PRO MIXER DX052
2. 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 input channel features a 2-band equalizer (HIGH
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 example, fading a frequency range out of a
music track.
+The verall level als depends n the EQ setting.
Thus, y u sh uld adjust the equalizer bef re
setting the input gain with the TRIM c ntr l.
The input channels come with a BAL(ANCE) control which
allows you to create the stereo image.
The CF REVERSE switch enables you to invert the direction
of the CROSSFADER (see ), so that you can quickly
switch from channel 1 to channel 2. This effect is created
by simply pushing the switch down (TAP)as soon as it
is released, it returns to its original position and your
2. CONTROL ELEMENTS

PRO MIXER DX052
3. CONNECTIONS
crossfade setting is as it was before. Pressed upwards,
the switch locks into the reversed position (HOLD). To
reset it, simply push it downwards.
You determine the input signals with the PHONO/LINE/LINE
switches. Phono is intended for connecting a turntable.
Line must be selected for all other signal sources (e. g.
CD or MD players). Thanks to switch on the rear, the
phono input can be switched to line level.
+Never c nnect devices with line level t the highly
sensitive ph n inputs! The utput level f ph n
pick-up systems is measured in milliv lts,
whereas CD players and tape decks have levels
measured in v lts, i.e. the level fr m line signals
is up t 100 times higher than that f the ph n
inputs.
The integrated 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 tempos of tracks in BPM (beats per minute).
The left display indicates the tempo on channel 1 and the
right display shows the tempo on channel 2.
+When n signal is present ( r when the signal level
is t l w), the BPM display sh ws nly dashes.
When the signal is present but can n t be identified,
the display sh ws 160 BPM and then sh ws the
said dashes. The beat c unter then attempts t get
an ther read ut. Theref re, 160 BPM is n usable
value; rather, it is simply an err r message when
the signal can n t be analyzed.
Adjust the channel volume using the CHANNEL fader.
The CURVE switch next to the channel fader enables you
to select between three fade modes: SOFT, MID and
SHARP. In SOFT mode the fader controls the volume in a
linear, continuous manner. Run a track through one of the
mixers channels and pull the fader down slowly: the
volume will decrease gradually. In SHARP mode the fader
takes on a more logarithmic effect, reducing the volume
faster towards the lower end of the fader range, even if
you move the fader smoothly. MID mode is a combination of
the SOFT and SHARP modes. Flipping the CURVE switch
may cause a sudden change in volume. We recommend
not changing this setting while a signal is present.
2.2 Microphone channel
Select the volume of the microphone signal with the LEVEL
control in the MIC section.
There is a 2-band equalizer (HI and LOW) in the
microphone section. This allows you to fine-tune your
voice to adapt perfectly to your sound.
The PAN(ORAMA) control determines the position of the
microphone signal within the stereo image of the MASTER
signal.
2.3 MASTER and M NIT R section
This is the MASTER level control to adjust the output
volume at the MASTER output (see ).
The XPQ SURROUND control determines the intensity of
the XPQ 3D surround effect (see chapter 2.5).
The CF CURVE control in the master section is similar to
the CURVE switches in channels 1 and 2 (see ). The
control allows you to fade between the various crossfader
curve modes.
The MONITOR signal is your headphones signal, allowing
you to listen to music without affecting the MASTER output
signal.
The MONITOR LEVEL fader determines the volume of
the headphones signal.
The MONITOR MIXING fader lets you fade between
channels 1 and 2 on your headphones.
The LEVEL METER displays the level of the signal selected
via .
With this switch you determine whether it is the MASTER
or the MONITOR signal (PFL) to be indicated on the LEVEL
METER. When the PFL LED lights up, it indicates the level
of the headphones signal.
+In m nit r m de, the channel 1 signal is displayed
n the left side f the LEVEL METER, and channel 2
n the right.
The CROSSFADER is for crossfading between channels
1 and 2. Like the channel faders, the crossfader section is
equipped with a professional 45-mm ULTRAGLIDE fader.
2.4 Front panel connectors
The MIC IN connector is the balanced jack input for your
dynamic microphone.
+We str ngly rec mmend the use f high-grade
cables and c nnect rs f r the transmissi n f audi
signals. Inferi r quality materials cann t supply
acceptable audi quality r c rr si n pr tecti n.
The PHONES OUT connector enables you to preview
tracks (MONITOR signal) on your headphones. Your
headphones should have a minimum impedance of
32 Ohms.
2.5 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. The XPQ SURROUND control
determines the intensity of the XPQ 3D surround effect.
3. CONNECTIONS
With the exception of the microphone and headphones
connectors, all of the DX052s audio connections are located on
the rear panel and supplied as RCA connectors.
Fig. 3.1: PRO MIXER DX052 rear panel onne tors
The PHONO inputs for channel 1 and 2 are for connecting
a turntable.
With the PHONO/LINE switch it is possible to switch the
input sensitivity of the PHONO inputs to line level. This
allows you to connect a tape deck or a CD player to the
PHONO inputs.

8
PRO MIXER DX052
These are the LINE inputs to connect a tape deck, CD or
MD player etc.
The GND connectors ground the turntables.
The DX052 features an integrated effects loop for the
connection of an external effects device/sampler. 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.
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.
Fig. 3.2: PRO MIXER DXD052 rear panel onne tors
The MASTER output is for connecting to an amplifier and
can be adjusted with the MASTER level control.
+Always turn the p wer amps n last t av id inrush
currents that can easily damage y ur speakers.
And, t av id sudden and unpleasant surprises
f r y ur ears, make sure there is n signal at the
DX052 bef re turning n the p wer amps. T be
sure, slide all the faders t the b tt m and switch
all c ntr ls t the zer p siti n.
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.
The POWER switch powers the DX052 on. You should
always make sure that the POWER switch is in the Off
position when initially connecting the unit to the mains.
+Please take n te: Merely switching the unit ff d es
n t mean that it is fully disc nnected fr m the
mains. When n t using the unit f r pr l nged
peri ds f time, please unplug the units p wer
c rd fr m the p wer utlet.
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.
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 DX052: the sound is always clear and
transparent.
+T disc nnect p wer fr m main, pull ut the main
c rd plug. When installing the pr duct, ensure that
the plug is easily accessible. If m unting in a rack,
ensure that the mains can be easily disc nnected
by a plug r by an all-p le disc nnect switch n r
near the rack.
