1. Introduction

The Rocktron Intellifex®LTD is a 24-bit digital effects processor utilizing three

individual 16-bit converters and Sigma-Delta A/D conversion, achieving a 64x

oversampling rate and better than 100dB dynamic range. The Intellifex LTD is totally

programmable and allows for complete MIDI control. The unit features pitch shifting,

8 voice stereo chorusing effects, digital delay effects including 2-tap, stereo and ping

ponging effects, unsurpassed digital reverb quality and highly flexible configuration

programming allowing for simultaneous operation of up to 5 effects plus complete

mixing capabilities. The unit also offers Hush Systems first fully digital implementa-

tion of patented HUSH®noise reduction at the units input, along with delay and

reverb ducking capabilities.

For a thorough explanation of the Intellifex®LTD and its functions, please read

this manual carefully and keep it for future reference. A better understanding of how

the Intellifex®LTD operates will help make designing your own preset sounds much

easier.

After removing the Intellifex®LTD from the box, save all packing materials in

case it becomes necessary to ship the unit.

WHAT MAKES THE INTELLIFEX

LTD 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 chorus ever.

* High quality 4 voice pitch shifting over 3 full octaves.

* 2-voice pitch shifting or 4-voice chorusing offered simultaneously with Hush®, Delay and

Reverb.

* Programming via knobs instead of push buttons.

* Easy to read, wide viewing angle display.

1. Introduction

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 LTD will display "STORED"

briefly before displaying the new preset number/title.

RECALLING A STORED INTELLIFEX LTD PRESET

STEP 1 To recall a stored Intellifex LTD 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

CHANGING PRESET 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 LTD 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 LTD 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 LTD 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

LTD flashes "STORED" at least once before exiting the preset to ensure

that the desired modifications were stored into memory.

3. Front Panel

Some of the controls on the Intellifex®LTD 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) RECALL button:

This button is used to recall the displayed preset.

(3)PRESETcontrol:

The function of this control is dependent on the CONFIG button (located to the right

of the PRESET control).

When the CONFIG LED is off, turning the PRESET control will cause the Intellifex

LTD 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 CONFIG LED is on, the PRESET control is again used to scroll through

the successive presets, but instead of displaying preset titles the Intellifex LTD will

display the effect configuration stored for each preset.

(4) CONFIG button:

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 LED above the CONFIG button is lit when the configuration

is displayed.

(5) DISPLAY panel:

The DISPLAY panel consists of 16 characters. Each character consists of 14

segments.

(6) COMPARE button:

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.)

3. Front Panel

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) PARAMETER ADJUST 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) STORE button:

This button is used to store values into the Intellifex LTD 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) FUNCTION SELECT control:

This control allows access to each function of the Intellifex LTD. 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) BYPASS button:

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 LTD. The gain can be adjusted from -12dB to +12dB. Use the INPUT

LEVEL 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) OUTPUT LEVEL 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 LTD be used for

best results. If connecting the Intellifex LTD to a high sensitivity input, such as the

input to a guitar amp, the -10 setting should be used.

4. Rear Panel

(1) RIGHT CHANNEL INPUT jack:

This standard 1/4" mono jack provides input to the right channel of the Intellifex

LTD. When using only one input (mono), this jack should be used.

(2) LEFT CHANNEL INPUT jack:

This standard 1/4" mono jack provides input to the left channel of the Intellifex

LTD. When using only one input, this jack should not be used.

(3) RIGHT CHANNEL OUTPUT jack:

This standard 1/4" mono jack provides an output for the right channel of the

Intellifex LTD. When using the unit in a mono application, either output jack may

be used.

(4) LEFT CHANNEL OUTPUT jack:

This standard 1/4" mono jack provides output for the left channel of the Intellifex

LTD. 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.

(7) 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 LTD, 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

LTD. 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.

(8) MIDI IN lack:

This 7-pin DIN connector receives MIDI information from the device which is

transmitting the MIDI commands for the Intellifex LTD to execute.

4. Rear Panel

(9) 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 when performing a memory dump.

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.

(10) 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.
