AUDIOQUEST XLR Noise Stopper Caps Input

Nothing makes an AV system more irritable than RF interference. Even a system compromised of the best interconnects can be subject to it. It is the bane of dynamics and clarity. To reduce the amount of RF interference entering your system we recommend “capping” all unused RCA and XLR inputs and outputs. Why? Because a little cap to block the XLR port can greatly reduce unwanted noise and therefore the noise floor of the system. 

These caps can be placed in any XLR input ports. This means if you have any male XLR ports on your system not being used, simply plug these in and hear how much clearer your system gets.
