Please contact Hegel and explain your hum issue to their technical support staff.
i also suggest you ask your retailer where you purchases your amp. The hum issue needs to be addressed.
Hegel hum?
Spent a week or two enjoying my new H400 and noticed a faint hum between the time I turn it on and before I play music. Also there when I pause after playing a while. Note that the hum is only apparent when I bring my ear a foot away from the amp. I’m quite pleased otherwise but am wondering if this is normal?
