7. Channel Cue: Press these buttons to send each channel's pre-fader signal to the headphones'
cue channel. Press more than one of these buttons at the same time to send their channels'
signals to the cue channel simultaneously.
8. Filter Knob: Turn these knobs to adjust the filter applied to each channel. Turn the knob
counter-clockwise to apply a low-pass filter. Turn the knob clockwise to apply a high-pass filter.
9. Filter Button: Press this button to enable or disable the filters (controlled by the Filter knobs) on
all channels.
10. Sweep FX Knob: Turn these knobs to adjust the balance between the "wet" signal (the sweep
effect's output signal) and "dry" signal (audio without sweep effects applied). Select the center
(12:00) position to select an entirely dry signal.
11. Sweep FX Buttons: Press one of these buttons to enable or disable an effect that you can
control with the Sweep FX knobs. Only one of these buttons can be enabled at a time.
•
Dub Echo: This effect is a brief echo. Starting from the center (12:00) position, turn a
Sweep FX knob counter-clockwise to decrease the length of the delay and increase the
feedback, or turn it clockwise to increase the length of the delay as well as the feedback.
•
Noise: This effect adds noise to the signal. Starting from the center (12:00) position, turn a
Sweep FX knob counter-clockwise to add white noise with a time-based gate effect
synchronized with the channel's tempo, or turn it clockwise to add white noise.
•
Wash Out: This creates a transition effect. Turn a Sweep FX knob to its most counter-
clockwise (minimum) position to apply a 1/2-beat echo that will also mute the channel's
normal audio signal, or turn it to its most clockwise (maximum) position to apply a 1-beat
echo.
•
Gate: This effect applies a time-based gate effect to the signal. Starting from the center
(12:00) position, turn a Sweep FX knob counter-clockwise to apply a gate effect
synchronized with the channel's tempo, or turn it clockwise to apply a gate effect that
attenuates the signal. The farther clockwise the knob is turned, the greater the attenuation.
12. BPM FX Indicators: These lights will illuminate to indicate if a channel is selected and being
affected by the BPM effect module when the FX Channel Assign knob is set to Channel 1, 2, 3,
or 4; X-Fader A or B (if the channel is assigned to the active side); or Master (all channels).
13. Crossfader Assign: Routes the audio playing on the corresponding channel to either side of the
crossfader—A (left) or B (right)—or bypasses the crossfader and sends the audio directly to the
program mix—Thru (center).
14. Crossfader: Use this crossfader to mix between the active decks.
15. Crossfader Indicators: These lights will illuminate to indicate if a side of the crossfader is
selected and being affected by effects module (when the FX Channel Assign knob is set to X-
Fader A or B).
16. X Fader Contour: Turn this knob to adjust the slope of the crossfader. Turn the knob to the left
for a smooth fade (mixing) or to the right for a sharp cut (scratching). The center position is a
typical setting for club performances.
17. Ch Fader Contour: Turn this knob to adjust the volume slope of the channel faders. Turn the
knob counter-clockwise to have the volume get louder "later" (closer to the top of the fader).
Turn it clockwise to have the volume get louder "earlier" (almost immediately after moving the
fader from its minimum position). The center position is a linear volume increase.
18. X Fader Start: Use this switch to enable or disable crossfader start. When enabled, you can
automatically start playback on compatible Denon DJ media players assigned to each side of the
crossfader by moving the crossfader toward that side.
19. Channel Fader Start: Use this switch to enable or disable channel fader start. When enabled,
you can automatically start playback on compatible Denon DJ media players connected to each
channel by moving the channel fader upward.
20. Booth: Turn this knob to adjust the volume level of the booth outputs.
21. Master Level Meters: These LEDs display the audio signal level of the master mix (sent out of
the master outputs).
22. Master: Turn this knob to adjust the volume level of the master outputs.
