● Dynamic Sound Playback with Large Amounts of Playback Information:
VELVET SOUND architecture is improved
Not only in the circuit design, but also the LSI manufacturing process was developed at
AKM exclusively for AKM’s audio devices. The AK4493EQ adopts this process,
improving low frequency noise performance and electric margin. 32-bit processing is
integrated for the IRD, (Impulse Response Designed), filter, reproducing a detailed and
natural signal wave. A harmonic sound filter was newly added to the existing five filters
found in our previous generation device. So, six different digital filter types are
selectable according to the user’s audio and system preferences.
● Even Higher Performance than the AKM’s Best Selling DAC, the AK4490
Low-distortion technology achieves -113dB THD+N DAC with a 123dB* S/N
characteristic. The AK4493EQ has higher performance than the AK4490. In addition,
OSRD, (Over Sampling Ratio Doubler), technology greatly reduces out of band noise. *
126dB in normal mode.
● Supporting High Resolution Data
An industry first, a 22.4MHz DSD input is now 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.
