Musician Leo Digital Interface

Leo adopts AT cut constant temperature crystal oscillator design. AT cut constant temperature crystal oscillator is the crystal oscillator with the highest frequency stability and accuracy at present. The internal temperature control circuit controls the temperature to achieve the highest frequency stability. SPDIF coaxial, optical, AES/EBU input supports digital audio format up to 24bit/192khz. Digital data is decoded by on-board FPGA, the signal path is shortened and bad signal coloring is eliminated. Leo is equipped with a proprietary USB audio solution driven by STM32F446, which supports 24bit/768khz PCM data stream and DSD to dsd512 processed at this level. The digital signal is completely isolated by 50Mbps high-speed optical coupler Optical isolation can reduce noise substrate and achieve high signal to noise ratio.
