Car audio is becoming indispensible for not only creating a comfortable space for the driver and passengers through music,
but for providing useful information as well. Recent years have also seen the rapid proliferation of new audio sources such
as MP3 players and USB flash memory.
ROHM provides products designed for both conventional music sources such as CDs and radio, and also easy-to-use
solutions that enable plug-and-play connectivity for the latest USB and MP3 players.
In addition, ROHM brings in analog technology that matured over many years of experience to develop high fidelity sound
processors that significantly improve the listening experience by reducing noise at low frequencies optimized for high
resolution audio sources as well as HEVs and EVs with quieter interiors that demand superior audio quality.
