Monitor Noise?

I just bought a pair of the KRK V6's and I have no experience with mixing (first studio speakers I have ever heard) so I wasnt sure what I was looking for, and I couldn't get very conclusive examples of what to buy from the search button cause everyone thinks that something else is better. So I went and listened and I picked these based on price/sound.

Are these good speakers? I got them for 640$ (XLR-TRS cables too)

anyways, I have 2 issues with these speakers, the first is that when I put my ear really close (2"-4") I can hear electronic noise/interference/whatever its just that hummy/statiky/noise-that-sounds-kinda-like-a-guitar-amp/ noise. Its not very loud when I am sitting at normal distance, but it was loud enough for me to notice it in a quiet room. Are studio monitors supposed to be dead quiet?
the noise continues to happen even when I unplug the cable from the back of the monitors. so its an internal monitor issue.

the second problem is, whenever I turn my computer off, the speakers pop really loud, like a quick poppopbang. This happened on my old speakers but it wasnt as loud. I think It has to do with the fact that its plugged into my Delta44? and something happens when the power goes off to the PC?

is it ok for the speakers to experience this pop? (its happened twice so far, when i forget to turn them off before I turn off my computer)

this is getting sort of long, but if anyone can answer my questions, I would be greatly appreciative!
 
From what I hear these are quite good speakers as for the Noise you get when shutting down your PC i get that also with my Delta 44 and my yourkville Monitors so I simply just turn off my Monitors before my PC and as for if the Poping noise will hurt your speakers ,Probably not unless you have them turned up really loud but you should be OK....

As for the Backround Humm i also get a small Backround humm, i don"t know if it is a 60hz AC hum or and Ground hum or some sort of RF or EMI Interferance because they are in a Room with a CRT Monitor ,PC and Florescent lights which all put off Interferance that will leak into even some Ballanced audio cables....A Power conditioner will help get rid of AC hum and Ground noise and also help get rid of the noise caused from Effects pedals that run off of AC/DC Adapters as they are a source of audio noise.....

I don"t think the Delta card it"s self will put off any noise as it"s Noise specs are quite good and shouldn"t even be noticeable....
You might also check the wireing in your House as Bad wireing will cause all sorts of electronic noise.....

I guess you could also coat your studio and all your equipment in a sheet of Lead (Not even Superman can see through lead)....LOL... :D


Good Luck
 
hahah nice, thanks..

I am going to take one of the speaker to another room and plug it in to the wall and see if it makes noise just by itself, I think I may also attempt borrowing someones UPS backup battery and see if i get any noise from that. I want to make sure its not the speakers making the noise.

is a power conditioner a good thing to invest in?
 
Rule of thumb: Monitors go on last and off first in the power chain.
 
The main problem is that all i have for volume control is my software that came with the Delta (since I have no other audio card) and so my volumed are all controlled through that software, and when I shut my computer down, it pops at a volume unaffected by the software.. I think I need to get an external volume controller... or something... It has popped twice like that, did I break anything, and how can I check if anythings damageD?
 
Don"t your Monitors have a Volume controll knob on the Front or back?? That is what I use to controll the volume and all Powered monitors should have a Volume knob ,and Passive monitors won"t have a Volume as they use an external power amp.....

A power conditioner is good if you get a lot of AC hum in your signal and if you use a Lot of AC/DC adapters for pedals they really help get rid of the noise they create unless the Problem is within the Electronics of the Unit it"s self....

Cheers
 
they do have a volume on the back but you have to adjust it with a screw driver. and tht would be more work than its worth...
 
The only way to really know if something was damaged is by listening. If you can't tell then everything must be good. :D I've been there with the whole poppin thing. I dealt with it until I picked up a Presonus HP4 from the Free Ads thread here. I should have got one long ago. It's a very decent headphone amp and I love having it's seperate volume control (with mute button). As far as the hum/buzz, I still experience that although mine is intermittent. Dgatwood mentioned something in a post that you may want to read. I'm going to give it a try as soon as I get a spool of 10 guage wire. Here is the thread:

Good solution is to turn the speakers off FIRST. :) A power strip helps.

Failing that, you could slap the designer of your sound card repeatedly. That's probably either an indication of a DC offset or an indication that the circuit goes way unstable as the voltage drops. Either way, the sound card manufacturer should be slapped repeatedly with a wet noodle.

BTW, a DC offset may be helped through better grounding, depending on the cause.
 
here is my trouble shooting.

1. Unplug signal cable, so the speakers only connection is a power connection, I can hear a slight buzz still.

2. Move speaker somewhere else in my room and plug it in away from all the junk on my desk, still same buzz

3. move further away, down the hall, still buzz when turned on,

4. into living room, still has buzz..


So i am assuming that the buzz is within the speakers..

I do get a much louder buzz when i plug my balanced cable from my keyboard into the Delta 44, Might this be a ground loop problem?
 
By the way, I also picked up a Presonus headphone amp and am using that to combat the speaker poping problem, working so far AND I have a way to control the volume now.
 
I'm not sure if it would help but try using different power cables. I don't know too much about electricity but who knows, could work.

Also, what are you using for an interface? or What are the speakers plugged into? Make sure that the speakers and whatever they are plugged into are on the same circuit/fuse. I had a problem with an amp making noise and it was because the amp and interface were not on the same circuit. Very odd, but it worked fine when I had them on the same circuit
 
If you are getting a funny staticy noise it may be coming from your pc. I've had this before. Try runing something CPU or graphic intensive with the monitors switched on and see if it gets worse. Like a game or something. That used to happen to me. However for some reason I recently plugged my pc into a different power outlet and the problem seemed to go away.
 
Hmm I've got into the same 'problem' with my pair of KRK RP6. Tried various plug-ins, with no signal cables and it's still the same. A number of things I've found:

- light dimmer should not be used
- beware of wall-warts (transformers for various equipment) - don't place em anywhere near signal cables
- a voltage regulated power supply ($$$) will help but not always

The conclusion I got is, if it is 2-4 inches, it's ok, but if you still hear it 2-4 feet (sitting position), then that's a problem. Some of the hiss is just not possible to get rid of in a usual household with that much power cables and other wires running everywhere.
