This used MPX100 is fully functional and in good condition.
The MPX 100 is a true stereo dual-channel processor with 24-bit internal processing, 20-bit A/DD/A and S/PDIF digital output. Powered by a new version of Lexicon’s proprietary Lexichip,™ the MPX100 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.
