  • Page 5: Introduction

    Thank you for purchasing a DMV-PRO and congratulations! You now own one of the most sophisticated pieces of audio signal-processing technology available. The DMV-PRO 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—many of which have never been heard before.

  • Page 6: Installation

    INSTALLATION The DMV-PRO 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 DMV-PRO is designed for continuous professional use. Because the unit is compact and lightweight, mounting location is not critical.

  • Page 7: Quick Start Instructions

    For a mixer with a mono send, use only Input #1. Connect Outputs #1 and #2 to two input channels or the returns on your mixer. The DMV-PRO can be used as two separate, stereo effect-processors. Inputs and Outputs #3 and #4 correspond to the DMV-PRO’s second stereo engine. Again, if your mixer has a mono send, use only Input #3.

  • Page 8: Straight Into An Amp

    PRO’s Output #2 and the amplifier’s other input. You can also plug a second output from your instrument (or the output from another instrument) into the DMV-PRO’s Input #2. Don’t forget that the DMV-PRO can also be used as two separate, stereo processors, or even as four separate, mono processors. Imagine the Power! IN AN AMP’S EFFECTS LOOP: If you’re patching the DMV-PRO into a guitar (or other instrument) amplifier’s mono effects loop, use one cord...

  • Page 9: Try It Out

    TRY IT OUT: Turn on your amp or mixer and monitor amplifier. Make sure that your mixer’s or amp’s send level control is turned up and that a signal is being sent to the DMV-PRO. Watch the Meters on the front of the unit. Most of the lights (LEDs) should be on, except for the +6 LED, which should only glow when a really loud, instantaneous signal reaches the unit.

  • Page 10: Dmv-Pro Front Panel Controls And Indicators

    DMV-PRO FRONT PANEL CONTROLS & INDICATORS PROCESSORS (A) AND (B) The DMV-PRO contains two audio processors, labeled Processor (A) and Processor (B). Each can be operated independently from the other. The controls for each processor operate similarly and are outlined below.

  • Page 11: Processor (A) & (B) Encoder / Switch

    Encoder’s function between selecting parameters and changing values. For more information on parameters, see page 28. PROCESSORS (A) & (B) ENCODER / SWITCH The first two Encoders are used separately to view and modify their corresponding processor’s parameters and effects. The Encoders can be turned and pressed while editing, and their action is explained in the previous paragraph.

  • Page 12: Preset Encoder / Switch

    option is available as an effect parameter. See the parameter descriptions on page 28 for more information on bypassing individual effects. PRESET ENCODER / SWITCH currently are viewing, so you will not be hearing the effects or routing that you see on the front panel. To load a preset, press the Preset Encoder.

  • Page 13: Unloaded Preset Indicator

    UNLOADED PRESET INDICATOR PRESET DISPLAY SPECIAL FUNCTIONS: Restoring Presets to Original Factory Settings The DMV-PRO can overwrite all stored presets with its original factory settings. This process is called a Factory Reset. WARNING: A Factory Reset erases all customized presets. If you have saved some favorite programs, either scroll through their parameters and write them down, or use the MIDI Dump feature to off-load your presets to a MIDI storage device before implementing a factory reset.

  • Page 14: Dry Kill And Global Mix

    Dry Kill and Global Mix Dry Kill and Global Mix are two related functions that allow you to quickly alter the ratio of wet (processed) and dry (unprocessed) sound coming out of the unit. Normally, the Mix parameter sets this ratio separately for each preset, but by using Dry Kill or Global Mix, you can change these settings for all presets at once.

  • Page 15: Setting Dry Kill And Global Mix

    Setting Dry Kill and Global Mix: To adjust Dry Kill or Global Mix, press the MIDI/Util button. Turn the Preset Encoder until [ appears on the top line of LCD (A). Turn Encoder (A) to switch the bottom line of LCD (A) between ON and OFF.

  • Page 16: Dmv-Pro Rear Panel Controls And Connections

    DMV-PRO REAR PANEL CONNECTIONS Despite the DMV-PRO’s sophistication, it’s 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. The DMV-PRO is designed for line level or instrument operation.

  • Page 17: Outputs #1-4

    OUTPUTS #1–4 All four Outputs are single-ended (unbalanced) ¼” jacks with low impedance. A preset’s routing determines the use of each Output jack. For example, Cascade and Multi FX Routings do not use Outputs #3 and #4. For more information on the different configurations of the DMV-PRO’s inputs and outputs, see page 26 and the tutorial starting on page 14.

  • Page 18: Tutorial

    #4 are always controlled by Processor (B). Resource distribution between the inputs and outputs is automatically handled by our proprietary Dynamic Engine Allocation (DEA™) technology. DEA allows for the following creative signal-routing options: Twin Stereo Twin Stereo routing contains two effect-processors with two linked engines each. The result is two true- stereo effects.
  • Page 19 Cascade Discrete 4 (mono) Multi FX Multi FX routing combines the signal from Inputs #1 and #2 and runs it in series through Engines #1 and #2. The signal is then split and fed to both inputs of linked engines #3 and #4, which are running in true-stereo. The signal from Engine #3 is sent to Output #1 and the signal from Engine #4 is sent to Output #2.

  • Page 20: Tutorial 1: Starting From Scratch And Changing Effects

    Processor (B)’s effect since its inputs and outputs correspond to Inputs and Outputs #3 and #4. Mono Routings: Multi FX and Discrete 4 routings have two separate mono effects on one or both of the processors. (See the beginning of this tutorial for more information on routings.) Setting two effects per processor is similar to setting one, like in True Stereo routing.
  • Page 21 Repeatedly press the Routing button until the Discrete 4 Routing LED is lit. Observe both LCDs. Again, the DMV-PRO has loaded default effects for Discrete 4 routing, but notice that there are now two effects in each LCD. Look at LCD (A). The top line now corresponds to Effect #1 (at Input and Output #1) and the bottom line corresponds to Effect #2 (at Input and Output #2).

  • Page 22: Tutorial 2: Editing Effect Parameters

    Follow the instructions: Use the Preset Encoder to select the preset number that you want to overwrite (you don’t have to turn the encoder if you just want to overwrite the current preset). When you are ready, press the Store button to confirm the operation. If you press any button other than Store, or if Store isn’t pressed within 10 seconds, the save command will be aborted.

  • Page 23: Tutorial 3: Midi

    Repeat this process to switch back and forth between a processor’s effects. Processor (B)’s effects are edited in the same manner. Don’t forget that Processors (A) and (B) are completely independent and can be edited at the same time!

  • Page 24: Editing The Global Midi Parameters

    this ordering. You could, for example, set a received program change value of 1 to recall DMV-PRO preset #40, a program change value of 2 to recall DMV-PRO preset #5, and a program change value of 3 to also recall DMV-PRO preset #5. Like MIDI Channel, the DMV-PRO’s MIDI Map is set in MIDI/Util Mode and is automatically saved when changed.

  • Page 25: An Effect's Midi Parameters

    Next, turn Encoder (A) to select an incoming MIDI program change number that you wish to map. This control’s range is from 1 to 128. Turn Encoder (B) to set the corresponding DMV-PRO preset number that will be recalled when the program change number in LCD (A) is received. The range of DMV-PRO preset numbers is from 1 to 100, or OFF to disable a program change number from recalling any DMV-PRO preset.
  • Page 26 controller’s value linearly corresponds to the key, velocity, or aftertouch value being played. For example, if MIDI CC Number was set to Note On and Mode was set to Continuous, then the controller’s value would equal the key number played. Key, Velocity, or AT Value If Mode is set to Toggle, a second parameter becomes available to set the key, velocity, or aftertouch value that will toggle between the controller values 0 and 127.

  • Page 27: Tutorial 4: Advanced Applications

    TUTORIAL 4: ADVANCED APPLICATIONS The Smart Encoder: pressing the Edit and Encoder buttons. Using the encoders this way is called “smart” because parameters can be automatically changed, instead of by having to manually scroll through a series of menus and values. The table below lists all of the Smart Encoder functions and the effect-classes they are available from.

  • Page 28: Smart Encoder Programming

    Rotary The Rotary Spin High/Low option allows the Encoder to toggle the rotary speed between a high and low spin rate (alternating with each Encoder press). Smart Encoder Programming: Smart Encoder operation is set with an effect’s parameters. To program Processor (A)’s Smart Encoder, first select a preset with a Processor (A) effect and class that uses one of the Smart Encoder functions (see the table above).

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

    Smart Encoder Functions while Editing Reverb, Delay, and Rotary Effects: Smart Encoder functions are automatically set up to work while editing reverb, delay, and rotary effects. For Reverb effects, a reverb impulse can be triggered while adjusting any of the reverb’s parameters; this helps you hear the reverb changes as you are making them.

  • Page 30: The Dmv-Pro's Adjustable Parameters

    Cascade: This routing turns the DMV-PRO into two true-stereo processors. Inputs #1 and #2 feed the first processor (consisting of grouped Engines #1 and #2) and exit at Outputs #1 and #2, and Inputs #3 and #4 feed the second processor (consisting of grouped Engines #3 and #4) and exit at Outputs #3 and #4.
  • Page 31 Multi FX: Multi FX routing uses the DMV-PRO’s processors to create a three-engine multi-effect chain. Since most engines contain a separate effect, EQ, delay, and dynamics sensing section, the actual multi-effect lengths can be quite long. This routing gives you tons of power to creatively shape your sound.

  • Page 32: Description Of Classes

    DESCRIPTION OF CLASSES Each effect has six classes, which are effect variations. The class name generally denotes the application for which the class was optimized. For example, The Vocal class of reverbs is designed to enhance voice-type inputs. Descriptions of all effects and their classes begin on page 31. The following, though, are some class generalizations: Ducking classes use ramped dynamics processing to create smooth “ducking”...
  • Page 33 Effect Class: Classes are effect variations and are named after the applications they are optimized for. Each effect has six classes and their names, sounds, and adjustable parameters vary based on the effect. (See page 31 for a description of all effects and their classes.) This parameter sets the ratio of unprocessed (dry) sound to processed (wet) sound, with a range from 0% to 100% (0 = all dry, 100 = all wet).
  • Page 34 MIDI Parameters Effects can have up to four controller assignments (designated a, b, c, and d) that can modify any of its parameters in real-time. Each of the four assignments has separate settings for the following parameters: CC Channel, MIDI CC Number, Parameter, Value Low Range, and Val. High Range. See the tutorial on page 21 for information on setting the controller assignments.

  • Page 35: Chamber Reverb

    The Chamber Reverb simulates a reflective enclosure (perhaps made of wood or concrete) with a sound source at one end and a microphone near the other. 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 reverb is more reflective and has a more defined echo characteristic than Halls or Rooms.

  • Page 36: Reverb Parameters

    Instrument The Instrument Reverb is tailored for most solo instruments to maintain their tonal quality. High frequency decays are not limited and low frequencies are controlled to prevent muddiness. An auxiliary gate is available to dynamically process the sound. Concert The Concert Reverb has a neutral high frequency response with a low frequency decay emphasis.
  • Page 37 (greater than 3 seconds) are usually used for “bigger than life” special effects. Both the Decay and Size parameters should be used together to set the overall impression of the simulated space. Decay Enabled: In the Dynamic Class, this control sets the input level range that switches the Decay amount from the preset value to 0.
  • Page 38 Length: Sets the length of the gated reverb, from 50 to 500 milliseconds. Motion: Sets the movement of the reverberation tail. This control is used to help make long decay times sound more natural. When turned on, this control’s range is from 1 to 9 and is normally set at 1, producing a very subtle effect.

  • Page 39: Digital Delay

    These algorithms delay a signal in time. The maximum delay length, per channel, is 1.25 seconds. Up to twelve delay taps are available and can be equally and unequally spaced within the span of the delay length. Some delay classes have dynamics sensing, which can use input level to switch the effect in and out or change the Regeneration value.

  • Page 40: Delay Parameters

    Dynamic The Dynamic Delay uses input level to switch the Regeneration amount between its preset value and 0.

  • Page 42: Pitch Transposer

    The Pitch Transposer (PT) algorithm can change the base-pitch of a sound. Each PT class contains an auxiliary digital delay that feeds back into the pitch-shift to create falling or rising pitch effects. Some classes also have dynamics sensing, which can use input level to switch the effect in and out or trigger the Whammit! effect (see below). PITCH CLASSES: Micro 2 Voice Micro 2 Voice is the ultimate double tracking algorithm.
  • Page 43 PITCH PARAMETERS: Buffer Size: This control sets the loop length and splicing characteristics of the PT. Two of the four settings, Smooth- Long and Smooth-Short, are optimized for the smoothest sound, but need a fixed amount of transport delay. The other two settings, Smart-Long and Smart-Short, utilize a looping technique that varies the amount of transport delay based on the Pitch setting.

  • Page 44: Modulated Effects

    Chorus, flanger, phaser, tremolo, and panner are modulated effects. They use a Low Frequency Oscillator (LFO) to sweep certain aspects of the effect’s sound. LFO Speed determines the movement (sweep) rate and the LFO Shape determines the sweep pattern. Some of the classes have dynamics sensing, which can use input level to switch the effect in and out or trigger the LFO.

  • Page 45: Phaser

    Classic, Jazz Chorus, MXR “Grey,” and MXR “Phase 90,” These classes recreate the sound of the “classic” effects. The LFO parameters and sometimes Bandwidth are controlled to produce the characteristic sound and control action. For example, as LFO Speed is increased, Width is automatically adjusted within a musical range.

  • Page 47 Effect Enabled: In Ducking and Gated classes, this control sets the audio input level that controls the gating action of the effect. Signals that fall within its setting (for example, above –10 dB) are heard and ones that are not are muted.

  • Page 48: Rotary

    The Rotary effect simulates a 2-way rotating-speaker cabinet with a built in crossover network. Rotating speakers are traditionally used with electric organs, but contemporary uses include with guitars, vocals, drums, and just about any sound that needs some added motion. Since this effect creates a stereo simulation, it is not available with mono effects.
