Soft Control Decoding Board Balanced Output 32Bit PCM786KHz

Detailed Information About The Product:

The new version of the AK4493SEQ chip has a 32-bit 768Khz sampling rate and DSD512 hard decoding capability. The supported sampling specifications are faster than PCM1794A. It has high resolution, speed and transparency, and three-band balance, especially the analog flavor is stronger, and the vocals are mellow and sweet. , very cost-effective.
BD93 uses a total of two AK4493SEQ chips. One AK4493SEQ chip is only responsible for one channel. The independent circuit is truly balanced. The two channels do not interfere with each other. The sound is crisp, delicate, clean and transparent.
Adding dedicated MCU soft control, deep optimization, fully opening the function of AK4493SEQ, the sound quality is improved to a higher level. It also provides 6 sets of digital filter parameter settings on the carrier board, opening DSD NOS mode, volume control and other functions.
The IIS input of the BD93 board is designed to be compatible with the Amanero USB interface. Use the matching cable to seamlessly connect with the appropriate USB module. It can also be used with the online version of the B18 digital board, connected in a joint control mode, and equipped with a suitable power supply. The shell can be assembled into a complete decoder with infrared remote control function.
It is recommended to use linear power supply for power supply. Details, speed and fineness are improved, and the sound field is wide and accurate.

enter:Standard 4-wire IIS interface/20P pin header interface is compatible with Amanero USB interface. Supports sampling specifications: PCM 44.1K~384K 32BIT
DSD DSD64, DSD128, DSD256
(The AK4493SEQ chip itself supports hard decoding of DSD512, but in actual use, it automatically switches between PCM/DSD. If the board does not have additional auxiliary signals, it can support DSD256 or lower and get better switching effects easily)
