ROHM has launched a new brand "MUS-IC", which reflects ROHM's approach to solutions for Hi-Fi audio products. This brand covers a range of D/A converter integrated circuits (DAC ICs), optimized for power supply and hi-fi playback products. The increasing adoption of high-resolution audio sources has of late increased the demand for audio equipment that can deliver adequate sound quality. Audio DAC chips, which convert high-resolution digital audio data to analog without degrading the original sound source, are one of the most important components in determining the quality of audio equipment.
ROHM has state-of-the-art D/A converter technologies that are optimized for high-fidelity reproduction of high-resolution sound sources. Delivering unmatched low noise and distortion (S/N ratio and THD+N characteristics) in its class, as required by leading audio equipment manufacturers, the DAC chips have been optimized for excellent quality of sound through numerous listening tests and laboratory measurements. Leveraging 50 years of experience in the development of audio ICs, ROHM has been able to define "sound quality design technology" capabilities for high-fidelity audio reproduction that is very similar to the original sound source and therefore Therefore, offer products designed with special emphasis on sound quality, including sound processors and power supply ICs. In May 2018, ROHM presented an initial development sample of a DAC chip at the Hi-Fi Audio international fair held in Munich, Germany, where it was recognized by major audio equipment manufacturers, who showed great interest in its adoption. once its commercialization begins.
In addition to this DAC chip, ROHM also offers a product portfolio of power supply ICs (BD372xx series) and sound processors (BD3470x series, BD34602FS-M). All products optimized for hi-fi audio applications are available under its new ROHM Musical Device "MUSIC" brand of audio devices. “We have developed this range of products by combining our high-quality design technology with the corporate mission of 'Quality first', our vertically integrated manufacturing. And we are also implementing activities that contribute to the dissemination and development of music culture with the ROHM Music Foundation,” said Naruhiro Okamoto, Director of ROHM Audio Development Department. “The team of experienced engineers have developed the ultimate integrated circuit solution that is perfectly represented by the new brand of audio devices “MUS-IC”. The ROHM Musical Device “MUS-IC” website can be found at: https://www.rohm. com/mus-ic/ In the future, ROHM will strive to become a total solution provider of audio components that will contribute to the development and progress of music culture with faithful reproduction of music, all under the ROHM Musical brand.
