PRO MIXER VMX100USB User Manual
2.1 Input channels 1 and 2
(1)
The PHONO/LINE-USB switch selects one of the input pairs on the
respective channel. The “PHONO” setting (and inputs) are intended for
turntables; for all other signal sources, i.e. a CD or MD player, use the “LINE”
setting and inputs. Audio sent from a computer to the VMX via USB cable is
routed to channel 1. This signal is mixed with the LINE input.
◊
Never connect line-level equipment to the highly sensitive phono
inputs! The output levels of phono cartridge systems are in the
millivolt range, whereas CD and MD players, as well as tape decks,
provide outputs levels in the volt range. In other words, the level of line
signals is up to 100 times higher than phono output 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-
BAND 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)
).
(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 VMX100USB.
◊
In PFL mode, the channel 1 signal is displayed 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 VMX100USB’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 (
(11)
).
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 (
(12)
): 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 BEAT ASSIST button (
(13)
)
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 (
(14)
).
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 (
(15)
) below the TEMPO DIFFERENCE display.
When the center LED is lit, the tracks are in sync with each other. When 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.
◊
Flipping the CURVE switch may cause a sudden change in volume.
We recommend not changing this setting while a signal is present.
(18)
The
MIC INPUT
connector is a balanced 1/4
"
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
supply acceptable audio quality or corrosion protection.
(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.
