Music is emotion. Perfect music reproduction relies on knowing what evokes those emotions. In 1996, Johannes Siegler, chief developer and partner at Backes&Müller, developed and successfully marketed the world's first loudspeaker with digital signal processing. These and more Today, B&M innovations establish the reference status of the BMLine series loudspeakers

The B&M DMC(TM) technology

In the bass, B&M's own DMC™ control, which has been further developed and patented, achieves the same exact music reproduction in an analogue way as the signal processor in the upper frequency band. The combination of digital signal processing in conjunction with B&M's own analog DMC™ control results in an exact linearization in magnitude and phase. The BMLine thus has a constant phase curve of zero degrees, or to put it musically: all frequencies reach the listener's ear at the same time. The result is an unbelievably true-to-impulse reproduction in connection with an exact spatial representation of the stage and the panorama, the listener is thus right in the middle of the musical event.
