8 Studio Quad Owner's Manual 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 processing with a console.
9 Studio Quad Owner'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.
10 Studio Quad Owner's Manual 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.

12 Studio Quad Owner's Manual 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.
13 Studio Quad Owner's Manual 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 configuration you want to use.
14 Studio Quad Owner's Manual MIDI CCs - When you use MIDI CCs, the Studio Quad 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. 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.
15 Studio Quad Owner's Manual • 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 THRU effect 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 select the minimum Parameter value you want when the controller is in the minimum position.
16 Studio Quad Owner's Manual • Press <3> and use the Data wheel to adjust the speed of the LFO cycle. The assigned Parameter now follows the modulating waveform of the LFO you selected. See pg. 23 for waveform diagrams. To setup the Dynamic Modifier, do the following: • Press until you see “modifiers” flashing in the bottom right corner of the screen. • To adjust the settings of the Dynamic Modifier, use the and keys to scroll to Page 10.

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.
30 Studio Quad Owner's Manual EQUALIZERS The Studio Quad 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.

Noise Gate DESCRIPTION ✓ Level INPUT LEVEL - Controls the signal input level fed to the Module. Varies from OFF to 100%. ✓ ThshO OPEN THRESHOLD - Sets the level at which the gate begins to open at the rate set by ATTACK. Both THSHO and THSHC are independent controls.
32 Studio Quad Owner's Manual SECTION 4- IN LEVELS & UTILITIES AUTOMATIC AND MANUAL INPUT LEVELING Proper input level adjustment can be the difference between an acceptable recording and a great recording. Fortunately, the Studio Quad 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 listens to the signal for about 8 seconds, and sets the input levels accordingly.
33 Studio Quad Owner's Manual UTILITY There are settings in the Studio Quad that affect many things simultaneously. They can be found in the Utility menu, and are considered "global" settings. This list of items includes: display contrast, MIDI assignments, system exclusive options, etc. The Utility section contains seven Pages. To access Utility mode, press once. Once inside, you can use the , , <1> - <4> buttons, and the Data wheel to navigate through Utility mode.
