The Lumin project is a workalike of the BBE® Sonic Stomp / Sonic Maximizer. It’s based on work done by Bajaman (documented on FSB)[1] and Sebastian Montti (stm) on DIYStompboxes in recreating the functionality of BBE’s proprietary NJM2150AD chip.[2] The BBE 482i Sonic Maximizer rack unit first appeared on the scene in the late 1980s and quickly achieved legendary status among sound engineers for the way it imparted clarity on the signal—often described as sounding like a blanket was lifted off the speaker cabinet. The circuit is said to create “frequency-dependent time alignment” so that the audio frequencies hit the speaker in a more optimal way. Many professional audio setups even outside the music industry utilize the “BBE process” to enhance sound quality.
