Put Roland quality on your desk. With two digitally controlled mic preamps plus 2 channels of digital I/O and MIDI I/O, this interface is a serious value.

Capture great audio anywhere with the Roland UA-55 Quad-Capture USB audio interface. The ultra-compact, four-channel UA-55 Quad-Capture offers mobile musicians a ton of recording perks -- VS Preamps, 192 kHz/24-bit audio resolution, USB bus power, plenty of I/O, bundled DAW software, and more -- in a convenient, small-format interface that's as affordable as it is portable.

What's in the Box

No audio interface would be complete without the I/O essentials that the UA-55 Quad-Capture packs: two XLR/TRS combination inputs with premium mic preamps, two TRS outputs, coaxial I/O, headphone out, and MIDI I/O. It's just what you need to capture quality audio at home or on the go.

Recording's a Breeze with These Mic Pres

A pair of VS Preamps (digitally controlled mic preamps) deliver high-quality sound no matter what kind of recording is in the queue. Accompanying the preamps are two XLR/TRS combination inputs, independent phantom power, low-cut filter, phase invert, and digital compression for each channel. Take command of VS mic pres with the graphical Control Panel software (Mac/Windows) that ships with the UA-55 Quad-Capture.

Set Levels Fast With Roland's Auto-Sens Feature

The one-click Auto-Sens feature allows you to set your input levels faster than you can set the time on a microwave. Getting your levels just right is a matter of pushing the Auto-Sens button and playing your connected instruments.

"First Purchase from zZound, Roland UA-55"
Overall: 5 out of 5 stars

This review has been selected by our experts as particularly helpful.
Having done recording before on the PC, I was at least familiar with the concept of what I needed. However years had passed and I felt rather newborn once again looking for current solutions. I liked zZounds site setup and their great prices on "blemished gear. Plus quite the catchy name. So after review, site, article and blog seemingly endless research I decided on the UA-55. It fit what I would need it for and more. Well after all that reading and decision making I wanted my little device now. Second day shipping slipped fairly easily in. Though Ive always been a bit leary doings so because of other companies lack of follow through, no excuses needed to be made as the audio interface arrived right on time and in great shape. Unfortunately the excitement had to be put off as my PC had given up the ghost before package arrival. Well last night with new computer on hand I finally got to enjoy the whole process for the first time. The device is exactly what I needed for a smaller home recording setup. The included Sonar LE will take a little getting used to, but I still within 5 to 10 min was able to put down a test guitar track and try out a bunch of effect add ons. Go to Sonars site for a bunch more free add ons to the LE edition software. This was not only the perfect product, but also the perfect purchase. I look forward to reviewing the additional $1500 of products Ive ordered from zZounds since this transaction :-)

Sound is excellent. read more Effect add ons were varied and sounded quite good in the included Sonar LE. Ive just began to experiment so I know Im just barely getting the tio of the iceberg here of what can be tweeked with the sound. The only thing I noticed, and maybe there is a way around it, but so far it seems that if youre running with live effects, the delay time (latency) will be too much to effectively record while on. However this doesnt pose a problem since the UA-55 has enough i/o options to easily get around live pc sound effects.

The pre amps seem more than proficient at doing the job. I really like the auto adjusting input levels. Just plug in your instrument/ mic push a button, play for a few seconds and... perfect levels. Also the i/o options give you many different ways to set up your studio.

Ease of Use
Like I said before, 5 - 10 min and I was recording. I read just enough to make sure I wasnt going to damage anything and I was off. Make sure you do read about the input settings as there are choices on what type of instrument or mic will be used and if it requires additional power. Sonar looks quite a bit more advanced than Audacity which I had used before, but if you dont want to use it, the device will work with other DAWs as well.

Seems sturdy and well constructed. The thing I dont often hear in reviews on products like these is how well the item works in real world situations. Such as its ability to stay on a desk with cords and such plugged in and recording. The UA-55 passes with flying colors. Inputs are snug and wont pull out everytime you move either. Great all around device.

I did a lot of research and as far as audio input devices go, this is a perfect match of price vs performance if this is the amount of inputs you will need. Full bands would want to step up to a device that probably did have more but even then I would still recommend Roland.

Manufacturer Support
No issues yet. But because of everything else, still giving perfect for benefit of the doubt.

The Wow Factor
I came from using an old Soundblaster with the front panel interface, so this is science fiction in compairison :-)
