Be honest: who really likes to read manuals? We know you want to get started right away, but it is only after reading these instructions that you will fully understand and be able to properly use all the features your DX400 has to offer. Take the time to read everything through!
+This manual first describes the terminology used, so that you can fully understand the DX400 and its functions. Please read the manual carefully and keep it for future reference.
1.1 Before you begin
Your DJX400 was carefully packed in the factory and the packaging is designed to protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging and its contents for any signs of physical damage that may have occurred during transit.
+If the unit is damaged, please do NOT return it to BEHRINGER, but notify your dealer and the shipping company immediately. Otherwise claims for damage or replacement may not be granted.
To avoid overheating, ensure that there is enough space around the unit for cooling and that the device is not placed near other devices giving off heat.
+We would like to point out that high volume may damage your hearing and/or your headphones. Please turn the MASTER control all the way to the left before turning on the device. Always make sure that the appropriate volume is set.

2. CONTROL ELEMENTS
Fig. 2.1: PRO MIXER DJX400 control elements
2.1 Stereo channels 1 and 2
The TRIM control in the CHANNEL section is used to adjust the level of the input signal.
Each of the two input channels has a
+The total level also depends on the EQ setting. Thus, you should adjust the equalizer before regulating the level with the TRIM control.
Adjust the channel volume with the CHANNEL fader.
+Never connect devices with line level to the highly sensitive phono inputs! The output level of phono
You select the input signals with the INPUT SELECTOR switch (PHONO/CD). “Phono” is for connecting a turntable. “Line” must be selected for all other signal sources (e.g. CD or MD players). A special feature allows you to switch the input sensitivity of the phono input to
This is the AUTO BPM COUNTER DISPLAY(see Chapter 2.8).
The SYNC LOCK button is also a part of the AUTO BPM COUNTER (see Chapter 2.8).
2.2 Microphone channel
Select the volume of the microphone signal with the TRIM control in the MIC section.
There is a
2.3 MONITOR section
The MONITOR signal is your headphones signal, allowing you to listen to music without affecting the MASTER output signal.
The MONITOR Level control determines the volume of the headphones signal.
With the MONITOR SELECTOR button you select the signal to be routed to your headphones. You can choose from signals from channel 1, channel 2 or the MASTER signal. It is also possible to select two signal sources and listen to them simultaneously. That could either be the two input channels

happen, the MASTER signal is the only one that would be heard. The MASTER signal is taken post MASTER LEVEL control, whereas the signals from the two input channels are pre CHANNEL faders and are routed to the MONITOR section.
Table 2.1: Selecting a signal with the Monitor Select button
2.4 MASTER section
The LEVEL METER displays the signal level selected with
With this switch you determine whether it is the MASTER or the MONITOR signal to be indicated on the LEVEL METER. When the MONITOR LED lights up, it indicates the level of the headphones signal.
+In monitor mode, the LEVEL METER displays the channel 1 signal on the left and the channel 2 signal on the right.
This is the MASTER LEVEL control to adjust the output volume at the MASTER output (see).
The SURROUND control determines the intensity of the XPQ 3D surround effect (see Chapter 2.7).
2.5 CROSSFADER section
The CF CURVE switch, to the right of the CROSSFADER, allows you to put the fader control character in two stages. InSOFT mode the volume is controlled evenly over the whole slide. InSHARP mode the volume control is limited to the outer portions of the slide. Naturally, a difference in volume can occur when switching modes. Thus, don’t use this switch when the music is on!
The CROSSFADER is for crossfading between channels 1 and 2. The CROSSFADER, like the CHANNEL fader, is also a professional 45 mm fader.
The TIME OFFSET LED indicates the synchronisation of channels 1 and 2 (see Chapter 2.8).
The TEMPO DIFFERENCE LED displays tempo differences between the signals from channel 1 and 2 (see Chapter 2.8).
The BEAT ASSIST button is for manually determining the tempo for channels 1 and 2 (see Chapter 2.8).
2.6 Front panel connectors
Fig. 2.2: Headphones and microphone connector
The MIC IN connector is the balanced jack input for a dynamic microphone.
+We strongly discourage the use of cheap plugs for transmitting audio signals. Please use only
The PHONES OUT connector is for you to listen to bits of music with your headphones (MONITOR signal). Your headphones should have a minimum impedance of 32 ohms.
2.7 XPQ 3D surround effect
The XPQ 3D surround function is a
2.8 Auto BPM Counter
The PRO MIXER DJX400 auto BPM counter is an extremely useful feature. It ensures smooth transition from one track to the next, making your session an absolute success. It can calculate the various tempi of tracks in bpm (beats per minute). The channel 1 and channel 2 BPM counter sections are identical.
Each channel’s DISPLAY indicates the track tempo. 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 aSYNC LOCK buttonthat 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 theBEAT ASSIST button. 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 difference in tempo from channel 1 and channel 2 is illustrated in the form of a

To exit the SYNC LOCK or BEAT ASSIST modes, simply push the SYNC LOCK button once more on both channels.
Fig. 3.1: The DJX400 rear panel connectors
With the exception of the microphone and headphone connectors, the PRO MIXER DX400 only has cinch jacks, which can be found on the rear panel of the console.
The PHONO inputs for channels 1 and 2 are for connecting a turntable.
These are the CD inputs (Line) to connect a tape deck, CD or MD player etc.
The GND connectors ground the turntables.
With the PHONO/LINE switch it is possible to switch the input sensitivity of the PHONO inputs to
The DJX400 has an integrated effect path for an external effect device The MONITOR section signal is tapped via SEND and routed, for example, to an echo device. Thus, the signal at the SEND connector is identical to the headphones signal and is selected with the MONITOR SELECTOR button.
The externally processed signal is added to the MASTER output signal upon its RETURN. The effect signal volume may only be adjusted at the output control of the effect device itself, as the DJX400 has no additional level control for this purpose. If no effects are needed, the RETURN can also be used as an additional recording path for a sampler or the like. Here, too, the output volume must be adjusted on the external device.
+As soon as you are ready to add an effect signal to the output signal, the channel on your headphones (MONITOR) and the channel at the output (MASTER) must be the same. If you are listening to the other channel on your headphones, the effect signal of a completely different song will be added to the MASTER signal. This is because the effect device
gets its input signal from the MONITOR section (see ) and the effect signal produced in this way is
added to the MASTER signal.
The MASTER output is for connecting to an amplifier and is to be adjusted with the MASTER LEVEL control.
+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
DX400 before turning on the power amps. To be sure, slide all the faders to the bottom and switch all controls to the zero position.
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.

Fig. 3.2: DJX400 mains connection and serial number
Turn the DJX400 on with this switch.
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 amplifiers (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 DJX400: the sound is always clear and transparent.
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 115 V. N.B: should you desire to operate the unit outside Europe at 115 V, a higher fuse rating is required.
