Shutting off powered monitors

[zbert]

I have a pair of Event PS6's. At the end of my recording session I turn down all the volumes on the board. I shut down the monitors first but I get a pretty loud "pop" when powering down. I talked to a another friend with powered monitors and he said he has the same problem. Are we doing something wrong?
Thanks

Yeah - when I had PS-6s they did the same thing, even though they were the first thing I shut off....

It never seemed to harm them - but it sure sounded like it would....

I don't know why they didn't incorporate a mute circuit there, seems like an easy way to blow a tweeter....

I replaced the PS6s several months after I got them anyways, so I never ended up worrying about it...

Maybe you should ask Event tech support?!

I have the Event 20/20 Bas's and I find you have to shut off the AD/DA converter first, then power down the monitors. No pop if you do it that way.

I don't have a converter as I record to 2 DA38's but I did take the suggestion and write event. This is the quick reply I got...

Hello, and thank you for your support. I am very glad to hear that you are satisfied with the sound of your PS6s (they are sweet aren't they?!!?) I just wanted to address your question about the PS6s popping when you power them down. Mine do the same thing. There is nothing wrong with your monitors, but there my be a few things you can do to try to eliminate this, as it would seem to me (having some experience with this) that the problem is most likely a not so good power source. You can clean up a bit by implementing a power conditioner in your power grid, or possibly just using a power strip to turn them on and off can also help out a bit. I have found out over time that the worse your power source, and the more disorganized your power wires, and audio wires get the nastier this type of artifacts can get. Make sure you are using the best balanced cables as possible, and of course avoid running power cords parallel to any audio cords. Try to find the cleanest power source you can find, and avoid having any lights of any sort connected to the same power grid. Moreover I think just using a power strip to power on and off should alleviate your popping to some extent. Thanks again for your support!

Cheers!

Sorry - that's a load of doubeltalk! Well - not invalid, but not likely the cause of the problem...

I know this because I was running completely balanced power at the time (via pricey Furman IT1210 balanced xformers) and they still popped...

I'd press them for a better answer....

I have Trias and I get the pop too. Sounds like that response came from a salesman and not a tech!

Lights of any sort??? An incandescent lamp can cause "artifacts"??? I sincerely doubt that one. It's a fucking resistor!

[zbert]

I gotta go with your idea it's a bad resistor or something like that. I can say that I did start to power them down by shutting off the power strip instead of the speakers and the pop is not as bad. I got a good place near me for electronic repairs on musical equiptment. I'll drop the speaker by him and have him check the guts.
Thanks guys!

For what it's worth, my reply from "Q" was a little different. I'm not positive that his/her email makes sense with the whole "transient protection system" but I do use a power conditioner and I think my cabling is reasonable. Whenever I power off, it sounds like I'm plugging a guitar into a cranked Marshall. It seems to me that if the monitor is the first thing I turn off, it shouldn't pop.

Here's the email:

Hello Chip, and thank you for supporting Event Electronics. I just wanted to respond to your question regarding the popping of your PS6 monitors on power down. I can suggest a couple of things. Firstly I would suggest taking a bit more time when turning off your gear in your studio. The PS series monitors are equipped with a pretty good transient protection system, however once it has been tripped (most usually by another device or the other monitor) the protection system needs around 40 seconds to reset. The other thing I can suggest is to use a power conditioner/power strip to power on and off your monitors. This can sometime really reduce the transient strength that gets sent through your system. Also, sometimes some better audio cables can really help eliminate unwanted noises from your system.
Almost never has this problem actually been the cause of any type of problem with your monitors. So I wouldn't really worry too much about this. Just be careful not to put your ears right next to the monitor when you are powering on/off the monitors!

Cheers!

Are the connection between the monitors and the mixer/whatever balanced?

If not it could be an offset voltage from the output too.

They were when I used them... and it still did it.
