VIRTUALIZER PRO DSP1024P
1. INTRODUCTION
With the BEHRINGER VIRTUALIZERPRO you have purchased a very powerful multi-effects processor which
offers both first-class reverb sounds and various other effect algorithms. Although you will find a high number of
effect types 32 newly developed effect types with more than 700 variations the VIRTUALIZERPRO can be
operated easily and intuitively with its logically structured user interface.
To generate reverberation that is very natural in character, we at BEHRINGER developed innovative virtual
acoustics algorithms which allow for computing all room and reverb parameters with absolute pro-level quality
and a highly natural sound character.
Despite extensive computing work which is done in the DSP1024P by a dual-engine 24-bit processor, the
VIRTUALIZERPRO can be operated easily and conveniently. All parameter edits are performed with the jog
wheel (rotary control). 100 presets are available to store user-defined programs.
However, the DSP1024P is by no means limited to excellent reverb and delay programs. In addition to the
simulation of classic plate reverbs, the VIRTUALIZERPRO gives you extraordinary modulation effects (such
as chorus and flanger), plus a few special-purpose variants, e.g. a musical pitch shifter as well as tremolo and
rotary speaker simulations. With the vocoder and vocal distortion effect programs, you even have ultra-modern
effects available that the DSP1024P generates with absolute realism.
A very special feature are the high and low filters which can be freely edited and directly selected in each
preset. With these filters you can fine-tune the sound of your presets to match any given room characteristics
a time saving feature especially for live applications, where every second counts. Additionally, the DSP1024P
offers delay times of up to 5.1 seconds in stereo mode. Not only will the VIRTUALIZERPRO convince you with
its logical and easy-to-operate user interface, its technical features, too, are quite impressive. The following
criteria ensure the pro-level processing of audio signals:
s Extremely low-noise and high-precision 24-bit AD/DA converters.
s A professional sampling rate of 46 kHz ensures a high signal resolution with a frequency response ranging
from 20 Hz to 20 kHz.
s The 24-bit processor features two sections (dual-engine software), each processing one independent audio
channel.
s Like all BEHRINGER products, the DSP1024P uses only high-grade components and circuitry.
With its complete MIDI implementation the DSP1024P can be integrated in any MIDI system. Our free
VIRTUALIZERdesign MIDI software editor (available at www.behringer.com) enables you to program the
VIRTUALIZERPRO from your personal computer, and the MIDI interface allows for transmitting data from the
DSP1024P and store them on an external storage medium. For example, you can use sys-ex dumps to send
all presets and settings to your sequencer program and reload them from there whenever you want.
+ The following instructions manual will introduce you to the BEHRINGER VIRTUALIZERPRO
and its various functions. After reading the manual carefully, make sure it is always on hand
for future reference.
1.1 The design concept
The philosophy behind BEHRINGER products guarantees a no-compromise circuit design and employs the best
choice of components. Top-quality 24-bit AD/DA converters which belong to the best components
available owing to its outstanding specifications and excellent sonic characteristics. Two 24-bit DSPs are used
as the heart of the VIRTUALIZERPRO. These perform the precise calculations needed for the processing of the
complex algorithms. Additionally, the VIRTUALIZERPRO uses high quality resistors and capacitors with very
tight tolerances, high-grade switches, low-noise operational amplifiers as well other selected components.
The VIRTUALIZERPRO DSP1024P uses SMD technology (Surface Mounted Device). These subminiature
components known from aerospace technology allow for an extreme packing density, plus the units reliability
could be improved. Additionally, the unit is manufactured in compliance with a ISO9000 certified management
system.

1.2 Before you begin
Your BEHRINGER VIRTUALIZERPRO was carefully packed in the factory and the packaging was 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 in transit.
+ If the unit is damaged, please do not return it to us, but notify your dealer and the shipping
company immediately, otherwise claims for damage or replacement may not be granted.
Shipping claims must be made by the consignee.
The BEHRINGER VIRTUALIZERPRO fits into one standard 19" rack unit of space (1 3/4"). Please allow at
least an additional 4" depth for the connectors on the back panel.
Be sure that there is enough space around the unit for cooling and please do not place the VIRTUALIZERPRO
on high temperature devices such as power amplifiers etc. to avoid overheating.
+ Before you connect your VIRTUALIZERPRO to the mains, please make sure that your local
voltage matches the voltage required by the unit.
The mains connection of the VIRTUALIZERPRO is made by using a mains cable and a standard IEC
receptacle. It meets all of the international safety certification requirements. Please make sure that all units
have a proper ground connection.
+ Please make sure that all units have a proper ground connection. For your own safety, do not
remove the ground connection within the units or at the supply, or fail to make this connection
at all.
+ Please ensure that only qualified persons install and operate the VIRTUALIZERPRO. During
installation and operation the user must have sufficient electrical contact to earth. Electrostatic charges might affect the operation of the VIRTUALIZERPRO!
See chapter 5 INSTALLATION for further details.
As a standard the audio inputs and outputs on the BEHRINGER VIRTUALIZERPRO are fully balanced. If
possible, connect the unit to other devices in a balanced configuration to allow for maximum interference
immunity. The automatic servo function detects unbalanced connections and compensates the level difference
automatically (6 dB correction).
The MIDI links (IN/OUT/THRU) are made over standardized DIN patch cords. The data communication is
isolated from ground by opto-couplers.

Use the ENGINER key to select the right audio channel (similar to : ENGINEL). If you wish to
process the left and right audio channels simultaneously (couple mode), press both ENGINE keys
together. In couple mode both ENGINE LEDs light up. Whenever you edit one of the two audio
channels and then switch to couple mode, the parameters of the active channel will be copied to the
other; i.e if you press ENGINE L before R, left will be copied to right. When parameters cannot be
adjusted separately in a specific algorithm, the DSP1024P switches to couple mode automatically.
9
In each preset you can edit at least two parameters in addition to the preset variation. Use the EDITA
key to select the first parameter. The exact parameter assignment can be seen from the parameter list
printed on top of the unit.
10
The EDITB key allows you to modify the second parameter as required.
11
To give your programs the finishing touch, the VIRTUALIZERPRO incorporates two filters. Use the
EQ HI key to raise or lower the high-frequency portions of the effect program.
12
The EQ LO key activates a filter which processes the low-frequency portions of your preset.
13
The IN/OUT key enables you to bypass the DSP1024P. The green LED lights up as soon as the
VIRTUALIZERPRO is activated. Depending on the Mix mode adjusted (see below), this key can also be
used to activate the Mute function. Additionally, the green LED starts flashing whenever MIDI data are
being received.
14
Use the STORE key to save the edited program to a user preset as shown in the display. 100 user
presets are available on the DSP1024P. Press the key once, select a memory location (number) with
the JOG WHEEL, then press the key again to store the preset.
15
Use the POWER switch to switch the VIRTUALIZERPRO on or off.
Key combinations
To protect the DSP1024P against user errors, three important edit commands have been implemented as a
series of key combinations. For example, in normal operating modes, the presets cannot be reset to their
factory defaults, so as to secure your own programs as safely as possible. Please proceed as follows to
reinitialize the preset default settings:
s Keep the keys EFFECT and STORE pressed before powering up the VIRTUALIZERPRO. Then switch
on the DSP1024P and keep the two keys pressed for about two seconds. The program numbers are
counted up and reset to their original default settings.
The VIRTUALIZERPRO provides two methods to mix the input and the effect signals (External Mix and Internal
Mix modes). Select External Mix mode to use the DSP1024P with a mixing console: in this mode all presets
are set to 100% effect intensity, i.e. you can use the aux return busses of your console to add the processed
signal to the original signal. In External Mix mode the IN/OUT key is used to bypass the unit. Heres how to
enter External Mix mode:
s With the unit switched on, press the Mix mode key combination, i.e. the keys EQ LO and EQ HI. The
VIRTUALIZERPRO enters Mix mode. When the display shows two dashes, the DSP1024P is in External
Mix mode, and when a figure is displayed, Internal Mix mode is selected. To toggle between the two
modes, simply press both EQ keys for about 2 seconds.
In Internal Mix mode you can use the jog wheel to freely select the effect intensity in each preset within a range
from 0% to 100%, a highly useful feature, for instance, to insert the DSP1024P in the effect loop of a guitar
amp. Good results can be achieved with settings between 20% and 50%.
Another key combination can be used to enter MIDI mode. With the VIRTUALIZERPRO switched on, proceed
as follows:
s Keep the keys IN/OUT and STORE pressed for about two seconds, the DSP1024P automatically enters
MIDI mode. Use the IN/OUT key to step through the various MIDI parameters. Press any other key to quit
MIDI mode.
