ABOUT THE MPX 110

Thank you for purchasing the MPX 110 Dual Channel
Processor, featuring Lexicon’s proprietary Lexichip®.

The MPX 110 is a true stereo, dual-channel processor
with 24-bit internal processing, analog-to-digital
conversion, and digital-to-analog conversion. It offers
240 presets with classic Lexicon reverbs, including Plate,
Chamber, Ambience, Tremolo, Rotary, Chorus, Flange,
Pitch, Detune, 5.7 second Delay, Echo, and Inverse.
Dual-channel processing creates two independent
effects in combinations such as Dual Stereo (Parallel),
Cascade, Mono Split, and Dual Mono.

The front panel Adjust knob allows instant manipulation
of critical preset parameters, and the Effects Lvl/Bal knob
controls effect level in SINGLE programs or effect
balance in DUAL programs. All programs can be selected
with the PROGRAM and VARIATION knobs. The
PROGRAM knob selects SINGLE, DUAL, or User
programs, while the VARIATION knob selects among 16
program variations.

Tap Tempo simplifies the once-complicated process of
matching delay times and modulation rates between
tempo-based presets and other music. Tempo-controlled
delays and modulation rates lock to Tap or MIDI clock. In
addition, Tap can be controlled using audio input, a dual
footswitch, the front panel Tap button, or an external
MIDI controller using MIDI Continuous Controller or
Program Change messages.

The MPX 110 features Learn Mode, a powerful editing
tool that allows MIDI patching of five front panel
controls. Standard Continuous Controller and Program
Change messages provide complete control over Bypass,
Effects Lvl/Bal, Mix, Tap, and even Adjust.

CONNECTING THE UNIT

The INPUT and OUTPUT connectors on the MPX 110 are
1/4 inch unbalanced sockets. Connections should be
made utilizing high-quality shielded cables with 1/4 inch
Tip/Sleeve phone plugs at the end connected to the unit.

The unit produces effects from either mono or stereo
sources. For mono sources, use the RIGHT (MONO)
INPUT. For instruments and stereo sources, use both
inputs. It is recommended to use stereo outputs
whenever stereo inputs are used. Use the RIGHT
(MONO) OUTPUT if mono output is required. The left
and right input signals are combined internally when
only the RIGHT (MONO) OUTPUT is used.

HEADPHONES

The LEFT (PHONES) OUTPUT supplies a stereo signal
adequate to drive headphones, provided no connections
are made at the RIGHT (MONO) OUTPUT. This feature is
included for convenience and practice purposes. It is
intended to provide modest volume.

FOOTSWITCH

A footswitch connected to the rear panel FOOTSWITCH
connector can be used to control front panel Tap and
Bypass functions. A momentary footswitch can be wired
to a Tip/Ring/Sleeve connector or a stereo Y-connector,
which allows two identical switches to be used.

Note:

Power off the unit prior to connecting the
footswitch. Otherwise, Bypass functions will be
enabled.

Dual-Function Footswitch

A dual-function footswitch with
labels to indicate Tap and Bypass
functions is available at Lexicon
dealers or www.lexicon.com.

Getting Started

The MPX 110 can be used as two independent effects
processors with DUAL program variations 11 to 16.
Designate two auxiliary sends on the console. Connect
these to the unit - one to the LEFT INPUT and the other
to the RIGHT (MONO) INPUT. See Section 4 to take
advantage of this configuration.

SETTING AUDIO LEVELS

1. Begin with the Input knob set to the 9 o’clock
position.

2. Set the instrument or effects sends to a modest
output level.

3. Begin playing or sending audio to the MPX 110. The
Level LEDs should light green. If the Clip LEDs light
red, reduce the output level of the instrument or
effects sends until the Clip LEDs do not light during
the loudest passages.

4. Continue to play or send audio to the MPX 110.
Gradually increase the Input knob setting until the
Clip LEDs light red on the loudest passages.

5. Set the Mix knob to Dry.

6. Set the Output knob to the desired level.

7. If utilizing console sends and returns, set the Mix
knob to Wet. If utilizing an instrument amplifier, set
the Mix knob to the 12 o’clock position.

The Level LEDs do not light when the incoming signal is
more than 30dB below overload. The Clip LEDs light red
when the signal approaches overload (-2.5dB). When an
acceptable signal is present, the Level LEDs light green
almost continuously and the Clip LEDs flash red on the
loudest passages.

Note:

As with all audio products, it is good practice to first
power on all outboard equipment, then the mixer,
then the speakers.

ADJUST

The Adjust knob has been customized for
each individual program, and in most
cases controls several parameters at once
to handle complicated editing processes.
For instance, Adjust controls the

“liveness” of space in many Chamber and
Room programs by changing decay, EQ, and early
reflections simultaneously.

The behavior of the Adjust knob is also customized for
different functions:

• It can act as a linear control, at its

minimum value when set to the 7
o’clock position and its maximum
value when set to the 5 o’clock
position.

• It can act as a bipolar control, at its

minimum value when set to the 12
o’clock position, like a cut/boost EQ
control.

SELECTING PROGRAMS

All programs can be selected with the front panel
PROGRAM and VARIATION knobs. The PROGRAM knob
selects either a SINGLE, DUAL, or User program. SINGLE
program selections are arranged around the left side of
the knob; DUAL and User program selections are
arranged around the right side of the knob. The
VARIATION knob selects among 16 program variations,
arranged around the knob.

SINGLE PROGRAMS

When the PROGRAM knob is set to a SINGLE program:

• VARIATION knob settings 1 to 8 will load eight
variations of the first effect.

• VARIATION knob settings 9 to 16 will load eight

+–

variations of the second effect.

DUAL PROGRAMS

When the PROGRAM knob is set to a DUAL program:

• VARIATION knob settings 1 to 16 load 16
different program variations. Each program
contains both effects.

• See pages 4-20 to 4-35 for more information about
DUAL programs.

USER PROGRAMS

When the PROGRAM knob is set to User:

• VARIATION knob settings 1 to 16 will each load one
memory location available for storing User
programs. When shipped, these locations will
contain duplicates of presets.

• See page 4-38 for more information about User
programs.

EDITING PROGRAMS

The front panel Adjust and Effects Lvl/Bal knobs can both
be used to edit programs. The Adjust knob provides
instant manipulation of critical program parameters.
These parameters are arranged under the knob, meaning
that just one turn is all that is required to customize a
program to personal taste. The Effects Lvl/Bal knob can
be used to control effect level in SINGLE programs, or
effect balance in DUAL programs.

The unit recognizes changes made with either knob as
edits. When edits are made, the front panel Edit LED will
light to indicate that the selected program has been
modified but not stored.

Use the Adjust knob to edit the
selected program, and the Effects
Lvl/Bal knob to control effect level in
SINGLE programs or effect balance
in DUAL Programs. The Edit LED will
light to indicate that the selected
program has been modified from its
stored condition.

STORING PROGRAMS

To store a program in a User memory location:

1. Press the Store button. The Store LED will
flash slowly to indicate that the store
function is activated.

2. To continue saving the program, set the PROGRAM
knob to User. To cancel the store function without
saving the program, make sure the PROGRAM knob
is not set to User, then press the Store button again.

3. Set the VARIATION knob to select one of the 16 User
memory locations.

4. Press the Store button to save the program to the
selected location. The Store LED will flash quickly
until the store process is complete. The Edit LED will
no longer be lit when the saved version becomes the
selected program.

CAUTION

When new programs are stored in a User memory
location, programs that were previously stored at that
location will be automatically replaced.

TAP TEMPO

VARYING RHYTHM

Tap Tempo can be used to match the delay
times and modulation rates of tempo-based
programs with those of the music. The Tap LED
will flash whenever a tempo-based preset is loaded. To
set tempo from the front panel, press the Tap button
twice in time with the music. It is not required to enter
what could be the delay time in milliseconds. Just press
the Tap button twice, and the unit will calculate the
appropriate delay time. To change tempo, press the Tap
button twice again in the new rhythm. Changes made to
tempo with the Tap button are not considered program
edits, and will not cause the Edit LED to light.

AUDIO TAP

To use audio input to set tempo:

1. Press and hold the Tap button for 2

seconds. (The optional dual footswitch
allows the musician to remain in contact
with the instrument while pressing and holding the
Tap button.)

2. While holding the Tap button, play two short notes

in rhythm, then release the Tap button. The unit will
automatically calculate tempo based on the time
lapse between the two notes.

Audio tap is a must for live performances. It offers a
simple method of setting delay times and modulation
rates to match the music.

GLOBAL TEMPO

Most factory presets are stored with individual tempo
rates, which can be customized to suit personal taste.
Tap in the new tempo, then store the modified version of
the preset in a User memory location (see page 2-4).

To recall the tempo rate stored with each program, set
the System Mode parameter Tempo to Program. The
unit will apply the individual tempo setting of each
program as it is loaded. To apply the current tempo rate
to all programs, set the System Mode parameter Tempo
to Global. The unit will ignore individual tempo settings
and apply the current tempo setting to each program as
it is loaded. (The Tap LED will flash when a tempo­controlled program is loaded.)

BYPASS

The Bypass button can be used to mute audio
or to force the unit to pass only dry,
unprocessed audio. Its function depends on the
setting of the System Mode parameter Bypass. When set
to Bypass Dry, the unit sends only dry, unprocessed
audio to the outputs. When set to Mute Input, the unit
mutes the inputs only. Running effects will continue their
natural decay. Bypass functions can also be activated
with a footswitch or MIDI control device (see pages 1-8
and 5-5).

When pressed and held for 2 seconds, the Bypass button
also activates System Mode. (See Section 3 for more
information about System Mode.)
