Owner's Manual

Fig.6 illustrates the difference between the traditional calibration methods and AMC.
Although the microphone is not at the listening location (sweet spot), AMC can still collect
acoustical information to correct the conditions of the room environment. After processing with
the microphone signal, it transforms to a response of loudspeaker-room system. AMC measures
the arrival times of the room reflections. Each room reflection arrives at the microphone on
different times and then are separated, classified and analyzed. Then, the reflections are
reconstructed to estimate the surround sound performance at a specific listening area. Although
its target is an estimated result, it is a practical approximation derived from the sizes of typical
consumers’ home theater. Finally, AMC uses a set of filters to correct the loudspeaker EQ, so the
soundbar sound performance can be consistent, without the dependence on the room.
