Dead Amp!

Does this sound (A) Terminal

(B) Expensive

© Stop messing about and buy a new one?

 

Warrior IS600 amplifier, approx 6 years old, bought new initially. When power switch is turned on, there is a click from the amp, the fan keeps running but there is no sound output. (power on indicator light bulb blew ages ago, so there are no visual clues.)

 

 

Is it repairable? Is it worth it at that age?

 

The only reason i ask is that if anyone has experienced a problem like this and it turned out to be nothing more than a blown fuse....................

 

 

Thanks in advance for your comments.

Sorry for the 3 posts, my laptop is misbehaving somewhat!

Well, strange that it's both channels I suppose. The IS range tend to suffer from incredible dry joints on the power section.

If you pop the top off you might also find 2 largish resistors that get rather hot and either go o/c or melt their solder off.

Thanks for that. To be perfectly honest, as I was typing my question out, it got me thinking that I should replace it anyway. I probably would not trust it again anyway. It's amazing how writing something down helps you to think more clearly!

 

 

Thanks anyway, eBay here I come!

Ok. Further to my Dead amp problem.....

 

I have bought a new amp. Still got the same problem. No output to my top speakers. I recently bought a crossover.........could this be the culprit? I know all 4 speakers work. When the problem raised its ugly head originally i was setting up for a gig, so being short for time, i plugged the speakers directly into the amp (as before the cross over was fitted) and it worked. (albeit i only used two speakers ASSUMING that one of my amps had died....) MMMMMM....

 

So, is my best course of action to check that the new amp, my other newish amp and all 4 speakers work ok by not bothering to have the crossover in line? (Process of elimination i suppose.) The more i think about it, the more i think i bet its the bloody crossover.

 

Have also noticed, with the crossover wired in, that on the mixer (behringer VMX1000) that the main volume indicators LED's do not light up. (The input leds work ok). Although when i bypassed the crossover they did light up.

 

 

Its the bloody crossover isn't it?????

 

 

 

If i am right, then at least i will have a spare amp!! Which reminds me, i will see if that works too, thinking about it, it might be ok perhaps.........

 

 

 

Comments welcome!

 

 

I will report back when i have tested it.....

How are you wiring in the crossover to the mixer?

 

You should be going Mixer (Main Out) -> Crossover -> Amps

 

 

It could be you also have some of the output channels muted? give us a bit more info on the crossover (make/model) and how you've wired it in.

 

Cheers,

Sorry for quote reply with no reply attached, bloody Iphone!

 

Anyway, yes it is all connected properly (mixer mains to crossover, crossover to amps. Low signals to subwoofer amp and highs to mid range speakers amp.) It has actually worked in the past, sounded very good as well!

 

The cross over is an L2 Audio X0223V item and it is about 2 months old, its been used twice.

 

I am going to check that everything works as it should directly from each of the amps, that should then tell me that it is the crossover unit that is faulty and not something else (hopefully).

 

Sounds to me like the high output side of the crossover has gone belly up. (Am getting a signal from the low outputs no problem.)

Well, I have now found the fault. A pair of faulty cables. A pair! There must be only me and mr unlucky of sods lawville who this could happen to....has anybody else had two cables ( xlr patch leads, xlr one end, jack the other) go down at the same time, leading you to think that it must be equipment failure? Aren't I blessed? Dear me I do not believe it.

Well done for sorting it out! Now you can breathe a bit more easily that your Amp is OK..

 

And now you have a spare AMP as backup should either of them go *bang* ! :)

Yes, i now have a spare amp! Oh well, i often thought about getting a spare one anyway just in case....

 

 

And the moral of this story is?

 

 

BUY NEW CABLES PERIODICALLY AS THEY DO NOT LAST FOREVER!!! And buy some spares too!

 

 

The thing that helped me most in order to fault find, was a paragraph from an article i found on the internet, which was very simple and obvious.

 

"Unplug everything except the speakers. Start with the source of the music and make sure that is giving an output, then carry on connecting/adding your components and cables until the music does not get to the speakers anymore. Its a good bet that the last thing you connected is faulty/incorrectly adjusted/ switched off!!"

 

Simple i know, but if you follow that train of thought it really helps. Especially when you are technically inept like me!!
