1. INTRODUCTION
WiththeBEHRINGER VIRTUALIZER PROyouhave purchasedavery powerful multi-effectsprocessorwhich
offersbothfirst-class reverbsoundsand various othereffectalgorithms. Althoughyouwill find ahighnumber of
effecttypes – 32newly developedeffecttypes withmore than 700variations –the VIRTUALIZER PRO canbe
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
acousticsalgorithms whichallow for computingall roomand reverbparameters withabsolute pro-level quality
anda highlynatural sound character.
Despite extensive computing work which is done in the DSP1024P by a “dual-engine” 24-bit processor, the
VIRTUALIZER PROcan be operated easily andconveniently. All parameteredits areperformed with thejog
wheel(rotary control).100 presets are available tostore user-definedprograms.
However, the DSP1024P is by no means limited to excellent reverb and delay programs. In addition to the
simulationof classicplate reverbs, the VIRTUALIZER PRO givesyou extraordinarymodulation effects (such
aschorus andflanger), plusa fewspecial-purpose variants,e.g. amusical pitchshifter aswell as tremolo and
rotaryspeakersimulations. Withthevocoder andvocaldistortion effect programs,you even haveultra-modern
effectsavailable thatthe DSP1024Pgenerates withabsolute 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 canfine-tune thesound of yourpresets tomatch any givenroom characteristics
–atime saving featureespeciallyfor live applications,whereevery secondcounts.Additionally,the DSP1024P
offersdelaytimes ofup to 5.1seconds instereomode. Notonlywill theVIRTUALIZER PROconvince youwith
its logical and easy-to-operate user interface, its technical features, too, are quite impressive. The following
criteriaensure thepro-level processingof audiosignals:
VExtremelylow-noise andhigh-precision 24-bitAD/DA converters.
VAprofessional samplingrate of46 kHz ensures a highsignal resolutionwith afrequency responseranging
from 20 Hz to 20 kHz.
VThe24-bitprocessor features twosections(dual-engine software),eachprocessing one independentaudio
channel.
VLikeall BEHRINGER products,the DSP1024Puses only high-gradecomponents and circuitry.
With its complete MIDI implementation the DSP1024P can be integrated in any MIDI system. Our free
VIRTUALIZER design MIDI software editor (available at www.behringer.com) enables you to program the
VIRTUALIZER PROfrom your personalcomputer, andthe MIDI interfaceallows fortransmitting datafromthe
DSP1024Pand store themon anexternal storage medium.For example, you can usesys-ex dumps tosend
allpresets andsettings to your sequencer programand reloadthem from there whenever youwant.

After power-up, the LED DISPLAY shows the number of the preset last used. This clearly legible, 2½
digit numeric display has plus/minus indicators to show that parameters are being incremented or
decrementedin Editmode.
Fig. 1.3: Function keys and jog wheel
4
With the JOG WHEEL, a continuous rotary control, you can freely edit the selected parameters. Turn
thewheel clockwiseto increasethe values,or counterclockwiseto reducethem.As longas noneof the
edit functions to the right of the JOG WHEEL have been selected, you can use the wheel to select a
program directly, which is shown by a dot lit up in the DISPLAY. While this dot is on, you can select a
programthoughits settingswillnot take immediateeffect.When theJOGWHEEL hasnotbeen touched
for at least one second, the LED in the DISPLAY disappears and the program will be loaded.
5
Use the EFFECT key to directly select one of the 32 basic effect algorithms with the jog wheel.
Whenever a new algorithm is selected, all parameters are reset to default values. See table
6.4 in the appendix.
6
The VARIATION key allows you to select an alternative variation of each effect algorithm activating a
different setup of the numerous internal effect parameters. With this feature you can extensively
manipulatethe effectsound withina verywide range.
7
Use the ENGINE L key to select the left audio channel for true-stereo effects. Many effects may have
different ENGINE L and ENGINE R parameters available through EDIT A and EDIT B. Where to find
which parameter can be seen from the parameter list printed on the top of the unit.
1. INTRODUCTION

VIRTUALIZERPRODSP1024P
8
Use the ENGINE R key to select the right audio channel (similar to : ENGINE L). 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 EDIT A
keyto select thefirst parameter.The exact parameterassignment can be seen fromthe parameter list
printed on top of the unit.
10
The EDIT B key allows you to modify the second parameter as required.
11
To give your programs the finishing touch, the VIRTUALIZER PRO incorporates two filters. Use the
EQHI key toraise or lower the high-frequencyportions of theeffect program.
12
The EQLO key activates afilter which processesthe 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
VIRTUALIZER PROisactivated. Depending ontheMix modeadjusted(seebelow), thiskeycanalso be
usedto activate theMute function. Additionally, the greenLED starts flashingwhenever MIDI data are
beingreceived.
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 POWERswitch toswitch the VIRTUALIZER PRO onor 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:
VKeep the keysEFFECT and STOREpressed before powering up the VIRTUALIZER PRO.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.
TheVIRTUALIZER PROprovidestwomethods tomixtheinputand theeffectsignals(ExternalMixand 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. Here’s how to
enter External Mix mode:
VWith the unit switched on, press the Mix mode key combination, i.e. the keys EQ LO and EQ HI. The
VIRTUALIZER PROenters Mix mode. When thedisplay shows two dashes, theDSP1024P 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.
InInternal Mix modeyou canuse thejog wheel tofreely selectthe effectintensityin eachpreset withina 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%.
Anotherkeycombination canbeused toenter MIDI mode.With the VIRTUALIZER PROswitched on, proceed
asfollows:
VKeep the keys IN/OUT and STORE pressed for about two seconds, the DSP1024P automatically enters
MIDImode. Use theIN/OUT key to step throughthe various MIDIparameters. Press anyother key to quit
MIDImode.

use the enclosed mains cable to connect the unit to the mains power supply.
Please note that not all appliances can be used with different mains voltage ratings. Please
check the description on the back of the unit and the box.
1.4 The effect algorithms
Ina digitaleffects device alleffect programsare basedon algorithms computedby aDigital SignalProcessor
(DSP). How does this work? A DSP can perform an enormous number of binary computations in a minimum
amountof time.The binarycomputations usedto generate an effect aspart ofa programare determinedby a
so-calledalgorithm whichrepresents arule forcomputing numericalvalues thatare exactlyspecified foreach
effect type. For example, reverb algorithms differ from chorus algorithms in their programming. Plainly
speaking:eacheffect isbasedon aspecificalgorithm whichprocessesthe inputsignal(converted fromanalog
to digital before). All of this work is done by the DSP. Once the effect has been generated and added to the
input signal, the digital music signal is converted back to analog by means of a D/A converter.
The VIRTUALIZER PRO permits the change of as many as five parameters which influence the sound in
different ways. This means that for some algorithms the parameters are chosen by using key combinations
with ENGINE L and ENGINE R. In thesecases a combinationof ENGINE L and ENGINE R with theEDIT A
and EDIT B key will not mean that only one channel is affected. The combination EDIT A – ENGINE L is a
different parameter than the combination EDIT A – ENGINE R, these parameters will be changed on both
channels.With areverb effect (likePRG 1)EDIT B – ENGINE R doesnot meanthat theright audio channelis
processed, but that the second EDIT B parameter (with PRG 1: High Multiply) is adjusted.
Theonly exceptionis the DUAL MONO (PARALLEL)effects, whichproduce another effect in theleft channel
fromthe rightchannel.
Inthose casesEDIT B – ENGINE L orEDIT B – ENGINE R meansthat you selectEDIT B and theleft orright
engine.If we only state EDIT B for instance then theselection of theleft or right enginesdoes not playa role.

VIRTUALIZERPRODSP1024P
1.4.1 Reverb and delay algorithms
Cathedral:Reverbprogram thatgenerates long and dense reverberation, much like the natural reverb
ambience found in churches or cathedrals. Particularly suitable for solo instruments and voices.
VARIATION modifies the decay time, EDIT A adjusts the differences between tiled and angular walls
(diffusion), while EDIT B – ENGINE L governs the early reflections and EDIT B – ENGINE R the
brillianceof thereverbsignal.
Plate: The sound of early reverb plates. The decay time can be set from 0-9 s using VARIATION.
EDIT Adetermines the pre-delayby changingthe perceivedsize ofthe room, EDIT Buses ENGINE L
toenhance thestereo imageand ENGINE R to modifythe room brilliance. A classicreverb programfor
drumsand solovoices.
Small Hall: Simulation of a small, highly reverberating hall. Use short reverb times (VARIATION) to
process drum instruments or medium reverb times to enhance wind instruments. EDIT A controls
diffusion,EDIT B early reflections (ENG. L) andstereo width(ENG. R).
Room:Youcan clearlyhear thewallsof thisroom astheyare reflectingthe sound.Theircharacteristics
can be changed with EDIT B from reflective (tiles, marble) to absorbent (carpets, curtains). Use
VARIATION (reverb time / room size) to create any room type – from small store rooms to large living
rooms. EDIT A governs the pre-delay. A useful program for reverb that isn’t directly noticable (rap,
hiphop vocals) or to makedry recordings ofinstruments soundnatural again. Veryall-round effect.
Studio: Middle to large rooms that can be modified in their wall characteristics (EDIT B – ENG. R),
early reflections (EDIT B – ENG. L), position of sound source (= pre-delay: EDIT A) and size
(VARIATION).Creates a naturaland multipurposesound.
Concert: Use VARIATION (reverb time) to create a small theater or large concert hall, determine the
distance to the stage (= predelay: EDIT A), the distance to neighboring walls (= early reflections:
EDIT B – ENG. L)andtheir structure(= diffusion:EDIT B – ENG. R).
Stage: Wonderful reverb, for example, to provide keyboard pads or acoustic guitars with width and
depth (EDIT B – ENG. R = stereo width), and to make them sound fresher (EDIT B – ENG. L =
brilliance). Additionally, you can set the reverb time with VARIATION and the diffusion with EDIT A.
Designedfor liveapplicationsand mixdown.
Vocal:Rich and dense reverbwith middle reverb times (VARIATION) givingsolo voices theirfinishing
touch.EDIT A controls pre-delay, EDIT B – ENG.Learlyreflections and EDIT B – ENG. Rbrilliance.
Percussion: This dense reverb is characterized by pronounced early reflections which make it very
suitable for dynamic signals (drums, percussion, slap bass, etc.). Apart from diffusion (EDIT A) and
reverbtime (VARIATION)youcan createinterestingeffects usingthe separatelyadjustabledecay time
ofhigh-frequency portions(EDIT B), whichmake thereverb more,or lessaudible.
Stereo Delay: Here, the input signal is delayed by as much as 5.1 s. Use VARIATION for a rough
setting from 0 ms to 5.1 s. Use EDIT A to adjust the delay time in milliseconds (in steps of 5 ms up to
VARIATION6, then10 ms).EDIT B determines theamount ofeffect signalthat isfed backto theeffect
(input signal is repeated several times with decaying intensity). The maximum feedback is limited to
avoid feedback loops. Please take a look at table 6.2 for further details.
Stereo Ping-Pong Echo: Much like the delay effect, echo repeats the input signal with decaying
intensity. However, here the echoes lose brilliance with each repetition, which simulates the trendy
“vintage”effectproduced bytapeecho unitsthatwere widelyusedin thepre-digitalera. Additionally,the
“reflections” are alternatingly routed to the left and right channels so as to produce a kind of stereo
effect. The delay times can be set similarly to effect #10 (see table 6.2 in the appendix).
GatedReverb:Phil Collins’song“In theAirTonight” madethiseffect famous:areverb iscut off abruptly
after a certain time. VARIATION determines the cutoff time, EDIT A controls the reverb intensity and
EDIT Bthethreshold abovewhich reverbcomes in (akind ofnoise-gate beforethe reverb signalinput).
If used for rhythmical signals (snare) adjust the length so that the reverb is cut off just before
the next quarter note (e.g. bpm = 120, quarter note = 0.5 s, length less than 0.5 s).
1. INTRODUCTION

VIRTUALIZERPRODSP1024P
Reverse Reverb:Areverb programwith aninverted amplitudeenvelope,i.e. theeffect startssoftly and
thenincreasesin volume.Thiseffect usedto be createdby playingatape inreversedirection, recording
thereverbsignal, and thenplayingback thetapeinforward directionagain,withthe resultthatthe reverb
signal was played back before the actual input signal. VARIATION controls the length of the signal,
EDIT A the delay, and EDIT Bthe threshold above whichthe effectresponds.
1.4.2 Special effects
Vocal Distortion: A clearly up-to-date program for lo-fi effects applied to vocals or drum loops,
combined with a delay. VARIATION determines the degree of distortion in 32 steps, EDIT A controls
the delay of the left channel from 0 to 630 ms. The right channel is coupled to the left one and can be
delayed in the time domain from 0 through 420 ms. EDIT B governs the delay mix. As a little extra the
distortioncircuit alsoincludes an LFO-controlled notch filterwhich audiblywanders backand forth with
maximumdistortion (VARIATION24and higher).
Rotary Speaker: Simulation of the legendary rotary speaker effect produced by speakers rotating at
slow/fast speed within a bulky cabinet. The effect uses the physical principle known as Doppler effect.
VARIATIONchangesthe frequencyresponse(higher value=less highfrequencies).Settings of24and
higher also simulate the tube distortion that was produced by the original cabinets in the 70’s. EDIT A
controlsthe speedof the horn-loaded speaker (treblerange), EDIT B that ofthe rotor(bass range).
Vocoder:Anotherall timefavoritethat hasgainednew popularityduring the discomusic renaissance of
thepastfew years(“Aroundthe World”byDaft Punkor“California” byTuPac).Basically, acontrolsignal
(usually vocals) in the right channel is used to modulate another signal in the left (e.g. synth sound),
which sounds as if the synth was talking (robot voice). VARIATION determines the type of vocoder,
EDIT A the degree of distortion,and EDIT B theeffect sensitivity.
1.4.3 Modulation and pitch shifter effects
Pitch:This effect transposes the input signal eitherin cents (EDIT A – producing a light detune effect)
or semi-tones (EDIT B – up/down to one octave). Settings can be made independently for both
channels,so asto createharmonies orsimply towiden thesound ofa singlevoice. Thepitch effectcan
also be used to produce a cartoon character type voice effect.
Flanger: An LFO constantly modulates the effect signal’s pitch by a few cents up and down. The LFO
speedis controlledby VARIATION,the amountof pitch modulation by EDIT A,the portion of theeffect
signal fed back to the effect block (= feedback) can be determined with EDIT B. By the way, you can
separatelycontrol thechannels’ modulation depthand feedback,which allows for highly complex
modulations. Flanger effects are primarily used for guitars, but there are also lots of other useful
applications: voices, cymbals, bass, remixes, etc.
Chorus:Thoughsimilar totheflanger,chorus usesadelay functioninsteadof feedback. Combinedwith
the pitch shifting feature, the delay produces a very pleasant detune effect. VARIATION changes the
modulationfrequency, EDIT A controls the delayand EDIT B themodulation depth.Chorus effects are
usedso oftenand insuch avariety ofapplications thatany recommendationwould meana limitation of
their use.
1.4.4 Effect algorithm combinations (multi-effects programs)
Effect algorithms nos. 20 through 24 are multi-effects algorithms combining various effect types with, for
instance, a reverb algorithm, and can hence be used simultaneously. For example, effect #24 allows you to
chorus a lead guitar sound and at the same time add some room reverb. (See figure 2.1 “Serial effect
combinations”.)

Tremolo & Delay: Since trip hop has become trendy, this effect – originally found in guitar amps – is
usedtoproduce a moreorless fast andintensivevariation ofvolume(withan additionalpanoramaeffect
included in the DSP1024P). The modulation speed is controlled with VARIATION, the intensity with
EDIT A –ENGINE L,and thepanning rhythmwith EDIT B –ENGINE L. This algorithmbelongs tothe
groupofmulti-effects programs andiscombined withadelay. Delay timeisset withEDIT A –ENGINE R
rangingfrom 0 to 630ms (10 ms increments) feedback is setwith EDIT B –ENGINE R.
Delay & Reverb: Probably the most popular combination used for vocals, solo guitars, etc. With
ENGINE Lyoucanadjustdelaytime(EDIT A –ENGINE L)andfeedback(EDIT B –ENGINE L).EDIT A –
ENGINE Rcontrolsdecay timeand EDIT B –ENGINE R reverb mix. Theprogram usesa BrightRoom
reverbwhich can be used fora variety ofapplications. VARIATION changes theDelay Mix.
Pitch & Reverb:Use ENGINE L to transpose the pitchshifter (EDIT A = cents;EDIT B =semi-tones),
and ENGINE R to control the reverb (Bright Room): ENG. R –EDIT A controls the reverb time,
ENG. R –EDIT B controls themix amount.
Flanger & Reverb: The flanger can be controlled in its modulation depth (ENG. L –EDIT A) and
feedback(ENG. L –EDIT B),thereverbinits decaytime(ENG. R –EDIT A)and mixamount(ENG. R –
EDIT B).You can also adjust themodulation frequencywith the VARIATIONparameter.
Chorus & Reverb: This algorithm combines the popular chorus effect. Controllable parameters:
modulationfrequency(VARIATION),modulationdelay(ENG. L –EDIT A)and depth (ENG. L –EDIT B)
withthe reverb fromprograms nos.21-23.
1.4.5 Dual-mode effects algorithms
Unlike multi-effects programs, dual-mode programs (nos. 25 through 32) have their effects split up and sent
separatelytothetwoaudiochannels(left/right).Forexample,youcanrouteaflangertotheVIRTUALIZER PRO’s
left channel, while using a reverb (effect #26) for the right channel. In this way, you can use the DSP1024P’s
dual-engineprocessor asif it were two separatemono effectsdevices.
Pitch/Reverb: Here, you have a pitch shifter in the left channel (= ENGINE L) with the usual edit
options, and a reverb in the right channel, which can be controlled in its length (EDIT A) and high-
frequencycontent(EDIT B).
Flanger/Reverb: left channel = flanger, modulation speed is controlled by VARIATION, delay by
ENG. L –EDIT Aanddepth by ENG. L –EDIT B. Rightchannel= reverb,withreverbtime controlledby
ENG. R –EDIT A and brilliance withENG. R –EDIT B.
Chorus/Reverb:Leftchannel=chorus,modulationspeediscontrolledbyVARIATION,delayby ENG. L –

ENG. R –EDIT A and brilliance withENG. R –EDIT B.
Tremolo/Reverb: Left channel = tremolo, modulation speed is controlled by VARIATION, delay by
ENG. L –EDIT A and feedback by ENG. L –EDIT B. Right channel = reverb, with reverb time

2.2 Selecting presets
TheVIRTUALIZER PRO stores100 user-definablepresets. Afterpower-up, the unit automatically recallsthe
preset last used. To select another preset, use the JOG WHEEL to enter the preset number of your choice.
Turn the wheel clockwise to increment the preset number, or counterclockwise to decrement it.
Please note that the VIRTUALIZER PRO generally activates the newly selected presets only
after about one second, which is indicated by a dot in the lower right corner of the display. After
2. OPERATION

15
VIRTUALIZERPRODSP1024P
loading the data, the VIRTUALIZER PRO enables the preset and the dot disappears. This brief
interruption avoids the direct activation of every preset, as you scroll through the preset list
with the JOG WHEEL. Otherwise incomplete “parameter remnants” of presets could reach the
audio outputs of the VIRTUALIZER PRO, with possibly disastrous consequences, especially
when using a high-power P.A. system. Thus, the VIRTUALIZER PRO makes sure that no
“unwanted” programs are loaded unintentionally. Additionally, you can rotate the JOG WHEEL
at high speed and still have the time to specifically select the preset of your choice, instead of
any of its “neighbours”.
The effect algorithms may have greatly varying output levels, reduce the sensitivity (input
gain) of subsequent devices before changing programs.
2.3 Editing programs
Editing programs is easy on the VIRTUALIZER PRO. Basically, all essential parameters can be selected
directly via the keypad and edited with the JOG WHEEL. The list to the left of the DISPLAY summarizes the
effectalgorithms thatthe VIRTUALIZER PROcan generate.Just pressthe EFFECT key to recallthese basic
algorithms and directly select them with the JOG WHEEL. With the VARIATION key you can modify the
selectedeffect infull detail,because each variationdoes notonly compriseone parameterbut aset ofseveral
parameters. Thus, you can use the various variations to tailor the sound of an effects program to suit your
specificneeds. The EDIT Aand B keys enable you to edit essentialsingle parameters ofthe selected effects
program, while the EQ LO and EQ HI keys allow for adapting your own presets to match specific room
acousticsor soundpreferences.
Use the ENGINE L andENGINE R keysto editthe leftor rightaudio channelsettings. Ofcourse, you canedit
bothchannels atthe sametime in couplemode. Whenentering couplemode, theVIRTUALIZER PRO copies
theparameter settings ofthe channellast activated tothe otherchannel, sothatboth ofthem haveanidentical
set of parameter values. Finally, you can also save the changes made to the preset.
2.4 Saving programs
Use the STORE key to save an edited preset. Basically, all parameter changes can be saved. Whenever
you’re editing a preset, the DISPLAY starts flashing to indicate that the edits will be saved only when you
confirm them by pressing the STORE key twice. Example:
VYou recall a program for editing. Then you edit the preset as desired using the function keys and the jog
wheel. During this process, the flashing STORE key reminds you that the preset settings have been
changedbut not saved yet. Pressthe STORE key once. Thedisplay readsthe current presetnumber and
starts flashing. To keep the original preset, use the jog wheel to select another preset that can be
overwritten.Pressthe STOREkeyagain to savethechanges totheselected preset.Ifyou wish tooverwrite
the original preset, simply press the STORE key twice (after editing) to save all changes you have made.
Whenever you have edited a preset and pressed the STORE key twice, all previous settings in
this preset are erased and overwritten with the new parameter values. However, if you wish to
keep the original preset, use the JOG WHEEL to select another preset before you press the
STORE key a second time.
2.5 MIDI control
Use the MIDI key combination to select the MIDI parameters you wish to adjust. For this purpose, keep the
IN/OUT and the STORE keys pressed for about two seconds. All parameters can be edited with the JOG
WHEELand thesetwo keys.The MIDImenu includessix pageswhich you can select by pressing the IN/OUT
key(upwards) andtheSTORE key(downward).
On the first page you can select the MIDI channel. The DISPLAY shows a small “c” (= channel). The JOG
WHEEL adjusts a channel from 1 through 16. To switch off the MIDI function, simply select the “0” value
(displayedas“-”).
Onthe secondpage you can select MIDIOmni mode,i.e. theunit transmits/receives onall 16MIDI channels.
The DISPLAY reads “O”(= Omni).Use theJOG WHEELtoactivate (“1”) ordeactivate (“0”)Omni mode.
2. OPERATION

16
VIRTUALIZERPRODSP1024P
The third page allows for configuring controller commands. On its right-hand side, the DISPLAY shows a
capital“C” (= Controller). The JOGWHEEL selects one of thefollowing four controller modes:
Dis
p
la
y
Mode
0No controller data are transmitted.
1Controller data are received but not transmitted.
2Controller data are transmitted but not received.
3Controller data are transmitted and received.
Tab. 2.1: Controller settings
Forfurther details seetable 6.4 in section 6 “APPENDIX”.
The fourth page gives you access to the program change setup. The DISPLAY shows a capital “P”
(= Program). Here, too, four modes can be selected with the JOG WHEEL, as follows:
Dis
p
la
y
Modus
0Program Changes are not transmitted.
1Program Changes are received but not transmitted.
2Program Changes are transmitted but not received.
3Program Changes are transmitted and received.
Tab. 2.2: Program change settings
Thefifthpage oftheMIDI menushowsthe “storeenable”flag representedbya capital“S”in theDISPLAY. The
value“0” disablesthe reception of controller #28,and thereforeprotects theuser presetsfrom being modified
viaMIDI. Accordingly,the value“1” enables MIDIcontroller #28so thatyou canmodify orreplace presetswith
aremote MIDIdevice or asequencer. Inthis casethe actual settingswill bestored directlyto the locationthat
correspondsto thecontroller value.
Attention! Since the “store enable” mode allows you to access memory locations directly via
MIDI, it is possible that stored presets will be replaced or altered if controller #28 messages are
sent on the same MIDI channel. The purpose of this mode is to facilitate MIDI backup and
restore operations without express confirmation at the VIRTUALIZER PRO. It is therefore
recommended to disable (flag = 0) this mode as soon as the intended data transfer has ended.
This is done automatically when you switch off the VIRTUALIZER PRO.
On the sixth and last page, you can access the “System Exclusive” functions. This is indicated by a “d” (for
dump) in the DISPLAY. To the left of this “d” a number is displayed:
- “0” means that no SYSEX data will be sent or accepted.
- “1”will enable theVIRTUALIZER PROto receivedata. When STORE is pressedthe unitwill wait for data,
this is shown by flashing dots (LEDs) in the DISPLAY. The MIDI key LED flashes signaling that SYSEX
datais beingreceived.
- “2”willenable the VIRTUALIZERPROtosend a“bulkdump”.Start yourMIDIsequenzerprogram and press
STORE on the DSP1024P to start the transmission.
To load these settings again, select 1, press STORE and start your MIDI sequenzer program.
During a bulk dump, all audio functions of the VIRTUALIZER PRO will be deactivated.
If you press the IN/OUT key again on the sixth page, the VIRTUALIZER PRO quits MIDI setup mode. At all
times you can press any other key to leave the MIDI setup directly.
The full-featured MIDI implementation of the VIRTUALIZER PRO allows for easily integrating of the
VIRTUALIZER PROinto any MIDIsystem.
VMIDIIN
Any MIDI data sent to the VIRTUALIZER PRO (sequenzer, MIDI footswitch, etc.) is received via the MIDI IN
jack. For example, when you wish to use the VIRTUALIZER PRO as an effects devices for your guitar rack,
you can connect the MIDI IN jack to a MIDI footswitch that allows for selecting program presets. If your rack
includesanother MIDI effectsdevices (e.g. amulti-effects processor), thedata sent from the MIDI footswitch

VMIDITHRU
TheMIDI THRU jack is usedto loop through incoming MIDIdata, i.e. anycontrol datareceived at theMIDI IN
ofthe VIRTUALIZER PROcan betransmitted viathe MIDI THRU jack toother MIDIdevices/instruments.

3. APPLICATIONS
The BEHRINGER VIRTUALIZER PRO is a highly flexible device that can be used for a wide variety of
applications.Priorto a presentationofthe VIRTUALIZER PRO’smanyuses,please notethefollowing remarks
on how to set signal levels correctly.
3.1 Level setting
Take care to set all levels properly on the VIRTUALIZER PRO! Low levels deteriorate the dynamics of the
musicsignal, whichresults ina poor,weak andnoisy sound. On the otherhand, excesslevels overdrivingthe
convertersintheVIRTUALIZER PRO should alsobeavoided.Digital distortionis(unlikeitsanalog counterpart)
very unpleasant to hear as it does not occur gradually but abruptly.
Usetheinput levelmeter of theVIRTUALIZER PRO toadjustthe inputsignal,so thattheClip LEDflickers only
rarely.Make sure thatit never lights up permanently!
3.2 Using the VIRTUALIZER PRO in the aux bus
By using the VIRTUALIZER PRO in an aux bus of your mixing console you can feed the channel signals of
one,several or evenall consolechannels into theVIRTUALIZER PRO, i.e. for each channelyou can usethe
auxbussesto separatelydeterminethe reverblevels of, forinstance, variousdrumsounds: whilelotsof reverb
is applied to the snare drum, the effect intensity could be reduced in the channels assigned to the tom-toms.
To use the VIRTUALIZER PRO in the aux bus, the unit must be wired as follows:
Fig. 3.1: Wiring aux busses
3. APPLICATIONS

18
VIRTUALIZERPRODSP1024P
Connect the two Input phone jacks with the Aux Send outputs of the mixing console, and the Output jacks of
the VIRTUALIZER PRO with the Aux Return inputs of the console. If you want to use the BEHRINGER
VIRTUALIZER PROin monoor dual mode,connect oneaudio channel (left or right)to oneaux bus.
Turn down the volume on your amplifier to protect your equipment against damage. All
devices you wish to interconnect should remain switched off until they are wired correctly.
Let’ssuppose you wish touse the VIRTUALIZER PRO ina live application, interfacedwith the F.O.H. mixer,
to enhance the guitar sound with a subtle chorus effect.
Connect the VIRTUALIZER PRO to the aux bus of your mixing console (fig. 3.1). Connect the units to the
mains and adjust the operating level(s) if necessary. Switch on the VIRTUALIZER PRO and set the levels
appropriately (see 3.1). Press the Mix combination to make sure that the unit is set to Mix External mode.
Press the EFFECT key and use the JOG WHEEL to select and thus activate the chorus effect (#19). Slowly
turnup theaux buslevel untilthe effectportion addedto theguitar signalsuits yourneeds. Subsequently,you
can make all necessary fine-adjustments. We assume that you wish to edit the modulation frequency of the
chorus effect: press the VARIATION key and set the modulation frequency with the JOG WHEEL. To set the
modulationdelay, pressthe EDIT Akey. Themodulation depthof thechorus effectcan beset bypressing the
EDIT Bkey. Having edited all parameters as desired, you can save the changes to the original (or anyother)
preset.
3.3 Using the VIRTUALIZER PRO in the insert path
Basically,you canalso insertthe VIRTUALIZER PROin achannel orsubgroup ofyour mixingconsole. Usea
dedicated insert cable. Inserting the VIRTUALIZER PRO in a single channel will be useful only if you wish to
process a specific signal (e.g. vocals) with the VIRTUALIZER PRO, or if any other insert facilities of your
mixing console are already in use.
Fig. 3.2: Wiring the VIRTUALIZER PRO in the insert path
With certain special effects, for example the “Vocoder” effect, it is even more useful to insert the
VIRTUALIZER PRO in a specific channel rather than connecting it to the aux bus. Proceed as follows: the
signal from which you are going to generate the vocoder sound is routed to the left audio channel
(e.g. keyboard sound), while the right audio channel can be used to control and modify this sound. Use a
dedicatedinsert cableto connectthe leftaudio channelwith achannel inserton yourmixing console(fig. 3.2).
Connectthe signalsource to beprocessed withthe vocodereffect (e.g.keyboard) tothe normalchannel input
(XLR/jack). Connect the right audio channel of the VIRTUALIZER PRO with a controller (e.g. a microphone
channeldirect out). Talk intothe microphone to controlthe keyboard sound with your voice, i.e.anything you
sing or talk into the microphone is reproduced together with the keyboard sound.

3.4 Using the VIRTUALIZER PRO as an effects device for instruments
With its extensive MIDI implementation the VIRTUALIZER PRO can also be used, for instance, as a multi-
effects device in a guitar rack. Of course, you can connect it up in both stereo and mono. The following hints
illustratethe VIRTUALIZER PRO’s versatility ifused witha guitar amp.
Fig.3.3: Connectingthe VIRTUALIZER PRO to a guitaramp (send/return-mono)
Basically, the VIRTUALIZER PRO should be inserted between the preamp and the power stage. Almost all
guitaramps havean insertor effect loop to sendthe preampsignal ofthe guitar amp to theaudio inputsof the
VIRTUALIZER PRO. The VIRTUALIZER PRO processes the preamp signal and sends it back via the guitar
amp’s return bus (power amp in), from where it is routed to the power stage. When you use a stereo rack
system for amplification, you can wire the VIRTUALIZER PRO in stereo. Connect the preamp to the audio
inputsofthe VIRTUALIZER PRO,and theaudiooutputs (left/right)toone channeleach ofthepower amp(left/
right).
Since most guitar amps only have a serial insert loop, you should make sure that the
VIRTUALIZER PRO is set to Mix Internal mode. In this mode you can control the effect intensity
applied to the guitar signal. However, if your amp features a parallel effect loop which allows
for adding the effect-signal portion (similar to an aux path in a mixing console), we recommend
that you use the VIRTUALIZER PRO’s Mix External mode. In this case, the effect intensity
present at the output of the VIRTUALIZER PRO is 100%, and you can use the effect loop to
determine the amount of effect added to the guitar signal.
Instrumentalists can benefit from a variety of advantages offered by the VIRTUALIZER PRO‘s MIDI
implementation. For example, you can use a MIDI footswitch board, e.g. the BEHRINGER MIDI FOOT
CONTROLLERFCB1010, to send program changecommands viaMIDI. Connect theMIDI OUTjack of your
MIDI board to the MIDI IN jack on the VIRTUALIZER PRO. If the VIRTUALIZER PRO fails to respond to the
program change commands sent from the MIDI board, check the MIDI channel settings. Consult the user’s
manualof yourMIDI boardto findout on which channels program change commandsare transmitted(usually
inOmnimode).SettheMIDIchannels appropriately inMIDImode(see2.5)andenable the VIRTUALIZER PRO
toreceive program changecommands.
IfyourMIDIboard allowsyoutotransmit MIDI controllerdata,youcan evenchangeparametersettings via MIDI
whileplaying. For instance,you can freelychange the effectintensity from 0- 100% whileplaying (Contr. 27,
Value 0 - 100). Set the controller for Mix-Internal mode (Contr. 30, Value 0) so that it can be used to increase
the effect intensity. In this way, guitar solos can be enhanced with chorus and delay effects, while the effect
intensityis graduallyreduced whenplaying rhythm.You can even control thefunction ofthe IN/OUTswitch to
bypass the VIRTUALIZER PRO when an unprocessed signal is needed. Basically, all MIDI devices that are
capable of transmitting MIDI controller commands, e.g. keyboards/sequenzers, will allow for using these
features.
3. APPLICATIONS

VIRTUALIZERPRODSP1024P
The VIRTUALIZER PRO may also be inserted between the outputs of a keyboard and the inputs of a mixing
console.If required, adjustthe levelswith the OPERATINGLEVEL switch.
3.5 Using the VIRTUALIZER PRO in a MIDI system
Withitsbuilt-in MIDIinterfacethe VIRTUALIZER PROcanbe integratedinto any MIDIsystem. It transmitsand
receivesboth program changeand controllerchange informationtoperform programchanges viaMIDIfrom a
sequenzeror anyother MIDIdevice. Wireand setup theVIRTUALIZER PRO asshown below:
Fig.3.4:Connecting theVIRTUALIZER PROvia MIDI toasequencer/computer andakeyboard (optional)
3.6 Saving data via MIDI
TheVIRTUALIZERPRO’s MIDIimplementationalso allowsforarchiving oneor several presetson an external
storagemedium. Proceedas follows:
Connect the MIDI OUT jack of the VIRTUALIZER PRO to the MIDI IN jack of a MIDI data recorder (e.g.
sequenzer). Press the STORE and IN/OUT keys simultaneously to enter MIDI mode. Set program change
modeto “0” andcontroller changemodeto “3”.Now quitMIDImode bypressing theSTOREkey. Usethe JOG
WHEEL to select the preset whose data you wish to save. When the preset is activated its parameters are
transmittedas controller data and canbe recorded on a sequenzeror similar device.Repeat thisroutine until
all presets of your choice have been sent to the external data recorder.
To load archived data back into the VIRTUALIZER PRO, you must enable controller reception in MIDI mode
(see 2.5). Then, start the sequenzer to automatically transmit each preset data set back to the
VIRTUALIZER PRO. Press the STORE key, select a program location to store the data and then press the
STOREkey again.If youwant toautomate MIDIstore functionsyou mustenable thestore mode,to switchon
the reception of controller #28. This allows you to directly store any modifications of the actual preset on the
preset number that is transmitted with the controller. You can also restore a complete preset that has
previouslybeen recordedwith aMIDI sequenzer on the samelocation ithad before.
To store all presets at once, you can use a very special form of MIDI communication: system-exclusive data,
i.e. the VIRTUALIZER PRO informs the sequenzer or MIDI file recorder about its make and device type, and
transmitsall parameter settings of allits presets.To activate thishighly usefulfunction, please enterthe MIDI
modeby simultaneously pressingthe IN/OUTandSTORE buttons.Then, select the“dump” modeby pressing
theIN/OUTbutton fivetimes. Now, theDISPLAYshouldread asmall “d”. Thestatus indicators“0”or “1”inform
you that the sys-ex function is disabled or enabled respectively. If the function is on, the DSP1024P is ready
toreceive system-exclusive data from yourMIDI sequenzer orsimilar device.If you wishto storethe settings
chosen, use the JOG WHEEL to select the status indicator “2”; now your VIRTUALIZER PRO is ready to
transmit its own system-exclusive data. Select a track on your MIDI sequenzer, set it to record-ready mode,
start the recording and finally press the STORE button on your DSP1024P.
