Lexicon MPX100

soundonsound.com

The Lexicon MPX100 impresses as a budget-friendly effects processor, offering high-quality reverb and various effects with its new Lexichip III engine. Its 20-bit converters and S/PDIF output deliver impressive sound quality, making it a great choice for project studios. The unit is easy to use, despite limited user memory and editing capabilities. While the lack of balanced connections and reliance on an external power supply could deter some professionals, the MPX100's rich reverb algorithms and versatile effects are hard to match at this price point. A solid contender for both beginners and seasoned users seeking a reliable second unit.
