Features: Supports up to 32-bit /384kHz sampling rates, accurately reproducing sound detail, providing rich timbres and dynamic ranges, making the auditory experience more realistic and touching. Built-in low-pass filter: The module is equipped with adaptive low-pass filter, which can effectively suppress high-frequency noise, make sure the purity of the output, and optimize sound quality. Analog sound output: It provides a standard output, which can be directly connection, allowing users to conveniently enjoy sound quality. Use of components: Capacitors and resistors are adopted to the stability and durability of the module, ensuring that its remain unchanged over long-term use. Suitable for sound enthusiasts to build by themselves, providing sound output and meeting the demands of high-end sound.
