Think I may have blown one of my studio monitors.?

[bubinga5]

I plugged the bass straight into the back of the monitor. It sort of popped, now it just makes a squeeling noise when I turn it up. Have I blown the speaker or what.?

[JTUK]

Not sure I'd ever do that.... but the squeeling noise doesn't sound like the woofer itself..?? normally too much signal goes right to the cone and its movement.

You're good for a visit to a repair centre for the monitors to get an estimate, I'd say. Put it down to experience and don't do that again once it's repaired.

Might be good as a 1st step to do a check like this [url="https://youtu.be/oharywNa044"]https://youtu.be/oharywNa044[/url] then do the same to the other good monitor ( if you have a stereo pair) and compare any difference ?
If the monitor has a standard jack input, just plug a guitar lead in and touch the 9 volt battery across the ends, tip and ring is it called ?, of the other jack plug.
You need to know if the speaker has blown or maybe a fault on the amp could be causing the squealing noise.

Take it you mean the bass amp plugged into the monitor ?

Its only one monitor thats faulty. The other one was fine.

No i plugged bass straight into the monitor via 1/4 inch jack. I'm an idiot.

Ok tried that test and the speaker cone moves.

With the best will in the world, I find it hard to dispute that 😜😘

We have to presume that these are active monitors..? If that's the case, the second one has not suffered at all. Only one to get fixed, then..?

What monitors are they ? What bass is it? Did you plug the bass guitar into one active monitor ?
It's fine to check the speaker itself as in the method in the Yoube video, but don't put a 9 volt battery into the input of a powered monitor.
You need to tell us a bit more than " bass into monitor". An active bass into a powered monitor could well blow the speaker. Sounds likely that's what has happened

It's disappointing this error could take out a monitor. A signal from an active bass should just clip, not cause damage.

[ivansc]

As my dad used to say, "Well you wont do THAT again in a hurry, will you?"

[Phil Starr]

It's hard to say without more information. It squeals when turned up. Does it do this when there is no signal which would indicate damage to the amp inside, or when you are playing music(not bass) through it. Does it play music when you have it turned down but distorts when you turn up? That would indicate the amp is probably working OK but something mechanical has gone wrong with the speaker.

I thought active monitors would take line level input, which means that a signal from a bass (active or passive) shouldn't even touch the sides, let alone clip.

[MoonBassAlpha]

Well, line level is about 1V P-P and I'd think an active bass running off 9 or 18V would be able to exceed 1V p-p.

[tauzero]

The output from an active bass is similar to that of a passive bass, somewhere around 150mV P-P.

[/quote]Well I'm not sure about music as my Macs charger has broken so no Mac. It will squeeling when bass is plugged in obviously. I can't say for any other source. I know of a guy who fixes guitar amp,s etc. I wonder if could have a look at it

There's a Richer Sounds in Cheltenham; I'd suggest taking it to them.

They'll certainly know how best to get it repaired, I reckon. Edited November 11, 2018 by Dad3353
