							gling the shift button, this will be indicated by a blinking shift LED. A hard shift is performed by holding 
down the shift button and combining it with another button.
NOTE: When performing a hard shift, it’s recommended you release the secondary button 
before releasing the Shift button, this is to prevent MIDI latches unless the MIDI function is a 
temporary function. 
10. MASTER VOLUME LEVEL INDICATORS - The  dual  MASTER  LEVEL  LED  indicators  are  used 
to detail the master fader output level. The meters will detail the output level of both the left and right 
channels.
11.  FEATHER FADER PLUS CROSSFADER - This fader is used to blend the output signals of chan-
nels one and two together. When the fader is in the full left position (channel 1), the output signal of 
channel one will be controlled by the master volume level. The same fundamentals will apply for chan-
nel  two.  Sliding  the  fader  from  one  position  to  another  will  vary  the  output  signals  of  channels  one 
and two respectively. When the crossfader is set in the center position, the output signals of both the 
channels one and channels two will be even.
12. CUE, SYNC, PITCH BEND, & PLAY/PAUSE -
    CUE 1 & 2 - These buttons will set or trigger hot cue 1 or 2.
    DELETING HOT CUE POINTS - If a hot cue point is set, it is indicated by a lit Cue button LED. If    
    you wish to delete a hot cue point, press the Shift button. The shift button LED will flash along with    
    the Cue LEDs. Press the Cue button that contains the hot cue you wish to delete. After, 
    press the Shift button  again to disable the soft shift.
    SAMPLER (MIDI) - Virtual DJ has a built in Sampler. To use the sampler you must activate the        
 
    Sampler control. Pressing the Shift button and Up button will give you access to samples 1-4. 
    The samples can be triggered by pressing Cue 1 and Cue 2 on the right side of the mixer. The left     
    side being samples 1 & 2 and the right side being samples 3 & 4.

source  connected  to  these  jacks.  Turntables  equipped  with  MM  pickup  cartridge  (All  DJ  turntable 
use MM pick-up cartridges) may be connected to these jacks as long as the CHANNEL LINE LEVEL 
SELECTOR SWITCH (16) is in the “PHONO” position. When CD players, Tape Decks and other line 
level instruments are connected to these jacks the CHANNEL LINE LEVEL SELECTOR SWITCH (16) 
is in the “LINE” position. Never connect line level instruments (CD players, tape decks, etc.) to these 
jacks when the CHANNEL LINE LEVEL SELECTOR SWITCH (16) is in the “PHONO” position, THIS 
MAY SERIOUSLY DAMAGE YOUR MIXER! The  red  colored  RCA  jack  represents  the  right  channel 
input and the white represents the left channel input. The channel SOURCE SELECTOR SWITCH (3) 
must be in the “Analog” position, to monitor any source connected to these jacks.
16.  CHANNEL  LINE LEVEL SELECTOR SWITCHES - These switches are used to change the volt-
age line levels of there respected  Phono / Line RCA inputs jacks. When connecting turntables with 
magnetic  cartridges  to  these  jacks  be  sure  the  corresponding  switch  is  in  the  “PHONO”  position, 
and when using line level input devices be sure this switch is in the “LINE” position. Always be sure

18. RCA MASTER OUTPUTS - The  Master  Output  includes  a  pair XLR BALANCED JACKS (20) 
as well as a pair of RCA Unbalanced Jacks. The RCA jacks send a low current unbalanced output 
signal.  These  jacks  should  only  be  used  for  shorter  cable  runs  to  signal  processors  or  looping  to 
another mixer. For cable runs greater than 15 feet use the XLR BALANCED JACKS (20).
19. BOOTH BALANCED XLR OUTPUT JACKS - The  Booth  Output  3-pin  XLR  jacks  send  a  high 
current  balanced  output  signal.  These  jacks  should  be  used  when  you  will  be  driving  an  amp  or 
other audio equipment with a balanced input, or whenever you will be running a signal line greater 
than 15 feet. Always, use these jacks whenever possible. 
20. BALANCED XLR MASTER OUTPUT JACKS - The  Master  Output  includes  a  pair  of  XLR 
Balanced  jacks  as  well  as  a  pair  of RCA UNBALANCED JACKS (18).  The  3-pin  XLR  jacks  send  a 
high current balanced output signal. These jacks should be used when you will be driving an amp or 
other audio equipment with a balanced input, or whenever you will be running a signal line greater 
than 15 feet. Always, use these jacks whenever possible. 
22.  AC CONNECTION - This connector is used to supply main power to the unit via the included 
detachable power cord. The power connection uses an I.E.C. type connector, use only the supplied, 
polarized AC power cord. Use only a power cord that matches this type of connection. Be sure to 
only connect this unit to a power outlet that matches the printed power label on the unit. Never use 
a power cord when the ground prong has been removed or broken off. The ground prong is used to 
reduce the risk of electrical shock in case of an electrical short. This cord is designed to fit in one 
direction  only.  Do  not  attempt  to  force  a  cord  if  it  does  not  fit,  be  sure  the  cord  is  being  inserted 
properly.
23.  MAIN POWER SWITCH - This is the main power ON/OFF button. Before main power is applied, 
be  sure  you  have  made  all  connections  to  the  mixer.  Also  be  sure  your  amplifier(s)  is(are)  tuned  off. 
Remember to avoid damaging pops to the speakers, the mixer is turned on first and turned off last.

24.  HEADPHONE JACK - This jack is used to connect your headphones to the mixer allowing you to 
monitor the cue source. Use headphones only rated at 8 ohms to 32 ohms. Most DJ headphones are 
rated at 16 ohm, these are highly recommended. Always be sure the CUE LEVEL VOLUME (6) is set to 
minimum before you put the headphones on.
25.  REVERSE FUNCTION SWITCH - Both the crossfader and the channel faders will reverse func-
tion  when  the  reverse  switch  is  activated.  When  reversing  the  crossfader,  channel  two  of  the  cross-
fader will control volume output for fader channel one and channel one of the crossfader will control 
volume  output  for  channel  fader  two.  When  reversing  the  channel  faders,  moving  the  fader  in  an 
upwards  direction  will  decrease  channel  volume  and  moving  the  fader  in  a  downwards  direction  will 
increase channel volume.
26.  CROSSFADER CURVE ADJUSTMENT - This rotary knob is used to change the way the cross-
fader will operate. The crossfader can operate in different modes, “NORMAL CURVE”, “QUICK CURVE” 
or any variation of the two. (Quick Curve usually used for scratching).

Due to fog residue, smoke, and dust, cleaning the mixer should be carried out periodically to residue 
build up.  
1.   Use normal glass cleaner and a soft cloth to wipe down the outside casing.
2.    Use a cleaner specially designed for electronics to spray in and around the knobs and switch.     
This will reduce small particle built up that can effect the proper operation of the mixer. 
3.   Cleaning should be carried out every 30-60 days to prevent heavy built up.
4.  Always be sure to dry all parts completely before plugging the mixer in.
Cleaning frequency depends on the environment in which the mixer operates (i.e. smoke, fog residue, 
dust, dew).
The crossfader is “Hot Swapable” which means it may be replaced at any time, even when power is 
applied. Only replace with American Audio Part Feather Fader Plus. Replacing with any other model 
fader may seriously damage your mixer.
Replacing the Crossfader:
1.   Disconnect the mixers main power supply
2.  Using a number two Phillips screw driver, unscrew the each of the stainless steel retain screws    
that hold the crossfader in place.
3.  Gently remove the crossfader from its seated position. You may need to wiggle the crossfader    
slightly to remove it.
4.  After removing the crossfader, disconnect the ribbon cable that attaches the crossfader to the    
PC board. Grasp the crossfader by its base and pull the ribbon cable by its connector not the   
actual cables. The connector is designed to only fit one way, so don’t worry about the connec  
tors orientation.
5.  Connect the new crossfader to the ribbon cable and replace in reverse order.
