1.1 Stereo channels 1 to 4  
(1) Use the LINE/CD switch to select the input signal for channel 1. Unlike other  
Never connect devices with line level to the highly sensitive phono  
inputs! The output level of phono pick-up systems is measured in  
millivolts, whereas CD players and tape decks have levels measured in  
volts, i.e. the level from line signals is up to 100 times higher than that  
of the phono inputs.  
channels, channel 1 features two line inputs.  
(2) You determine the input signals for the channels 2 to 4 with the PHONO/CD  
i.e. PHONO/LINE switch (channels 3 and 4). “Phono” is intended for  
connecting a turntable. “Line” i. e. “CD” must be selected for all other signal  
sources (e. g. CD or MD players). The input sensitivity of the phono input can  
be switched to line level, allowing utmost flexibility (see (41)).  
(3) The GAIN control in the CHANNEL section is used to adjust the level of the  
input signal. The level meter (5) reads the input level.

PRO MIXER DJX750 User Manual  
(4) Each of the input channels features a 3-band equalizer (HI, MID and LOW)  
with kill characteristic. Thus, the signal can be attenuated to a much greater  
extent (-32 dB) than it can be raised (+12 dB). This function can be very  
useful when, for exmple, fading a frequency range out of a music track.  
1.5 Crossfader section  
(21) ASSIGN A and ASSIGN B selectors let you determine which input signals are  
routed to CROSSFADER sides A and B. You can also alternate between these  
two signals by using the CROSSFADER (see below).  
The overall level also depends on the EQ setting. Thus, should adjust  
the equalizer before setting the input gain with the GAIN control.  
(22) The VCA controlled CROSSFADER is used to fade between the channels you  
have selected (see (21)). Like the channel faders, the crossfader section is  
equipped with a professional 45-mm fader.  
(5) The 10-digit LED chains display the signal level of the input signals.  
(6) Adjust the channel volume using the CHANNEL fader.  
(23) The TIME OFFSET LED indicates the synchronisation of tracks  
(see chapter 2.7).  
1.2 Microphone channel  
(24) The TEMPO DIFFERENCE LED displays tempo differences between the tracks  
(7) The MIC IN connector is the balanced XLR input for your dynamic microphone.  
(see chapter 2.7).  
(8) Set the volume of the microphone signal with the GAIN control in the  
(25) A 3-band kill switch is available for use with both the left and the right side  
of the crossfader (KILL A and KILL B respectively). Kill switches are used to  
lower three separate frequency ranges (LOW, MID and HIGH) up to -32 dB.  
When using the kill switch, the equalizer of ordinary DJ mixers usually  
loses its functionality. Not the case with the DJX750: the EQs can be used to  
achieve an even more pronounced lowering of a particular frequency range.  
MIC section.  
(9) There is a 3-band equalizer (HI, MID and LOW, no kill characteristic) in the  
microphone section. This allows you to fine-tune your voice to adapt  
perfectly to your sound.  
(10) Activate the microphone channel using the MIC ON switch. The channel is  
(26) The CF CURVE control lets you alter the control characteristic of the  
crossfader between linear and logarithmic in an infinite number of steps.  
When set to linear, the crossfader engages directly proportionally to  
the fader’s incremental movement. When set to logarithmic, the fader’s  
movement yields higher volume increases as the fader moves farther along  
its range of motion.  
active when the corresponding LED is lit.  
(11) The DJX750 is equipped with a talkover function, which works very simply:  
if you speak into the microphone while a track is running, the volume of  
the music is automatically reduced, so that your voice is always “in front”.  
The TALK control allows you to determine how much the music volume is  
lowered (max. -24 dB). This function can come in handy when your own voice  
needs to be prominently heard, as in when making an announcement etc.  
1.6 XPQ 3D surround effect  
The XPQ 3D surround function is a built-in effect that puts the finishing touch  
to your music and turns every gig into a real experience. The widening of the  
stereo base makes for a livelier, more transparent sound. You can determine the  
intensity of the effect by using the SURROUND control (27), while the XPQ ON  
switch (28) turns the XPQ effect on (the respective LED is lit).  
1.3 Monitor section  
The MONITOR signal is your headphones signal, allowing you to listen to music  
without affecting the MASTER output signal.  
(12) When the MODE switch is in the “Split” position, channel PFL is located on the  
left side of the headphones, while the MASTER signal is on the right side. In this  
case, the MIX control (see below) serves no function. While in “Stereo” mode,  
you can use the MIX control to alternate between MASTER signal and PFL.  
1.7 Auto BPM counter  
The integrated auto BPM counter is an extremely useful feature. It ensures  
smooth transition from one track to the next, taking a lot of the guesswork out.  
It can calculate the various tempos of tracks in bpm (beats per minute). Both BPM  
counter sections are identical and both show the BPM value of the two signals  
routed to the crossfader. The LEDs located above the DISPLAYs 1 - 4 (29) indicate  
which of the four input channels are routed to the respective BPM counter.  
(13) When in “Stereo” mode, the MIX control lets you determine which signal can  
be heard via the headphones. When the control is turned to its left-most  
position (CUE), you hear the PFL signal only; when the control is turned to its  
right-most position, you hear the MASTER signal only. Alternating the MIX  
control between the two end positions lets you dermine the relative ratio  
between the two signals in your headphones.  
The tempo of the track assigned by using the ASSIGN A or ASSIGN B keys is shown  
in the respective Display (30). Several tempo changes in one track would produce  
a constant display of various BPM values and thus lead to unnecessary confusion.  
That’s why the beat counter sections each have a SYNC LOCK button (31) that can  
be used during the song to limit the range of possible tempo values. This makes  
sense if the counter has already calculated a realistic value. You can do the  
same thing manually with the BEAT ASSIST button (32). Pushing this button at  
least three times in sync with the song’s tempo results in the calculated tempo  
appearing in the DISPLAY. The Beat Assist and SYNC LOCK buttons are each  
equipped with a LED.  
(14) The Level control determines the volume of the headphones signal.  
(15) Connect your headphones using the PHONES OUT stereo connector.  
Your headphones should have a minimum impedance of 32 Ohms.  
(16) To select the PFL signal for the headphones, use the MONITOR CUE keys  
(CH-1 to CH-4, MASTER, FX). You can also select multiple signal sources and  
listen to them simultaneously. LEDs on corresponding keys are lit when a  
channel is routed to the headphones.  
1.4 Master section  
(17) The LEVEL METER displays the level of the MASTER signal.  
When you have limited the tempo of the tracks on both channels with the SYNC  
LOCK or BEAT ASSIST buttons, the difference in tempo from both channels is  
illustrated in the form of a nine-character message on the TEMPO DIFFERENCE-  
LED (24). The extent of theT difference in tempo is indicated by a corresponding  
swing to the right (signal A is slower) or to the left (signal B is slower). When the  
middle LED lights up, the tempi are the same. The TIME OFFSET LED (23) below  
that displays the signal A and B synchronisation. Should the middle LED light  
up, the tracks are synchronised. Should the display move to the left or right,  
the channels are not synchronised. The TEMPO DIFFERENCE and TIME OFFSET  
displays are only active if the tempi of both channels have been fixed in one of  
the ways described.  
(18) The MASTER fader allows you to adjust the output volume at the MASTER  
output (see (44)).  
(19) The MASTER BALANCE control for the MASTER output is for setting the  
stereo image.  
(20) The BOOTH LEVEL control adjusts the output level of the BOOTH output  
(see (45)).

PRO MIXER DJX750 User Manual  
When no signal is present (or when the signal level is too low), the BPM  
display shows only dashes. When the signal is present but can not be  
identified, the display shows 160 BPM and then shows the said dashes.  
The beat counter then attempts to get another readout. Therefore,  
“160” BPM is no usable value; rather, it is simply an error message  
when the signal can not be analyzed.  
View the table (column “Ajustable Parameter”) to see which parameter  
of the selected effect can be modified.  
The parameter values of the delay and echo effects are displayed in  
BPM (beats per minute). The selectable range is from 80 to 160 BPM.  
The display only shows two digits and so values of 100 and above are  
represented with a dot behind the number (for example, 120 BPM is  
displayed as “20.”).  
To exit the SYNC LOCK or BEAT ASSIST modes, simply push the SYNC LOCK button  
once more on both channels.  
Use the LEVEL control (36) to determine the volume level of the effect signal.  
Activate the effect signal by pressing the FX ON switch (37).

(42) The DJX750 features an integrated effects loop for the connection of an  
external effects device. The MONITOR signal is taken at the SEND output  
and routed, for example, to a reverb processor. Thus, the signal at the SEND  
connector is identical to the headphones signal and is selected with the  
MONITOR CUE buttons (16).

type and rating. Please refer to the “Specifications” for details.  
Blown fuses must be replaced by fuses of the correct rating!  
Please refer to the “Specifications” section for the applicable rating.  
Before you change the fuse, switch off the device and pull the plug to  
avoid electric shock or damage to the device.  
(44) The MASTER output is for connecting to an amplifier and can be adjusted  
with the MASTER fader (18).  
Always turn the power amps on last to avoid inrush currents that can  
easily damage your speakers. And, to avoid sudden and unpleasant  
surprises for your ears, make sure there is no signal at the DJX750  
before turning on the power amps. To be sure, slide all the faders to the  
bottom and switch all controls to the zero position.  
The mains connection is made using the enclosed power cord and a standard IEC  
receptacle. It meets all international safety certification requirements.  
Please make sure that all devices are properly grounded. For your own  
safety, never remove or disable the ground conductors from the devices  
or on the power cords. The unit must always be connected to the mains  
outlet with a protective grounding connection.  
(45) The BOOTH output gives you an additional option of connecting an amplifier  
in order to, for example, feed the signal into your monitors or to bring sound  
to an extra area. The BOOTH output level is regulated by using the BOOTH  
LEVEL control (20) of the MASTER section.  
The sound quality may diminish within the range of powerful  
broadcasting stations and high-frequency sources. Increase the  
distance between the transmitter and the device and use shielded  
cables for all connections.  
(46) Using the TAPE output you can record your music by connecting devices such as  
tape decks, DAT recorders etc. Unlike the MASTER output, the output volume is  
fixed, making it necessary for you to adjust the input level on the recording device.  
(47) The POWER switch powers the DJX750 on. You should always make sure that  
the POWER switch is in the “Off” position when initially connecting the unit  
to the mains.
