cases.40 MIC INConnect a Microphone to this input, using XLR or 1/4" cable/adapter. The level of the Microphone audio signal is controlled from the MIC LEVEL knob at the top panel. Note that this input is not part of the USB Audio interface, thus the Microphone of the PMX20 cannot be included in the VirtualDJ Audio setup, nor can be controlled or recorded.41 EFFECT SEND/RETURNUse these sockets to connect an external Audio Effect generator device, to receive audio signal from the PMX20 channel (when the FX SEND button is enabled) and return its processed signal adjusted by the RETURN knob at the top panel. This procedure is not operated by VirtualDJ
