Augment conventional directional PA with a Differential Mode sphere emitter, so the audience receives the direct and room components of the program at once – in controlled proportion, as captured or as extracted.
The chain, crystallized for the venue
A touring or installed rig keeps its directional boxes aimed at the crowd. Alongside them, an M.A. sphere emitter radiates the Differential Mode into the venue, so the room cooperates with the program instead of fighting it.
The directional system keeps carrying the direct sound to the audience.
Twelve free-radiating drivers on a pentagonal-dodecahedron frame carry the Differential Mode at venue scale – a reference cabinet combines sub, direct and room emission in one column.
Native M.A. capture, correlation-extracted Differential Mode from stereo/multichannel, or difference-derived DM from the L/R console buses.
The emitted differential mode from the M.A. Sphere can help to mask the effects of "slapback" in a room from the conventional sound reinforcement.
