(1) A feature in mixing that automatically routes one or more selected channels to the recording monitors or headphones without disturbing the main audio mix. Some studio consoles use destructive solo, where the soloed instruments replace the mix in the main stereo bus. On sound reinforcement mixing consoles, solo functions are normally routed to headphones (non-destructive solo), allowing the engineer to check console channels while the concert is in progress. In-place solo is a function that permits the user to hear individual channels, but also in the correct stereo perspective, as defined by that channel’s pan control.
(2) A section of music which gives particular prominence to one musician.
