Multiple interfaces output
U90 has 1x lIS, 2x AES, 2x coaxial, and 2x optical output.
It is suitable for both domestic and industrial applications.lIS 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 lIS pin definitions, which can be compatible with most other brands of IIS definitions through reasonable 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 sampling rate.Ultra-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 l JSB isolation
The built-in USB isolation can effectively eliminate the noise introduced by the ground loop.12V Trigger
U90 also provides a 12V Trigger interface. When used with other devices with 12V Trigger interface, U90 can be used to control other devices to turn on and off. It greatly facilitates the use.
