Descriptions:
>Metal Aluminum Material
Made of metal aluminum and CNC high-precision processing, it has a comfortable grip and injects modern beauty into industrial design

>Proprietary USB interface
The proprietary USB audio solution driven by STM32F446 supports 24bit/768khz PCM data stream and DSD to DSD512 processed at this level

>AT Cut Constant Temperature Crystal Oscillator
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.

>Multiple Input / Output
LEO has Coaxial, Optical, AES / EBU, USB input and External clock input.
Dual AES / EBU output, I2S HDMI LVDS / I2S RJ45 lvcmos output Optical output, coaxial output

>FPGA DSP Processing Architecture
SPDIF coaial, 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.

>Proprietary USB interface
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

>Digital Isolation For High SNR
The digital signal is completely isolated by 50Mbps high-speed optical coupler Optical isolation can reduse noise substrate and achieve high signal to noise ratio.

>Large Capacitance
Large capacity capacitance can easily improve the dynamic ability, so that every note can be performed incisively and vividly

>O-Type Single Crystal Copper Transformer
The single crystal copper wire is wound layer by layer, which makes the power supply stable and strong, and meets the strict speaker load conditions. The self-made transformer can effectively reduce the noise base and low frequency.

>ARM STM 32F446
LEO is equipped with a proprietary USB audio solution driver by STM32F446, which supports 24bit/768khz PCM data stream and DSD to dsd512 processed at the level.

>Driverless On Mac & Linux
Mac and Linux connections can be used without installing drivers. Licensed thesycon USB driver for Windows platform.
