CROSSFADER: Blends audio between the channels assigned to the left and right side of the crossfader.
VOLUME: Volume Faders (mixer channel order is 3-1-2-4 decks). A different mixer channel order can be selected from VirtualDJ Settings
PFL: Press these buttons to send this channel's pre-fader signal to the Cue Channel for monitoring. When engaged, the button will be lit. By pressing one PFL button at a time, you will cue that channel alone (and deactivate PFL monitoring for the other channels). To cue to multiple channels simultaneously, press the PFL buttons for those channels at the same time.
CROSSFADER ASSIGN: Routes the audio playing on the corresponding channel to either side of the crossfader (A or B), or bypasses the crossfader and sends the audio directly to the Program Mix (center, OFF).
FILTER: Applies a resonance Filter on the software decks. Depending on the FILTER MODE (21) the Filter knob also offers 2 additional functions.
On FILTER ROLL mode, the knob applies a Loop Roll effect as well. The size of the loop roll starts from 1/2 beat and ends to 1/16 beat (left or right end position)
On FILTER FX Mode the knob also controls the 1st parameter of the selected effect. On zero position the effect slider gets value 0%, and at the right/left end positions the parameter gets value 100%.
EQ LOW: Adjusts the low (bass) frequencies of each mixer channel/deck. When Touch EQ Mode is activated, touching the knob will mute the corresponding channel's low frequencies (aka "EQ kill").*
EQ MID: Adjusts the middle (mid) frequencies of each mixer channel/deck. When Touch EQ Mode is activated, touching the knob will mute the corresponding channel's mid frequencies (aka "EQ kill").*
EQ TREBLE: Adjusts the high (treble) frequencies of each mixer channel/deck. When Touch EQ Mode is activated, touching the knob will mute the corresponding channel's high frequencies (aka "EQ kill").*
*Note: The used/killed frequencies depend on the selected EQ mode. Set the equalizerMode setting to Kill mode (from Conifg OPTIONS tab) if you wish to get a complete cut of sound when knobs are at 0% or touched on EQ Kill mode.
GAIN: Adjusts the audio level (gain) of the corresponding channel in the software or hardware Input. When Touch EQ Mode is activated, touching the knob will mute the sound of the corresponding mixer channel/deck (MUTE text will be visible on the Track’s Title/Artist on the GUI)
MASTER VU-METER: Shows the strength of the master output audio signal.
CH VU-METER: Shows the pre-fader strength of the channel's audio signal. When the WHITE led is lit, the corresponding channel limiter is engaged to prevent distortion of the audio signal.
PC/LINE: Switch decks 3 & 4 between hardware operation (analog audio sources connected on the back of the unit) and PC operation. When a channel is set to hardware mode, the corresponding software deck will be muted.
MASTER VOLUME: Adjusts the Master Output Volume (Hardware operation. Movement will not be visible on the VirtualDJ GUI)
BOOTH VOLUME: Adjusts the Booth Output Volume (Hardware operation. Movement will not be visible on the VirtualDJ GUI)
