2.1

Microphone channels

[ 1 ] These are the balanced XLR connectors for dynamic
microphones.
Using the 3-band microphone equalizer ( HIGH, MID
[ 2 ]
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
[ 3 ]
signal laid out at the rear panel MIC AUX SEND connector
(see { 38 } ) .
Use the VOL control to adjust the microphone signal
[ 4 ]
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
[ 5 ]
(its LED is lit).
PRO MIXER VMX1000USB User Manual
The SENS control changes the sensitivity of the talk over
[ 6 ]
function. The lower it is set, the louder does the mike
signal need to be in order to suppress the music signal.
[ 7 ] Use the DPt control to determine the extent to which the
music signal is lowered.
Use the MIc ON switch to activate the microphone
[ 8 ]
channel. If its LED is lit, the channel is active.
2.2

Stereo channels

Select the input signal for the stereo channels using
[ 9 ]
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 { 36 } ) . Audio sent from a computer to the
VMX via USB cable is routed to channel 1. This signal is
mixed with the LINE input.
PRO MIXER VMX1000USB User Manual
◊ 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 { 36 } ) , always make sure
that the PHONO/LINE switch is in its correct position
(switch pressed!).
The GAIN control is used to set the level of the input
[ 1 0]
signal. The display { 13 } reads off the current signal level.
Every input channel features a 3-band equalizer ( HIGH,
[ 1 1]
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
[ 1 2]
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
[ 1 3]
the 4-digit LEVEL meter.
Determine the channel volume using the
[ 1 4]
60-MM cHANNEL fader.
Pressing the PFL key routes the respective input so that
[ 1 5]
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
[ 1 6]
the MAIN 1 output (see { 41 } ) .
The VOL 2 control is used to adjust the output volume on
[ 1 7]
the MAIN 2 output (see { 46 } ) .
To adjust balance on the MAIN 1 output, use the
[ 1 8]
BAL 1 control.
You can read off the MAIN 1 audio signal volume level on
[ 1 9]
the LEVEL MEtEr.
The POWEr switch powers the PRO MIXER on. You should
[ 2 0]
always make sure that the POWER switch is in the "Off"
position when initially connecting the unit to the mains.
◊ Please take note: 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.
◊ 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
[ 2 1]
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
[ 2 2]
signal is on the left, and the MAIN signal is on the right.
The MIX control (see { 23 } ) has no function in this case.
While in "STEREO" mode, you can alternate between
MAIN and PfL signals using the MIX control.
When in "S TEREO" mode, use the MIX control to
[ 2 3]
determine which signal is heard on the headphones.
When MIX is in its left-most position (PFL), you can only
hear the headphone signal selected previously using
the PfL keys of the input channels (see { 15 } ) . When MIX is
in its right-most position (MAIN), you can only hear the
MAIN audio signal. Placing the MIX control somewhere
in between those two extreme positions determines the
volume ratio of the two signals. If the MODE switch is
in its "SPLIT" position (see { 22 } ) , the (PfL) MIX control has
no function.
The VOL control determines the volume of the
[ 2 4]
headphone signal.
2.5

XPQ 3D surround function

The XPQ 3D surround function is a built-in effect that
gives your music a nice finishing touch, making every
performance truly memorable. By widening the stereo
base, the sound comes through more alive and transparent.
Using the XPQ ON switch { 25 } activates the XPQ 3D surround
function (corresponding LED is lit) and the XPQ control
{ 26 }
determines the intensity of the effect.
2.6

Effects loop

[ 2 7] Using the rEt control, you determine the volume of the
effects signal that can be brought in at the RETURN input
on the rear (see { 49 } ) . To get the effects signal, you need to
connect the inputs of an effects unit to the SEND outputs
(see { 48 } ) of your VMX1000USB. The outputs of the effects
unit are then connected to the RETURN inputs of your
mixer.
