MUSIC INTEGRITY ENGINE™ & DSP
KEF’s bespoke DSP (Digital Signal Processor), the Music Integrity
Engine™ is designed specifically for the LSX driver and cabinet,
allowing LSX to reproduce audio as cleanly and purely as is
expected from the LS family of products.
Each cabinet contains its own on-board DSP for precise
reproduction and control of the audio output. A precise on-board
clock controls the timing between the left and right channels,
whether in Cable Mode or when using KEF’s proprietary on-board
Wi-Fi network for complete wireless operation.
Each cabinet also contains the same audiophile-quality DAC as
found in the LS50 Wireless.
Consult the section on the KEF Control and Audio Profiles for
information on getting the highest quality audio output possible
through use of the DSP and Music Integrity Engine. (pg 19)
