This DAC module is built around the chip DAC AK4490EQ capable of supporting a decoding HD 32bit 384kHz.
AKM AK4490EQ chip may receive audio streams through a coaxial or USB input. The selection of the source is done simply through a jumper. The coaxial input PCM supports up to 192kHz. The USB input for use with an interface will support the DSD 11.29964MHz, PCM 384kHz and 352KHz DXD. This DAC board is thus a very practical solution to integrate support high-quality audio files to your building projects.
This chip works with technology Velvet Sound in architecture in both channels. This technology can enhance the details of the sound while maintaining a very low distortion. To further increase the accuracy, two 32-bit filters are integrated into the architecture.
The card works with operational amplifiers LME49710NA. They are designed for high fidelity audio use and contribute to excellent sound quality.
The dedicated power supply of the DAC1 is provided. It has an AC input 15Vx2 & 9V to power all the functions of the card.
This power is supplied on a separate card that will facilitate the installation issues.
A - AC Input 9V
B - AC input 15V x2
C - Slot for USB chip
D - Selector USB / COAX
E - Output Coaxial
F - Analog Output
