The third tier in Lexicon’s award-winning MPX Series, the MPX550 offers high-end professional features and “Lexicon Sound” at an affordable price. Like its predecessors, the MPX 550 is a true stereo processor that includes 24-bit analog-to-digital and digital-to-analog conversion. It relies on the proprietary LexiChip engine to perform 24-bit internal processing. Its 255 carefully-crafted presets feature legendary Lexicon reverb, as well as dual programs that combine two independent effects in four routing configurations. Tempo can be set using audio input, a dual footswitch, the front panel Tap button, or an external MIDI device. A powerful editing tool called Learn Mode allows patching of up to five front panel controls. To this, the MPX 550 adds impressive features such as balanced analog inputs and outputs, a large front panel display, four Edit knobs for simple parameter adjustment, and an internal power supply.
