Designed to extract and convert high-resolution audio data into analog signals at the highest possible level, audio DAC chips are one of the most important components in determining the quality of audio equipment. Leveraging 50 years of experience in developing audio integrated circuits, ROHM has defined a "Sound Quality Design Technology" capable of extracting all the information from sound sources and thus offering products that deliver superior sound quality, including sound processors and power management integrated circuits.
The BD34301EKV DAC chip, developed as part of ROHM's high-performance MUS-IC™ series, represents the pinnacle of audio integrated circuits, placing particular emphasis on factors such as spatial resonance, sense of scale, and stillness—qualities crucial for classical music reproduction. Original sound quality design technology enables the successful reproduction of desired sound quality by incorporating a dedicated circuit within the signal processing block to verify audio quality. Simultaneously, class-leading low noise and distortion (130 dB signal-to-noise ratio, -115 dB THD+N) delivers the high performance demanded by high-fidelity audio equipment. Finally, the customizable digital filter—a key feature of the digital signal processing circuit—allows for the creation of the ideal sound sought after by audio equipment manufacturers.
It is no surprise that the BD34301EKV was adopted for the digital circuitry of LUXMAN CORPORATION's flagship D-10X SACD/CD player, a renowned manufacturer of high-end audio equipment. Masakazu Nagatsuma, director and general manager of LUXMAN's development department, praised the BD34301EKV's performance and sound quality from the development phase: "The sound is natural and flat across all frequency bands, making it easy to listen to for extended periods."

About the LUXMAN D-10X SACD/CD Player
LUXMAN's new flagship D-10X SACD/CD player builds upon the brilliant legacy of our acclaimed D-08u, incorporating new playback capabilities, the latest conversion technology, a robust and reinforced mechanism, and a sophisticated analog output stage.
In addition to LxDTM-i (LUXMAN's original disc transport mechanism (improved)) and ODNF-u (Only Distortion Negative Feedback (ultimate)) in a fully balanced output amplifier, the heart of the digital circuitry utilizes ROHM's BD34301EKV D/A converter ICs in a dual configuration.
