Just bought a pair of Truth B2031A monitors.

I know that there have been some negative opinions on these monitors (Behringer Truth B2031A), but I really wanted some 'active' monitors, and these (purchased used, from Guitar Center) were all that I could presently afford. I was informed that one of the GC workers had purchased this set, and brought them in for sale after experiencing some raido station intrusions from them. I thought that I could get some type of line-filtering device, if I encountered the same problem, but nothing of the sort has surfaced as yet. There are, however, two situations that I am finding with them:

(1) Whenever the monitors are powered on, there is a loud staticy noise from both monitors for about 10-15 seconds. And (2) there are times when one of the monitors will lose power. The green power light will die out, and my answer to this is to position the power switch into the 'off' position - then back to the 'on' position.

I wondered if anyone else has experienced the same, and (if so) could enlighten me as to what it is due to. I hope it isn't to mean that the circuitry is about to die out.

Sounds like you might have bought yourself some defective monitors. They should never just power off like that. Also, as far as I know, you shouldn't get much interference, as most Berri monitors are shielded.

1 the 2031As are shielded, so you shouldn't be expecting to hear external interference. If you do, it is possible that the cause is not the monitors, but the cabling to the monitors. That would be a good place to start looking.

2 noise on start up . . . I can't offer any ideas on this

3 powering down . . . if the 2031As are like the 2031s, then they have a 'sleep' setting on the back. If this is set,the monitors will power down after a period of non-use, or during a period of use where levels are low. Again, this would be the first place to start looking.

Try using xlr cables to connect the monitors with balance 1/4" to your soundcard. The only thing that I know of that could cause noise at start up is to turn your monitors off before you shut down your computer or even put it to sleep and turn them on after you have your computer turned on.
hope that helps.

Thanks Gecko,

You have made me feel a great deal better. I hadn't even begun to mess with the 'switch-settings' on the rear of the cabinets. But, just after reading your response, I did find that the 'power mode' switch (on the rear of the monitor which was shutting down) was in the 'auto' position. I set it to the 'on' position (which is where it is set on the other monitor) and, hopefully, all will indeed be well.

I appreciate you.

Hello CSM,

I just wanted to add that I don't even have these monitors integrated with my computer, as yet. They are presently set up with my MotifES7 synth, and I always turn on the monitors before powering on my synth - and shutting down the monitors before powering the ES7 off. I also forgot to mention, in my first post, that it (the static) doesn't always happen at startup - just most of the time right after powering the monitors on. As also stated, that staticy period is a rather short one (lasting for no more than 10-15 seconds), and never occurs during usage, or when powering down. Maybe it is really nothing, and will work itself out with time (I hope so, anyway ).

Thanks to all for responding.

Last spring I bought a brand new set of KRK RP5 monitors. After about two months of use, I had a similar static issue developing in one of the speakers. I never did get to the bottom of the problem since I'm now living in Korea, and couldn't bring my recording gear with me. They're packed away at home, though, so if anyone does happen to have a suggestion as to what could cause this short burst of static that the original poster and I seem to be experiencing, some input would be appreciated. Otherwise, I guess I'll just contact KRK when I go home for good.

Hey Brandont_h,

I never did get to the root of the problem - regarding that staticy noise on startup, with my monitors but (unlike your singular issue) my problem emanates from both speakers - and only at startupup. I have found, however, that powering on my synth first - and then putting my monitors into operation, helps to reduce the frequency of it. But it does still happen. I have heard nothing back, from Behringer, on this matter - and have resigned myself to the very probable fact that I won't. But it isn't a 'lasting' condition (only about 10-15 seconds, or so), and I think that I can learn to live with it. I hope that you have better luck with your KRK's (which is what I would have purchased, had my pocket been right enough).

[brandont_h]

Yeah, in my opinion (and in the opinions of many, many others, I think) you should ALWAYS turn the monitors on last, and turn them off first. I've always done that with these monitors. I've never run a weird signal to them either. Like your Behringer problem, it was only when I first turned the speaker on, and usually less than 5 seconds long.

I'm thinking about having my friend ship them to me here in Seoul, since I have an opportunity to help make a couple of records. I guess if the problem is still happening, I'll contact KRK for help.

Good luck!

i've been using a pair of Truth monitors for over 3 years and have not experienced any problems with them.
with my monitors, if i am to turn them off and back on within a certain amount of time (say ten minutes or so) - there will initially be a "POP" but no static. i believe this is caused by the capacitor inside of the amplifier, because it hasn't had enough time to drain. that may be what is causing your static.
if so then it's nothing to worry about.
