Hypex Ncore NC502MP - audible hum on one channel?

[yllanos]

I have Audiophonics LPA-S500NC (https://www.audiophonics.fr/en/powe...tereo-class-d-ncore-2x500w-4-ohm-p-15016.html), in my bi-amped setup, and can’t hear any hum in any of the channels … my speakers are Neat Motive 1 ... I believe their sensitivity is about 87 dBm … all connections are XLR

I own the exact same amp. No hiss or noise on my Magnepan MMG

I just purchased two of these (Audiophonics LPA-S500NC). No hiss, only when you put your ears right next to the speakers. The amp itself has a high pitched noise which to me only is audible when you put your ears right next to them.

So no need to worry
