Valuable information on MM 550-X Valuable information on MM 550-X SRS WOW HD Remarkable enhancement for mono and stereo playback SRS WOW HD improves the dynamic audio performance of compressed and uncompressed audio by expanding the size of the audio image and creating a deep, rich bass response. The patented techniques in SRS WOW HD widen the horizontal sound field and raise the vertical sound image, retrieving information lost in the mixing process to create a more natural audio experience.
Valuable information on MM 550-X apt-X audio coding Outstanding audio quality apt-X technology is what wireless audio has been waiting for. With apt-X audio coding, you can be assured of crisp, pure and full stereo sound. It allows you to not only hear, but experience and feel the audio as it was intended. Utilizing apt-X, Bluetooth can now offer wireless audio quality that is indistinguishable from the highest quality wired connection.
Valuable information on MM 550-X apt-X key features: 28 | MM 550-X • Blind listening tests with industry reference audiences have shown that apt-X over Bluetooth is indistinguishable from audio delivered over wired technology. Unlike psychoacoustic-based technologies such as MP3 or AAC, apt-X can be used to transport audio without degrading the audio quality. With MPEG/AAC compression, the encoding process is destructive and content perceived as “irrelevant” is discarded.
