COMPATIBILITY
U90 is compatible with all the DACs (Digital to Analogue converters) as it offers a USB input and multiple outputs (2x AES, 2x OPT, 2x COAX, 1x IIS-LVDS). If you have multiple DAC & Amp setups this device will serve your purpose if you alternate between numerous DACs.
USAGE
If you alternate between numerous DACs, Topping U90 is a fantastic companion for you because it eliminates the difficulty of switching between different outputs and connections!
WHAT IT DELIVERS
A USB bridge, which is effectively a DDC, sits atop U90 (Digital to Digital Converter). So, what exactly is a DDC, you ask? A DDC converts the digital signal coming from the streamer or music source into various digital signals like IIS, AES, Coaxial, and Optical. With a higher-quality clock design, you can be sure that the sound is sent from the source to the DAC with ultra-low jitter, accurate timing, and no distortion. Compared to direct USB connection to DAC, you can tell that with a DDC, the timing of the instruments is corrected, and improves the clarity and cleans up the background.
PROFESSIONAL GRADE USB AUDIO BRIDGE FOR HIGH-QUALITY AUDIO TRANSMISSION
Topping presents the all-new U90, a high-fidelity USB Bridge for your desktop audio chain. The Topping U90 processes high-resolution audio signals via USB and provides you with digital output via I2S, AES, Coaxial, and Optical output ports. It has a self-designed Ultra-Low Jitter Clock consisting of a high-quality CPLD processor and femtosecond crystal oscillator that ensures you get a clean sound transmission. Topping U90 has an in-built USB isolator that effectively reduces the noise caused by the ground loop while supporting high-resolution audio streams and embedding an optimised audio architecture to maintain the integrity of the original signal.

COMPLETELY ADJUSTABLE I2S OUTPUT WITH BUILT-IN 12V TRIGGER FOR EASY OPERATION
The Topping U90 features a specially designed I2S output with four different sets of switches to set I2S output parameters. With four sets of I2S controller switches, you can choose pin definitions for the I2S phase, MCLK, DSD flag, and IIS DSDR, which can be compatible with most other brands of IIS definitions through easy configuration. The Topping U90 comes equipped with a 12V trigger on the back panel. This simple jack lets you create a network between any units that also feature a 12V trigger. When connected, it makes one product control the power of the other products in the system. When you turn on one unit, the rest of the system comes on automatically.



FEATURING MULTIPLE OUTPUT PORTS TO CONNECT WITH VARIOUS DEVICES OF YOUR CHOICE
Topping U90 offers an array of output ports to connect to audio devices. Topping U90 has seven outputs - 1x I2S, 2x AES, 2x OPT, 2x COAX, compatible with domestic HiFi setup and industrial devices applications. You can connect Topping U90 to multiple sets of DAC/AMPs. In other words, you can feed audio signals from a single USB input to different pairs of desktop chains with the help of multiple output ports on the device. U90 supports up to 32bit/768kHz via IIS-LVDS and up to 24-bit/192kHz for AES, optical, and coaxial.



EQUIPPED WITH USB ISOLATION AND A SPECIALLY DESIGNED ULTRA-LOW JITTER CLOCK
The Topping U90 is engineered with a built-in USB audio isolator. This isolator is embedded to electrically isolate itself and the rest of your system from your source. It eliminates ground loop noise by as much as 50dB in real-world scenarios ensuring you don't need to add another USB isolator in the audio chain. Topping U90 also utilises a pair of Accusilicon femtosecond oscillators for its clock signal combined with an Altera MAX II CPLD. This circuit allows perfect synchronisation and management of the clock signals for extremely efficient jitter suppression while optimising the digital signal with great precision.
