Tonelux Audio was founded in 2005 by engineer Paul Wolff (of Wolff Audio) to create high-quality modular mixing consoles, summing systems, and analogue processors that deliver the warmth and character of vintage gear with the flexibility demanded by modern workflows. Known for products like the VRack modules, OTB16 summing mixer, and 500-Series units, Tonelux quickly became respected for its sonic clarity, intuitive design, and rugged build. In 2010 the brand was acquired by PMI Audio Group, ensuring broader distribution while retaining Wolff’s design ethos.
