There is no ASIO support, moreover, there are no drivers on the site, the manufacturer used a generic chipset, the drivers for which the OS installs itself. On the manufacturer's website in the drivers section there is only a link to ASIO4ALL, which fastens support for devices without it.
As a result, I/O latency with a minimum buffer without clicks on i5 (650 samples) is 3.5 times greater than on any other cards, which makes it impossible to use it with real-time effects.
A disgusting preamp, at least for the instrumental input, did not even check the microphone one. Strong background noise, but the worst thing is that by adjusting the input gain to the point of clipping, the DAW signal turns out to be something like minus 10 dB! If you allow the red diode to be lit at the input, then, of course, clipping is clearly audible, but in the program the level still does not significantly reach zero. It turns out that she has an attenuator between the preamp and the DAC. The result is a guitar sound with a lot of noise, little gain, and a lot of delay.
The headphone volume control in the minimum volume region first turns on the right channel, and only when the volume is increased does the left one appear and further away they are compared.
