What makes the Intellifex Online Unique?
 Super quiet operation due to use of digital HUSH®and high quality 16-bit converters.
 High purity sound due to the use of a 64X oversampling A/D converter, which
samples the signal 64 times as often as a conventional converter, and also due to
the use of a separate dual D/A converter. Most "bargain" digital effects units use a
single converter multiplexed 3 ways, for decidedly higher distortion and lower
dynamic range.
 24-Bit processing and memory circuits to maintain maximum dynamic range.
 Ability to store up to 8 unique MIDI controller patches with each preset.
 Very high quality effects algorithms.
 Highly stereo effects with panning available on almost all signals.
 8 voice chorusing with an enormous number of parameters for the richest sounding
chorus ever.
 High quality 4 voice pitch shifting over 3 full octaves.
 2-voice pitch shifting or 4-voice chorusing offered simultaneously withHUSH,
delay and reverb.
 Programming via knobs instead of push buttons.
 Easy to read, wide viewing angle display.

2. Quick Setup
STEP 3 Now press the STORE button a second time to store the modified
values into the selected preset location. The Intellifex Online will display
"STORED" briefly before displaying the new preset number/title.
Rcalling a Stored Intellifex Online Preset
STEP 1 To recall a stored Intellifex Online preset, first turn the PRESET control
to the desired preset number you wish to recall. The display will alternate
between the preset number/title selected and:
PRESS RECALL FOR
STEP2 To call up the preset you have selected, press the RECALL button. The
display will now show only the new preset number/title.
14 PRESET TITLE
ChangingPreset Parameters
STEP 1 The parameter menu for each effect can be called up via the FUNCTION
SELECT control. Turn this control to the effect to be changed.
**** REVERB ****
STEP 2 Turn the PARAMETER SELECT control to select which parameter select
the parameter to be modified.
REV DECAY 59
STEP 3 Use the PARAMETER ADJUST control to modify the parameter value.
The LED above the STORE button lights to indicate that a parameter
value has been modified from the stored preset.
REV DECAY 32
STEP 4 The COMPARE button may be used to compare the stored value to the
new one.
REV DECAY 59
Storing Modified Parameter Values
STEP 1 To store modified parameter values, press the STORE button while
viewing a parameter or effect title to begin the store procedure. The
Intellifex Online will alternate displaying the current preset number/title
and:
STORE TO PRESET
STEP 2 Turn the PRESET control to select the desired preset number to store
the new parameter values into (if the new values are to be stored into
the current preset location, this step is not necessary). User presets
may be stored in preset locations 1-80. Presets 81-160 are factory
presets and cannot be copied over. The Intellifex Online will now
alternate displaying the new preset number/title and:
STORE TO PRESET
STORED
STEP 4 After the modified parameters have been stored into a new preset
location, the Intellifex Online will display "COPY TITLE TOO?". This
occurs only when a new preset location is selected to store the modified
parameters into, and allows for the title from the original preset to be
copied to the new preset location as well. To copy the title, press the
STORE button a third time. The display will again flash "STORED".
NOTE 1 If it is not desired to copy the title from the original preset, turn either
the PRESET or FUNCTION SELECT control to exit the store procedure.
NOTE 2 If a modified preset is edited without completing the store procedure (i.e.
"STORED" displayed at least one time), all edited parameter values will
be lost and the preset will revert to its original condition the next time it is
recalled. When saving altered parameters, always make sure the
Intellifex Online flashes "STORED" at least once before exiting the
preset to ensure that the desired modifications were stored into
memory.

Some of the controls on the Intellifex Online front panel have more than one function,
dependent upon what mode the unit is currently operating in. Please read this section to become
better aquainted with these functions.
1 POWER switch
2 RECALLbutton:
This button is used to recall the displayed preset.
3 PRESETcontrol:
The function of this control is dependent on the CONFIG button.
When the CONFIGLED isoff, turning the PRESETcontrol will cause the Intellifex Online to
exit its current function. The PRESET control may then be used to scroll through the
successive factory and user presets and titles stored in its memory.
When the CONFIGLED is on,thePRESETcontrol is again used to scroll through the
successive presets, but instead of displaying preset titles the Intellifex Online will display the
effect configuration stored for each preset.
4 CONFIGbutton:
The CONFIG button is used to toggle between displaying either the preset title or the
configuration of the currently displayed preset. The configuration display indicates both
which effects the displayed preset executes and the order in which they are executed. The
LEDabove the CONFIG button is lit when the configuration is displayed.
5 DISPLAY panel:
TheDISPLAY panel is a16 character, vacuum fluorescent display type.
6 COMPAREbutton:
The COMPARE button may be used to compare a modified parameter value to its stored
value. (If comparing an altered value to the stored value and the stored value is currently
being viewed, turning a knob or pressing a button that changes the parameter value
displayed will cancel the previous modified value.)
The COMPARE button may also be used to simultaneously compare multiple modified
parameters under the same effect heading (i.e. Reverb, Mixer, etc.) to the stored values. To do
so, turn to the effect heading where the modified parameters are located and press the
COMPARE button. When the STORE LED is off, the stored parameter values are currently
active. When the STORE LED is lit, the modifed values are active.
If a knob is turned or a button is pressed which changes the effect heading when the stored
parameters are active (STORE LED off), any modified parameter values under that heading
will be lost. This is also true if a MIDI control change is received while the stored parameters
are active.

7 PARAMETERADJUST control:
This control is used to adjust the displayed parameter value. When the parameter is changed
from its original value, the LED above the STORE button will light until either (a) the new
value is stored, (b) a new preset is selected or (c) the parameter is returned to its original
value.
8 STOREbutton:
This button is used to store values into the Intellifex Online memory when modified. See
Chapter 8, section C, "Storing Modified Parameters" for more information.
9 PARAMETERSELECTcontrol:
When monitoring parameter values, this control will scroll through the available parameters
under the current effect heading.
In the "TITLE EDlT" function, this control will scroll through the available characters in the
title that may be edited.
10 FUNCTIONSELECT control:
This control allows access to each function of the Intellifex Online. Depending on which
configuration the current preset is built upon, these functions may include:
Preset Select Reverb Parameters
Mixer Parameters Title Edit
HUSH Parameters MIDI Controller Mapping
Chorus Parameters MIDI Program Mapping
Pitch Shift Parameters MIDI Channel
Delay Parameters Ducker Parameters
Factory Restore MIDI Dump/Load
11 BYPASSbutton:
When pressed, the LED is lit and all effects are bypassed.
12 INPUT LEVEL meter:
These LEDs provide visual indication of the peak level of the input signal. For the optimal
signal-to-noise ratio, it is best to adjust the input level so that the last LED (0dB) is rarely lit.
This will guard against the possibility of overdriving the unit.
13 INPUT LEVEL control:
This control adjusts the unit's gain to match the signal level at the input of the Intellifex
Online.The gain canbe adjusted from-12dB to +12dB.Use the INPUTLEVEL meter to
determine the setting of this control.
14 CLIP L.E.D.:
This L.E.D. is part of the output section and, when lit, indicates that the final analog output is
being overdriven because the Effects Level, Direct level, and Output Level control are set too
high. If this occurs, reduce these levels until this L.E.D. does not light.
15 OUTPUTLEVEL control:
This control is used to adjust the output level of the unit and may be adjusted from zero
signal to a small amount of gain.
16 REFERENCELEVELswitch:
This switch determines the output range of the unit and may be set at either -10dB or +4dB.
When using professional studio equipment providing a nominal input level of +4dB, it is
recommended that the +4 setting on the Intellifex Online be used for best results. If
connecting the Intellifex Online to a high sensitivity input, such as the input to a guitar amp,
the -10 setting should be used.

1 RIGHTCHANNELINPUT jack:
This standard 1/4" mono jack provides input to the right channel of the Intellifex Online.
When using only one input (mono), this jack should be used.
2 LEFTCHANNELINPUT jack:
This standard 1/4" mono jack provides input to the left channel of the Intellifex Online. When
using only one input, this jack should not be used.
3 RIGHTCHANNEL OUTPUT jack:
This standard 1/4" mono jack provides an output for the right channel of the Intellifex Online.
When using the unit in a mono application, either output jack may be used.
4 LEFTCHANNEL OUTPUT jack:
This standard 1/4" mono jack provides output for the left channel of the Intellifex Online.
When using the unit in a mono application, either output jack may be used.
Note: When using a mono input (Right Channel INPUT jack)
and a mono output (either the Left or Right Channel
OUTPUT jack), the left and right effected signals will be
summed at the single output.
5 PHANTOM POWER jack:
This jack offers the ability to power the Rocktron MIDI Mate™Foot Controller from a seven
pin MIDI cable which connects from the MIDI Mate to the MIDI IN jack on the rear panel of
the Intellifex Online, eliminating the need to find an AC outlet near where the footpedal would
be placed during a performance—or the need to run an extension cord out to the MIDI Mate.
Instead of inserting the adaptor into the MIDI Mate POWER jack, plug it into the
PHANTOM POWER jack on the Intellifex Online. This will power the MIDI Mate through
pins 6 and 7 of the MIDI cable connecting the two units. A 7-pin MIDI cable must be used
and is available through your Rocktron dealer.
6 MIDI IN jack:
This 7-pin DIN connector receives MIDI information from the device which is transmitting
the MIDI commands for the Intellifex Online to execute.
4. Rear Panel

6
7 MIDI OUT/THRU jack:
This standard 5-pin DIN connector passes on the MIDI information that is received at the
MIDI IN jack to other MlDI-compatible devices via a MIDI cable. It also outputs MIDI data
whenperforming a memorydump.
Note: Inherently in MIDI there is a limit to the number of devices which can be chained
together (series connected). With more than three devices, a slight distortion of
the MIDI signal can occur (due to signal degradation) which can cause an error
in MIDI signal transmission. Should this problem arise, a MIDI box can be used
which connects directly to the MIDI device which transmits MIDI information and
has multiple connectors for the multiple devices receiving MIDI. MIDI cables
should not exceed 50 feet (15 meters) in length.
8 POWER jack:
This jack accepts power from the 9VAC/1500mA adaptor supplied with the unit. For more
information on the power supply see the Power Requirements section on page 2.

Using the Intellifex Online with a keyboard and a mixer

9
Using the Intellifex Online with a guitar rack system
!! CAUTION !!
Note: For best results when using the Intellifex Online with high gain distortion, always put the Intellifex Online after
the distortion in the signal chain, never before it.
Never connect the outputs of a power amplifier or guitar amplifier to the inputs of the Intellifex Online. This
could damage the Intellifex Online.

10
Caution: Digital Output overload
As the input signal enters at the unit’s input (A), the unaltered direct signal is fed to
the Direct Pre/Post Hush Selector (B). Here you may choose for the direct signal to
remainunaltered(Pre) or feed it through the digital Hush section (E) of theIntellifex
Online (Post). Before being fed to the Hush section, the signal must first be converted
from an analog signal to digital via the converter (D). When the direct signal is fed to
the Hush section, it will remain digital until it is summed together with the output of
theEffectsLevelcontrol(G).
It is important to remember that it is possible to overload the Digital to Analog
Converter (H) if the effects levels and direct signal level are set too high when using
the Hush section with the direct signal. If this occurs, reduce these levels until the
front panel CLIP L.E.D. does not light.
Also note that when passing the direct signal through the digital HUSH (Post), a
stereo signal will be converted to mono.
6. Principle of Operation

MIXER PARAMETERS
Effects Level
(in Hush;Chorus; Delay; Reverb and Hush;PitchShift; Delay; Reverb configurations)
This controls the level of the entire effect signal. This control should be set
relativetothelevelsofthe Left and Right Direct signals. In configurations
whichdonotincludeamaster Effects Level, the single effect level param-
eter(ChorusLevel,DelayLevel,etc.)isconsideredthemasterEffectLevel
control.
Left/Right DirectLevels
These controls allow for the left and right Direct signal levels to be set
individually,therebyallowingforpanningoftheDirectsignaltotheleftor
rightoutput.Thesecontrolsareavailableinallconfigurations.
DirectHush This determines whetherthedirectsignalpassesthroughthedigital HUSH
section of the Intellifex Online or bypasses it. Selecting "Post" will pass the
Direct signal through the HUSH system while selecting "Pre" will bypass
this section. (Note: Selecting "Post" converts a stereo direct signal to
mono.)
Chorus Level, Delay Level, Reverb Level, etc.
InconfigurationswhichincludeaMaster Effects Level control, these control

TheIntellifex Onlineprovidesa RegenerationLimiting feature , whichguards
againstthepossibilityofoverloadingtheprocessorwhenusinghigh
regenerationlevelsinconfigurations where a combination ofmultiplevoices
is panned to the left or right. If the regeneration level is set too high, the
IntellifexOnlinetriggers the Regeneration Limiting and a limit is internally
set for the regeneration. This limit can not be exceeded by increasing the
Regen L or Regen R parametervaluesintheMixersection.
If,for example, in the Hush;Chorus; Delay; Reverb configuration, Voice1
is panned to the left and the Regen L parameter is set to its maximum

B. REVERB SECTION
Reverb,orreverberation,isthecontinuanceofsoundwithinagivenroomor enclosed chamber after the source of the
sound has stopped producing it. More specifically, it is a multitude of echoes so densely spaced that, to the human ear,
seem as a single continuous sound. These echoes gradually decrease in intensity until they are ultimately absorbed by the
boundaries and obstacles within the room or enclosure. As the sound waves from the signal source strike the walls or
boundaries of the room, a portion of the energy is reflected away from the obstacle and another portion is absorbed into it,
thereby causing both the continuance of sound and the decaying or "dying out" of the sound.
REVERB TYPES
TheIntellifexOnline Hush;Reverb configurationoffers8differentreverbtypes: PlateA , Plate
B , Room A , Room B , Hall A , Hall B , Stadium and Dual .
ThePlatereverbtypesimulatesanartificialmethodofproducingreverberation,popular in the
earlyyearsofrecording,whichinvolved using a fairly large, but very thin, metal plate sus-
pended at its four corners by steel wires under tension. This metal plate becomes excited by
adriverunit(similartoadynamic speaker without the diaphragm) and the resulting reverbera-
tion is picked up by contact microphones. The Intellifex Online offers two Plate reverb types
which reflect the most common plate characteristics. This type of reverb is often used on
drumandvocal tracks.

Hall reverbsimulatesthereverberationcharacteristicsofaverylargeroomwithahighceiling.
Reflections in a hall are much longer than a typical room, as the length of time it takes for the
soundwaves to travel from one surface to the nextisgreatly increased.
Stadium reverb simulates the characteristics of a large stadium or arena and should be used
withlargeamountsofpredelay and high frequency damping.
Dual reverb is unique in that it allows for the left and right channels to be processed indepen-
dently one another. For example, the Predelay for the left channel can be set at 100mS while
the Predelay for the right channel can be set at 200mS. This results in reverb output from the
leftchannel100mSbeforereverbisoutputfromtherightchannel.
REVERB PARAMETERS
Reverb Input Thisparameterdetermines whether the input to the Reverb section is active
(passing a signal) or muted (not passing a signal).
Reverb Level Thisparameterdeterminesthelevelofthe reverb signal at the output
relative to the direct signal and any other effect signals. It is accessible
fromboththeMixerfunctionandReverbfunctionparameterlists.

13
Reverb Decay Thisparameterspecifies the length of time that the reverb signal will sound
before it has completely faded out (or until its echoes have been ultimately
absorbedbytheboundarieswithinthegiven "room"). The maximum length
ofthisdecaywillvarydependentuponwhichreverbtypeisactive.

Dir In Pan Thisparameter allows you to panthe direct input signal to thereverb
section to the left or right—allowing for only the left or right channel to be
reverberatedwhenusedwiththe Dual reverb type, or,foronechanneltobe
reverberatedtoagreaterdegree than the other.Thisparameterisadjust-
able from 0 to 100—where "0" is full left, "100" is full right and "50" is
center.
Predelay L This parameter determines the amount of time after a signal is input to the
Intellifex Online that the left channel signal will be input to the reverb.
Delayingthereverbsignal provides greater separationoftheinputand
reverb signals and helps to increase the apparent size of the Room, Hall, or
Stadium.
Predelay R This parameter determines the length of time after a signal is input to the
Intellifex Online that the right channel signal will be input to the reverb.
Gate Gating thereverbsignalclosesdownthedecayofthereverbveryquickly
afteraprescribed amount of time (most commonly a very short period of
time). This effect is often used on drums (particularly snare drums) to
producetheeffect of a much fatter percussive sound. Note that gating on
theIntellifex Online acts on thereverb decay,noton the reverb output ason
many other units.
Gate Decay The Gate Decay parameterdetermineshow quickly the gate will close
downthereverbdecayafterthereverb has sounded for the specified time.
Gate Threshold The Gate Threshold determinesthethreshold point at which gating will take
place. When the signal is below this threshold point for a period of time, the
reverbwillbe gated. When the input signal peak rises above this threshold,
thegatewillopenandreverbwillbeheard.
Hold Time The HoldTime determineshowlongthereverb signal will sound before the
gate begins to close.

14
C. DELAY SECTION
Delay is simply a reproduction of the input signal, originating at a prescribed time (usually expressed in milliseconds, or
mS)followingthe input signal.
DELAY TYPES
TheIntellifexOnlineHUSH;Delay;Duckerconfigurationoffers3delaytypes:Stereo,
Ping-Pongand 2-Tap.
TheStereodelay type provides two separate delays. This delay type is used for applica-
tionsrequiringtwodiscretedelaylineswithindividualregenerationloops.
ThePing-Pong delay type regenerates each delay’s output into the opposite delay’s
input instead of its own. This causes the delayed signals to bounce back and forth from the
leftchanneltotheright(providedthedelayoutputsarepannedleftandright).
The2-Tap delay type provides a single long delay line with two outputs and offers twice
the delay time of the Stereo delay type.
DELAY PARAMETERS
Delay ThisparameterdetermineswhethertheDelay section is active (passing a
signal) or muted (not passing a signal).
Mute Type This parameter allows for muting of the Delay section at its input (Pre), its
output (Post) or both.
Muting the input (Pre) of the delay restricts any signal from entering the
delay section until the delay is switched in. When using a moderate
amount of regeneration, switching out the delay with the input muted will
generateanon-delayedsignal which will play overthedecayingregener-
ated signal which continues on after the delay is switched out.
Muting the output (Post) of the delay results in the delayed signal being
immediately turned off when the delay is switched out. This means that
delays and regeneration will not continue once the delay is switched out. If
the output were not muted, signals input before switching the delay out
wouldbeallowedtoregenerate-evenafterswitchingoutthedelay.
It is also possible to mute both the input and output (Both) so that no
signal enters or exits the Delay section when it is not switched in.
Level 1/2 Theseareindividuallevelcontrolsforeachofthetwodelaysavailablein the
Delaysection.Thesearenotthe same as the Delay Level parameter found
intheMixer function (which adjusts the overall level of both delay signals).

15
Pan 1/2 This allows for the panning of each delay to the left or right output, if
desired.ThePan parameter is adjustable from 0 to 100—where 0 is full left,
100 is full right and 50 is center.
Dly Time 1/2 These parameters determine the amount of time after a signal is input that
the delayed signal will begin to reproduce the input signal.
Regen 1/2 Thisparameterisprovidedfor each delay and determines thenumberof
times the delayed signal will repeat itself. This is achieved by feeding the
delayedoutputbackintotheinput. Higher levels of regeneration will result
inmorerepeats.
D Type The DelayType parameterdetermineswhether the Stereo, Ping-Pong or2-
Tap delay type is currently active.
Dl Hf Damp DelayHighFrequencyDamping determinestheamountof high frequency
contentinthedelayedandregeneratedsignals.Higheramountsofdamping
will result in less high frequency information in the delayed signal.

16
D. DUCKER SECTION
The process of ducking enablestheuser to suppress the level of a given signal or effect dynamically,dependent upon
thepresenceof another signal which is desired to be prominent. The ducking featureoftheIntellifex Online works in conjunc-
tionwiththeDelayandReverb sections to attenuate the delay and/or reverb level while a phrase is being played (resulting in
a less cluttered, more intelligible sound), yet return each to its original level when the phrase ends—thus allowing for the full
decayofthedelayed and/or reverberated signal.
DUCKER PARAMETERS
Ducker In the HUSH;Delay;Ducker configuration,thisparameterdetermines
whetherthe Ducker is off oron.
In the HUSH;Chorus;Delay; Reverb and HUSH;Pitch Shift; Delay; Reverb
configurations,thisparameterdetermineswhethertheDuckeriseither(A)

onboththedelayandreverb.
Sensitivity Thisparameterdeterminesthethresholdpointabove which the ducker will
beginattenuatingthedelayand/orreverbsignal.Untiltheinputsignal
reachesthislevel,thedelay/reverbsignalwillnotbeaffected.
Attenuation Thisparameterdetermineshowmuchthe delayed signal is attenuated
(muted). It may be set for only a slight change in signal level or it can
completelyattenuatethedelay/reverbsignalsothat no delayed or reverber-
ated signal passes while ducking is active.
Release Rate This parameter is adjustable from .2 seconds to 9 full seconds, and
determines the length of time it takes for the muted delay signal to return to
its original signal level after the input signal falls below the threshold point
set by the Sensitivity parameter.

17
E. PITCH CHANGE SECTION
Pitch Change effects involve splitting the input signal into at least two separate signals, then modifying the pitch of one
signal and mixing it back together with the unaltered direct signal. The Intellifex Online offers two types of pitch change
effects: Chorus and Pitch Shift.
CHORUS
TheChoruseffectisachievedbyusingoneormoredelayedsignals,detuningthese
delayed signals (slightly changing their pitch) then modulating this detune effect so that the
amount of pitch detune is constantly varying. Using many delayed signals at different delay
lengths-as well as using different detune amounts, modulation rates and modulation depths
for each delayed signal—results in a rich, spacious stereo chorused signal.
CHORUS PARAMETERS
Level (Individual Voices)
Thisparameteradjuststhevolumeofthedelayedsignalrelativetotheother
voice(s)ofthe effect and is included in the parameter list for each voice(or
eachdelaysignal)ofboththe 8-Voiceand4-VoiceChorus effects. (This
level control is not the same as the Chorus Level found in the Mixer function
parameterlist.)
Pan The Pan parameterallowsyoutopaneachvoice(ordelay)ofthechorused
signal to the left or right channel. This parameter is adjustable from 0 to
100—where 0 is full left, 100 is full right and 50 is center.
Delay The Delay parameterdeterminesthedelaytime(inmilliseconds)foreach
tap of the chorus signal. It is this delayed signal that is detuned and
modulated to produce the chorus effect. Using shorter delay times for this
effectproducesatightersoundingchorusedsignal,whileusinglongerdelay

Depth The Depth parameteradjuststheamountofmodulationofeachdelayed
signal. A lower depth setting will produce a more subtle detune effect while
a higher setting of this control will cause a more drastic detuning of the
delayedsignal.
Rate The Rate parameterdeterminesthesweepspeedforthe delayed signal
(i.e. the speed at which the delayed signal is modulated). Here a low rate
results in a slow speed and a higher rate results in a faster speed.
