Intermittent hum heard through speakers or headphones when using a USB2.0 interface

An intermittent low frequency hum may be heard through headphones or speakers when the output device is being housed in a ZB1 caddie using a USB2.0 interface. The frequency is variable, and the hum may be constantly present or come and go over time. This has been reported with the RX6 but might occur when using other RP/RX devices with the USB2.0 interface. This problem is only found with USB interfaces and disappears when using the gigabit interface.


Upgrade to the Gigabit interface.
