The following article addresses general noise issues when using the STUDIO-CAPTURE with a computer:
- Be sure that only a Roland brand PSB-120 or PSB-1U model number power supply is being used. 3rd party power supplies can cause the product to not operate properly.
- Follow the troubleshooting info in the following article--as noise issues are often a result of grounding problems:
Resolving Grounding Problems - Reset the internal settings of the STUDIO-CAPTURE:
STUDIO-CAPTURE: How to Reset Internal Settings -
For troubleshooting purposes, disconnect all USB devices except the mouse and the STUDIO-CAPTURE—this includes disconnecting the computer keyboard, printer (if applicable), USB hub and/or USB breakout box, etc). If the noise disappears, troubleshoot the device introducing the noise.
-
Physically disconnect any cables connected to any inputs or outputs of the STUDIO-CAPTURE and troubleshoot with headphones--this means that a USB cable, power supply and headphones are the only cables physically connected to the STUDIO-CAPTURE.
NOTE: Be sure that speakers are not connected to the STUDIO-CAPTURE and the speakers are not plugged into any power outlets for this troubleshooting.
If the problem disappears, the noise is being introduced from one of the audio cables or the speakers themselves. Start reconnecting cables, one by one, until the noise is reintroduced. -
Be sure that you are using balanced cables connected from the STUDIO-CAPTURE's outputs into your speakers. If the noise still continues, try using ground lifts on your speakers (if you have these available) as you may have a grounding issue.
If the problem continues, leave all cables physically disconnected from the STUDIO-CAPTURE, except for the USB, power and headphones, and continue the troubleshooting: -
Try connecting the STUDIO-CAPTURE directly to each USB port on your computer (do not use a USB hub or USB breakout box for this test)—to rule out one or more USB ports causing the problem.
-
Move the STUDIO-CAPTURE away from your computer video monitor—as the video monitor may be introducing this noise.
- Move the STUDIO-CAPTURE away from the computer itself--as the computer's power supply could be introducing this noise.
-
Disconnect the STUDIO-CAPTURE and test with the computer’s internal soundcard. If the noise problem continues, the STUDIO-CAPTURE is not the cause of the problem.
-
Connect the computer’s power, and the computer video monitor’s power to a different power circuit. The noise may be a result of dirty power or another issue from the original power circuit. Be sure that your computer's power, your computer's video monitor's power, the STUDIO-CAPTURE's power and your speakers power are all connected to the same outlet--i.e. on the same circuit.
-
Test on a different computer (if available) to determine if there is an issue with the STUDIO-CAPTURE that continues on a different computer system--or if the computer is the source of the noise issue.
