  • Page 4: Introduction

    INTRODUCTION Thank you for purchasing a Quadra/FX and congratulations! You now own one of the most sophisticated pieces of audio signal-processing technology available. The Quadra/FX uses state-of-the-art DSP techniques combined with A R T’s proprietary Dynamic Engine Allocation (DEA™) software to give you control over a multitude of brand new, stunning effects algorithms –...

  • Page 5: Quick Start Instructions

    QUICK START INSTRUCTIONS You’ve unpacked your Quadra/FX and you’re in a hurry to get it up and running. You probably would rather play with it than read the manual. Fair enough. First, check out the basics, outlined here, just to get your Quadra/FX on-line. It should take only a couple of minutes for you to read through this section and then you’ll be ready to fire up your new...

  • Page 6: Straight Into An Amp

    If you’re patching the Quadra/FX into a guitar (or other instrument) amplifier’s mono effects loop, use one cord between the amp’s effects send jack and the Quadra/FX’s Input #1. Run a second cord from Output #1 to the amp’s Effects Return jack. (If the amp has stereo returns, use another cord to connect the Quadra/FX’s...

  • Page 7: Try It Out

    Make sure that your mixer’s or amp’s send level control is turned up and that a signal is being sent to the Quadra/FX. Watch the Smart Meter on the front of the unit. Most of the red lights (LEDs) should be on, except for the +6 LED, which should only glow when a really loud, instantaneous signal reaches the unit.

  • Page 8: Installation

    INSTALLATION The Quadra/FX may be used in a variety of setups including with mixer channel inserts, mixers with reverb send and return facilities, and in the effects loop of an instrument or P.A. amplifier. Self-contained in an all-steel, single-height 19” rack-mount enclosure, the Quadra/FX is designed for continuous professional use. Because the unit is compact and lightweight, mounting location is not critical.

  • Page 9: Quadra/Fx Front Panel Controls And Indicators

    “live,” by plugging in another piece of equipment that you know works (try plugging into another outlet, too). If the outlet is good but the Quadra/FX does not turn on, consult your dealer or A R T Customer Service.

  • Page 10: Engine Button

    & ENGINE BUTTON The Quadra/FX contains up to four audio signal processors, or engines. Pressing this button and turning the Encoder will select an engine for editing (the selected engine LED will flash). Depending on the current routing, one or more engine LEDs may flash.

  • Page 11: Parameter Button

    * MIDI BUTTON + STORE BUTTON The Quadra/FX contains 100 memory locations. When you press the Store button, the Display flashes the current preset number. You can select any preset number to overwrite by turning the Encoder. Press Store again and the current preset will be saved to the location you selected. If you press any button other than Store, the save command will be aborted.

    . SMART METER LEDS / NUMERICAL DISPLAY (PRESET / VALUE) WINDOW NOTE: The rest of the LEDs on the front panel show the status of other Quadra/FX parameters. Consult the tutorials starting on page 15 for a thorough explanation of the Quadra/FX’s operation.

  • Page 13: Dry Kill And Global Mix

    Dry Kill is used to remove the unprocessed (dry) part of each preset’s signal from the Quadra/FX’s internal mix buss. One application for Dry Kill is when you are using the Quadra/FX with a mixer. In a typical mixing situation, a channel’s fader controls the level of the instrument patched into it. To add processing, a portion of the channel’s signal is often sent to an effect processor and the output of the processor is patched into another...

  • Page 14: Setting Dry Kill And Global Mix

    NOTE: With Dry Kill active, a preset’s Mix parameter now sets the level of all sound coming out of the Quadra/FX. For example, with a Mix setting of 0, no sound will come out of the unit (in other words, zero percent of the wet signal is allowed to pass).

  • Page 15: Midi Dump

    MIDI Dump By performing a MIDI Dump, you can save all of the Quadra/FX’s presets to an external device capable of recording MIDI data. You can even directly transfer the presets from one Quadra/FX to another one with a MIDI cable.

  • Page 16: Quadra/Fx Rear Panel Controls And Connections

    QUADRA/FX REAR PANEL CONTROLS & CONNECTIONS Despite the Quadra/FX’s sophistication, it is easy to interface the unit with other equipment. All inputs and outputs are located on the rear panel. Standard ¼” inputs and outputs make patching simple. Note: For best audio quality, always use high-quality cables.

  • Page 17: Output Level Switch

    The Input Level switch is similar to the Output Level switch, but is used for matching the level of the incoming signal to the Quadra/FX. The Input Level switch has two positions: in (instrument level) and out (line level). Be sure to check your other equipment’s manual for hints on setting its appropriate output levels.

  • Page 18: Tutorial

    TUTORIAL The best way to understand the Quadra/FX is to just jump in and edit some presets. It doesn’t take long and you’ll see how easy editing is due to the Quadra/FX’s intuitive layout. This section consists of four tutorials: Creating From Scratch, Just Editing , MIDI , and Advanced Application Notes .

  • Page 19: Creating From Scratch

    Cascade Stereo NOTE: See page 27 for more information on the Quadra/FX’s versatile routing configurations. TUTORIAL 1: CREATING FROM SCRATCH Routing: By editing any preset’s routing, you are essentially building a new preset from scratch. When routings are changed, the Quadra/FX reconfigures its internal architecture and loads in default effects.
  • Page 20 It should now sound like different effect algorithms are processing the audio entering the Quadra/FX; these are the default effects for the routing that you chose. To change an effect, you must first select its engine or engine group. If you chose Stereo Routing, there is only one available engine group and it is automatically selected for you.

  • Page 21: Just Editing

    Although both procedures are similar, this section illustrates a few minor points and shows an even easier way to perform both operations. NOTE: When routings are changed, the Quadra/FX reconfigures its internal architecture and loads in default effects. The preset’s former effects, class, and parameter values are all replaced. If you just want to tweak some values of an existing preset, be sure not to change routings.

  • Page 22: Faster Editing

    (See page 27 for more information on routings, engines, and connections.) All the rest of the lights on the Quadra/FX seem to change at fixed periods. This is because the front panel is sequentially showing you the state of all available engines. Watch the Engine LEDs. An Engine or Engine group lights along with its corresponding Effect and Class LEDs.

  • Page 23: Midi

    Channel Number: The MIDI channel number is the channel on which the Quadra/FX will receive and transmit all MIDI data. The Quadra/FX’s MIDI channel is global to the whole unit, regardless of which preset, routing, engine, or effect it is set from.

  • Page 24: Editing Midi Parameters

    Setting the MIDI Channel: To set the Quadra/FX’s MIDI channel, turn the Encoder to the left until the Channel LED flashes, then press the Encoder. Now all of the Smart Meter LEDs have gone out except for Channel and the Display shows a...
  • Page 25 NOTE: MIDI map can be set and changed from within any engine and it, along with the MIDI controller assignments (see the next section), need to be saved with the preset. Setting MIDI Controllers: Press the Encoder again to switch back to the parameter selection mode, where turning the Encoder scrolls through the six MIDI options.
  • Page 26 The available MIDI controllers are (aftertouch), and (pitch bend). Also, any external MIDI controller movement on the Quadra/FX’s MIDI channel will automatically set this value. See page 67 for more information on MIDI controllers. Press the Encoder again to switch back to the parameter selection mode, where turning the Encoder scrolls through the six MIDI options.

  • Page 27: Advanced Application Notes

    The Smart Encoder: The Quadra/FX’s reverb, delay, and rotary effects have certain parameters that can be triggered with a press of the front-panel Encoder. These functions allow you to audition a reverb’s sound, tap in new delay times, infinitely repeat a delay, or spin the rotary effect up and down.

  • Page 28: Smart Encoder Use

    To tap in a new delay time, press the Encoder at the desired tempo. The number of times that you press doesn’t matter; the Quadra/FX takes the average tempo. As you are tapping, you will hear the new delay time and see its value in the Display.

  • Page 29: Using The Smart Encoder While Editing Reverb, Delay, And Rotary Effects

    While editing delay effects, you can use the Encoder to tap in a new delay time. To do so, press and hold the Bypass button and press the Encoder at the desired tempo. The Quadra/FX keeps a running average of the time between all taps.

  • Page 30: The Quadra/Fx's Adjustable Parameters

    THE QUADRA/FX’s ADJUSTABLE PARAMETERS DESCRIPTION OF ROUTINGS AND ENGINES The Quadra/FX contains four engines that can be routed in four different ways. Our proprietary Dynamic Engine Allocation (DEA™) technology ensures that all DSP horsepower is effortlessly configured for your routing choice.

  • Page 31: Description Of Classes

    Stereo, the left and right channels of each processor remain separate, but any modulated parameter is linked. This routing uses all four Engines in the Quadra/FX as one “supercharged” stereo processor. Only Inputs and Outputs #1 and #2 are used; the other two are disabled. The left and right channels of the stereo processor remain separate, but any modulated parameter is linked between them.

  • Page 32: Description Of Effects And Their Parameters

    Bypass switch is the equivalent of turning the Mix control to 0. If Dry Kill is active, the MIX control will set the total output level of the Quadra/FX. (For information on Dry Kill, see page 10.) For example, if Dry Kill is active and MIX is set to 0, no sound will come from the unit. Conversely, if Dry Kill is active and MIX is set to 100, the highest effect output level is achieved.

    By varying the Size parameter from small to large, you can simulate spaces as small as a shower stall and as large as an elevator shaft. This The Rooms in the Quadra/FX approximate the impulse responses of different types of “real” rooms. At large Size settings, this algorithm simulates a large room such as a ballroom or a nightclub.
  • Page 35 REVERB CLASSES: Vocal The Vocal Reverb class can be used to sweeten and enhance the intelligibility or breathy qualities of a sound, particularly a vocal track. Bandwidth on longer decays is tailored to keep voices balanced in the tail. Instrument The Instrument Reverb is tailored for most solo instruments to maintain their tonal quality.

It can be adjusted from 0 to 255 milliseconds in 1-millisecond steps.
  • Page 37 Shape: Controls extra early-reflection delays that are used to modify the reverb envelope’s contour. This parameter’s range is from 0 to 31. Use Shape settings from 0 to 6 to modify the initial attack envelope. With settings from 7 to 23, the attack envelope stays constant, but spreads out in time. Settings above 23 create longer delays and a reverse slap.
  • Page 38 In the Dynamic Class, Special sets the Threshold that switches the Decay time from a minimum setting to the preset length. As with the above classes, Threshold can be set from 1 to 30 dB below unity gain. Normally, when the input signal is below the Threshold’s setting, the reverb’s decay time is as set. When the signal is higher than the Threshold, the Decay time is reduced.
