Two sound fields. One performance. Every M.A. system pairs two emission characteristics – a directional path aimed at the listener and a room-energizing path radiating the Differential Mode – kept separate from input to driver.
M.A. Playback
One acoustic principle, many form factors. The direct and room paths are never collapsed into a single mix bus – the high-directivity signal is rendered only by the high-directivity arrangement, and the low-directivity signal only by the low-directivity arrangement, at the same time.
Directional emission aimed at the audience carries the direct sound, exactly as a conventional system would.
An M.A. room-energizing path radiates the rotational field – at concert scale, the dodecahedron sphere emitter: twelve free-radiating drivers on a pentagonal-dodecahedron frame.
The Differential Mode is phase-split across a closely spaced mid-driver pair; spectral interlacing in the low range prevents the two phase-shifted signals from cancelling in the air.
A granted, long-dated transducer adds Differential Mode emission to otherwise conventional loudspeakers.
One principle, four markets
