Overview
[AK4462] AK4462 117dB 768kHz 32-bit 2ch Premium DAC 1.
General Description The AK4462 is a new generation 32-bit 2ch Premium DAC which adopts VELVET SOUNDTM technology.
It corresponds to a 768 kHz PCM input and an DSD512 input at maximum, suitable for playback of high resolution audio sources that are becoming widespread in network audios, USB-DACs and Car Audio Systems.
In addition, “OSR-Doubler” technology is adopted, making the AK4462 capable of supporting wide range signals and achieving low out-of-band noise while realizing low power consumption.
Moreover, the AK4462 has six types of 32-bit digital filters, realizing simple and flexible sound making in wide range of applications.
Applications: AV Receivers, CD/SACD Players, Network Audio, Digital Audio Players, USB DACs, USB Headphones, Sound Plate/Bars, Car Audio, Automotive External Amplifiers, Measuring Instruments and Control Systems.
