of effects processors. The MPX 1 multi processor technology gives you multi
effects the way you expect them to work — with instant access to individual
effects, and the ability to run uncompromised stereo reverb at all times. In
addition to the superb sonic quality you expect from Lexicon, the MPX 1 gives
you easy, top level control over even the most complex functions, and visual
feedback to let you know exactly where you are and what features are available
at all times.
Six primary effect types: Pitch, Chorus, EQ, Modulation, Delay and Reverb give
you push button access to an arsenal of 57 effects. 200 presets make maximum
use of these effects in combination — using as many as 4 stereo effects in
addition to uncompromised stereo reverb.
Introduction
Effect buttons light to show you
which are active in any program.
Push any lighted effect button to
instantly bypass the effect. Press it
again to turn the effect back on.
The preset library is organized under database control to allow you to quickly
find programs designed for specific sources such as Guitar, Vocals or Live
Performance, or to find all of the programs using certain effects such as Pitch
or EQ.
Be sure to experiment with all 200 presets to get a feel for the full range of
MPX 1 capabilities.
Visual feedback is available every step of the way when you're using the
MPX 1, with lighted buttons indicating the state of the unit and alerting you to
extra features available from the front panel. A large numeric display shows
program (and patch) numbers. A second alphanumeric display shows you
program and parameter names and settings.
Like all Lexicon processors, the MPX 1 gives you as much depth of control as
you're ever likely to want, while keeping the details out of your way. Surface
control of the MPX 1 is straightforward and intuitive, with the most useful
parameters of every program available right in Program mode. In addition to this
specially designed "soft row", common functions and controls are brought right
out to the front panel for instant access.
For example, Mix and Level controls, for the entire system, or for any individual
effect, can be accessed at any time by pressing the front panel Mix button. The
front panel Patch button, which gives you similar instant access to the Patching
system, lights whenever a patched parameter is selected to remind you that you
can jump right in and out of the patching system at will.

The MPX 1 gives you tap tempo control when you want it. You can assign tempo
control to modulation rates, delay times or any effect parameter, ensuring that
your effects are in tempo with your music. Tempos can be tapped in with the front
panel Tap button (or an assigned controller) or “dialed-in”, in BPM (beats per
minute) on the display. The MPX 1 also lets you generate MIDI clock from your
tempo, as well as receive MIDI tempo from an external sequencer or drum
machine. Many presets have delay times assigned to Tap tempo. Try loading
some of these. (Select source type: Tempo in the database to find all of them.)
When you load a tempo driven program, the front panel Tempo LED will flash
at the current tempo to let you know the Tap button is active. Press Tap twice
in rhythm to change tempo.
The Tempo light will flash in tempo
whenever the Tap button is active.
Press Tap twice in rhythm to match
the tempo of effects to your music.
The A or B LED will light whenever a
program with A/B Glide is loaded.
Press A/B to activate a parameter
glide whenever these lights are lit.
Many features
are brought out under
the Options button – which
will light whenever options are
available.
An A/B glide function is also available from the front panel — and of course we've
designed presets to show this function off to its fullest. Whenever the A or B LED
is lit, press the A/B button to activate the glide.
When you want to create your own versions, you'll find A/B available as an
internal controller in Edit mode along with two LFOs, a MIDI arpeggiator, two
ADRs, Envelopes, and more.
Complete editing control is provided under the Edit button, where you can
customize presets or make new ones from scratch, design your own soft row
parameters, copy effects into new programs, and put effects in any sequence
or routing configuration you want. Easy access to all of the parameters of any
effect is just a button push away.
All of the front panel functions (Tap, A/B, Effect selection, etc.) can easily be
connected to MIDI controllers, footswitches, or footpedals, letting you set up all
of the functions the way you want them.
About the manual
We designed the MPX 1 to be simple to use, and have provided a quick reference
card to show you around the main features, but to get the most out of the MPX
1, we suggest that you invest the time to explore this manual. We think you’ll
agree that the time spent investigating will reward you with enjoyment of its full
capabilities.
To get off to a quick start, turn directly to Chapter 1 Product Overview and
Chapter 2 Basic Operation. The first section provides button definitions and
necessary information for setting audio levels and connecting to other equipment. The second will tell you everything you need to know about loading and
playing with programs.
When you want to know more, check out the Table of Contents. We've divided
topics into many easy to read (or skip) chapters so that you can find what you
need without wading through what you don't.
When the MPX 1 is left idle for any length of time, a "Sleep" mode is
activated. In this mode, a set of messages is cycled across the display.
When shipped, the Sleep mode is set to "English Promo" for display of
MPX 1 features. You can change this mode to display features in other
languages, Help messages which give you general information, or you
can turn off the messages completely. To select the mode you want:
press System. Use the knob to select Modes, then use the < and >
buttons to select Sleep. Use the knob to select Off, Help or Promo in

Product Overview
Installation Notes
The MPX 1 uses one EIA-standard rack space, and can be mounted on any
level surface or in a standard 19 inch (483 mm) rack. If the unit is mounted in a
rack or road case, support the rear of the chassis to prevent possible damage
from mechanical shock and vibration.
The maximum ambient operating temperature is 104°F (40°C). Provide adequate ventilation if the unit is mounted in a closed rack with heat-producing
equipment such as power amplifiers.
The MPX 1 is equipped with a 3-pin IEC power connector and detachable cord.
The unit will operate with power sources from 100 to 240 volts AC, 50-60Hz.
Power switching to actual line voltage is automatic.
Analog Audio
For best performance, maintain balanced connections, and use high-quality,
low-capacitance, twisted-shielded pair cable.
When connecting MPX 1 outputs to single-ended, unbalanced devices, leave
the low side floating and connect the grounds between the units.
Digital Audio
Connectors are provided for S/PDIF (CP-340 Type II) Consumer Digital Audio
I/O. 75Ω coaxial cable suited for digital audio or video signals is required. Audio
grade cable is not suitable. Only 44.1kHz signals are recognized.

Mono Applications: Using the MPX 1 Inputs with a Mono Source
Many of the programs in the MPX 1 are designed to process stereo input signals.
These programs will also work and sound great with mono signals - but you need
to configure the unit for mono. It will not automatically compensate for single-wire
mono input connections.
There are two ways to use the MPX 1 in an installation where its inputs will be
driven from a single, mono source:
• Use a Y-connector to send the signal to both inputs.
• Connect the mono signal to either the Left or Right input connector, then
change the System mode Audio Input Mode parameter. If the Left input is
connected, change the setting to Mono (L only). If the Right input is
connected, change it to Mono (R only). The Mono settings of this parameter
apply to the S/PDIF digital inputs as well. This allows you to select either the
left or the right digital channel for processing.
NOTE
Individual programs can be optimized for mono input by simply inserting a mono
effect, such as Volume (M), into the first block of the routing map. See Chapter
3: Editing for more information on routing. See Chapter 7: The Effects and
Parameters for more information on individual effects.
1-3
LexiconMPX 1 User Guide
Mono Applications: Using the MPX 1 Outputs with Mono Return
Virtually all of the MPX 1 programs generate stereo or dual output signals, even
when driven by a mono source. For the best sonic results, the MPX 1 outputs
should be connected in stereo. If you are using the MPX 1 in a mono system with
only a single input, use a simple 2 x 1 mixer or a Y-connector to combine both
outputs.
NOTE
Individual programs can be optimized for mono input by simply inserting a mono
effect, such as Volume (M), into the last block of the routing map. See Chapter
3: Editing for more information on routing. See Chapter 7: The Effects and
Parameters for more information on individual effects.
Be careful to keep input and output to all channels wired consistently. Outof-phase wiring can produce audible effects.
Footswitch/Footpedal
One 1/4 inch T/R/S phone jack is provided for 3 momentary footswitches.
Another 1/4 inch T/R/S phone jack is provided for a footpedal (minimum 10k to
maximum 100k impedance). Normally open or normally closed momentary
switches are suitable. At power on, the MPX 1 assumes the switch is off. Use
shielded, twisted-pair cable with shield connected to sleeve. See diagram on
previous page. See also Chapter 5: System Controls for information on pedal
calibration.
Setting Audio Levels
MIDI
5-pin DIN connectors are provided for MIDI THRU and OUT. A 7-pin DIN
connector is provided for MIDI IN or a powered remote. Use standard MIDI cable
assemblies, available from your local dealer.
The MPX 1, with both analog and digital input and output connections, requires
some attention to proper setting of signal level.
Analog inputs are first gain-conditioned by the rear panel input level switch, and
then by the front panel Input knob. Proper setting of both the switch and knob
are important for best performance of the A/D converter.
Analog and digital sources are selected in System mode on the Input/Clck
screen of the Audio menu. The selections are: Analog/Int, Analog/Ext and
Dig/Ext.
Proper setting of Input level is dependent on:
• Proper signal level into the analog front end to avoid signals causing overload
at the Digital Signal Processing (DSP) input (rear panel Input button)
• Proper adjustment of the signal level into the analog-to-digital converter to
optimize noise and avoid overload (front panel Input knob)
• Proper setting of signal level within the digital signal processor to optimize
noise (Lvl parameter in each effect block)
1-4
Digital input level is adjustable from the Dig In Lvl screen of the Audio menu in
System mode. Level can be set to Off, -89dB to +6db to optimize noise and
avoid overload.
Headroom Display
The headroom display provides both headroom and overload information from
a variety of measurement points.
The information on the headroom display is selectable from the Meters Assign
menu in Edit mode and the assignment made here is saved as a part of each
program. The available assignments are:
Inputs
Outputs
InLevel, OutLevel or In&OutLevel for all effect blocks. (when In&Out is
selected, the left side of the headroom display will display InLevel and
the right side of the headroom display will display OutLevel.)
LFO 1 and LFO 2 (Left and right sides of the display)
Envelope 1 and Envelope 2 (Left and right sides of the display)
Footpedal
ADR 1 and ADR 2 (Left and right sides of the display)
Simulation display (for test purposes)
Product Overview
Rear Panel Input Level Switch
The chart below illustrates the adjustment range that will set input levels for both
balanced and unbalanced operation.When a choice can be made, it is best to
operate at the higher amplitude end of the recommended range to optimize
noise performance.
Unbalanced (-10) Balanced (+4)
overload: > +8dBu >+20dBu
acceptable: 8dBu to -14dBu +20dBu to -2dBu
too low (noisy): <-14dBu <-2dBu
Overload
The Clip (overload) indicators will light under the following conditions:
• Analog-to-Digital (A/D) overload
• overload at any point in effects processing within .1dB of maximum
• input level within .1dB of maximum
For example, internal peaking of high Q filters, or level buildup from certain
reverberation modes can result in overload, even when the input A/D or digital
receiver data stream is not at full scale. Such conditions are most often caused
by a combination of extreme parameter settings. Adjusting parameter/level
settings can eliminate these overload conditions.

LexiconMPX 1 User Guide
Setting the Input Mode
The MPX 1 can be set for stereo input, mono left input or mono right input. To
set the mode, press System, select Audio, then select Input Mode. If cables
are connected to both XLR and 1/4" connectors, the 1/4" inputs will override and
disable the XLR inputs. Selecting either Mono setting routes the selected audio
input channel (left or right) to both left and right DSP signal paths. (This is true
for both digital and analog inputs.)
Using Soft Sat
Soft Sat is a built-in analog limiter that precedes the A/D converters in the
MPX 1. If the source to the MPX 1 is “hot”, you can use Soft Sat to reduce the
harshness caused by overloading the A/D converters. Press System, select the
Audio menu, then select Soft Sat to turn the limiter On or Off.
Setting Input Level
1. Set the rear panel Input button to the appropriate position for balanced or
unbalanced operation.
2. Press Edit and scroll to the Meters Assign parameter. Make sure that the
meter assignment is Input (the default setting).
3. Press System.
4. Select the Audio menu and scroll to the Input/Clck screen.
5. Select the desired input mode.
6. If you have selected Analog/Int or Analog/Ext, run audio through the unit
and adjust the front panel Input knob so that program material peaks cause
the headroom display to reach the top of the column without lighting the Clip
indicators. An occasional peak which momentarily lights the Clip indicators
is acceptable in most instances, but should be validated by listening to the
actual result. If the the 0dB headroom indicator illuminates frequently, you
may want to use the Soft Sat limiter to reduce overload of the A/D converters.
Press System, select the Audio menu, then select Soft Sat to turn the limiter
On or Off.
If you have selected Dig/Ext, scroll to the Audio Dig In Lvl screen and adjust
the level so that program material peaks cause the headroom display to
reach the top of the LED column without ever lighting the Clip indicators.
The meters are calibrated to light the Clip indicators at a level of > 0.1dBfs.
For digital inputs, a very brief flashing of the Clip indicators means that you
have reached, or are dangerously close to digital clipping.

Setting Output Level
1. Press System and select the Audio menu.
2. Scroll to Audio Output and select Analog or Digital.
3. Press System again and select the Modes menu.
4. Scroll to Modes: Bypass and make sure that the assignment is Bypass (the
default setting).
5. Press the front panel Bypass button. The button will light to indicate that
bypass is engaged.
6. Press Edit, scroll to Meters Assign and select Output.
7. Run audio through the unit and use the front panel Output knob to set the
level on your console or amplifier.
The signal level from the 1/4" and XLR outputs is +4dBu. If you have both 1/4"
and XLR cables attached to the output connectors, there will be no change in
level unless you are driving very low impedance loads (600Ω), where an
attenuation of output level may occur.

If you will be using the MPX 1 as your primary effects unit, and your system
includes a console with one or more auxiliary (effects) sends, connect the units
as shown above.
Use channel inserts or prefader sends for best results with programs that are not
delay-based or reverb-based (Rotary Cab, Telephone, GuitarCabEQ etc.).
In most applications, it is preferable to connect the MPX 1 outputs to two of the
console's input channel strips, panned full left and right, rather than to the effects
returns. This allows the greatest flexibility in routing and equalization.
In this configuration the console controls are used to set the amount of effect
heard—the MPX 1 Mstr Mix control should be set to 100%.

Tap
Flashing of the Tempo LED indicates that Tap is active. Press Tap
twice in rhythm to change the tempo
of delay or modulation parameters
in the current program.
A/B
MPX 1 tempo controls are available right on the front panel through the Tempo
LED and the Tap button. Many preset programs are designed with their own
tempo rate settings which are stored with the programs. The front panel Tempo
LED will flash in tempo whenever you load a program with tempo control. This
flashing indicates that the Tap button is active, allowing you to change tempo on
the fly. Whenever you see the Tempo light flashing, simply press Tap twice in
rhythm to establish the rate you want.
You can override these individual tempo rates with a global tempo rate in the
System Setup menu. Tempo is also available as an independent patch source
which can control any effect parameter. (See Chapter 4: Patching and Chapter
5: System Controls.)
A/B is a unique glide function which allows you to morph between selected
parameters. Most effect parameters (or groups of parameters) can be patched
to the A/B controller. Once a parameter is patched, the A/B controls in Edit mode
allow you to select the rate at which you want to glide from A to B and from B to
A when the front panel A/B button is pressed. You can also assign the glide
function to be triggered by any internal source, such as input level, or by an
internal or external controller.
When A is lit, pressing the A/B button activates a parameter glide.
Pressing A/B again reverses the
glide.
Many of the presets are designed with A/B patches that allow you to morph
between two effects, glide from slow to fast rotary speakers, start and stop loop
delays, etc. Loading any program with A/B control assigned, will cause the front
panel A LED to light, indicating that the A/B function is active. Press A/B to
activate a glide from the parameter values assigned to A to the parameter values
assigned to B. Press A/B again to glide back to the A parameter values. (When
you want to change the A/B parameters, control A/B remotely, assign a trigger
source, or alter the rate of glide, refer to Chapter 4: Patching and Chapter 8:

the knob will scroll through the programs in the first of the categories listed in
parenthesis above. The < and > buttons will jump to the next sorting category.
When you select source&effect and return to Program mode, the < button will
select source types, the > button will select effect types, and the knob will scroll
through any programs which fit into the two categories selected.
Assigning source and effect types to programs is done in a database menu in
Edit Mode.
Basic Operation
Once you've made changes to a program, such as turning an effect off, or
modifying any of the soft row parameters, an edit indicator in the display (•) will
appear in front of the program name. This identifies the program as having been
altered since the last store procedure. This edit indicator, along with all of your
changes, will disappear when you load another program.
To save your changes, press Store. The LED in the Store button will flash to let
you know you are in the middle of a store procedure and the display will show:
Program Name
201 available
The upper line of the display shows the name of the currently running program.
The lower line shows a user program number (201-250) and the name of the
program currently stored there. (When the MPX 1 is shipped, the user programs
are all "available".)
The < and > buttons move an underbar cursor in the display from the program
number to each letter of the current name. Turning the knob will select another
program number, or will select alphanumeric characters when the cursor is in the
upper line of the display.
Once you've made changes to the program name or selected a new location for
it, press Store again. The display will show:
Program Store
Press Store to
initiate the store
procedure.
The Store LED will
flash while you
change the name of
the program and decide where to store it.
Press the flashing Store button
to verify your changes.
Are you sure?
Yes or No
The numeric display will flash the user program number you have selected while
you decide to press > Yes or < No. Once you have stored your program, it will
automatically be added to the database and you will return to Program Load
mode.
NOTE: If the stored program no longer meets the DataBase sorting criteria of the
original version, the MPX 1 will automatically switch the DataBase setting to
"Sort by number".
Press Yes to complete the store.

Editing
3
This chapter describes all of the MPX 1 edit functions. As the first thing you are
likely to want to modify in a program are its effects, this section starts there and
then moves on to all of the functions available in Edit mode.
Note that, in Edit mode, as elsewhere, the Value button acts as a toggle to allow
you to assign "select" and "adjust" functions to either the knob or the < and >
buttons, whichever is most convenient. As the default state of the Value button
is On (lit) in Edit mode, any step by step instructions given in this section will
assume this state.
Editing
When Value is lit, the < and >
buttons select parameters, and
the knob adjusts the value of the
selected parameter.
Effect Editing
To edit any effect, press Edit, then press an Effect button to view all of the Effects
of that type, and to edit the parameters of the current Effect. The display will show
the Effect type and the name of the currently loaded Effect . Turn the knob to view
other Effects of the displayed type.
If you load a new Effect, an edit indicator will be
displayed to show that the current program has
been modified.
EQ . select:
> ✱ Effect Name
The Effect name will be marked with an asterisk (✱) and the Effect button light
will blink rapidly if the displayed effect can be loaded in the current program.
(Press and hold the Effect button to display the name of the Effect currently in
use.)
3-1
LexiconMPX 1 User Guide
To load any available Effect, press the Effect button again. The asterisk will
disappear from the displayed name and the button light will return to its normal
slow blinking edit state. An edit indicator is displayed to indicate that the active
program has been modified.
Coarse and Fine Editing
of ms and Hz values
Parameters whose values are displayed in ms or Hz have overall
ranges of more than 1000 units.
When you select one of these parameters for editing, you’ll notice
that either the left or right portions of
the value can be selected for editing.
For quick, coarse adjustments, select the left portion of the value. For
fine adjustments, select the right
portion of the value. The fine and
coarse increments for each type of
parameter are:
ms (delay times)
coarse increments=100 ms
fine increments=1ms
Hz (LFO rates)
coarse increments=1 Hz
fine increments=.01Hz
Hz (EQ Fc)
coarse increments=100 Hz
fine increments=1Hz
To edit the parameters of the current effect, press > . The display will show one
or more parameters as shown below.
One or two parameters will be shown on each parameter
screen. An edit indicator appears in front of the parameter name
if the value has been changed since the last store operation.
The Effect type is
shown in the upper
left of the display.
EQ Fc .Gain1
< > 2500 -5 dB
Fields which are selected for changing will blink.
Parameter values
are shown on the
bottom line of the
display.
The item on the lower line of the display which is selected for adjustment will
flash. Turn the knob to scroll through the entire range of parameter values. Use
the < and > buttons to select another parameter value field and to move to
another parameter screen.
Detailed information on each Effect and its parameters is provided in Chapter 7.
