The Introduction to AK4490EQ

The AK4490EQ is a new generation Premium 32-bit 2ch DAC that incorporates innovative technology to provide industry-leading low distortion and broad dynamic range. The AK4490EQ includes a newly invented switching capacitor filter called the "OSR Doubler," which allows it to support a wide spectrum of signals.

The AK4490EQ also has five types of 32-bit digital filters, allowing for simple and flexible sound tuning across a wide range of applications. The AK4490EQ supports PCM data up to 768 kHz and DSD data up to 11.2MHz, making it perfect for high-resolution audio source playback in network audio, USB-DACs, and car audio systems.
