The MPX 200 is a true stereo, dual channel processor. It combines the best of the MPX 100 with several new features providing an advanced level of operation. It includes 24-bit internal processing, S/PDIF input and output, and LexiconÆs exclusive LexichipÖ engine. Add to this 24-bit A/D-D/A, a new digital compressor, extensive front panel parameter LEDs, internal power supply, and an expanded User Bank capable of storing 64 user programs. It offers 240 presets with classic Lexicon reverb, as well as Chorus, up to 5.5 second Delay, Detune, Echo, Flange, Pitch, Rotary, and Tremolo. Dual channel processing provides two independent effects in an assortment of configurations including Cascade, Dual Mono, Dual Stereo, and Mono Split. The digital compressor is available in all 240 presets, simultaneously providing up to two effects and compression. The front panel Adjust knob allows for instant manipulation of critical parameters. As many as four program and four compression parameters are available for each program. Front panel parameter LEDs indicate which parameter is being displayed and adjusted. The front panel also features an easy access compressor button that provides simple control over the presence of the compressor in any program. Tempo can be controlled by audio input, footswitch, the front panel Tap button, an external MIDI controller, or MIDI Program change. The MPX 200 offers a full range of MIDI controls such as Program Change, MIDI bulk dump, and an easy Learn mode that allows MIDI patching of up to five front panel controls. Other features include 3-stage headroom indicators, 4-stage compression indicators, a headphone output, a software selectable MIDI OUT/THRU port, cue program mode, and pushbutton or footswitch selection of dry or muted audio output.
Extended information The MPX 200 features a front panel Adjust knob that can be used for selecting, editing, and cuing programs. Effects and Routing LEDs indicate which effects are selected, and for dual-effects programs, which routing is selected. An Edit Parameter Display indicates which parameter is selected for editing. In many cases, the Adjust knob controls several effect parameters at once to provide simple control of related parameters. For example, in many Chamber and Room programs, Adjust controls the "liveness" of space by changing decay, EQ, and early reflections simultaneously. The MPX 200Æs Cue Program Mode is accessed via the Adjust knob. Effects and Routing LEDs indicate which program is currently running, while the Load button remains lit to indicate that another program is ready for loading. Push the load button to activate the cued program.
Dual Programs
Dual programs combine either a Delay or a Reverb algorithm with a Flange, Pitch, or Chorus algorithm, or with each other. The Effects Lvl/Bal parameter
controls the relative balance of each effect within the combination. The dual
programs use four routing configurations: Cascade, Dual Mono, Dual Stereo, and Mono Split.
Tap Tempo
Tap Tempo allows the user to match delay times and modulation rates with those of the music. Whenever the tempo feature is active in a program, the green Tap LED flashes. To lock the delay or effect to the tempo, just press the Tap button twice in time with the music. Tap can also be set from any MIDI device using Continuous Controllers or program change for manual Tap or MIDI Clock for automatic synchronization. Audio input can be used to set the tempo of delay and modulation times û a necessity for live performances.
MIDI Learn
Like the MPX 100, the MPX 200 features a Learn Mode in which it can "learn" Program Change and Continuous Controller messages. This allows for remote control of front panel parameters, including Adjust, Bypass, Compressor, EQ, Lvl/Bal, Mix, and Tap. Musicians need never touch the front panel during a live performance. In the studio, controls can be automated with MIDI and recorded into any sequencing software for complete automation of MPX 200 effects.

Technical specifications Legendary Lexicon reverb is well represented with classic Ambience, Chamber, Gate, Hall, Plate, and Room algorithms that recreate the acoustics of reverberant spaces.
Tremolo programs offer numerous tremolo shapes, such as square, sawtooth, triangle, sine, and rectified sine. Since the tremolo rates can be set with Tap, it is simple to match the tempo of the music. The Adjust knob (phase) lets you set left and right channel waveforms out-of-phase, resulting in a panning motion.
The Rotary effect is a detailed simulation of a Leslie-style cabinet. Like the physical model, the high (horn) and low (drum) frequencies are "spun" in opposite directions.
Descended from the award-winning PCM series, the Chorus effect uses six independently randomized delay voices panned across the stereo field to create a rich, airy effect that simulates the sound of multiple sources from a single source, stunning on an acoustic or clean electric guitar.
Flange features two 2-Tap delays (one per channel). The first tap is fixed while the second sweeps past it. Mixing the two tap delays together creates characteristic swishing, tunneling, and fading sounds.
Detune effects have one pair of voices per channel. As more detune is applied via the Adjust knob, the pair grow more out of tune û providing a lush sound without the need for a dry signal. This is a great alternative to the Chorus effect, adding the richness of chorus without the audible sweep caused by the chorus rate.
Pitch programs allow complete program material or monophonic sources to be shifted within a range of two octaves down and one octave up.
Delays and Echoes are effects that repeat a sound a short time after it first occurs. Variations include mono (5.5 seconds), stereo (2.7s), and 6-voice multitap effects. Each of these programs can be used for digital delay or tape echo effects.
Special FX include Infinite Reverb, The Abyss, Jet Flange, Chorus Verb, Rotary Delay, LowRumble, Echoes: Beats, Stereo Stage, Dream Sequence, and Infinite Delay.
Compressor
The MPX 200 features a digital compressor that acts as a stand-alone control to modulate the level feeding other active effects. It works in front of, and in
addition to, other effects. The compressor can be used to subtly reduce volume changes to allow quieter passages in program material to be made louder, or to set limits that prevent volume from exceeding a certain level. The compressor is available in any program, situated in front of any other effects in the wet component signal path. (It has no effect on the dry signal coming out of the Mix control or the Bypass signal when Bypass Mode is set to dry.) If compression is included in a program, the Compressor Effect LED lights. Still, the compressor can be turned on or off via the easy-to-access Compressor button on the front panel, and can be set to Program or Global mode.
