1.1 Stereo channels 1 to 4

(1) Use the LINE/CD switch to select the input signal for channel 1. Unlike other

channels, channel 1 features t wo 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 exibility (see (41)).

(34)

(35)

(36)

(19)

(37)

(20)(26)(25)(24)(23)(22)(21)

◊ 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.

(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.

5 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.

◊ The overall level also depends on the EQ setting. Thus, should adjust

the equalizer before setting the input gain with the GAIN control.

(5) The 10-digit LED chains display the signal level of the input signals.

(6) Adjust the channel volume using the CHANNEL fader.

1.2 Microphone channel

(7) The MIC IN connector is the balanced XLR input for your dynamic microphone.

(8) Set the volume of the microphone signal with the GAIN control in the

MICsection.

(9) There is a 3-band equalizer (HI, MID and LOW, no kill characteristic) inthe

microphone section. This allows you to ne-tune your voice to adapt
perfectly to your sound.

(10) Activate the microphone channel using the MIC ON switch. The channel is

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.

1.5 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).

(22) The VCA controlled CROSSFADER is used to fade between the channels you

have selected (see (21) ). Like the channel faders, the crossfader sec tion is
equipped with a professional 45-mm fader.

(23) The TIME OFFSET LED indicates the synchronisation of tracks

(see chapter 2.7).

(24) The TEMPO DIFFERENCE LED displays tempo dierences between the tracks

(see chapter 2.7).

(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.

(26) The CF CURVE control lets you alter the control characteristic of the

crossfader between linear and logarithmic in an innite 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.

1.6 XPQ 3D surround eect

1.3 Monitor section

The MONITOR signal is your headphones signal, allowing you to listen to music
without aecting 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.

(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.

(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.

(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)).

The XPQ 3D surround func tion is a built-in eect that puts the nishing 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 eect by using the SURROUND control (27), while the XPQ ON
switch (28) turns the XPQ eect on (the respective LED is lit).

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.

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.

When you have limited the tempo of the tracks on both channels with the SYNC
LOCK or BEAT ASSIST buttons, the dierence in tempo from both channels is
illustrated in the form of a nine-character message on the TEMPO DIFFERENCE­LED (24). The extent of theT dierence 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 lef t 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 xed in one of
the waysdescribed.

6 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.

To exit the SYNC LOCK or BEAT ASSIST modes, simply push the SYNC LOCK button
once more on both channels.

(39) The PHONO inputs for channels 2 to 4 are for connecting a turntable.

(40) The GND connectors ground the turntables.

(41) With the PHONO/LINE switch it is possible to switch the input sensitivity of

the PHONO inputs 2 to 4 to line level. This allows you to connect a tape deck
or a CD player to the PHONO inputs.

7 PRO MIXER DJX750 User Manual

(42) The DJX750 features an integrated eects loop for the connection of an

external eects 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).

 Caution

Please note that when operating the unit at 120 V, a higher fuse rating is
required. Please refer to the “Specications” for details.

(43) The externally processed signal is added to the MASTER output signal via the

RETURN connectors. The eect signal volume may only be adjusted at the
output control of the eects device itself.

(44) The MASTER output is for connecting to an amplier 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.

(45) The BOOTH output gives you an additional option of connecting an amplier

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.

(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 outp ut volume is
xed, 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 “O ” position when initially connecting the unit
to the mains.

◊ Merely switching the unit off does not mean that it is fully disconnected

from the mains. When not using the unit for prolonged periods of time,
please unplug the unit’s power cord from the power outlet.

(48) This is the connector for the power cable. This is where the advantage of a

sophisticated internal power supply can be seen: the pulse behaviour of each
amplifying circuit is mainly determined by the voltage reserves available.
Each mixing console is equipped with numerous operational ampliers
(opamps) to process line level signals. Due to limited output of their power
supplies, many mixing consoles show signs of “stress” when subjected to
heavy loads. But not your DJX750: the sound is always clear and transparent.

(49) FUSE HOLDER / VOLTAGE SETTING. Before connecting the unit to the mains,

ensure that the voltage setting matches your local voltage. Blown fuses
should only be replaced by a fuse of the same type and rating. On some
units, the fuses holder can be switched to one of two positions, i.e. 230 V and
120 V. Please note: should you desire to operate the unit outside Europe at
120 V, a higher fuse rating is required.

◊ To disconnect power from main, pull out the main cord plug.

When installing the product, ensure that the plug is easily accessible.
If mounting in a rack, ensure that the mains can be easily disconnected
by a plug or by an all-pole disconnect switch on or near the rack.

(50) SERIAL NUMBER.

If you set the unit to a dierent mains voltage, be sure to use a fuse of the correct
type and rating. Please refer to the “Specications” 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.

The mains connection is made using the enclosed power cord and a standard IEC
receptacle. It meets all international safety certication 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.

◊ 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.
