Thank you for the confidence you have placed in us by
purchasing the ULTRAVOICE DIGITAL VX2496. With the
ULTRAVOICE DIGITAL you have acquired an extremely powerful
device for creatively processing your music. Its professional
design means the VX2496 can produce excellent results, both in
the studio and live. Numerous features, such as the opto
compressor or the voice-optimized EQ mean you can even
process signals with a very wide dynamic range and tailor them
to the overall sound of your music. In addition, the VX2496 has a
digital AES/EBU output with a high-resolution 24-bit/96 kHz A/D
converter and a wordclock input enabling synchronization to
external devices.
The BEHRINGER ULTRAVOICE DIGITAL combines a microphone
preamp, control amplifier and equalizer and is ideally suited for
connection to a hard disk recording system where you could,
for example, record vocals directly onto the hard drive. The
highest quality is maintained, as any potential deterioration caused
by inserting into a mixing console is eliminated. In addition, the
integrated A/D converter ensures optimum conversion of the
analog signal with no degradation of sound quality. And, due to
its professional signal-processing features, the ULTRAVOICE
DIGITAL is also the ideal tool for optimizing live vocals.
To familiarize yourself with the functions of the VX2496, simply
connect any audio signal and try out each individual control. Use
a relatively uncompressed signal (for example, one of your own
recordings) in order to judge the effect of the opto-compressor.
CDs are usually pre-compressed, which makes it difficult to
hear how the compressor changes the sound.
Once you have developed a feel for the individual components,
you can unleash your creativity by combining individual functions.
The SIG LED above the gain control illuminates when an
input signal is present.
This manual first describes the terminology used,
so that you fully understand the VX2496 and its
functions. Please read the manual carefully and keep
it for future reference.
Ensure that the CLIP LED lights up only with peak signals.
If it is constantly lit or if distortion can be heard, reduce the
input level using the GAIN control.
1.1 Before you get started
Your ULTRAVOICE DIGITAL was carefully packed in the
factory, and the packaging is designed to protect the unit from
rough handling. Nevertheless, we recommend that you carefully
examine the packaging and its contents for any signs of physical
damage, which may have occurred during transit.
If the unit is damaged, please do NOT return it to
BEHRINGER, but notify your dealer and the shipping
company immediately. Otherwise, claims for damage
or replacement may not be granted.
The ULTRAVOICE DIGITAL has a low-cut filter which can
be used to remove low-frequency interference from the
microphone signal. This function is activated with the
LO CUT button. This filter has a slope of 12 dB/oct.
With the FREQUENCY control, you can select the cutoff
frequency below which the low-frequency component will
be removed (range 15 - 360 Hz).
The Ø INV shifts the input signal phase by 180°. Use this
function if the use of multiple microphones results in
cancellations of specific frequency ranges.
2.2 Expander and tube emulation
Be sure that there is enough space around the unit for cooling
and, to avoid overheating, please do not place your
ULTRAVOICE DIGITAL on power amplifiers, etc.
The mains connection is via the enclosed power cord and a
standard IEC receptacle. It meets all international safety
certification requirements.
Please make sure that all units have a proper
ground connection. For your own safety, never
remove or disable the ground conductor from the
unit or the AC power cord.
Before you connect your ULTRAVOICE DIGITAL to the
mains, please make sure that the voltage setting on
your unit matches the local voltage! The fuse holder above
the AC power connector has 3 triangular markings. Two of
these three triangles are aligned with one another. The VX2496
is set to the voltage shown next to these markings and can be
switched over by turning the fuse holder by 180°. IMPORTANT:
This does not apply to export models designed exclusively
for 120 V operation!
Fig. 2.2: Expander and tube emulation
An expander reduces the volume of a signal in lowlevel passages. This way, interference such as tape
noise and spill can be removed.
The IN/OUT button switches the expander in or out of the
signal path.
The THRESHOLD control determines the level at which
the expander cuts in.
2.1 Discrete vintage input stage
The amount of gain reduction is determined using the
DEPTH control. The higher the value, the more the gain is
When the GATE button is pressed, the expander functions
as a noise gate. This has a more radical effect on the
sound, as it not only attenuates but also completely
eliminates low-level passages. For this reason the gate
function should primarily be used with individual signals,
thus not risking any unwanted effect on the existing
The four GAIN REDUCTION LEDs display the amount of
gain reduction from -5 to -30 dB.
Fig. 2.1: Discrete Vintage input stage
This section of the ULTRAVOICE DIGITAL is a preamp
where you regulate the input level of the microphone or
line level signal.
Use the LINE button to select the type of input signal
(pressed = LINE, not pressed = MIC).
Press the +48 V button to power a condenser microphone.
Dynamic microphones do not require this phantom power
The GAIN control sets the input level. The scale -12 to
+12 dB relates to the LINE input whereas the scale +10 to
+60 dB relates to the MIC input.
The tube emulation function allows you to enhance
vocals with subtle distortion and tape saturation effects,
replicating analog tapes and tube amps. In this mode,
the VX2496 adds upper harmonics to the signal, thus
enhancing its sound in the high-frequency range.
The IN/OUT button activates or deactivates tube emulation.
The DRIVE control determines the intensity of the saturation
effect. The further it is turned to the right (HOT), the greater
the effect. The amount of upper harmonics generated is
also dependent on the level set at the discrete vintage
input stage.
The SIG LED lights up when tube emulation is active.
To avoid internal overloading, the CLIP LED should only
light up during peak level passages. It should not be
constantly illuminated.
The TUNING control lets you determine the frequency range
to be saturated. All other ranges remain unaffected,
allowing the effect to be finely tailored.
2.4 Voice-optimized EQ
To process the whole frequency spectrum, use the FULL
BW button. This makes the TUNING control inoperative.
2.3 Opto compressor
Fig. 2.4: Voice-optimized EQ
The voice-optimized EQ is a 3-band equalizer used for
sound shaping. You can boost or cut frequency ranges
in order to equalize weaknesses in the input signal.
Activate the voice-optimized EQ with the IN/OUT button.
Fig. 2.3: Opto compressor
The opto compressor reduces the dynamic range of
the input signal, i.e. the level difference between soft
and loud passages. Peaks above a certain value are
reduced, smoothing out the sound.
The IN/OUT button activates the compressor. Use this to
directly compare compressed and uncompressed signals.
The THRESHOLD control determines the level at which
the opto compressor starts to compress the signal. Only if
this value is exceeded will the signal be processed. The
dynamics of passages whose levels lie below the threshold
are not affected. The lower the threshold value, the greater
the compression.
The HARD RATIO button sets the amount of signal gain
reduction to its maximum. This produces a highlycompressed, flat sound. Do not use this function if you
wish to retain the natural dynamics of the sound.
If the FAST button is pressed, the opto compressor starts
compressing very quickly after the threshold is exceeded.
The overall sound appears significantly more compressed
and the result is a very powerful sound.
Use the TUNING control to select a frequency range
(130 Hz to 720 Hz).
The selected frequency range can be boosted or cut using
the WARMTH control. Cut employs a narrower bandwidth
than that used for boost, enabling you to tailor the filter to
your specific needs.
Use the PRESENCE control to add high and upper-mid
frequencies to the signal (around 1.7 kHz). This helps to
push vocals to the forefront with more presence in the
overall sonic image.
Use the BREATH control to boost or cut typical noises
associated with the voice (e.g. breathing) at around 8 kHz.
The ABSENCE button cuts the level of those frequencies
that cause an unappealing, harsh sound. These lie around
the area of 4 kHz.
2.5 Opto de-esser and master section
The RELEASE control determines how quickly the
compression stops after the signal falls back below the
threshold. The longer the release time, the more compressed
the sound will appear to be, but also the more smoother.
The OUTPUT control regulates the output volume of the
compressed signal. The compression process reduces
the level of signal and this control is used to raise its level
again (known as make-up gain).
Certain frequency ranges may be lost during compression.
These can be regained by using the integrated enhancer.
The sound is subjectively rounded off and acquires a new
The six GAIN REDUCTION LEDs display the amount of
compression. The level reduction displayed ranges from
-3 to -24 dB.
Fig. 2.5: Opto de-esser and master section
Sibilance is an unwanted effect that can occur with
some voices, whereby hissing sounds like that of “s”
or “sh” are produced. With the opto de-esser, sibilance
can easily be removed from the signal.
Depress the IN/OUT button to activate the opto de-esser.
The THRESHOLD control determines the amount by which
sibilance should be suppressed. The lower the value, the
more comprehensively sibilance is removed.
Use the CUT FREQ control to select the frequency range
to be reduced.
The ACTIVE LED lights when the opto de-esser is
functioning. The intensity of the LED reflects how hard the
opto de-esser is working.
To avoid coloring the character of the sound, do not
set the threshold too low when using the opto
de-esser. When the threshold is set at its optimal
value, the effect should only be recognizable by
direct comparison to the unprocessed signal using
the IN/OUT button.
The LINE input is on a balanced 1/4" TRS jack.
Use the MASTER FADER to match the output signal level
to the input sensitivity of the following device (e.g. your
DAT or hard disk recorder).
Start by tuning the master fader right down and
increase it slowly to the desired level. If you start
with too high a level, you risk overloading the inputs
of the devices that follow!
The six OUTPUT LEVEL LEDs show the level of the output
over a -10 to +15 dB range. Ensure that the output level
does not go into overload otherwise the signal at the
DIG OUT output will be too high and cause distortion.
Use the POWER button to turn on the ULTRAVOICE DIGITAL.
This is the balanced XLR connector for a microphone (MIC)
or line source.
When the Line key
is pressed, XLR and the jack
connector are connected in parallel. If one line
signal is fed into both inputs at the same time, the
overall level of the output signal becomes lower,
and both signals are mixed with one another in the
same ratio.
Please avoid connecting a mic and a line-level signal
(CD player, sound card) to the input of your VX2496
at the same time. The low impedance of the
microphone would make the line signal barely
audible. Additionally, this could also damage the mic.

FUSE HOLDER/VOLTAGE SETTING. Before connecting the
unit to the mains, ensure that the voltage setting matches
your local voltage. A blown fuse should only be replaced
by a fuse of the same type and rating. On some units, the
fuse holder can be switched to one of two positions, i.e.
230 V and 120 V.
Should you desire to operate the unit outside Europe
at 120 V, a higher fuse rating is required (see
chapter 1.1).
The mains connection is on an IEC receptacle. An
appropriate power cord is included.
SERIAL NUMBER. Please take the time to complete and
return the warranty card within 14 days after the date of
purchase to benefit from our extended warranty. Or simply
register online at The serial number
needed for the registration is located at the top of the unit.
Use the SAMPLING RATE switch to select the sampling
rate at which the VX2496 analog signal is converted. You
can choose a sample rate frequency of 44.1, 48, 88.2 or
96 kHz. If you want to lock to an external wordclock, the
SAMPLING RATE switch should be set to EXT.
Wordclock for synchronization of the VX2496 can be fed
from an external device into the WC IN input. This connector
is a BNC coaxial jack and is only active when the SAMPLING
RATE switch is set to EXT.
The ULTRAVOICE DIGITAL VX2496 features a 24-bit/96 kHz
A/D converter with digital AES/EBU output. This allows you to
record the digital output direct onto a digital medium without the
need of an external A/D converter. Thus the ULTRAVOICE DIGITAL
can be seamlessly integrated into a hard disk recording system.
When several digital devices are integrated into a digital
recording system with, for instance, a digital mixing console, all
the digital devices must be synchronized to a common wordclock
signal. For this reason the VX2496 has a wordclock input which
enables it to be locked to an external device. It supports all
sampling rates from 32 to 96 kHz.
Fig. 2.7: ULTRAVOICE DIGITAL connections
These are the MAIN outputs of the ULTRAVOICE DIGITAL
on balanced XLR and 1/4" TRS jacks.
The XLR RECORDING output is for connection to a DAT
recorder, hard disk recorder or similar device and is sourced
pre de-esser.
This is the INSERT section with two 1/4" mono jacks as
SEND and RETURN for connecting an additional effects
device. The signal is sourced post low-cut filter of the
input stage.
When recording with the ULTRAVOICE DIGITAL, you should
strive to achieve as natural a sound as possible at the best
possible quality. During the mix the signal can then be given any
required special treatment, with the original recorded signal
always remaining pure.
Set an appropriate input level using the discrete vintage
input stage’s GAIN control.
Be sure to do everything possible to achieve the best sound
before it reaches the ULTRAVOICE DIGITAL. This includes
being especially careful to find the optimal position for the
microphone and ensuring that the surrounding acoustics
enhance the sound in the desired fashion.
Then, turn all the ULTRAVOICE DIGITAL controls off to
initialize the “dry” signal.
If necessary you can then smooth out the dynamics of the
vocal slightly with the opto compressor. Be sure not to
compress the signal too much; the compressor can always
be used again after the recording. Also, do not use the
hard ratio function at this stage as it makes a very audible
difference in the signal. If the vocalist constantly changes
his distance from the microphone during recording, extreme
dynamic fluctuations may result. In this case, a higher
level of compression should be used. Keep the threshold
relatively low on the opto compressor to obtain a normal
volume level.
To avoid having to compress the signal too much,
try to maintain a constant distance between the
vocalist and the microphone while recording.
Backing vocals should be highly compressed so they can be
present throughout the recording without volume fluctuations.
The voice-optimized EQ allows you to equalize deficiencies
in the sound image that could not be corrected in advance.
However, do not use extreme settings here either, as you
can add more EQ when mixing. The voice-optimized EQ
can be used to deal with the following problems:
s If the vocals sound muddy in the bass range, you
can cut the low-frequency area of the signal by using
the WARMTH control. Set the control to full cut and
locate the intrusive frequency range with the TUNING
control so that the voice sounds more balanced.
You should try this in solo mode first. Then, listen
to the voice with the rest of the mix and adjust the
WARMTH control until the overall sound is right.
s If the voice sounds too edgy, use the ABSENCE button
on the voice-optimized EQ. This will attenuate these
harsh frequencies without compromising the natural
quality of the overall sound. In addition, you can boost
the low frequencies with the WARMTH control or, if
necessary, improve the peaky characteristic of the
signal by lowering the BREATH or PRESENCE control.
s If the voice is getting lost in the mix, increase the
PRESENCE control. Boosting this range will help the
voice to cut through more.
s If the vocal sound is not brilliant enough, you can
add peaks using either the PRESENCE or the
BREATH control. Additionally, you can use the
opto-compressor enhancer to add upper harmonics
If the signal contains unwanted frequency areas, use the
expander and the opto de-esser to remove them. Sibilance
can be removed with the opto de-esser, but first you must
isolate the intrusive frequency range:
s Activate the voice-optimized EQ and turn the BREATH
control up to exaggerate sibilant frequencies. If you
have already used the EQ, first make a note of the
original settings so they can be subsequently reset.
s Activate the opto de-esser and, using a low
threshold, turn the CUT FREQ control until the
sibilance is reduced.
s Now turn the voice-optimized EQ off again and reset
the BREATH control to its original position.
s Now set the threshold so the ACTIVE LED only lights
up when sibilance is present.
The expander enables you to remove intrusive noise from
quiet passages. To do this, turn the THRESHOLD control to the
far left and turn it up slowly with DEPTH set at medium. Find the
value at which you notice an audible suppression of the quiet
spots without impairing the vocal sound.
Only use the gate in exceptional cases—if, for instance, you
want to achieve a specific effect. It radically affects the sound
and could thus ruin your recording.
Use the tube emulation for a “classic” analog tape recording
Finally, use the MASTER FADER to regulate the
Go ahead and experiment with the mixing possibilities of the
ULTRAVOICE DIGITAL and push it to its limits. It is often the case
that extreme effect and filter settings are needed to optimally
integrate a signal into the mix. If a voice ultimately appears as
very full and present in the mix, it usually means the signal has
been thoroughly and truly “tweaked”.
Vocals usually have reverb added during the mix. If you notice
intrusive noise (e.g. sibilance) in the reverb, use the opto
de-esser to remove it as follows:
s Remove the sibilance from the vocal as previously
described in chapter 3.5 and drive the reverb unit
via one of the main outputs (not via the INSERT path
as it is sourced before the de-esser). Make sure
the reverb unit is set to 100% wet, i.e. there is no
dry direct signal present.
s The reverb signal can now be mixed at the console
with the signal from the VX2496’s RECORDING output.
This is sourced before the de-esser, and in this
way sibilance is removed only from the reverb
signal, not the main voice itself.
The expander can be used to remove spill from other
instruments which, for example, may have been picked up by
the microphone from the vocalist’s headphones. Remember that
compression would have the opposite effect, as the signal is
limited at the loudest spots. Any spill would then become
effectively louder.
Although the ULTRAVOICE DIGITAL was principally designed
to record vocals, you can of course also use it to record and mix
other signals.
4.1 Hints about analog output level setting
The output level meter has been calibrated to +4 dBu. For Main
Out, this means the following: if OUTPUT LEVEL METER shows
0 dB, +4 dBu is connected to Main Out. This way, you have
positioned the optimal level of the output signal in order to create
maximum rejection with sufficient headroom.
Hint: Some equipment requires a lower input signal level
(-10 dBV; in home recording domain). Use the input signal level
displays of such equipment as well as the output level control of
the VX2496 to create optimal adjustments.
4.2 Hints about digital output level setting
The maximum level for digital signals is 0 dBFS. If the OUTPUT
LEVEL-LEDs indicate +15 dB, this signal level is located at the
digital output of the VX2496. Always keep in mind that a signal
level higher than 0 dBFS/+15 dB will immediately lead to harsh
distortion. Therefore, we suggest that you always stay well
below this value in order to avoid distortion and increase
headroom for signal peaks.
Please always make sure that the clip LED at the
input is seldom or never lit.
The ULTRAVOICE DIGITAL is a versatile problem-solver and
sound-shaper both in live and studio environments.
On a small stage, short distances between the microphone
and the monitor speaker can lead to unpleasant feedback. In this
case the VX2496 opto de-esser could be used to suppress
s Set the THRESHOLD control relatively low.
s Use the CUT FREQ control to find the frequency
causing the feedback.
s Now turn the threshold up far enough to eliminate
the feedback while maintaining an unaffected vocal
signal as much as possible.
Loud volume can lead to large amounts of spill on stage, i.e.
the microphones do not just pick up one signal (e.g. vocal), but
many other signals from the stage. This can be a major problem,
as the individual signals cannot be easily controlled independently.
Use the expander to isolate individual signals and to lessen of
spill. The level of the spill is lowered while the louder wanted
signal is unaffected. The gate function also lends itself well to
this application as unwanted signals can be completely eliminated
in this way. You must be careful, however, to ensure that the
main signal is not clipped as the gate cuts off when it falls below
the threshold. This could even cause quiet passages to disappear
even though they are meant to be heard. The gate is also ideally
suited to processing impulse sounds (e.g. snare, bass drum,
toms etc.) as these are relatively short signals that neither swell
nor ring out.
Fig. 7.2: 1/4" TS connector
As mentioned at the beginning of this manual, the
ULTRAVOICE DIGITAL is ideally suited to direct connection to a
recording medium, such as a DAT recorder, analog tape machine,
or even a hard disk recording system without the use of a mixing
console. Furthermore, an extremely clean signal is produced as
the potential noise produced by looping through a mixing console
is eliminated from the outset. You can integrate the VX2496 into
a hard disk recording system without having to use an additional
A/D converter. For such cases, the ULTRAVOICE DIGITAL has a
24-bit/96 kHz A/D converter with digital AES/EBU output. The
wordclock input allows the VX2496 to be locked to external
devices. Of course, you can also successfully integrate the
ULTRAVOICE DIGITAL into your studio conventionally with a
mixing console.
for the insert connectors—standard electronically servobalanced inputs and outputs. The circuit design has automatic
hum suppression with balanced signals and operates problem
free even at high levels. Externally-induced mains hum is thus
efficiently suppressed. The servo-function automatically detects
when connector pins are unbalanced and changes the nominal
level internally by 6 dB so that there is no difference in level
between input and output signals.
Please ensure that only qualified persons install
and operate the device. During installation and
operation the user must have sufficient electrical
contact to earth. Electrostatic discharges might
affect the operation of the unit.

7.1 Advice about using an adapter for
converting from the AES/EBU to
the S/PDIF format
The VX2496 makes the digital signal available in the AES/EBU
format. If you want to connect equipment that receives a digital
signal in the S/PDIF format, you will need an adapter. Please note
that different standardization of both formats may lead to
problematic adapter performance.
Normally, this is how the polarity of the AES/EBU connector is
laid out: 1=GND, 2=HOT, 3=COLD.
Figure 7.4 clarifies the design of the adapter. Keep in mind that
the connection between different pieces of equipment should
be as short as possible.
