1. Stereo Channels 1 to 4

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

Unlike other channels, channel 1 features two line inputs and the USB input.

(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 selec ted 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)).

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.

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

(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 +6 dB. This function can be very useful
when, for example, fading a frequency range out of a music track.

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

6 PRO MIXER DJX900USB User Manual

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 DJX900USB 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.

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.

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 CROSSFADER is used to fade between the channels you have selected

(see (21) ).

(23) The TIME OFFSET LED indicates the synchronization 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 DJX900USB: 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 a smooth blend to a steep cut in an innite number of
steps. When set to smooth blend (far left), one source fades in gradually
while the other fades out at the same rate. When set to steep cut (far right),
the sources quickly fade in and out at the far edges of the crossfader's range.
For example, with the CF CURVE knob set to the far right and the crossfader
set to the far left, only source A is audible. As the crossfader moves to the
right, source B quickly fades to full volume. Both sources remain at full
volume for most of the middle range until source A quickly fades out just
before the crossfader reaches its far right position.

(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 determine 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.

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)).

6. XPQ 3D Surround Eect

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).

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 respec tive 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.

7 PRO MIXER DJX900USB User Manual

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 the 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 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 xed in one of
the waysdescribed.

◊ 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.

The DJX900USB features an internal digital eects 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 eects, such as reverb, delay and
echo, as well as various lter and modulation eects.

• To select the signal to be processed, use the SOURCE selector (33).

• Turn the PROGRAM control (35) to select an eect. The corresponding

program number appears on the PROGRAM display (34) .

• Press and hold the PROGRAM control for about 2 seconds to load the

selectedpreset.

• When the new eect has been loaded, turn the PROGRAM control (35)

to change the eect’s parameters. The parameter value is shown on
thedisplay.

◊ 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.”).

• Use the LEVEL control (36) to determine the volume level of the eect signal.

• Activate the eect signal by pressing the FX ON switch (37) .

Press the PROGRAM control one more time to use it for selecting eects again.

9. Connections

9.1 Rear panel connectors

(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 � 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.

(42) The DJX900USB 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).

(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 DJX900USB
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 output
volume is xed, making it necessary for you to adjust the input level on the
recording device.

(47) The POWER switch powers the DJX900USB 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.

(51)(40)

(50)(41)(48)

(51) The DJX900USB has built-in USB connectivity, allowing stereo signals to be

sent to and from the mixer and a computer. The audio sent from the mixer to
a computer is identical to the TAPE signal. Audio being sent from a computer
to the mixer can be selected with the Channel 1 LINE/CD/USB switch.

◊ Connect a USB type B plug into the USB jack on the mixer, and the

other end into a free USB port on your computer. There are no required
drivers, but we recommend that PC users install the included ASIO
driver. The driver can also be downloaded from behringer.com.

10. Initial Operation

◊ Ensure adequate air supply and to avoid overheating do not place the

unit near radiators etc.

◊ Before you connect your unit to the mains, please make sure that your

local voltage matches the voltage required by the unit. The fuse holder
on the mains connec tor has 3 triangular markings, with two of these
triangles opposing each other. The unit is set to the operating voltage
printed next to these markers and can be set to another voltage by
turning the fuse holder by 180°.

 Caution

(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 DJX900USB: 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.

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

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 of f 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.
