Long time lurker, first time post.
Is it normal to hear an audible hum (only from the right speaker) from the Hypex Ncore NC502MP modules?
I recently purchased a Audiophonics LPA-S500NC, a French made stereo amplifier that utilizes the Hypex Ncore NC502MP module.
My set up is as follows: new MiniDSP SHD --> Audiophonics LPA-S500NC amplifier (via XLR cables) -->pair of new Kef R3 (via Amazon basic 16gauge speaker wire/monoprice banana plugs).
I set everything up and I immediately noticed an audible hum coming only from the right speaker - it sounds like a ground loop. The left speaker has no hum noise. The noise through right speaker is noticeable at 6 inches but barely there at a foot away. Noise disappears from right speaker when I unplug the XLR cable from the amplifier (i tried various xlr cables and different outputs on the SHD but the noise was still there in right speaker only).
The amplifier was returned to Audiophonics. They tested my amplifier and also noticed a low hum in right speaker but said they could only hear it if their ears were right next to the speaker. They also state that this hum is present in ALL of their LPA-S500NC currently in stock. According to Audiophonics this is NOT a defect in the product because 1) i should expect noise in a 500 watt amplifier; 2) the hum is only apparent when they put their ear right next to the speaker.
Perhaps the noise floor is lower in my home compared to their office but how is this not a defect in their amplifiers when there is noise coming from only the right channel on ALL of their amplifiers but not the left??
Is this hum noise on the right channel limited to just Audiophoincs amplifiers or is it present on all Hypex Ncore NC502MP modules? (e.g. March Audio, Apollon audio, etc)
Am i crazy to expect no hum noise on these newish Hypex Ncore amplifiers? I feel like I am being gaslit lol.
Any input would be greatly appreciated!! Thanks.
