8351's hissing harder then normal at Idle

Dear Illka,

Yesterday I installed my 8351 in my new studio. When I powered them up and performed the glm calibration I noticed that one of my 8351's has a much louder idle hiss than the other. I never noticed this before. Maybe it is the room which is different but I dont think so. With my ears 60 cm from the 8351's the difference is very noticable. Eqsily twice as loud. I already tried to restore factory settings this dindt work. It really iddle noise since I hear it when only the power cables are plugged in.

I threat the monitors extemly well. No single scratch, always very carefull and transported in their original
Packaging. They are one year old approx.

I'm afraid something is wrong with the hardware.
Do you have any solution maybe before I send the loud hissing one over to Finland

Is there another hard reset method?
Pretty sad about it.

60 cm listening distance sounds really small, are you truly listening that close? :shock:

Hi Illka,

Thank you for your fast reaction. My listening position is in a 1.2m triangle. So from my sweetspot the monitors are 1.20 from each ear. In this position at 1.2m I can clearly hear the right monitor putting out a louder hiss/white-noise.

Just to be sure I will swap the monitors from L->R to eliminate this is the room I'm hearing. This was the reason I mentioned the 60cm test. This eliminates more of the rooms behaviour I suppose.

To bad. I swapped the monitors. Still very remarkable which monitor hisses most. A least about twice as much. :( :)
I will fill out the forms. Original boxes are here for Shipment. Can I update the firmware maybe? Is that possible?

For sure it is not a firmware issue so an update does not help. Please fill out the service request form so that we can start to process this with your local distributor. Where did you purchase the monitors from and where are you located?
