Two XLR/TRS combo inputs are provided for the preamps, plus independent phantom power for each channel.

LOW-NOISE POWER SUPPLY

Record vocals, guitar, keyboard, or other instruments with superb quality through the DUO-CAPTURE EX into the iPad using your favorite iOS apps. Additionally, the DUO-CAPTURE EX can function as a USB-MIDI interface to control iOS apps with electronic instruments such as MIDI keyboards, V-Drums, etc.

Hi all,
I am using the Roland UA 22 Duo Capture with PC and Ipad. It can be charged with the same adapter that comes with the GR 55 while using with Ipad. Works great.

Got one too and I could not be happier.

Thanks for the info about using my GR-55 adapter with it !

Roland Duo-Capture Ex UA-22. Simple AB mic preamp tests.
Postby BGR » Sat Feb 28, 2015 3:09 am

Received a Roland Duo-Capture Ex UA-22 today. And I wanted to share my first AB tests of the preamps.
Three stereo track files in FLAC format.
No editing, effects or fades.
Exported from Auria to AudioShare. Opened in WiFi Disk. Transferred to a Mac OS X 10.8.5 system. Converted to FLAC with XLD. And uploaded to DropBox.

Feel free to download.

A few characteristics so you can skip the audio descriptions:
-The Roland Duo-Capture Ex UA-22 is battery powered with 3 rechargeable AA batteries.
-There is no powered USB hub between the UA-22 and the iPad 4. When the UA-22 is in TAB mode, you must use either batteries or a power supply. Also, when in TAB mode, the USB output from the UA-22 can be connected directly to the Camera Connection Kit Lightning to USB cable from the iPad 4. And also, when in TAB mode, the UA-22 is supposed to run only in 44.1kHz mode. An internet blogger and reviewer that specializes in video has said that it can also run in 48kHz mode; but I have not tested that yet.
-The gain knobs from the UA-22 have 12 markings above the minimum or 0%. Being the marking number 12 the maximum level or 100% of gain.
-And last but not least, the room is not treated. It is a normal small living room surrounded with furniture. Kind of quiet. But still not a perfect sound proof environment.

CAUTION: Use some nice headphones to listen. Just be aware that the audio files start out quite quiet and get louder towards the end.

-To test the noise floors of the interface and a pair of inexpensive large diaphragm condenser microphones. Split into mono tracks in your favourite DAW so you can hear and see the differences.
-Stereo track.
-Left side of track: AKG C3000. Large diaphragm condenser cardioid microphone. Switches set to flat frequency response and no padding.
-Right side of track: t.bone SC-1100. Multi-pattern large diaphragm condenser microphone. Switches set to cardioid mode; and to flat frequency response.
-Phantom powered.
-Placed between 25 and 30 cm away from the microphones.
-Microphones are set side by side as close as possible.
-Before minute 2:30 there is an audio description of the test. The actual test begins after the minute 2:30.

-Phantom powered.
-Placed between 25 and 30 cm away from the microphones.

-To test the noise floors of the interface and a pair of inexpensive dynamic microphones. Split into mono tracks in your favourite DAW so you can hear and see the differences.
-Stereo track.
-Left side of track: AKG Live Perception P5. Dynamic microphone.
-Right side of track: Samson Q2U. Hybrid dynamic and USB microphone. In XLR mode.
-Placed roughly 10 cm away from the microphones.
-Before minute 1:23 there is an audio description of the test. The actual test begins after the minute 1:23.

EDIT:
The Roland Duo-Capture Ex UA-22 provides true 24bit samples. I verified the files with Goldwave following the steps that user fgplayerx proposed.

EDIT:
Some features I found out about while testing the Roland Duo-Capture Ex UA-22:
-In TAB mode, because you have to power it with three AA batteries or the optional power supply, you can connect it to a computer or a laptop without drawing power from the USB port. Using it like this, you have no other option but to record in 24bit,44.1kHz. But for those who use a laptop to record, this feature can help you prolong the laptops battery life.
-In TAB mode, you can use it as a standalone preamp, mixer or monitor. The monitor switch on the back gives you the option to monitor in mono, stereo or no monitoring at all. Just connect what ever you need to amplify and start using it without a computer or iOS device.
-And, also in TAB mode and using Harmonic Dog Multitrack DAW Ipad App , you can choose all the combinations of bit depths and sample rates available in Multitrack DAW. 16 or 24bit. 44.1, 48, 88.2 or 96kHz. Providing true 16 or 24bit samples. Below is a dropbox link with a zip file the original audio files I recorded for this test. And I already verified the bit depths with the Goldwave method that user fgplayerx proposes.
