    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.

    Studio Quad V2 User's Manual 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 addition- al operating information.

    Studio Quad V2 User's Manual 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>...

  • Page 12: Input/output Configurations, Using Modifiers

    Studio Quad V2 User's Manual 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.

  • Page 13: Linking A Parameter To A Modifier

    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.

    Studio Quad V2 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 Studio Quad V2 provides you with this valuable A/B feature in the Compare function.

  • Page 16: About Modules And The Effect Charts

    Studio Quad V2 User's Manual SECTION 3 - EFFECTS AND PARAMETERS ABOUT MODULES AND THE EFFECT CHARTS The Studio Quad V2'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.

  • Page 17: Reverbs

    Studio Quad V2 User's Manual REVERBS Reverberation is probably the most widely used effect because it allows you to simulate the sound reflection charac- teristics 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.

    Studio Quad V2 User's Manual Reverbs PARAM. DESCRIPTION FX: Lvl Controls the signal input level fed to the Module. Varies from OFF to 100%. Dry: Lvl Controls the level of the dry (uneffected) signal. Ranges from OFF to 100%. Balance Controls the left/right positioning of the dry signal in the stereo soundfield.

    Studio Quad V2 User's Manual Reverbs (continued) PARAM. DESCRIPTION Blend The BLEND control cross-mixes reverberations from the left side into the right side and vice-versa. 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%. Prim &...

  • Page 20: Chorus And Flange

    Studio Quad V2 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 ampli- tude of the LFO.

  • Page 23: Phasers

    Studio Quad V2 User's Manual PHASERS 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.

  • Page 24

    Studio Quad V2 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. Tremolos and Auto Panners are similar to one another because they use an LFO to modulate the level of the signal. This allows you to re-create the tremolo effects commonly found on vintage instrument amplifiers.

  • Page 25

    Studio Quad V2 User's Manual DETUNERS / PITCH SHIFTERS Detuners are similar to pitch shifters, but the intervals between the detuned signal and the original are much small- er, usually expressed in cents (hundredths of a semitone). The Studio Quad V2 uses percentages of semitones to express the shifted note's distance from the original.

Dry: Lvl Controls the level of the dry (uneffected) signal. Ranges from OFF to 100%. Balance Controls the left/right posistioning of the dry signal in the stereo soundfield.

  • Page 27: Delays

    Studio Quad V2 User's Manual DELAYS A delay produces discrete, repeating echoes of the source material at a specified interval. In digital delays, the input signal is "sampled" or recorded into memory, where it is held for the amount of time you specify with the delay time setting, after which the sample is replayed at the output.

  • Page 28

    Studio Quad V2 User's Manual EQUALIZERS The Studio Quad V2 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 sig- nal together for equalization (thus eliminating the stereo image).

  • Page 29

    Studio Quad V2 User's Manual NOISE GATE / COMPRESSOR Noise gates are particularly useful for preventing mic rumble, wind noise, or hum from getting to tape in your recordings, or for gating drum kits to prevent mic bleed. Compression does exactly what its name implies; it compresses the dynamic range of the signal. It does this by turn- ing signals down as they become louder.

  • Page 30: Multi Effects

    Studio Quad V2 User's Manual MULTI EFFECTS MODULES The Studio Quad V2, 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.
