During rack mounting, ground connections are created between the devices via the metal rails. This is the most common cause of humming noises! Our Hummfrees interrupt these ground loops, the devices are electrically isolated from each other and attached to the rails. An additional effect: the front panels of the devices are protected from mounting damage.
Quick and easy to install: Pull the device 5 cm out of the rack, fold the Humfrees sideways around the corners of the front panel and fasten the device back into the rack with the screws. Now just make sure that the devices do not touch each other directly on the surfaces. Existing cable connections in the rack do not need to be disconnected.
For M5 screws you can use our enclosed adapter sleeves.
