The following article addresses general connection and noise issues when using the QUAD-CAPTURE with a computer:
-
Be sure to log on as a user with administrative privileges on your computer.
-
Close/turn off system monitoring/anti-virus software when installing the driver--such as the Norton software you have installed. If system monitoring software such as anti-virus programs are installed on your computer, close them while troubleshooting.
-
Connect directly to your computer via USB. Do not connect to a USB hub while troubleshooting.
-
Be sure that you are connecting to a USB 2.0 port on your computer; 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.
- Test with a different USB cable. Be sure to keep the USB cable length under 10 feet.
- Test on different USB ports on the computer.
- If using a USB adapter, such as USB A female --> USB C male, be sure that the adapter is compatible with the computer. It may be necessary to test with a different brand adapter (if available).
- Be sure that the USB port that the QUAD-CAPTURE is connected to is supplying at least 480 mA of power or higher. Check the specifications of the computer for this information.
- Note that connection issues can occur with an audio interface if a computer falls asleep while connected. If the QUAD-CAPTURE does not work correctly after resuming from Sleep mode, you should exit all applications/software, and then disconnect the USB cable of the QUAD-CAPTURE and reconnect it.
Be sure to not play or record audio for a minute or so after the computer restarts--to allow the system to fully "wake up" and communicate with the QUAD-CAPTURE completely.
To avoid this occurring, it's recommended to not put the computer in sleep mode. - Raise the buffer setting of both the QUAD-CAPTURE as well as the audio software (DAW) being used:

Try disconnecting the QUAD-CAPTURE from the computer, running the uninstall program that came with the driver download, restarting the computer and then installing:
QUAD-CAPTURE Downloads -
Install the latest version of Windows or Mac. Contact Microsoft or Apple for proper update procedures.
-
Did you install a device, install software or a plug-in, or make a change 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. - Scan for viruses or trojans with any antivirus and/or antimalware software installed.
-
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.
