Features: [AK4499] AK4499 Premium Switched Resist or 4ch DAC 1. General Description The AK4499 is a 32-bit 4ch Switched Resisto r DAC which adopts newly developed tech nology, achieving the industry’s lead ing level low distortion and low noise characteristics. It corresponds to a 76 8kHz PCM input and an DSD512 input at m aximum, suitable for playback of high r esolution audio sources that are becomi ng widespread in Network Audio and USB- DACs Audio systems. In addition, it is capable of supporting a wide range of s ignals and achieving low out-of-band no ise. The AK4499 has six types of 32-bit digital filters, realizing simple and flexible sound reproduction in wide ran ge of applications. 2.

Premium Switched Resistor 4ch DAC
1. General Description
The AK4499 is a 32-bit 4ch Switched Resistor DAC which adopts newly developed technology,
achieving the industry’s leading level low distortion and low noise characteristics. It corresponds to a
768kHz PCM input and an DSD512 input at maximum, suitable for playback of high resolution audio
sources that are becoming widespread in Network Audio and USB-DACs Audio systems. In addition, it
is capable of supporting a wide range of signals and achieving low out-of-band noise. The AK4499 has
six types of 32-bit digital filters, realizing simple and flexible sound reproduction in wide range of
applications.
