The following article addresses general connection and noise issues when using the UA-25EX with a computer:
-
Be sure to install the driver for your operating system. You may download the driver from the link below:
https://www.roland.com/us/products/ua-25ex/downloads/
Note: Be sure that you're using the UA-25EX with the black front panel (pictured above) and not the UA-25 with the silver front panel. If you're using the UA-25, you can download the drivers here: https://www.roland.com/us/products/ua-25ex/downloads/ -
Be sure that the ADVANCED switch on the side of the UA-25EX is set to ON. If this needs to be changed, close down all software, disconnect the UA-25EX from the computer, change the switch to ON and then reconnect the USB cable to the UA-25EX.
- Be sure that the sample rate setting of the UA-25EX is the same as that of your recording software's sample rate. Check the sample rate of the project you are working on within your recording software (e.g. Sonar, Pro Tools, Logic, etc). If this needs to be changed, close down all software, disconnect the USB cable from the UA-25EX, change the SAMPLE RATE switch setting and then reconnect the USB cable to the UA-25EX.
- Raise the buffer of the UA-25EX and possibly the audio software being used:
Adjusting Buffer - Try a different USB port on your computer. NOTE: Be sure to connect the UA-25EX directly to the computer. Do not connect to a USB hub while troubleshooting.
- Connect to a USB 2.0 port on your computer only--or a USB 3.0 port with backwards compatibility. Check the USB 3.0 specifications of your computer to determine if there is complete support for USB backwards compatibility.
-
Log onto your computer as a user with administrative privileges.
-
Close/turn off system monitoring/anti-virus software temporarily--this may be preventing your computer from recognizing the recorder.
- Try disconnecting the UA-25EX from the computer, download the latest driver, run the uninstall program that comes with the driver download, restarting the computer and then installing again:

b. At the left, click "Advanced system settings."

e. Select "Background services," and click [OK].
f. Click [OK] to close "System Properties." - Install the latest version of Windows or Mac.
- Scan for viruses or trojans with any antivirus software installed.
- Did you install a device, install software or a plug-in, or make a change in Device Manager just before the issue appeared? If so, it's possible that the change you made caused the connection or noise issue.
Undo the change or uninstall the driver or software (if you can), restart your PC, and then troubleshoot. Depending on the changes you made, some solutions might include:
- Remove or reconfigure the newly installed device.
- Roll back the driver to a version prior to your update.
- Use System Restore to undo recent changes. - Test the UA-25EX on a different computer to rule out a malfunction with the original computer being used.
- Test with a different sound--such as the soundcard installed in the computer. If the problem continues, the issue is not due to the UA-25EX. In this case, you'll want to contact the computer manufacturer.
- Contact the computer manufacturer and see if you can get an updated USB driver/controller installed--as a new version from the manufacturer may resolve USB issues with the computer you're using.
