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. However, for greater reliability we recommend that you not place the
DMV-PRO on top of power amps, tube equipment, or other sources of heat.
AC POWER HOOKUP
The DMV-PRO has an external power supply designed to operate at 110 VAC @ 50 to 60 Hz. Units
manufactured for use outside the United States of America have been modified to comply with the required
electrical specifications. Only use the adapter that came with the DMV-PRO. If the adapter becomes lost or
damaged, contact A R T Customer Service for replacement.
AUDIO CONNECTIONS
All audio connections to and from the DMV-PRO are ¼” unbalanced TS (Tip = Hot, Sleeve = Ground). We
recommend using only high-quality shielded cables equipped with high-quality connectors.
SAFETY PRECAUTIONS
Warning: To avoid the risk of shock or fire, do not expose this unit to moisture. Refer all servicing to qualified
personnel. Do not remove the metal covers; there are no user-serviceable parts inside. Only use the power
adapter that came with this unit or one obtained from A R T’s Customer Service Department.

QUICK START INSTRUCTIONS
You’ve unpacked your DMV-PRO 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 DMV-PRO 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
unit. Later, when you want to get into more of the details, check out the rest of the manual.
QUICK SETUP:
Plug the AC adapter into the back of the DMV-PRO and then into a wall socket. Make sure that both the Input
Level and Output Level switches (on the back of the unit) are fully out. You may need to depress these
switches later, after the other setup steps are done.
NOTE: For all input and output connections, always use high quality, shielded cables.
WITH A MIXER:
Connect two cords with ¼” plugs between your mixer’s auxiliary sends and the DMV-PRO’s Inputs #1 and #2.
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. The DMV-PRO can even be used as four completely independent, mono effect-processors. As you would
expect, Inputs #1–4 correspond with Outputs #1–4.
IMPORTANT: If you are patched in a send/return fashion and mixing an instrument’s dry (unprocessed) signal
with processed sound from the DMV-PRO (on separate faders), you will want to remove all dry signal from
the DMV-PRO’s internal mix buss (signal path). This allows the dry signal to appear only once at the mixing
board and not additionally at the DMV-PRO’s faders. One way to do this is to set EACH preset’s Mix
parameter to 100%. That would be a tedious process! Fortunately, there is a special DMV-PRO function

- 4 -
called Dry Kill that will conveniently turn off the dry signal path inside the unit. Each preset’s Mix value is still
retained, even though all dry sound is eliminated. To enable Dry Kill, turn on the DMV-PRO and press the
MIDI/Util button. Turn the Preset Encoder (the knob on the far right of the unit) until the top line of LCD (A)
reads: “Dry Kill:” then turn Processor (A)’s encoder until “ON” appears on the bottom line. By enabling Dry Kill,
you have turned off or “killed“ the path for dry sound. Press the MIDI/Util button again to exit the MIDI/Util
Mode. For more information on Dry Kill, see page 10.
STRAIGHT INTO AN AMP:
If you’re patching the DMV-PRO into an instrument amplifier or stereo monitor amplifier, use one cord
between the instrument and the DMV-PRO’s Input #1. Run a second cord from Output #1 to the amp’s input.
If the amp has stereo input capabilities, or if you’re using two amps, connect another cord between the DMV-
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
between the amp’s Effects Send jack and the DMV-PRO’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 DMV-PRO’s
Output #2 to the amp’s other Effects Return jack.) Again, don’t forget that the DMV-PRO has the power to act
as two separate, stereo processors or four separate, mono processors.

- 5 -
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. If the +6 LED
glows constantly, turn down the send level from your mixer or instrument. If only a few LEDs glow, either turn
up your mixer’s send level, or depress the Input Level switch on the back of the unit and then adjust the
mixer’s send level accordingly.
Now raise the return level on your mixer or amp. You should be hearing the DMV-PRO’s effect. If not, check
your connections and your monitor amp. Make sure that the DMV-PRO’s Bypass button hasn’t been pushed
accidentally; if it has, the Preset Display will read -, To turn Bypass either off or on, press the front-
panel Bypass button. If the DMV-PRO’s level seems too high, depress the Output Level switch on the back of
the unit.
SELECTING PRESETS:
The DMV-PRO is in Preset Mode when it is powered up. Select a new preset by turning the Preset Encoder
(on the far right) to any preset number that you desire. Notice that the information on the front-panel has
changed to reflect the new preset’s configuration. Also notice that the Load LED (above the numeric display)
is lit to indicate that you are looking at an unloaded preset. You won’t hear an unloaded preset until you press
the Preset Encoder to load it. For a list of Factory Presets, arranged according to number and type, see page
48. Editing effects will be covered later in this manual.
NOTE: The DMV-PRO can handle up to two stereo channels and up to four mono channels, depending on
how a preset is internally “routed.” Some of the factory presets may use a routing scheme (Twin Stereo,
Cascade, Discrete 4, or Multi FX) that is different from how your rig is currently configured. You may not hear
what you would expect to hear. For instance, you may be set up to only monitor stereo outputs (#1 and #2),
and you may be listening to a preset that creates four separate flangers in a Discrete 4 routing (four effects
with separate inputs and outputs). Obviously, you will not hear all four flangers because you are not listening
to Outputs #3 and #4; you will only hear the two flangers at Outputs #1 and #2. Unmatched routing schemes,
however, can still produce creative results. For example, in the previous situation, the Discrete 4 flanger
preset would yield a stereo flanger, but with completely independent (unlinked) left and right channel sweep
widths and rates! When is the last time you easily created THAT effect? The DMV-PRO has many similarly
unique sounds and features, all of which will be covered in the rest of this manual. For your reference, more
information on the concept of routings can be found on page 26 and a list of all factory presets and their
routings begins on page 48.

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.
& POWER
The Power switch turns the DMV-PRO on and off. The Numerical Display Window and both LCDs illuminate
when power is on. If the unit does not turn on when this switch is toggled, check the AC power cord and
adapter. Also, make sure the outlet that it is plugged into is “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 DMV-PRO does not
turn on, consult your dealer or A R T Customer Service. The DMV-PRO is in Preset Mode when it is first
turned on.
' LCD (A) AND (B)
The DMV-PRO contains two Liquid Crystal Displays—LCD (A) and LCD
(B). Both displays separately show information about their corresponding
processor and when the MIDI/Util button is pressed, they both work
together for viewing global parameters.
To set the LCD View Angle of the displays, press the MIDI/Util button and then turn the Preset Encoder to the
right until [  ($5 T&+$A ] appears in LCD (A). Turn Encoder (A) until the contrast is better for both
LCDs. Press the MIDI/Util button to return to the previous mode.
( EDIT BUTTONS (A) AND (B)
The Edit buttons are used for viewing each processor’s effect parameters. From Preset Mode,
press Edit and turn the same processor’s Encoder to view each effect parameter. To modify a
parameter, press the Encoder and then turn it to change values. Repeatedly pressing the Encoder will toggle

- 7 -
the 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. When the MIDI/Util button is pressed, both Encoders work
together to set global parameters: this is explained in the MIDI/Util paragraph below. In Preset Mode, the
Encoders can be turned and pressed to select and load new effects. See the tutorials starting on page 14 for
more information.
* ROUTING BUTTON
Routings control the way that sound is processed through the DMV-PRO and how each Input feeds each
Output. Repeatedly pressing the Routing button will scroll through the four internal, audio routings: Twin
Stereo, Cascade, Discrete 4, and Multi FX. (For a description and diagram of each routing, see page 26.) If
you press the Routing button while editing a preset, the LCDs will display the warning message. BE
CAREFUL! When routings are changed, the DMV-PRO reconfigures its internal architecture and loads in
default effects. The preset’s former effects, class, and parameter values are all replaced.
+ MIDI/UTIL BUTTON
Press the MIDI/Util button to edit the DMV-PRO’s global parameters: MIDI base channel, program change
mappings, Dry Kill/Global Mix settings, LCD view angle; and also to perform a MIDI dump and Factory Reset.
After pressing the MIDI/Util button, turn the Preset Encoder to scroll both LCDs through different lists of global
parameters. When you see the parameter that you want to change in one of the LCDs, turn its corresponding
Encoder to change values.
, STORE BUTTON
The DMV-PRO contains 100 memory locations. To store a preset in one of these locations, press the Store
button. The Preset Display will flash the current preset number. Turn the Preset Encoder to select a preset
number to overwrite or just leave it on the current one, if desired. Press Store again and the current preset will
be saved to the location you selected. If you press any button other than Store or don’t press another button
within 10 seconds, the save command will be aborted. See the tutorial on page 17 for more information on
storing presets.
- BYPASS BUTTON
When the DMV-PRO is bypassed, all processed sound is blocked from reaching the outputs, leaving only dry
(unprocessed) signal. Press the Bypass button to toggle Bypass on and off. (When Bypass is on, the Preset
Display alternates between the current preset number and -, .) Individual effects can also be bypassed; this

- 8 -
option is available as an effect parameter. See the parameter descriptions on page 28 for more information on
bypassing individual effects.
. PRESET ENCODER / SWITCH
The Preset Encoder is used to change presets. As you turn it, the number in
the Preset Display changes, as does the information in both LCDs and the
Routing Display; these are showing you information about the new preset.
Notice that the light on top of the Preset Display is lit once you have turned the
encoder. This light indicates that you have not yet loaded the preset that you
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.
When the MIDI/Util button is pressed, the Preset Encoder is used to scroll through the DMV-PRO’s global
parameters. LCDs (A) and (B) will show a different set of parameters. To change a parameter’s value, turn its
corresponding encoder.
/ SELECTION ARROW
The Selection Arrow appears on the left side of an LCD and is used to
distinguish the active line. For example, in the picture on the right, the
Selection Arrow indicates that Chorus is the selected effect and it will be
affected by turning the encoder or pressing the Edit button. To select the
other line, press the same processor’s encoder. While editing, the Selection Arrow is used to differentiate the
active parameter or value field.
0 PROCESSOR (A) & (B) METERS
The meters show the level of signal entering each processor. They either display the level for the
current effect’s input (while editing) or both combined inputs of each processor (when in Preset mode).
To optimize the levels entering the DMV-PRO, watch the +6 LED. If it is constantly lit, the digital
processor is getting too much input level and may clip; turn down the signal going to the DMV-PRO. For
maximum dynamic range, the meter LEDs should be lit most of the time, with the +6 LED briefly flashing on transients
(high-energy bursts, such as loud snare drum hits).
1 ROUTING LEDS
The DMV-PRO has four signal-routing options: Twin Stereo, Cascade, Discrete 4, and
Multi FX. For a description and diagram of each routing, see page 26. Routings are
selected by repeatedly pressing the Routing button (see the above Routing Button
paragraph).

- 9 -
2 UNLOADED PRESET INDICATOR
When you turn the Preset Encoder to view presets, the DMV-PRO’s sound won’t
change until you press the Preset Encoder to load the preset. The Unloaded
Preset Indicator is a reminder that you are viewing an unloaded preset.
3 PRESET DISPLAY
The Preset Display shows 3 alphanumeric characters that correspond to the
current preset number, whether it’s presently loaded or not. When the Preset
Display is flashing a preset number, it is because you have entered Store mode
and pressing the Store button will overwrite the current preset number’s contents.
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.
(See page 11 for information on the DMV-PRO’s MIDI Dump.)
To perform a Factory Reset, follow these steps:
1) Press the MIDI/Util button. 2) Turn the Preset Encoder until [
0$11 #(2 %-0  "2-08 $1$2 : ]
appears in LCD (B). 3) Press the Edit (B) button and notice that LCD (B) is now flashing [ 0$11 #(2 2-
"-T%(0, $1$2 : ]. 4) Press Edit (B) again to confirm that you really want to perform a Factory Reset. If
Edit is not pressed again within 10 seconds, or if any other button except for Edit is pressed, the DMV-PRO
will exit from Factory Reset mode with your former presets still intact.

- 10 -
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.
Dry Kill is used to remove all dry sound from the DMV-PRO’s internal mix buss. One application for Dry Kill is
when you are using the unit 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 channel. Now two faders control the overall
sound; the first fader still controls the instrument’s level (all dry) and the second one controls the DMV-PRO’s
level (normally a mix of wet and dry signal). As you can see, dry sound appears at both faders and can result
in an unbalanced mix of sounds. This is particularly noticeable when using a flanger, phaser, or chorus since
these effects are strongest with an equal mixture of both parts. Also, too much dry signal can result in a
diluted sound. By using Dry Kill to remove all dry signal from the DMV-PRO’s output, each fader will only
control one part of the sound and you will be able to blend the two easily at the mixing console.
With Dry Kill active, a preset’s Mix parameter sets the level of all sound coming out of the DMV-PRO. For
example, with a Mix setting of 0, no sound will come out of the unit because the dry part has been disabled
and zero percent of the wet signal is now allowed to pass.
NOTE: If you are plugging directly into the DMV-PRO and just listening to your instrument through the DMV-
PRO's outputs, do not set Dry Kill; use each preset’s Mix parameter to balance your sounds.
Global Mix is a function similar to Dry Kill, though it doesn’t necessarily remove all dry sound. Global Mix is a
simple way to set each preset’s Mix parameter to a certain value. For example, if Global Mix is set to 50%, all
presets’ Mix values will become 50% (half dry and half wet), regardless of individual Mix parameter settings.
This function is useful when you quickly want to audition all presets with the same Mix level. The change isn’t
permanent; as soon as you turn off Global Mix, the presets will return to their originally stored Mix levels. You
can change and resave a preset’s Mix level with Global Mix active. You will hear Mix changes as you’re
making and saving them, but as soon as you switch to a different preset or back to the changed one, the
Global Mix value will again override the setting that you just made. Of course, when you turn Global Mix off,
the saved Mix value will be the one that you hear.
Here’s a trick to quickly set several presets’ Mix parameters to a new value: Set Global Mix to whatever value
you desire, call up each of the presets you wish to change and individually save them (just press the Store
button twice). You don’t have to edit anything! When you turn Global Mix off, the newly-saved presets will
have their Mix values set to whatever Global Mix was originally set to. All other presets will remain
unchanged.

- 11 -
Setting Dry Kill and Global Mix:
To adjust Dry Kill or Global Mix, press the MIDI/Util button. Turn the Preset Encoder until [ 08 (++A ]
appears on the top line of LCD (A). Turn Encoder (A) to switch the bottom line of LCD (A) between ON and
OFF. If Dry Kill is on, the effect’s dry path is disabled. If Dry Kill is off, dry sound is allowed to pass and each
preset’s Mix control governs the ratio of dry and wet signal. Also, if Dry Kill is off, LCD (B) displays the Global
Mix setting. By turning Encoder (B), you can turn Global Mix OFF or set it to a percentage between 0 and
100.
Changing Dry Kill or Global Mix takes effect immediately and does not have to be saved. To exit MIDI/Util
mode, press the MIDI/Util button.
NOTE: The Dry Kill state is retained when turning the DMV-PRO on and off. The Global Mix state, however, is
not retained; the unit defaults to each preset’s stored Mix level when turning power on (i.e., Global Mix OFF).
MIDI Dump
By performing a MIDI Dump, you can save the DMV-PRO’s presets and MIDI Map to an external MIDI-
recording device. You can even directly transfer the presets and the MIDI Map from one DMV-PRO to another
one with a MIDI cable.
To perform a MIDI Dump, press the MIDI/Util button.
Turn the Preset Encoder until LCD (B) reads: [ 0$11 #(2 2- 3,. 0$1$21 : ]. When you press
the Edit (B) button, the preset information will be sent and both LCDs will read: [ 0 T1,(22(T&
  2 ]. It may take a few seconds for the operation to complete.
NOTE: Individual presets and the MIDI Map can be dumped or loaded separately if the operation is initiated
by an external MIDI device such as a sequencer or an external controller. See page 51 for more information
on the DMV-PRO’s MIDI implementation.

- 12 -
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. We don’t recommend plugging microphones directly
into the processor. Instead, either use a preamp, a mixer, or an amp’s preamp section to first boost the mic’s level,
then use the effects loop output or reverb send. High signal level from a preamp or effects loop assures an optimum
signal-to-noise ratio in the DMV-PRO, keeping hiss and distortion to a minimum.
$ POWER JACK INPUT
An external AC adapter powers the DMV-PRO. Plug the adapter into this jack and then into a power outlet.
Only use the adapter that came with the DMV-PRO. If the adapter ever becomes damaged, immediately
discontinue use.
% MIDI IN & MIDI OUT
The MIDI In jack enables you to “talk” to the DMV-PRO from an external source such as A R T’s X-11 or X-15
Ultrafoot, an outboard sequencer, or a computer equipped with MIDI ports and associated software. Use this
jack for receiving program change, continuous controller, note, and system exclusive messages.
Use the MIDI Out jack for performing a MIDI data dump. It connects to any external device capable of
recording MIDI data and allows the DMV-PRO to off-load the contents of its memory. The MIDI Out jack does
not act as a MIDI Thru, so the DMV-PRO should be placed at the end of your MIDI chain.

- 13 -
& 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.
' OUTPUT LEVEL SWITCH
The Output Level switch is used for matching the DMV-PRO’s output level to your system. Matched signal
levels are important for controlling the amount of distortion present in the final signal. Too little signal results in
a disproportionate amount of noise, while too much signal sounds distorted and gritty. The Output 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 input levels.
NOTE: The Output switch’s setting is global, meaning that it always affects the DMV-PRO’s output level,
regardless of which preset is engaged.
( INPUTS #1–4
All Inputs are single-ended (unbalanced) ¼’ jacks with high impedance. As with the Output jacks, a preset’s
routing determines the use of each Input jack. For example, Cascade and Stereo Routings do not use Inputs
#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.
If any Input (except #1) does not have a plug inserted, it will automatically take its signal from the closest,
lower-numbered, input jack that has a plug inserted. For example, if a ¼” plug is only inserted into Input #1,
then Inputs #2, #3, and #4 will also use the signal from Input #1.
) INPUT 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 DMV-PRO. 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.
NOTE: Like the Output Level switch, the Input Level switch’s setting is global, meaning that it always affects
the DMV-PRO’s input level, regardless of which preset is engaged.

TUTORIAL
The best way to understand the DMV-PRO is just to jump in and edit some presets. It doesn’t take long and
you’ll see how easy editing is due to the DMV-PRO’s intuitive layout. This section consists of four tutorials:
Starting from Scratch and Changing Effects, Editing Effect Parameters , MIDI , and Advanced Applications .
After you finish the tutorials, check out the section entitled
The DMV-PRO’s Adjustable Parameters , on page
26, for a complete list of each effect’s parameters and parameter ranges.
INTRODUCTION:
The DMV-PRO contains four DSP engines and four separate input and output channels. Typically, an engine
processes one individual channel of audio. Two engines can be combined into stereo groups with separate
audio channels and linked control parameters. Two stereo groups can be run in series to create multiple
effects and there’s even a special routing that runs two mono engines and one stereo group in series to
create even longer multi-effect chains. By the way, each engine or engine group has its own EQ and delay
section and many classes also contain a dynamics sensing section, so effect chains can actually be quite
long. Engines #1 and #2 are always controlled by the DMV-PRO’s Processor (A) section and Engines #3 and
#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. Each channel’s audio remains
independent, but the effect parameters of each group
are linked to create stereo processing. The first effect
(Inputs, Outputs, and Engines #1 and #2) is edited in
Processor (A) and the second effect (Inputs, Outputs,
and Engines #3 and #4) is edited in Processor (B).

Cascade
Cascade routing also has two effects with two
linked engines, but the output of the first group is
fed into the second. In this routing, you have two
stacked, true-stereo effects. Only Inputs and
Outputs #1 and #2 are used. The first effect
(Engines #1 and #2) is edited in Processor (A),
and the second effect (Engines #3 and #4) is
edited in Processor (B).
Discrete 4 (mono)
In Discrete 4 routing, each engine separately processes one
channel of sound and is just like having four mono effects.
Inputs and Outputs #1–4 correspond to Engines #1–4.
Engines #1 and #2 are edited in Processor (A) and Engines
#3 and #4 are edited in Processor (B).
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. Inputs and
Outputs #3 and #4 are not used. Processor (A) controls the two mono effects (Engines #1 and #2) and
Processor (B) controls the true-stereo effect group (Engines #3 and #4).
NOTE: See page 26 for more information on the DMV-PRO’s versatile routing configurations.

TUTORIAL 1: STARTING FROM SCRATCH AND CHANGING EFFECTS
Edit the Routing:
By editing any preset’s routing, you are essentially building a new preset from scratch.
When routings are changed, the DMV-PRO reconfigures its internal architecture and loads
in default effects. The preset’s former effects, class, and parameter values are all replaced.
Repeatedly press the Routing button until the Twin Stereo Routing LED is lit. If Twin Stereo
was already lit, press the Routing button a few times until it becomes lit again. Depending on the
mode that you were last in, the LCDs may initially warn you that a change of routing will erase the current
effects.
Disregard the notice; it’s exactly what we want to do!
After Twin Stereo routing has been selected, notice that both Processor LCDs are displaying the Stereo Hall
effect—this may be different from what was originally there. As mentioned, when you change routings the
DMV-PRO loads in default effects. In the case of Twin Stereo routing, the default effects are both Stereo Hall.
Don’t worry, changing effects is easy; simply turn Encoder (A) to change Processor (A)’s effect or turn
Encoder (B) to change Processor (B)’s effect. As you are scrolling through the effects, notice that all except
for Stereo Hall are flashing. The flashing is a reminder that you are not viewing the preset’s current effect, and
consequently, you will not hear what you are seeing in the LCD. When you have found the effect that you
want to hear, press the Encoder to select it and notice that it is no longer flashing. To try out more effects,
again turn the Encoder and push it to select and hear them.
Effects in the DMV-PRO are always ordered this way: Chamber, Room, Hall, Plate, Delay, Pitch, Chorus,
Flanger, Phaser, Rotary, Tremolo, and Panner. To access effects on the right side of the loaded (non-
flashing) effect, turn the Encoder to the right. To access effects on the left side, turn to the left.
Processors (A) and (B) are completely independent and can be edited at the same time. Turn and push
Encoder (B) to change Processor (B)’s effect. However, if you are only monitoring Outputs #1 and #2, you
won’t hear 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.
