Rolls HE18 2-channel Hum and Buzz Remover
(Hand built in the USA)

If you’ve got hum or buzz in your audio signal, the HE18 is the solution you need. Almost all AC hum is caused by ground loops. These ground loops act like radio antennae, picking up hum and noise. The HE18 removes many causes of noise by eliminating the ground potential.
