VirtualDJ 8 User Manual


Interface - Mixer

Audio Mixer



The MIXER panel offers a 2 or 4 channel Audio Mixer with HIGH, MID and LOW Equalizer knobs, GAIN knobs, FILTER knobs to control the resonance Filter effect along with Volume Faders, Audio Crossfader and PFL selection buttons.




  1. Gain - Use the GAIN knob to adjust the Gain applied to the loaded track. If the knob is to the middle position (12 o’clock) the output level is set by the software to zero dB in order to normalize the audio levels (0 dB by default or other value defined from Options).

    The applied gain value will be displayed on the deck’s Info area. Double-click to set the GAIN to the middle position (zero dB value) When a track is loaded on a deck, VirtualDJ will calculate and set the output level of the track to the given zero dB value. The GAIN knob can be used then to make additional adjustments. VirtualDJ will set the gain to zero (or saved value) if the track is pre-analyzed or has been played before. If not, the software will set the gain to its zero value (if the track is not playing by the time the track is fully loaded). Different behaviors are available by changing the AutoGain setting (see Options).

    More information on VirtualDJ’s gain structure can be found here.

  2. EQ - Use the HIGH, MID and LOW knobs to adjust the high, mid and low equalizer bands of each of the available mixer channels. Double-click to reset each one of the EQ bands to zero (off) position. Right-click to Kill* any of the EQ bands. The central frequency values of each of the 3 EQ bands can be adjusted from the Options.

    - By default the EQ knobs do not completely cut off (kill) the frequencies. Kill mode can be selected from Options.

    - By default the EQ applies on the Master Output. EQ can also affect the PFL (prelisten) channel if the setting is changed (see Options).

  3. Volume - Used to control the volume of each one of the available mixer’s channels. If an External Mixer configuration is used (See Audio Setup), it is best to leave the volume faders in their maximum (top) position.

  4. Filter - Use the FILTER knobs to apply a Low-Pass or a High-Pass filter to each of the available mixer channels. On the middle position, no Filter is applied. Double-click to reset (off position).
    (The resonance of the Low-High Pass filter can be adjusted using a custom slider and filter_resonance VirtualDJ script action.)

  5. PFL - Use the PFL (Pre-Fade Listen) buttons to send any of the mixer channels to the Prelisten (Headphones) channel.

  6. VU meter - The VU meters can display either the Output level of the deck routed to the mixer or the
    Output level of the mixer’s channel (after Volume adjustments). Right clicking the VU meter will provide the option in the 2 channel mixer. In the 4 channel mixer, the option becomes available by clicking on Mixer Options.

  7. Crossfader - Slide the crossfader to route the left or right deck to the Master Output. If the crossfader is at the far left side, only the left deck will be audible in the Master Output. If the crossfader is at the far right side, only the right deck will be audible in the Master Output. At any other position, both decks will be audible. For External Mixer setups the crossfader should remain in the middle

  8. Crossfader Assignment - Use the crossfader assign buttons to assign a deck as left or right side of the crossfader. If the crossfader is at the far left side, only the left-assigned decks will be audible in the
    Master Output. If the crossfader is at the far right side, only the right-assigned decks will be audible in the Master Output. At any other position, all right- or left-assigned decks will be audible. If a deck is not assigned as left or right, it will be audible regardless of the crossfader position

  9. Headphone Control - Adjustment for headphone (PFL) volume and Mix Adjustment. The Mix Adjustment allows you to adjust between the PFL and Master Outputs in the headphones. Turning the dial to the left will only allow the PFL to be audible while turning it to the far right will only make the Master Output audible. Leaving it in the center (12 o’clock) position will be an even mix of PFL and Master Outputs.

    Note: If no headphones channel is enabled (default) in the Audio Setup, the headphone adjustment dials will remain empty (no fader lines).

  10. Mixer Options (4 Deck) - Mixer Options has multiple adjustments that can be made to customize how the mixer behaves:



    Mixer Order
    There are 3 available channel layouts; 3-1-2-4 (default), 1-3-4-2, and 1-2-3-4. This selection is saved across sessions.

    Level Indicators
    Displays the VU meters or the Level meters for each mixer channel.

    Crossfader Curve
    6 individual settings are available as to how the crossfader mixes the different channels; Full, Smooth (default), Cut, Scratch, Disabled or Hamster (reversed).

    Fake Mixer
    This an indicator (not a selection) for midi controllers that use this feature. If this mode is selected by the hardware unit, the mixer of the unit will not control the internal software mixer, but the displays will follow its movements. This option will only appear if a Midi controller with a fake mixer is connected.
