Excellent Resolution - Support up to PCM32bit768kHz and DSD512 Native.U90 has excellent transparency and resolution.A whole world of transparency opened for you. Just like musicians crowded together on a smaller stage, the U90 opened up the stage and spread apart the players on that stage creating a sense of greater transparency, providing enough room to hear the instrument's ambiance.
Multiple interfaces output - U90 has 1x IIS, 2x AES, 2x coaxial, and 2x optical output.It is suitable for both domestic and industrial applications.It can be matched with different device to adapt to different standards
IIS high compatibility - In order to be compatible with different brands of different IIS transmission definitions, U90 is equipped with 4 sets of switches to set the IIS pin definitions, which can be compati- ble with most other brands of IIS definitions through reason- able settings.It is worth mentioning that the U90 defines a mute pin in IIS transmission. When used with other TOPPING DACs, it can greatly reduce the pop noise when switching the samplingrate.
UItra low jitter - U90 uses a femtosecond crystal oscillator and CPLD to process the clock and optimize the digital signal, achieving incredible jitter suppression
Built-in USB isolation-The built-in USB isolation can effectively eliminate the noise introduced by the ground loop which can cause damage and inaccurate measurements. The isolation protects equipment from electrical surges and transient voltage spikes.Additionally, isolation minimizes conducted noise from static discharge, magnetic fields, and radio frequency interference

وصف

The U90 is a high performance USB audio bridge with coaxial,optical,AES and IIS outputs.Rich output ports make U90 has strong usability.
And it uses high-speed isolation technology,which can get rid of the ground loop noise from the PC.
We believe that high-quality U90 could bring you more fun at enjoying HIFI music.
