Likewise, D/A conversion is similarly clean and noise-free, with tons of gain.

some hissing horrible noises at times when it gets

I couldn't record anything , I use a dynamic K&K Mic , the hiss only goes away when I connect it to the line 2 input in the back , which disconnects the XLR input , but the volume was very low , and when I amplify it by audio software I get loud noise as usual

Solidly built, I don't experience any weird noises when I'm using it, even when I have a project that has high CPU usage

I was amazed the unit produced the same noisy white noise in between words

At an input level high enough for a reasonable volume range, the noise is fairly prominent

It produced a white noise and whine so loud it was completely unusable

I bought this because I found that while doing mixing (of recordings) that sometimes, in the quietest passages, the sound card in my laptop would create some spurious noise - so my intent here was to use it as a sound card (external) to improve the signal to noise ratio

No audible noise in the output; quiet as a church mouse

If I had money to burn I'd definitely go for something higher-end, but on my budget this box now works fine

, I'll probably get another, even though they're out of stock, seeing as I damaged mine.
