(21) 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 two line inputs.

(23) (24)

(25) (26)
Never connect devices with line level to the highly sensitive phono
(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).)
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.
(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

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 section 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 differences 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 infinite number of steps. When set to linear, the crossfader engages directly proportionally to the faders incremental movement. When set to logarithmic, the faders movement yields higher volume increases as the fader moves farther along its range of motion.

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 fine-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.
1.6 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. (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.

1.7 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. Thats 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 songs 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 difference in tempo from both channels is illustrated in the form of a nine-character message on the TEMPO DIFFERENCELED (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.

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)).
When no signal is present (or when the signal level is too low),
View the table (column Ajustable Parameter) to see which parameter
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.

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.).
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).

2.1 Rear panel connectors (40) (39) (38)
(38) These are the LINE i. e. CD inputs to connect a tape deck, CD or MD player etc. Unlike other channels, channel 1 features two line inputs. (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.

The DJX750 features an internal digital effects processor into which you can feed your master signal, the signals of the input channels or the mic signal. The module provides a number of standard effects, such as reverb, delay and echo, as well as various filter and modulation effects.
To select the signal to be processed, use the SOURCE selector (33). Turn the PROGRAM control (35) to select an effect. The corresponding
program number appears on the PROGRAM display (34). the selected preset.
Press and hold the PROGRAM control for about 2 seconds to load When the new effect has been loaded, turn the PROGRAM control (35)
to change the effects parameters. The parameter value is shown on the display.
(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).

Caution

(43) The externally processed signal is added to the MASTER output signal via the RETURN connectors. The effect signal volume may only be adjusted at the output control of the effects device itself. (44) The MASTER output is for connecting to an amplifier and can be adjusted with the MASTER fader (18).
