Specifications - Lexicon MPX 100 Product Introduction

MPX 100 Dual Channel Processor
Stereo 44.1kHz S/PDIF Digital Output
The MPX 100 is a true stereo dual-channel procesor with 24-bit internal processing, 20-bit A/D-
D/A and S/PDIF digital output. Powered by a new version of Lexicon's proprietary Lexichip,™ the MPX
100 has 240 presets with classic, true stereo reverb programs such as Ambience, Plate, Chamber and
Inverse, as well as Tremolo, Rotary, Chorus, Flange, Pitch, Detune, 5.7 second Delay and Echo. Dual-
channel processing gives you completely independent effects on the left and right channels.
A front panel Adjust knob allows instant manipulation of each effect's critical parameters and an Effects/
Balance knob lets you control effect level or the balance of dual effect combinations. An easy Learn
mode allows MIDI patching of front panel controls. In addition, tempo-controlled delays lock to Tap or
MIDI clock, and Tap tempos can be controlled by audio input, the front panel Tap button, dual footswitch,
external MIDI controller or MIDI Program Change. Other features include dual 2-stage headroom
indicators, a headphone output, a software-selectable MIDI OUT/THRU port, pushbutton or footswitch
selection of dry or muted audio output and a 20Hz-20kHz ±1dB Frequency Response.
