monitor buzz

[thrillhouse1970]

I've had a pair of Alesis M1 Actives for over a year and a half, and I've been pretty happy with them. Just today I'm noticing a mild "buzz" coming from the tweeter of my left monitor. This buzz maintains a constant level, even with no signal going into the monitor and with the input knob on the back turned down to zero. The monitor performs fine, otherwise.

If you're "normal listening distance away," you can barely notice it; but it's pretty audible if you're a foot away. The other monitor sounds fine.

Anybody have any experience with this issue, and how can I fix it? Do I need a new tweeter?

Thanks!

Yo House of Thrills in 1970:

Check your cables. Switch the cables from the "good" speaker to the buzzing one and see what happens.

If you're only getting a buzz in one speaker, I've got to bet it's the cable. Maybe I'm wrong but if it were internal with another piece of gear, you would, most likely, be getting the buzz in Both speakers.

Usually the term "buzz" refers to a low freq, typically 60 hZ. Not likely to come out of a healthy tweeter. Are you sure it's coming out of the tweeter and not the woof, or is it a higher, tinny kind of sound that caused you to use the term "buzz" ?

Also, when you say no signal, do you mean just turned down, or no wires connected other than power?

Any unusual circumstances recently, like pushing the wrong button and getting feedback, or anything else you can think of?

Normally a tweet won't make noise if it's broken, unless there's a signal going to it.

Try actually disconnecting the input cable at the monitor but leaving the monitor's power on, and see if the noise is still there.

Post back with as many answers to the above as you can, and we'll take it from there... Steve

It's not likely, but you could have a cap on the crossover heading south.

I have the same exact problem with my Behringer Truth B2301A's.
Even with no cable plugged in, one of the tweeters has a "buzz" to it. Not a power line hum, a buzz. If the speaker is turned on, it buzzes in the tweeter. I tried switching power cables and plugging it into different outlets.
Is there anything I should try to do before sending the unit off to repair?

it probably doesnt need to be repaired try the speakers out using differnet connections try it not hooked up to your mixer/interface go directly through your pc/mac soundcard. That elimated a lot of buzz for me for some reason when I put it through my tascam fw-1082 it buzzed liek hell to the point where it was unbareable.
