Section 1 - Setting Up

Studio Quad V2 User's Manual

SECTION 1 - SETTING UP

UNPACKING THE STUDIO QUAD V2

Your Studio Quad V2 was carefully assembled and packaged at the factory. Before you proceed any further, make sure the
following items are included:

• (1) Owner's manual

• (1) DigiTech Studio Quad V2 Studio Effects Processor

• (1) PS0920 Power Supply

• (4) Rack screws

• (1) DigiTech warranty card

Please save all packaging materials. They were designed to protect the unit from damage during shipping. In the unlike­ly event that the unit requires service, use only the factory supplied carton to return the unit.

SUPPLYING POWER

The Studio Quad V2, like any piece of computer hardware, is sensitive to voltage drops, spikes and surges.
Interference such as lightning or power "brownouts" can seriously, and in extreme cases, permanently damage the
circuitry inside the unit. Always be sure to connect your Studio Quad V2 to well grounded AC outlets. You may
wish to use a Spike/Surge Suppressor or AC LIne Conditioner to further protect your investment.

FRONT PANEL CONTROLS

The layout of the Studio Quad V2's front panel is simple and straightforward. Figure 1-1 shows the various parts of
the Studio Quad V2.

Figure 1-1 Front Panel

1) DISPLAY - The Studio Quad V2's large custom display is where you get most of the information you need to

move around the operating system. The display has several important sections that you need to understand when
you use the Studio Quad V2. They are:

1a) Program Number Indicator - These three large digits in the upper left corner of the display indicate

which Program is currently selected.

1b) Factory / User Indicators - Directly below the Program number are the Factory and User Program indica-

tors. These indicators also include a CHANGED icon to tell you whether the Program has been modified but
not stored in memory. Factory Programs can be modified but must be stored in a User Program location since
Factory Programs cannot be overwritten.

1c) Page Indicators - The bottom left corner of the display is occupied by the Page indicators. They display

the number of Pages available and the Page which is currently selected. These icons only appear in the FX
Edit and Utilities modes.

1d) Information Line - This row of 24 characters (top line of the display) is the Information line. It gives

more detailed information about specific functions and items, and contains things like Program names,
Parameter names, and Utility or auxiliary information.

Section 1 - Setting Up

Studio Quad V2 User's Manual

1e) Parameter Data Sections - There are four Parameter Data sections in the display. They are immediately

below the Information line, and correspond with the <1> through <4> buttons on the front panel. Each
section displays the current value of the indicated Parameter. Each section also has an arrow that shows
which Parameter in the display is selected.

A CC indicator in each group tells whether the indicated Parameter is set up to be continuously controlled
( "continuous control" includes internal LFOs, dynamic modifiers, and MIDI continuous controller data).
Directly below each section is a CHANGED indicator that lights to indicate that the Parameter has been
changed but not stored.

1f) Input Level / Clip Meters - The bottom center of the display is occupied by the Input Level and Clip

meters. These meters show the input level of each channel, and use a peak detector action to display the
highest levels at the inputs. The Clip indicator at the end of each meter shows whether the input signal is
being clipped at the analog input section (pre-digital).

1g) Effect Routing Matrix - The Effect Routing Matrix shows the signal flow of the currently selected

Program. This matrix includes boxes that represent each effect module along with lines that indicate how
those effects are connected to inputs, outputs and each other. If an effect module is bypassed, a line
appears through that module's box in the Matrix.

When in FX Edit mode, the box that represents the currently selected effect module will flash. Likewise the
Modifier module flashes the MODIFIER indicator, the Input Mode module flashes the Input Routing indica­tors and the Output Mode module flashes the Output Routing indicators.

2) PROGRAM BUTTON - Selects Program mode for Program selection. The Data Wheel is used to select a

program for loading. The Program button can also be used to toggle between the User or Factory Program
Banks. The active Program Bank is shown in the display by the Factory / User indicators (see item 1b).

This button is also used to access the Compare mode. See pg. 13 for more information.

3) FX EDIT BUTTON - Selects FX Edit mode for Program modification. If you continue to press this button, you

will scroll through each individual effect module, the Modifiers module and the Input/Output modules.

4) PARAMETER BUTTONS - The Parameter buttons <1> through <4> are used to select the Parameter or

Utility item you want to edit. In Program mode, they can also be used to enter the FX Edit mode's 1st through
4th module.

5) PREV PAGE BUTTON - Scrolls to the previous Page in the Parameter list. Note that the Page indicators

change to reflect the currently selected Page number in the Parameter list.

6) STORE BUTTON - The <STORE> button is used to store user Programs in memory for later recall.

7) NEXT PAGE BUTTON - Scrolls to the next Page in the Parameter list. Note that the Page indicators change

to reflect the currently selected Page number in the Parameter list.

8) UTILITY - Selects the Utility mode where global functions such as Screen Contrast, MIDI Channel, Program

Maps, SysEx Channel, SysEx Dumps, Program AutoLoad and Reset can be accessed.

9) IN LEVELS - This button is used to access both the automatic and manual input leveling controls. For more on setting

input levels, see pg. 29.

10) BYPASS - Bypasses all the effects in the Studio Quad V2.

11) DATA WHEEL - The Data Wheel lets you scroll through Programs and change Parameters values.

REAR PANEL CONNECTIONS

The layout of the Studio Quad V2's simple and straightforward rear panel is illustrated in Figure 1-2.

Figure 1-2 Rear Panel

1) AUDIO INPUTS - These four 1/4” inputs can be used for several different combinations of input configura-

tions. The Input Configuration module of each Program defines how each Input is used. See pg. 11 for more info.

2) AUDIO OUTPUTS - The Studio Quad V2's outputs can also be configured in many different ways. These set­tings are found in the Output Configuration module of each Program. See pg. 11 for more info.

3) OUTPUT LEVEL SWITCH - Selects whether the signal is nominally output at line level (-10 dB) or at profes­sional level (+4).

4) MIDI IN - MIDI data is received at this port. When MIDI data is received, the MIDI indicator in the display flash­es on and off.

5) MIDI OUT / THRU - Merges MIDI data generated by the Studio Quad V2 with MIDI data received at the input.
Please see pg. 31 for more information.

6) FOOTSWITCH - This jack allows connection of the DigiTech FS300 3-button footswitch or any shorting-type
footswitch. If using the DigiTech FS300, button 1 increments through Programs, button 2 decrements through
Programs, and button 3 bypasses the Studio Quad V2's effects. When using any other single momentary switch
device, the switch acts as a Bypass.

NOTE: The footswitch must be plugged in on power up in order for the Studio Quad V2 to detect which type

of switch is being used.

7) POWER INPUT - Connect the included power supply to this jack. It is a 4-pin DIN connector. Use only the
DigiTech PS0920 power supply with the Studio Quad V2.

Because of its flexibility, the Studio Quad V2 can be connected in several different ways to meet the requirements of
specific applications. The following diagrams offer some ways the Studio Quad V2 can be connected.

IN LINE

The Studio Quad V2 can be connected between a line level instrument output (such as keyboards, recording decks,
etc.) and a line level input (such as mixing console inputs). This method is called the "in-line" method because the
Studio Quad V2 is connected directly in the audio path of the source. When you use the in-line method, the master
wet-to-dry effects mix is controlled from the Studio Quad V2 operating system. Cable routings for this method look
like Figure 1-3:

WARNING: Make sure the Studio Quad V2's audio levels are all down before changing the setting of this switch.
Also, be sure you know which setting is best for your particular equipment setup, as setting this switch to +4 can
overload the inputs of some line-level equipment. DigiTech is not responsible for any
damage to speakers or components due to misuse of this switch.

EFFECTS LOOP

This application uses the Studio Quad V2 in an effects loop of a mixing console. In this application, the source is
routed directly to the mixer channel input(s). From there, the Studio Quad V2 gets its source audio from the con­sole's auxiliary send, and mix levels are controlled directly from the console. Figure 1-4 shows a common recording
studio or live sound reinforcement setup for effects processing with a console.

Figure 1-4 Effects Loop Configuration

Figure 1-5 shows an example of a typical stereo effect setup as seen from the console, and shows how to handle
both true stereo and mono input signals using two auxiliary sends.

This is the method of choice in many recording applications because of the impressive realism and depth of texture
that it produces. While it is slightly more complicated to set up and requires twice as many auxiliary sends, stereo
effects (particularly reverbs) improve dramatically in imaging and spaciousness.

Section 1 - Setting Up

Studio Quad V2 User's Manual

REMEMBER: When you use this method to process stereo sources such as keyboards, the auxiliary sends on

your console should be set up exactly opposite one another, as shown on channels 1 and 2 of Figure 1-5. Note
that the left channel is sent to Aux 1, while the right channel is sent to Aux 2. When using mono sources like
vocals and bass guitar, send equal levels from both Aux 1 and Aux 2 to maintain proper soundfield balance of
the effects, as shown on channels 5 and 8.

PARALLEL EFFECTS

Another application for the Studio Quad V2 allows you to independently process four discrete signals simultaneous­ly. This method also utilizes the effects loops of your console, and since each effect has a mono input, the auxiliary
sends can be set up in a much more straightforward way. Figure 1-6 shows how to connect the Studio Quad V2 for
this application.

Figure 1-6 Quad Mono Input / Dual Stereo Output Configuration

Using this method, you could use channel 1 for a long vocal reverb, channel 2 for a short gated snare drum reverb,
channel 3 for lead guitar delay, and channel 4 to thicken keyboard instruments with a detuner. This method also
offers the flexibility of running different channels in-line or in an effects loop.

REMEMBER: Outputs can be configured any way you like, so don't let any of this input / output stuff scare

you.

A WORD ABOUT BYPASS

Because of its flexibility, the Studio Quad V2 can be connected in several different ways to meet the requirements of
many specific applications. However, the definition of Bypass may change, depending on the application. The Studio
Quad V2 features Application Specific Bypassing so that the Studio Quad V2 functions appropriately in nearly every
application. When Bypassed, the Studio Quad V2 simply switches the Effects in that Program OFF, but the Dry
Levels defined in that Program remain untouched. If the effects are all wet (no Dry Level), the Bypass function effec­tively Mutes the Studio Quad V2. If the Dry Level is up, then the Studio Quad V2 passes the original signals through
without processing. A line through the modules in a Effect Configuration Matrix indicate that the module is
Bypassed.

SECTION 2 - BASIC FUNCTIONS OF THE STUDIO QUAD V2

GETTING AROUND THE OPERATING SYSTEM

The menu structure of the Studio Quad V2 has been specially designed to be easy to use. The display shows the
information you need, but to make things even easier for you, illumination of the front panel buttons offers addition­al operating information.

The front panel buttons give you information in one of two ways:

1) If the button is DIMLY lit, its function is INACTIVE. Pressing a dimly lit button causes it to light brightly and
its function becomes the active item in the display. If the DIMLY lit button doesn’t light after you press it,
the button is unavailable.

2) If the button is BRIGHTLY lit, its function is ACTIVE. Pressing an active button (other than the
<PROGRAM> button) reselects the already active item in the display.

PROGRAM MODE - Program mode allows you to scroll through the Factory and User Programs using the Data
Wheel. When the Studio Quad V2 is turned on, it sets itself to Program mode. Program mode is active when the
<PROGRAM> button is lit and a Program name is present on the Information line (top line) of the display. You can
toggle between Factory or User Programs by pressing the <PROGRAM> button when it is lit. The FACTORY PRG
or USER PRG indicator will be displayed according to which bank is selected. In this mode, all other buttons on the
front panel are dim or off.

To select a Program, do the following:

• Make sure Program mode is selected. If the <PROGRAM> button is dim, press <PROGRAM> once to return

to Program mode.

• Use the <PROGRAM> button to select the Program bank (Factory or User). Each successive press of the

<PROGRAM> button toggles between the Factory and User bank of Programs.

• Using the Data wheel, scroll to the Program you want to hear.

The selected program is immediately autoloaded. The AutoLoad feature can be turned off, allowing you to view a
program before actually loading it. See pg. 33 for further details.

FX EDIT MODE - This mode allows you to edit:

1) FX Modules,

2) the Modifier Module,

3) the Input Mode Module, and

4) the Output Mode Module of your Programs.

Use the <FX Edit> button to enter the FX Edit mode and then to select the next module for editing.

HINT: If you look at the Effect Routing Matrix while you press the FX Edit button, the currently selected mod­ule will flash. The Studio Quad V2 uses Pages to navigate within an effect. A Page is a group of up to four effect
Parameters that appear on the screen at one time. To move through the Pages in a Program, use the <NEXT
PAGE> and <PREV PAGE> buttons. Note that as you scroll through the Pages, the Page indicator in the lower
left corner of the display changes to show the currently displayed Page.

SELECTING FX TYPES AND DEFAULTS

The Studio Quad V2 has made custom digital signal processing easier than ever by giving you access to a complete
library of professionally developed effects settings. Page one of every FX Module allows you to:

1) Bypass that effect module

2) Select an effect Type (Chorus, Reverb, Delay, etc.)

3) Select a Default for the selected effect Type

Section 2 - Basic Function of the Studio Quad V2

Studio Quad V2 User's Manual

9

The Default parameter allows you to select one of several effect settings stored in the Studio Quad V2's library. For
example, there are 8 Dual Delay defaults to choose from. All Factory Programs use these Default settings. So, if you
like the Delay that is being used in Factory Program 62, simply locate page one of the FX Module, then use the <4>
button and the Data Wheel to recall the default (which happens to be A1-Pingpong1) in your new program. This
eliminates the need to copy all those parameters from one location to the other. It also gives you several starting
places so you can get as close as possible to the custom sound you are trying to create. Once you edit one of the
parameters in the FX Module, the default name is replaced with the word "Custom". This means that a default set­ting has been customized by the user or changed by real-time Modifiers for that program.

NOTE: There are two Banks available for the defaults, Bank A and Bank B. Effects stored in bank A contain the dry

signal for typical in-line applications. Effects in bank B do not contain the dry signal, and boosts the effect
level so it can be used with a mixing console's effect loops . EQ, Panner, Noise Gate, and Tremolo do not
contain Dry level controls and therefore do not have a bank B available.

MODIFYING FX MODULE PARAMETERS EXAMPLE

Let's modify an effect Parameter. Factory Program 139 uses a quad delay with a delay time of 700 milliseconds. The
tap percentages are set to DlyA = 25%, Dly B =50%, Dly C =75%, and Dly D =100%, which gives you evenly spaced
delay taps. But suppose they're too slow to fit the tempo of a piece of music you're composing. With most effects
units, you'd have to recalculate each delay tap individually, but the Studio Quad V2 makes it simple:

• If you're not already there, switch to Program mode and use the Data wheel to scroll to Factory Program 139.
The display reads:

• Press <FXEDIT>. Note the current module being edited is flashing in the Effect Routing Matrix. The display
reads:

• Press <NEXTPAGE> twice. Position 2 of the Information line shows that the current delay time setting is 700
milliseconds. Remember that the total delay time shown in the display is divided among the delay taps in the
Module. The display reads:

• Use the Data Wheel to decrease the delay time. Both the Store button illuminates and the CHANGED icons
turn on indicating that the Program has been modified.

• Press the <Program> button to return to Program Mode, or continue in Edit Mode by continuing to press the
<FX EDIT> button.

NOTE: Make sure you store any changes you want to save before exiting the edit mode. See pg. 13 for more infor-

mation.

EFFECT & INPUT / OUTPUT CONFIGURATIONS

The Studio Quad V2's ability to accommodate a number of different input and output routing configurations makes it
an extremely useful and flexible tool for many different applications.

Programs 101 through 112 in the Factory Program bank are all the FX module configurations available in the Studio
Quad V2. For diagrams of these 12 Effect Configurations, see pg. 38. When you find one that you like, you can save
it to a new User Program location for later use.

NOTE: Choosing an Effect Configuration does not define the input / output routing schemes or the actual effects

used within the configuration. This means that even one configuration can be used thousands of different
ways.

To select a new Effect Configuration, do the following:

• Scroll through Factory Programs 101 - 112 until you find a configuration you want to use. Let’s use Pgm. 101;
the display looks like this:

Next, select the input/output configuration you want to use:

• Press the FX Edit button 6 times. The input section of the Effect Routing Matrix begins flashing and the infor­mation line reads:

Input Mode: Quad Mono

• Use the Data Wheel to scroll through the 9 available input configurations.

• Press the FX Edit button one more time. The output section of the Effect Routing Matrix begins flashing and
the the information line reads:

Output Mode: Quad Mono

• Press parameter button <1>, then use the Data Wheel to scroll through the 9 available output configurations.

• Press parameter button <4>, then use the Data Wheel to to set the output level for the program.

NOTE: Make sure you store any changes you want to save before exiting the edit mode. See pg.13 for more

information.

USING MODIFIERS

Modifiers are unique tools that can be used to dramatically alter your sound based on information from signal amplitude,
the settings of a Low Frequency Oscillator (LFO) or MIDI Continuous Controller information.

Every Program in the Studio Quad V2 has a set of Modifiers. Up to 8 Modifier links can be assigned to control para­meters. There are three types of Modifiers that can be linked to a parameter: MIDI CCs, LFOs, and Dynamic (signal
level dependent).

MIDI CCs - When you use MIDI CCs, the Studio Quad V2 responds to CC numbers 0-127 and CHP (channel
pressure or aftertouch). This means that you could assign your keyboard's modulation or pitch bend wheel (or any
other MIDI CC device) to control effect Parameters.

For example, you can have a synth's modulation wheel (usually MIDI CC#1) control the in level of a reverb and cho­rus in one program while the delay feedback is controlled in another.

Section 2 - Basic Function of the Studio Quad V2

Studio Quad V2 User's Manual

LFOs - When you use LFOs, Parameter values can be controlled automatically between a defined minimum and

maximum setting at a rate set by the user. The Studio Quad V2 has 2 user definable LFOs in each program that can
be assigned to any Parameter.

For example, you can create an auto panner without using an auto panner module. Simply link an effect's output pan
parameter to the LFO modifier and the LFO will move that parameter back and forth. This modifier can be a very
useful weapon in the ongoing battle of new sound creation. There are two LFOs available in each program that can
use unique speeds and waveforms.

Dynamic Modifiers - When you use Dynamic Modifiers, the Parameter values are controlled in relation to the
dynamics of the input signal. The possibilities are nearly endless, and they cannot be duplicated using any other
method.

For example, you could link the Dynamic Modifier of a Program to control a chorus level. It doesn't sound like much
on paper, but imagine the expressiveness of this type of effect on a vocal part. As the dynamics of the music
increase, the chorus becomes less apparent. Ease up on the vocal a little and the chorus increases. ALL IN REAL
TIME!

NOTE: Linking a Modifier to a Parameter causes the Parameter to change as if you were changing it using the Data

Wheel. The only difference is that the <Store> button and PROGRAM CHANGED indicators do not light.
Therefore, the Default name may display 'Custom' if a Parameter is consistently being changed by a
Modifier. Storing the Program will store these new Parameter values.

LINKING A PARAMETER TO A MODIFIER

To link a Parameter to a Modifier, do the following:

• Press <FX EDIT> until you readh the Modifiers Edit Mode. The display looks something like:

Notice that the modifiers icon in the bottom right corner of the display begins flashing.

• Pressing the <NEXTPAGE> and <PREVPAGE> keys will scroll through Pages 1-8 to select which of the 8
Modifier Links you want to use.

• Use the Data wheel to scroll to the Parameter you want assigned to Modifier link #1. As you scroll, the MIN
and MAX values for each Parameter show in the display.

NOTE: The MUTE and THRUeffect types do not have any Parameters to connect to, so they will not appear

in the parameter list.

• Press <3> to select the Minimum Value Parameter.

• Use the Data wheel to set the minimum Parameter to the value you want when the controller is in the mini­mum position. These values vary because different Parameters have different value units, such as milliseconds
or percent.

• Press <4> to select the Maximum Value Parameter.

• Use the Data wheel to set the maximum Parameter to the value you want when the controller is in the maxi­mum position.
