In this application, the source is routed directly to the mixer channel input(s).
7 Quad 4 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.
8 Quad 4 User's Manual SECTION 2 - BASIC FUNCTIONS OF THE STUDIO QUAD 4 GETTING AROUND THE OPERATING SYSTEM The menu structure of the Quad 4 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.
9 Quad 4 User's Manual 3) Select a Default for the selected effect Type The Default parameter allows you to select one of several effect settings stored in the Quad 4's library. For example, there are 13 Stereo Reverb defaults to choose from. Each default is available in any program that uses the same size effect module.
10 Quad 4 User's Manual SELECTING EFFECT AND INPUT / OUTPUT CONFIGURATIONS The Quad 4'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. The Quad 4 gives you the ability to select any one of the 16 different effect configurations within any program by performing the following procedure: 1.
11 Quad 4 User's Manual 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.
12 Quad 4 User's Manual Pressure or Aftertouch), L - 1 (LFO1), L - 2 (LFO2), or DYN (Dynamic). NOTE: Make sure you store any changes you make. See pg. 13 for more information SETTING UP AN LFO OR DYNAMIC MODIFIER To link an LFO to a parameter, please do the following: 1. Press the button until you reach the modifiers edit mode. The modifiers icon begins to flash in the bottom right corner of the screen. 2. Use the and buttons to scroll to Page 9.
13 Quad 4 User's Manual COMPARING PROGRAMS During the course of editing Programs, you may find that you want to compare the edited version of the Program to the original, stored version. Fortunately, the Quad 4 provides you with this valuable A/B feature in the Compare function. To compare an edited Program with the original Stored version, do the following: 1. After having altered a program, press the and buttons together. The top line of the display reads: *COMPARING ORIGINAL PRG*.
14 Quad 4 User's Manual SECTION 3 - EFFECTS AND PARAMETERS ABOUT MODULES AND THE EFFECT CHARTS The Quad 4's diverse selection of effect modules allows you to achieve nearly endless combinations of effects and routings. To accomplish that goal, we've supplied you with several different module types in an effects configuration. The processing resources are divided one of four ways. Fig. 3-1 below uses pies to represent the possible resource division combination of the S-DISC II.
15 Quad 4 User's Manual REVERBS Reverberation is probably the most widely used effect because it allows you to simulate the sound reflection characteristics of almost any kind of room. In a real room, reverb is a result of sound reflecting off room surfaces such as the walls, floor, ceiling, and objects in the room. The materials, size, and shape of the room determine how long these reflections echo and decay before dying out completely.

This can be used to increase the realism of the simulated room by adding reverberations from different parts of the room to each channel. Varies from 0% to 99%.
18 Quad 4 User's Manual CHORUS AND FLANGE Both choruses and flangers use a Low Frequency Oscillator (LFO) to produce their rich, swirling effects. When you change the speed and depth parameters of modulation effects, you're actually controlling the frequency and amplitude of the LFO. These settings determine the rate and intensity of the modulation effect. 10 -5 cents 0 5 cents P I T C H 10 In general, here's how choruses and flangers work.

21 Quad 4 User's Manual PHASERS D ua lP St ha er s eo e Ph as e Phasers create a copy of the original signal and modulate that new signal’s phase relationship to the original signal. When the two signals are reunited at the output, the modified signal, moving smoothly in and out of phase, causes continuous cancellations and reinforcements at different frequencies throughout the modulating cycle. PARAM. DESCRIPTION Phasers ✓ ✓ FX: Lvl Controls the signal input level fed to the Module.
22 Quad 4 User's Manual ROTARY SPEAKER SIMULATOR / TREMOLO / AUTO PANNER The Rotary Speaker Simluator allows you to emulate the classic rotating speaker sound, without the chiropractic problems that come with moving bulky speaker cabinets. R ot ar St y S . T pe a r A em ker ut ol o Sim o Pa . nn er Tremolos and Auto Panners are similar to one another because they use an LFO to modulate the level of the signal.
23 Quad 4 User's Manual DETUNERS / PITCH SHIFTERS Detuners are similar to pitch shifters, but the intervals between the detuned signal and the original are much smaller, usually expressed in cents (hundredths of a semitone). The Quad 4 uses percentages of semitones to express the shifted note's distance from the original. For example, with a maximum detune setting of 50%, the pitch is exactly one semitone (50 cents) up from the original.

26 Quad 4 User's Manual EQUALIZERS The Quad 4 has a broad selection of equalizer Modules to cover virtually any need. Both mono and stereo modules are available. Remember that mono equalizers connected to stereo sources will always sum the stereo signal together for equalization (thus eliminating the stereo image). If you need to maintain the stereo image, use a stereo equalizer module. The Parametrics allow you to cover very specific regions of the sound spectrum with extreme precision and control.

28 Quad 4 User's Manual MULTI EFFECTS MODULES C ho ru Fl s/D an e ge lay /D el ay The Studio Quad 4, Multi Effect Modules allow the User to combine either Delay and Chorus or Delay and Flange within one Effect module block. This is ideal for situations where the User needs to add another effect to the Effect Configuration, but is running low on signal processing resources. Within the module, there is a unqiue parameter that allows you route the signal several different ways between the two effects.
29 Quad 4 User's Manual SECTION 4 - INPUT LEVELS & UTILITIES AUTOMATIC INPUT LEVELING Proper input level adjustment can be the difference between an acceptable recording and a great recording. Fortunately, the Studio Quad 4 has the ability to automatically optimize your input levels based on the signal sent to the input(s). The concept of Auto Leveling is simple: the Studio Quad 4 listens to the signal for approximatley 8 seconds, and sets the input levels accordingly.
