I have one of these units left. The 2nd unit in the picture is still for sale. These are great workhorse units. Will consider a deal on both. Asking $225.00. The following info describes the specs for the units. Sale is for the continental US only.
The Lexicon MPX 550 is a dual-channel, 24-bit stereo processor with 255 presets and 64 user programs, featuring legendary Lexicon reverb and effects like delay, chorus, and pitch. It offers analog (XLR and 1/4") and S/PDIF digital I/O, a built-in compressor, and a large front-panel display with four Edit knobs. It supports both 44.1kHz and 48kHz sample rates and includes MIDI control and Tap Tempo.
