Lets be honest: nobody likes reading users manuals. e know you want to plug in and get jammin, but
please take the time to read the following instructions. eve kept them as short as possible, and it will be well
worth the few minutes it takes you. Armed with a thorough understanding of the VMX100s features and
functions, youll be able to get the most out of this exciting product.
+The following instructions will give you a brief run-down on the terminology and functions of
the VMX100. After reading, lease store this manual in a safe lace for future reference.
1.1 Before you get started
Your PRO MIXER was carefully packed in the factory and the packaging is designed to protect the unit against
rough handling. Nevertheless, we recommend that you carefully examine packaging and contents for any
signs of physical damage which may have occurred during transit.
+If the unit is damaged, lease do not return it to BEHRINGER, but notify your dealer and the
shi ing com any immediately. Otherwise, claims for damage or re lacement may not be
granted. Shi ing claims must be made by the consignee.
+If the unit needs to be shi ed, lease always use the original ackaging to avoid damage.
+Never let unsu ervised children lay with the VMX100 or with its ackaging.
+Please dis ose of all ackaging materials in an environmentally-friendly fashion.
Please take care to always ensure adequate ventilation. Do not place the PRO MIXER near heating units or
heat-generating devices in order to avoid overheating.
CAUTION!
+We would like to oint out that high volumes can ermanently damage your sense of hearing
and/or your head hone or s eaker systems. Therefore, lease turn the MAIN control in the
MIC/MAIN section all the way to the left before turning on the mixer. And lease exercise
caution and common sense when setting volume levels.

+Never connect line-level equi ment to the highly sensitive hono in uts! The out ut levels of
hono cartridge systems are in the millivolt range, whereas CD and MD layers, as well as
ta e decks, rovide out uts levels in the volt range. In other words, the level of line signals is
u to 100 times higher than hono out ut levels.
2
The GAIN control is used to adjust the input signal level.
+The overall level of your signal is also effected by the EQ settings. Its a good idea to adjust the
equalizer before you set the level with the GAIN control.
3
Each of the two input channels is equipped with a 2- AND EQUALIZER with kill characteristic. The
maximum amount of attenuation (-32 dB) is much higher than the maximum boost (+12 dB), allowing
entire frequency spectrums to be removed from a track.
4
The CHANNEL fader adjusts the final channel volume.
2.2 PFL section (Pre Fader Listening)
The PFL signal is a pre-fader headphones signal, enabling you to pre-listen to a signal source without effecting
the main signal.
5
The LEVEL control determines the volume of the headphones signal.
6
The MIX control lets you fade between channels 1 and 2.
7
The LEVEL METER displays the level of the signal selected via the MAIN/PFL button ( ).
8
The MAIN/PFL button allows you to route either the main or PFL signal to the display. Remember: PFL
is your pre-listening or headphone signal and MAIN is the signal assigned to the outputs of the VMX100.
+In PFL mode, the channel 1 signal is dis layed on the left side of the LEVEL METER, and
channel 2 on the right.
2.3 MIC/MAIN section
9
The MAIN knob controls the overall output volume.
10
The MIC LEVEL control adjusts the volume of the microphone signal.
2.4 Beat counter
The PRO MIXER VMX100s built-in beat counter is an extremely useful feature, allowing smooth crossfades
between two tracksan important key to the success of your performance. The beat counter analyzes and
displays the tempi of your tracks in BPM (Beats Per Minute). The beat counter sections of channel 1 and 2 are
identical.
The tempo of the track is shown in the respective channels DISPLAY ( ). In the case of multiple tempo
changes, the display would change continuously, causing unnecessary confusion and rendering the function
virtually useless. Enter the SYNC LOCK button ( ): with it, you can limit the range of possible tempo values
within a song. Pressing this button once the counter has caught and displayed a realistic value will simplify
things. The EAT ASSIST button ( ) allows you to set the beat counters tempo manually, similar to
tap tempo. Pressing the button three times in time with the track will set the beat counter and its display at
that tempo. The BEAT ASSIST and SYNC LOCK buttons are each equipped with an LED to show that the
respective function is activated.
Once the tempo of the two tracks have been determined and locked with the SYNC LOCK or BEAT ASSIST
buttons, the tempo difference between channel 1 and 2 will be depicted via the 9-segment TEMPO DIFFERENCE
LED display ( ). It shows the degree of the tempo difference by a respective deflection to the right (channel
2 track is faster) or to the left (channel 2 track is faster). The center LED lights when the tempi are equal. The
synchronization of channel 1 and 2 is shown in the TIME OFFSET LED display ( ) below the TEMPO

DIFFERENCE display. hen the center LED is lit, the tracks are in sync with each other. hen the display
moves to the left or right, the corresponding channel is running out of sync. The TEMPO DIFFERENCE and
TIME OFFSET displays are only active when the tempi of both channels have been locked as explained above.
To exit the SYNC LOCK or BEAT ASSIST mode, simply press the SYNC LOCK key in both channels again.
2.5 Crossfader section
16
The CROSSFADER is used to fade between channels 1 and 2.
17
The CURVE switch, located on the left side of the CROSSFADER, enables you to select between two
crossfade modes: SOFT and SHARP. In SOFT mode the crossfader fades between the channels in a
linear, continuous manner. This mode is recommended for slower, smoother crossfades. In SHARP
mode the crossfader takes on a more logarithmic effect, working faster towards the outer edges of the
fader range. Use this mode for faster, hard crossfades.
+Fli ing the CURVE switch may cause a sudden change in volume. We recommend not changing
this setting while a signal is resent.
18
The MIC INPUT connector is a balanced ¼" TRS socket for microphone connection.
+We strongly recommend the use of high-grade cables and connectors for the transmission of
audio signals. Inferior quality materials cannot su ly acce table audio quality or corrosion
rotection.
19
The HEADPHONES socket allows you to connect your headphones for pre-listening (PFL signal). For
best results, use headphones with an impedance rating of at least 32 Ohms.
3. REAR PANEL
ith the exception of MIC INPUT and HEADPHONES, all of the VMX100s audio connections are located on
the rear panel and supplied as RCA connectors.

+In order to avoid ower-u thum s, which can damage your louds eakers, lease ower u
your am lifier last. There should be no signal resent, e.g. no music laying, when you turn
on your am . In addition, we suggest that you set all volume-related controls to zero (down)
before owering u your system. Following these recautions will save you from un leasant
and otentially dangerous sur rises.
24
The TAPE output enables you to record your performance by connecting a tape deck, DAT recorder etc.
Unlike the AMP output, the TAPE level is fixed, so that you have to adjust the input level on the recorder.
25
The POWER ON switch turns on the PRO MIXER.
26
FUSE HOLDER/VOLTAGE SELECTOR. Before you connect the equipment to an AC outlet, please be
sure that the voltage displayed corresponds with your local AC voltage. If you should need to replace the
fuse, be sure to replace it with one of the same type and value. Some units allow you to switch between
240 V and 120 V by rotating the fuse holder.
+To o erate the unit at 120 V, you must install a fuse with the double am ere rating.
27
This is the socket for the power cable. The impulse behavior of any given amplifier circuit depends
largely upon the power supplys inherent reserves. All mixers contain numerous operational amplifiers
(op-amps) for processing line-level signals. Due to the restricted performance of their power supplies,
many mixers show stress symptoms when used under extreme conditions, resulting in inferior audio
quality. Thanks to its generously proportioned power supply, this will never happen to your VMX100: The
sound will always be clear, transparent and powerful.
