2. CONTROL ELEMENTS
2. CONTROL ELEMENTS
2.1 Microphone channels
These are the balanced XLR connectors for dynamic
microphones.
Using the 3-band microphone equalizer (HIGH, MID and
LOW), you can change the sound of your voice and
optimally adjust it (+/-15 dB).
The AUX control adjusts the volume of the MIC AUX send
signal laid out at the rear panel MIC AUX SEND connector
(see ).
Use the VOL control to adjust the microphone signal volume.
Your PRO MIXER features a talk over function. It works very
simply: as soon as you talk into your mike while a track is playing,
the track’s volume is lowered. When talking to the audience, this
function is useful because it makes your voice come through
over the music.
Use the TALK key to activate the talk over function (its LED
is lit).
The SENS control changes the sensitivity of the talk over
function. The lower it is set, the louder does the mike signal
need to be in order to suppress the music signal.
Use the DPT control to determine the extent to which the
music signal is lowered.
Use the MIC ON switch to activate the microphone channel.
If its LED is lit, the channel is active.
2.2 Stereo channels
Select the input signal for the stereo channels using the
INPUT key. “Phono” is intended for connecting a turntable.
“Line” and “CD” have to be selected for all other signal
sources (e. g. CD or MD players). Unlike the first three
channels, channels 4 and 5 each feature two line inputs.
On the rear panel, a special feature lets you change the
input sensitivity of the phono inputs of channels 1 through
3 to line level, so that you get more flexibility (see ).
+
Never connect equipment with line level signals to
the highly sensitive phono inputs! The output signal
level of turntables is on the order of magnitude of
milivolts, while CD players and tape decks have
signal levels measuring in volts. Simply put, line
signals are up to 100 times stronger than those
intended for phono inputs. If you’re using phono
inputs that can be switched into line level (see ),
always make sure that the PHONO/LINE switch is in
its correct position (switch pressed!).
The TRIM control is used to set the level of the input signal.
The display reads off the current signal level.
Every input channel features a 3-band equalizer (HIGH,
MID and LOW) with kill characteristic. This way, a signal
can be lowered (-32 dB) much more than it can be
increased (+12 dB). For example, this function is useful
when you need to suppress a particular frequency range
in a music track.
+
The overall signal level is also dependent on the EQ
settings. You should first adjust the EQ before
adjusting the signal level.
By using the EQ BYPASS key, you can deactivate the
3-band equalizer. This way, you can easily compare the
processed and the unprocessed signals with one another;
or, you can alternate between extreme EQ settings and
the “raw” signal, creating cool effects.
You can read off the level of input signals (post EQ) using
the 4-digit LEVEL meter.
Determine the channel volume using the 60-MM CHANNEL
fader.
Pressing the PFL key routes the respective input so that it
can be monitored on the headphones (corresponding LED
is lit). You can also dial up several channels and listen to
them simultaneously (see also chapter 2.4 “HEADPHONE
section”).
2.3 MAIN OUT section
The VOL 1 control is used to adjust the output volume on
the MAIN 1 output (see ).
The VOL 2 control is used to adjust the output volume on
the MAIN 2 output (see ).
To adjust balance on the MAIN 1 output, use the BAL 1
control.
You can read off the MAIN 1 audio signal volume level on
the LEVEL METER.
The POWER switch powers the PRO MIXER on. You should
always make sure that the POWER switch is in the “Off”
position when initially connecting the unit to the mains.
When the switch is in its upper position (“I”), the VMX1000
is powered on (see fig. 2.1). When the switch is in its
lower position, the unit is off.

Please note: The POWER switch does not fully
disconnect the unit from the mains. To disconnect
the unit from the mains, pull out the main cord plug
or appliance coupler. Unplug the power cord when
the unit is not used for prolonged periods of time.
+
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
PRO MIXER before turning on the power amps. To
be sure, slide all the faders to the bottom and
switch all controls to the zero position.
2.4 HEADPHONE section
The PFL signal is your headphone signal used to monitor music
without influencing the MAIN signal (PFL = Pre Fader Listening).
This is the unbalanced PHONES connector for your
headphones. Your headphones should have a minimum
impedance of 32 Ohms. For example, the BEHRINGER
HPX2000 headphones are ideally suited for this purpose.
If the MODE switch is in the “SPLIT” position, the PFL
signal is on the left, and the MAIN signal is on the right.
The MIX control (see ) has no function in this case.
While in “STEREO” mode, you can alternate between MAIN
and PFL signals using the MIX control.
