OK, but there's a noisy hum.

Preamps are noisy, but other than that, perfect!


Bad purchase

By Unhappycamper-gUhOz

I had been eyeing one of these in the local music store for a little while now, hoping that it could substitute for an audio interface for when I'm away from my home studio and only have my laptop. Where to begin, to start out when I opened the box it felt very delicate and cheap so I suspect it would not hold up very well to a lot of travel and being thrown around. There is a three position switch to select what kind of input you are making to it, either line, guitar or mic. The line input is much to quiet and really unusable, and the mic and guitar in settings are audible at least, but distortion becomes an issue at just about any volume setting that would be usefull. There is a lot of noise especially when the microphone preamp is in use... a constant -9.6db.I also experiance audio dropout after 40 seconds

I've been using this interface for over a year now. I've decided to get a USB mixer instead. It adds unwanted noise to your mix. I still don't what the "Advanced Driver" function does. I own a Triton and probably haven't heard the integrity of the sound engine because of it. About the mic preamps, most studio mics use XLR cables, the only audio inputs are 1/4 inch TRS so you'll end buying a separate preamp or mixer anyway. Cut out the middle man...Bottom line is, the UA20 is great for a beginning artist.


At last the noise problem revealed

By Anonymous

from Undisclosed

On changing to a new laptop, noise levels on recording increased to -30 - -40 db unaacceptable. Discovered that the problem is noise on the 5V supply into the unit. Any noise on the supply gets picked up when recording. This is most probably a design flaw.I have hacked a "solution" by putting a gigantic capacitor (condenser) on the USB supply to filter out noise and now it is around -60 db.Now you know what the story is... if you want clean recordings upgrade to a more professional unit.
