The AK4497 is a new generation premium 32-bit DAC based on AKM’s VELVET SOUND architecture that has been widely adopted by well-established high-end audio companies. High signal to noise performance is achieved by improving VELVET SOUND technology by supporting a larger current drive capability. The performance of an audio DAC using switched capacitor is expanded to the limit with the AK4497. In addition, AKM has developed an original process that has greatly improved low noise performance and electric margin for audio devices, increasing data amount and enhancing original acoustic sound that can be found in the sound strength. 

● Dynamic Sound Playback with Large Amount of Playback Information: VELVET SOUND architecture is improved

Not only circuit designing but also the LSI manufacturing process was newly developed at AKM exclusively for AKM’s audio devices.  The AK4497 is the first device to utilize this process in AKMs foundry. 32-bit processing is integrated for the IRD (Impulse Response Designed) Filter, reproducing a detailed and natural signal wave. A low-dispersion short delay filter was newly added to the other five filters found in our previous generation device. So, six different digital filter types are selectable according to the user audio and system preferences.

● AKM’s Best Performance D/A Converter

Low-distortion technology achieves industry’s best performance of -116dB THD+N DAC with 128dB S/N characteristic. The AK4497 has the best performance among AKM’s D/A converters. In addition, OSRD (Over Sampling Ratio Doubler) technology greatly reduces out of band noise.

● Supporting High Resolution Data

The first in the industry, a 22.4MHz DSD input is supported. The digital input supports up to 768 kHz PCM and 22.4 MHz DSD (Direct Stream Digital), recreating high-resolution sound that is as close as possible to the original acoustic source.
