Genelec Monitors: Question regarding noise

Genelec Monitors: Question regarding noise

Youngling Posts: 9 Join Date: 3/9/13 Recent Posts
Hi,

I didnt find anything on google, youtube or the search funtion in this forum, so i hope somebody cna help me.

I recently tried some active monitors (in a similar price bracket as the 6010) and even though the sound was great there was a constant background noise coming from the active monitors, even when no signal was played, and it was simply too annoying for me as i could hear it clearly.

I googled some more and often read that active speakers simply would have noise.
The 6010A seem to be the recommended model for my room size (~16-20sqm).

How do the Genelec perform in regards of constant noise as soon as they are powered on?

I really appreciate some feedback. Thanks.

Have you checked it is not from the signal source? In my setup apple tv signal s/pdif produces much more noise in the background than the usb input from cpu.

You can test this by unplugging the Genelecs from the source and listen if theres any noise.

Hi Mattipuh,

Thanks for your reply.

I dont have the genelecs yet, I simply wanted to know if i have to expect constant background noise.

At least the 8030s doesnt't have any if DACs usb input is used.

This is as far as i can tell not related to the dac but to the amplifier thats present in all active monitors.

So to put it simply: Do the genelec monitors create audible noise when no signal is played?

Hi,

Self generated noise level for Genelec speakers is in the range of 5-10 dB (@ 1 meter distance, A weighted) which means that you need to be in a quiet room and put your ear pretty much next to the speaker in order to hear it. It is not audible from a distance. If there is audible noise coming out of Genelec speakers, it is generated by the device(s) connected to the speakers, not by the speakers themselves.

I actually checked further on the web and 10dB(A) from 1m seems to be quite audible.
5dB(A) would be probably much better for me.

are there specific models that are on the known to be on the low side of the noise level?

I was actually looking into the 6010A or 8020B but I do sit in only 1 - maybe 1.5m - distance and am now worried about the noise level.

Hi,

Can you point me to the source which states that 10 dB(A) is audible at 1 meter distance?

Thanks!

Hi,

sure: http://www.sengpielaudio.com/TabelleDerSchallpegel.htm

However it is German.

It compares 10 dB (not weighted A) with "rustling of leaves" - similar page in english:

However I would easily take your word for it if you tell i wont hear it :).

Hi,

Thank you! Unfortunately that kind of tables are very rough and should not be taken literally. It is very difficult to measure low SLP because it will require good equipment and also a very quiet environment. Typical background noise in a quiet room is around 30 dB! Anything lower than that requires a laboratory type environment.

I can assure that you can't hear any noise from 6010A or 8020B at 1-1.5 meter distance. :)

I try to convince the taiwan distributor to let me test a set of 8020 just to be sure :).
