NEW AK4493EQ
123dB 768kHz/32-bit 2ch Premium High-end D/A Converter

As an upgrade from the best-selling AK4490EQ, which has been adopted by many high-end audio products since the launched in 2014, AKM, has developed the AK4493EQ, a premium high-end D/A converter.  The AK4493EQ uses an improved VELVET SOUND architecture, optimizing the circuit design.  It also employs AKM’s original dedicated audio process.  This process has improved electric margin, low frequency noise performance, and the original acoustic sound expression that can be found in the sound strength and the data amount.
Low-distortion technology achieves -113dB THD+N DAC with a 123dB (stereo) SNR characteristic.  The AK4493EQ has higher performance than the AK4490EQ.  The digital input supports up to 768 kHz PCM and 22.4 MHz DSD, (Direct Stream Digital), as an industry first.  32-bit six different digital filter types are selectable according to the user’s audio and system preferences.
The AK4493EQ is ideal for Network Audio players focusing sound quality, SACD players, and Hi-Res audio systems supporting high-resolution sound sources.

  • - Maximum Sampling Frequency, Bit rate: PCM 768kHz/32-bit, DSD 22.4MHz
  • - SNR: 123dB
  • - THD+N: -113dB
  • - Sound Color Digital Filter: 6 types
