Troubleshooting
Our USB device has been subjected to rigorous tests before shipping. Most of the incompatibilities
we have experienced are not from the USB capture device itself, but from the sophisticated software
and hardware combinations of PCs or laptops. Please try the following suggestions
1. OBS is a popular USB capture freeware and has excellent compatibility with most devices. Please
download it and start with OBS if users are not familiar with USB capture devices.
https://obsproject.com/download
2. Due to the complexities of OS and computer hardware, different USB ports on PCs or laptops may
have different performance or limitations. Please try all USB ports to see if there are any differences.
3. Please use the included USB cable. We do not guarantee the overall performance when the USB
capture box is connected with other USB cables.
4. SDI cable quality may also play an essential role when capturing. Please be sure the SDI cable is
capable of 1080P@60 SDI signal transmission or better. Try different cables when the device is not
able to work as expected.
5. If audio has noise, please adjust sampling frequency setting on PC or laptop. If the default
sampling rate is 48000 Hz, please select 44100 Hz and vice versa. The path of setting sampling
frequency on windows 10 is:
Start → Setting → System → Sound → Device properties → Additional device properties → Advanced
