Therefore, you would need to connect your unbalanced source to the input, then use an XLR cable to connect the output to the XLR input of your Focusrite audio interface.įor more information about DI boxes, see this article. Typically, DI boxes have a ¼ inch jack input and an XLR output. For longer cable runs, a DI box that includes a transformer can reduce the chance of noise entering the recording further. There are lots of DI boxes on the market, but we recommend trying one with a ground lift switch. A DI box converts an unbalanced signal into a balanced signal. If you're getting unwanted hum or noise when recording unbalanced sources (for example, guitars) you can use a DI box to try to reduce the hum. *For further information please see this article: Y ou can get ground loop isolators such as the ART Cleanbox that work to prevent audible ground hum/noise. If the ground hum can be heard in your headphones connected to the interface and i n your monitors when you use balanced cables, a nd you are unable to find the source of the ground loop in your setup : The connection will only be balanced if the monitor speakers you're using also have balanced inputs, so it's a good idea to check the manual for the monitors. Īll ¼” jack line outputs on Focusrite interfaces are balanced, which means you can use a balanced (TRS) jack to jack cable or a balanced (TRS) jack to XLR cable to connect your monitors to your interface. Often, using balanced cables * can reduce the likelihood of hearing ground hum/noise through your monitor speakers. If you're using a laptop, you may find that the hum/noise stops when the laptop’s power cable is disconnected, which would rule out the components in the laptop causing the issue and would suggest it's being caused by the power supply or electric wiring in your building instead. Make sure you are using a power supply that has been approved or made by the manufacturer of your computer. If the problem doesn't occur with another computer, it may be the case that the wiring in the computer's power supply is not suitable or the components in the computer are generating unwanted noise. If you find the issue does not occur in a different building, poor electric wiring and/or other electronic devices in the same building could be the source of the problem. This will not solve the problem, but it can help narrow down the ground hum source. Always try a different location or computer to see if this makes a difference. It could be an issue with the computer or the building you're in. There are also useful links at the bottom of the article with more information. Ground hum/noise happens for a number of reasons the list below shows the potential causes of ground hum with audio interfaces and how you can solve them. Glitches in audio that occur with mouse movement or hard-disk activity.Both of these issues can often cause unwanted audible effects that include:
