SECTION 1 - SETTING UP

UNPACKING THE STUDIO QUAD

Your Studio Quad 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 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, 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. Here are a few tips that will help

you get the best possible performance out of your Studio Quad while

avoiding damage:

• Always make sure you have a "clean" power source for connect-

ing to the Studio Quad. This means that the AC power line you

connect to the Studio Quad should be as free from voltage fluc-

tuations and RF interference as possible. In recording environ-

ments, "clean" power is also important in preventing AC hum or

buzz from getting to tape.

• Use a good quality spike / surge suppressor . This is an inexpen-

sive solution to all but the most severe AC line conditions. A

good quality power strip can save you a lot of money in repair

bills because they prevent large spikes and surges from reach-

ing your equipment racks. Also in this category (but more expen-

sive) are rackmount power conditioners. Some of these, like the

DigiTech PLM-82, have retractable light tubes and RF filtering.

• Always make sure that your audio lines are as far as possible

from power cables. This will further prevent noise, hum, and

stray magnetic fields from entering your signal path. If audio and

power lines must run close to each other, try to avoid running

them parallel to one another.

Use only high-quality audio cables to connect devices to and

from the Studio Quad. Although they're more expensive, they

sound better, last longer, and are much less likely to pick up or

induce noise, interference, hum, or buzz into your system.

FRONT PANEL CONTROLS

(Video) Digitech Studio Quad four Rack effects processor demo

The layout of the Studio Quad's front panel is simple and straightfor-

ward. Figure 1-1 shows the various parts of the Studio Quad.

Figure 1-1 Front Panel

1) DISPLAY - The Studio Quad'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. They are:

1a) Program Number Indicator - These three large digits in the

upper left corner of the display indicate which Program is cur-

rently selected.

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

are the Factory and User Program indicators. 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 informa-

tion about specific functions and items, and contains things

like Program names, Parameter names, and Utility or auxiliary

information.

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>, <2>, <3>, and

<4> buttons on the front panel. Each section displays the cur-

rent value of the indicated Parameter. Each section also has

an arrow that shows which Parameter in the display is select-

ed.

Section 1 - Setting Up

Studio Quad Owner's Manual

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 controlller 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 indi-

cator 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 flashes Input

Routing indicators and the Output Mode module flashes the

Output Routing indicators.

2) PROGRAM BUTTON - Selects Program mode for Program selec-

tion. 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 in conjunction with the FX Edit button to

access the Compare mode. See pg. 16 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.

This button is also used in conjunction with the Program button to

access the Compare mode. See pg. 16 for more information.

4) PARAMETER BUTTONS - The Parameter buttons (buttons 1-4) 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, 2nd, 3rd, or 4th module.

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 man-

ual input leveling controls. For more on setting input levels, see pg. 32.

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

11) DATA WHEEL - The Data Wheel lets you scroll through Programs

and change Parameters values.

REAR PANEL CONNECTIONS

The layout of the Studio Quad's simple and straightforward rear panel

is illustrated in Figure 1-2.

Figure 1-2 Rear Panel

1) AUDIO INPUTS - These four inputs can be used for several differ-

ent combinations of input configurations. The Input Configuration

module of each Program defines how each Input is used. See

pg. 12 for more info.

2) AUDIO OUTPUTS - The Studio Quad's outputs can also be config-

ured in many different ways. These settings are found in the Output

Configuration module of each Program. See pg. 12 for more info.

3) OUTPUT LEVEL SWITCH - Selects whether the signal is nominally

output at line level (-10 dB) or at professional level (+4).

WARNING: Make sure the Studio Quad's power switch is off before chang-

ing 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.

received, the MIDI indicator in the display flashes on and off.

5) MIDI OUT / THRU - Merges MIDI data generated by the Studio

Quad with MIDI data received at the input.

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's effects. Using any other single momentary switch device,

the switch acts as a Bypass.

Note: The footswitch must be plugged in on power up order for the

Studio Quad 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.

MAKING CONNECTIONS

Because of its flexibility, the Studio Quad can be connected in several

different ways to meet the requirements of specific applications. The fol-

lowing diagrams offer some ways the Studio Quad can be connected.

IN LINE: The Studio Quad 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 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 oper-

ating system. Cable routings for this method look like Figure 1-3:

EFFECTS LOOP: This application uses the Studio Quad 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

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 pro-

cessing 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 dramati-

cally in imaging and spaciousness.

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

allows you to independently process four discrete signals simultane-

ously. 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 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 gui-

tar 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 can be connected in several

different ways to meet the requirements of many specific applications.

However, the definition of Bypass may change in these different appli-

cations. The Studio Quad features Application Specific Bypassing so

that the Studio Quad functions appropriately in nearly every applica-

tions. When Bypassed, the Studio Quad 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 func-

tion effectively Mutes the Studio Quad. If the Dry Level is up, then the

Studio Quad passes the original signals through without processing.

Remember that the lines through the modules in the Effect

Configuration Matrix indicate that the modules are Bypassed.

SECTION 2 - BASIC FUNCTIONS OF THE STUDIO QUAD

GETTING AROUND THE OPERATING SYSTEM

The menu structure of the Studio Quad 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 in 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) rese-

lects 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 is turned on, it sets itself to Program mode. Program mode is

active when the <PROGRAM> button is bright 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> but-

ton when it is brightly lit. The FACTORY PRG or USER PRG indicator

will light in the display 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> but-

ton 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 fea-

ture can be turned off, allowing you to view a program before actually

loading it. See pg. 37 for further details.

FX EDIT MODE - This mode allows you to edit FX Modules, the

Modifier Module, the Input Mode Module, and 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. A helpful

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 uses

Pages to navigate within an effect. A Page is a group of up to four

Section 2 - Basic Function of the Studio Quad

Studio Quad Owner's Manual

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 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

The Default parameter allows you to select one of several effect set-

tings stored in the Studio Quad's library. For example, there are 10

Dual Chorus defaults to choose from. All Factory Programs use these

Default settings. So, if you like the Chorus that is being used in

Factory Program 69, simply use the <4> button and the Data Wheel to

recall the default (which happens to be A2-Shallow) in your new pro-

gram. 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 or changed by real-time

Modifiers for that program.

NOTE: There are two Banks available for the defaults, Bank A and

Bank B. Bank A contains the dry signal for typical in-line applications.

Bank B does 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 there-

fore do not have a bank B available.

MODIFYING FX MODULE PARAMETERS EXAMPLE

Let's modify an effect Parameter. Factory Program 40 uses a quad

delay with a delay time of 500 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 makes it simple.

Here's how to change the tempo of the delays:

• If you're not already there, switch to Program mode and use the

Data wheel to scroll to Factory Program 40. The display reads:

• Press <FX EDIT>. Note: the current module being edited is

flashing in the Effect Routing Matrix. The display reads:

• Press <NEXT PAGE> twice. Position 2 of the Information line

shows that the current delay time setting is 500 milliseconds.

Remember that the total delay time shown in the display is divid-

ed among the delay taps in the Module. The display reads:

• Use the Data Wheel to decrease the delay time. Both that the

Store button illuminates and the CHANGED icons turn on indi-

cating that the Program has been modified.

• Press the <Program> button to return to Program Mode, or con-

tinue in Edit Mode by continuing to press the <FX EDIT> button.

Note: Make sure you store the settings after you have made any

changes. See pg. 16 for more information.

EFFECT & INPUT / OUTPUT CONFIGURATIONS

The Studio Quad'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 1 through 12 in the Factory Program bank represent all the

FX module configurations available in the Studio Quad. For diagrams

of these 12 Effect Configurations, see pg. 41. When you find one that

you like, you can save it in a new User Program location for later use.

Remember that 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 1 - 12 until you find a configu-

ration you want to use. The display looks something like this:

Once you have selected an Effect Configuration, you can select the

input/output configuration you will be using.

•Press the FX Edit button until 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 available input configu-

rations.

• Press the FX Edit button until the output section of the Effect

Routing Matrix begins flashing and the information line reads:

Output Mode: Stereo

• Use the Data Wheel to scroll through the available output config-

urations.

Note: Make sure you store the settings after you have changed

anything. See pg. 16 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 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).
