Swissonic UA-2x2

if you want to record and listen at he same time then you cant, there is no direct monitor on the interface, so your input comes back while you a recording a fraction of a second after you produce it ,the mono toggle only affects headphone output , its about time every usb interface should be able to output mono on both channels if required, so your guitars or microphones can be on both left and right channels at the same time this has to be done on software at the moment . this item was returned.

after using it for half a year, one channel starts making loud white noise, and headphone amp aslo mstarts make a noise too, if i were you i will buy more expensive with better quality that will last longer

Have to unplug the interface every time I turn on my computer or change sample rate before I can use it. Also, the interface just stops playing at random.
