VIRTUALIZER PRO DSP2024P
1. INTRODUCTION
In purchasing the BEHRINGER VIRTUALIZER PRO you have acquired an extremely efficient multi-effects
processor that offers first class reverberation effects and a number of other algorithms. The DSP2024P has 71
new effects types, and thanks to its logically structured user interface, it can be used easily and intuitively.
In order to generate an extremely natural reverberation, we at BEHRINGER have developed new kinds of
algorithms for virtual acoustics.These algorithms will help you calculate all room and reverberation parameters
with absolutely professional quality and naturalness.
In spite of this extensive and calculation-intensive work performed by the 24-bit processor in the DSP2024P,
the VIRTUALIZER PRO is very easy to handle. hanging parameters to achieve a specific sound is simple.
There are 100 presets available to store your own programs.
The DSP2024P includes excellent reverb and delay programs, but thats not all. Besides the classic plate
reverb simulations, the VIRTUALIZER PRO will impress you with its excellent modulation effects (like chorus,
flanger and phaser), which were extended to include special variations like a musical pitch shifter, a tremolo,
and a rotary speaker simulation. The DSP2024Ps dynamic and psycho-acoustic effects allow you to do
without a number of additional pieces of equipment. The DSP2024P also offers you a series of distortion and
amplification sounds that are combined with a speaker simulation. Thus, as a guitarist in recording
situations, you can achieve an excellent sound on tape or hard disk, even without a speaker cabinet. Besides
its logical and simple operation, the VIRTUALIZER PROs technical equipment is also impressive. The following
points ensure signal processing at a professional level:
sExtremely low-noise and exact 24-bit A/D and D/A converters.
sA professional sample rate of 46 kHz guarantees a high signal resolution for a frequency response of 20 Hz
to 20 kHz.
sThe 24-bit processor features dual engine software; these two sections process audio input independently.
sAs for all BEHRINGER products, the highest quality components and controls are used.
+The following instructions will give you a brief run-down on the terminology and functions of
the VIRTUALIZER RO. After reading, please store this manual in a safe place for future
reference.
1.1 The concept
BEHRINGER uses an uncompromising selection of components. The heart of the BEHRINGER
VIRTUALIZER PRO is a 24-bit DSP, which, due to its exceptional technical specifications, is regarded as one
of the finest building blocks. With it come the first class 24-bit A/D-D/A converters, guaranteeing a precise
conversion of audio signals. Narrow-range tolerance resistances and capacitors, high-grade switches, and
other selected components are all very high in quality.
The VIRTUALIZER PRO was manufactured on the basis of SMD technology (Surface Mounted Device). The
use of sub-miniature building blocks known from space flights allows not only an extreme packing density but
also ensures an increased dependability. The DSP2024P was manufactured under ISO9000 certified
management system.
1.2 Before you get tarted
The VIRTUALIZER PRO was carefully packed in the factory to ensure safe transport. Nevertheless, if the box
shows signs of damage, please check the equipment immediately for any signs of external damage.
+Damaged units should NEVER be sent directly to us. lease inform the dealer from whom you
acquired the unit immediately as well as the transportation company from which you took
delivery of the unit. Otherwise, all claims for replacement/repair may be rendered invalid.
1. INTRODU TION

VIRTUALIZER PRO DSP2024P
+To assure optimal protection of your DS 2024 during use or transport, we recommend utilizing
a carrying case.
+lease always use the original packaging to avoid damage due to storage or shipping.
+Never let unsupervised children play with the DS 2024 or with its packaging.
+lease dispose of all packaging materials in an environmentally-friendly fashion.
The BEHRINGER VIRTUALIZER PRO requires one standard 19" rack unit of space (1 3/4"). Please leave an
additional 4" installation depth to allow connections at the rear side.
Make sure that there is adequate ventilation and do not place the VIRTUALIZER PRO on top of an amplifier,
which could cause overheating.
+Before connecting the VIRTUALIZER RO to the mains, carefully check that your equipment is
set to the correct voltage:
The fuse holder on the female mains connector has 3 triangular markings, with two of these triangles opposing
each other. The VIRTUALIZER PRO is set to the operating voltage printed next to these markers and can be
set to another voltage by turning the fuse holder by 180°. CAUTION: This instruction does not apply to
export models exclusively designed, e.g. for 120-V operation!
onnection to the mains is made by a mains cable with an IE receptacle that complies with the required
safety regulations.
+lease make sure that the unit is grounded at all times. For your own protection, you should
never tamper with the grounding of the cable or the unit itself. The unit shall always be
connected to a mains socket outlet with a protective earthing connection.
+Installation and operation of this equipment must be carried out by competent staff only. Both
before and after installation, the staff using the equipment should make sure that it is properly
grounded since otherwise electrostatic discharge etc. can lead to an impairment of its
operation. For more information, see chapter 6 INSTALLATION.
The BEHRINGER VIRTUALIZER PRO is equipped with electronically servo-balanced inputs and outputs. The
circuit design features automatic hum suppression for balanced signals and thus ensures trouble-free
operation, even at the highest operating levels. Externally induced mains hum, etc. can therefore be effectively
suppressed. The automatic servo-function recognizes the presence of unbalanced connectors and adjusts the
nominal level internally to avoid level differences between the input and output signals (6-dB correction).
The MIDI connectors (IN/OUT/THRU) are standard DIN plug connections. The data communication is isolated
from ground by opto-couplers.
1.3 Control element
Fig. 1.1: VIRTUALIZER PRO front panel
The BEHRINGER VIRTUALIZER PROs front panel includes five edit controls (non-intermittent rotary controls),
a jog wheel (big rotary control), six parameter keys, an LED display and a mains switch. Each of the two fully
independent channels can be monitored with an 8-digit LED meter.
1. INTRODU TION

VIRTUALIZER PRO DSP2024P
Fig. 1.2: Display se tion of the VIRTUALIZER PRO
1
Both the LED CHAINS display the intensity of the input signal in dB in relation to the nominal level,
which is selected on the rear panel with the OPERATING LEVEL switch.
2
After you switch on the VIRTUALIZER PRO, you can read the name of the last used effect on the LED
DISPLAY. When editing, the LED DISPLAY shows the parameters name along with a 4-digit
alpha-numeric display that shows the absolute parameters value.
3
To the right of the LED DISPLAY are four STATUS LEDs which indicate the type of value you are
working with. You may do any of the following:
s set the absolute value of an effect parameter (%),
s increase or decrease the amplitude or determine the threshold point of the compressor (dB),
s modify a frequency (Hz) or
s modify a time parameter (sec).
4
The ALGORITHM GROUPS LED CHAIN indicates which category the selected effect belongs to.
Altogether the DSP2024P offers eight different algorithm groups.
Fig. 1.3: Fun tion keys, ontrols and jog wheel
5
Every preset in the DSP2024P allows you to edit at least four effect parameters. The EDIT-LED-CHAIN
indicates which parameters are adjusted by the four EDIT ONTROLs. If the top LED lights up,
controls the parameter EDIT A, controls EDIT B, helps in changes of parameter EDIT and
with you change the setting of parameter EDIT D. If the middle LED of the EDIT-LED- HAIN lights
up, the four EDIT ONTROLs modify the parameters that are arranged to its left and right. The lower
LED functions correspondingly.
+For the exact meaning of the individual effect parameters, see chapter 7.1.
1. INTRODU TION

9
VIRTUALIZER PRO DSP2024P
6
With the 1st EDIT CONTROL (non-intermittent rotary control) you change the values of the first (EDIT A)
and fifth (EDIT E) effect parameters. You can also select MIDI functions (MIDI) with the 1st EDIT
ONTROL. Press the EDIT key to switch from EDIT A to EDIT E and vice versa. You reach the MIDI
function by pressing the SETUP key .
7
The 2nd EDIT CONTROL allows you to modify the values of effect parameters EDIT B and EDIT F.
When you select the IN UT parameter with the help of the SETUP key, you can specify whether the
DSP2024P functions mono or stereo mode (see chapter 3.6.2 for more information).
8
The 3rd EDIT CONTROL modifies the values of effect parameters EDIT C, EQ LO, and the global
OUT UT parameter (see chapter 3.6.3). Here, as well, you select among them using the EDIT and
SETUP keys.
9
With the 4th EDIT CONTROL, you modify the values of effect parameters EDIT D, EQ HI, and the global
parameter CONFIG (see chapter 3.6.4). Use the EDIT and SETUP keys to choose between the
parameters.
+During editing, you can rotate one of the four EDIT CONTROLs minimally to display a brief
description of the current parameter active. This can help you know that, for example, EDIT A
controls the pre delay for all reverb effects of the VIRTUALIZER RO. After approximately one
second the name is erased and the parameters current value is displayed. This function can
be used only by operating one of the controls that has not yet been selected.
10
By turning the MIX/BYPASS CONTROL the effect levels of most effect algorithms are set in the range
from 0 to 100%. If you select 0%, the signal at the inputs of DSP2024P is transferred directly to the
outputs without adding any effects (the signal is completely dry). If you select 100%, only the effected
signal is sent to the outputs (the signal is completely wet).
+If you use the DS 2024 in the aux bus with your mixing console, you should always set this
value at 100%. if youre using the DS 2024 with a guitar amplifier (in a serial effects loop), we
suggest settings between 20 and 50% (depending on the amplifier type).
+lease note that, for the effects parametric and graphic EQ, the MIX/BY ASS CONTROL
allows a gain correction by rotation.
To bypass the DSP2024Ps effects, press the MIX/BYPASS ONTROL. This allows you to compare
between the original and the effected signals. Press the MIX/BYPASS ONTROL again to deactivate
the bypass and return to your chosen effect. When the MIDI IN LED below the control flickers, it
indicates that MIDI data is arriving at the MIDI IN port.
+Both the MIX/BY ASS CONTROL and the four EDIT CONTROLs react dynamically. This means
that, depending how fast you rotate the wheels, the present parameter is changed in steps of
1, 2, 5 or 10. The faster the rotation, the greater the change in the parameter value.
11
To select one of the 200 presets, press the PRESET key once, then rotate the JOG WHEEL .
12
To select one of the 71 basic effect algorithms, press the EFFECT key once, then rotate the JOG
WHEEL. For information on the parameter values that are set for the basic effect algorithms, see
chapter 7.4.
13
To select the EDIT ONTROL function (see - ), press the EDIT key.
14
When you make changes to a user preset, the STORE keys LED begins to blink. The DSP2024P
comprises 100 user presets for your own settings and 100 factory presets (see separate preset sheet).
To save your changes, press the STORE key. Select a storage space (number) with the JOG WHEEL
and confirm it by pressing the STORE key again.
15
If you have made changes to a preset and the LED of the STORE key is blinking, you can press the
COMPARE key to temporarily restore the presets original settings. While these settings are loaded,
the OMPARE keys LED blinks and  OMP appears in the LED DISPLAY. Press the OMPARE key
again to return to edit mode and store your changes.
16
To enter SETUP mode, press the SETUP key. In setup mode, you can access the parameters shown
below the four EDIT ONTROLs. For more information about SETUP mode, see chapter 3.6.
1. INTRODU TION

10
VIRTUALIZER PRO DSP2024P
17
To change a parameters value, rotate the JOG WHEEL. To increase the value, turn the wheel clock-
wise. To decrease the value, turn the wheel counterclockwise. If none of the edit functions is selected,
you can select a program directly with the JOG WHEEL. When you do so, a spot lights up in the LED
DISPLAY. As long as the spot is illuminated, a program can be selected without making the
corresponding settings immediately audible. This brief signal suppression means that during quick
selection of presets with the JOG WHEEL, not every preset is activated directly. If the JOG WHEEL is
not turned for a second, the spot in the LED DISPLAY disappears and the program is loaded.
18
Use the POWER switch to power up your DSP2024P. The POWER switch should always be in the Off
position when you are about to connect your unit to the mains.
+To disconnect the unit from the mains, pull out the mains cord plug. When installing the
product, ensure that the plug is easily accessible. If mounting in a rack, ensure that the mains
can be easily disconnected by a plug or by an all-pole disconnect switch on or near the rack.
Fig. 1.4: VIRTUALIZER PRO rear panel
19
FUSE HOLDER / VOLTAGE SELE TION. Before connecting the DSP2024P, confirm that the voltage
display matches your local mains voltage. When replacing the fuse, you must always use the same
type. In many units the fuse holder can be installed in one of two positions, allowing you to switch
between 230 V and 120 V. If you wish to operate a unit outside Europe at 120 V, then a stronger fuse
must be used. (For more information, see chapter 8 SPE IFI ATIONS). The mains connection is made
via the IE receptacle. An appropriate mains cable is included.
20
The DSP2024P has wide-ranging MIDI implementation. MIDI IN, MIDI OUT, and MIDI THRU connectors
are available for transmitting MIDI commands.
21
SERIAL NUMBER. Please complete and return the warranty card within 14 days of the date of
purchase. Otherwise, you will lose your right to the extended warranty. Alternatively, you can register
online at our website under www.behringer.com.
22
The DSP2024Ps balanced OUTPUTs are designed as 1/4" TRS and XLR sockets.
23
To switch between -10 dBV (home recording level) and +4 dBu (professional studio level), use the
OPERATING LEVEL SWITCH. When you switch between the two, the level displays are automatically
changed to the nominal level and the VIRTUALIZER PRO operates in its optimal working range.
24
Both of the VIRTUALIZER PROs INPUTs are also available as balanced 1/4" TRS and XLR sockets.
2. EFFECTS ALGORITHMS
All effects of digital effects equipment are based on various algorithms. An algorithm for a reverb effect, for
example, is programmed differently than a chorus algorithm. Each effect has a certain algorithm with which the
digital input signal is processed. The processing takes place within the digital signal processor (DSP). After
the effect is generated and the input signal is mixed, the digital signal is converted back into an analog signal
with a D/A converter.
You can edit up to seven parameters for each preset in the VIRTUALIZER PRO. The changes you make will
influence the sound in different ways. An overview of the DSP2024Ps various effects algorithms follows.
