I have got one of those creative soundbalster 5.1 cards in my computer connected up to a creative surround sound amp thingy with all the speakers etc.

It sounds good for games etc, but I wanted to give it a bit more oompf so I connected a pair of mission speakers up the the left and right channels and it sounded ok.

Now I can't get a carrot out of the left channel so I think I may have buggered something inside the amp by putting too big a speaker on it.

Question is, will there be a fuse inside the amp I can change?



I will post up the model of the amp up later when I get home.

cheers,

mike.

Most amps used to have protection fuses on them - it was the norm to have them accessible on the outside.

It may be worth whipping the top off and checking for quick blow glass type fuses, and replacing with EXACTLY THE SAME as you take out. (They are rated that way for a reason!)

What's the make and model of the amp?

Cheers,

Really, you should know by now that unless you spend HOURS with a spirit level, you'll never get sound out of your speakers.

Do u have this system Creative® Inspire™ 5.1 Digital 5700


So do I - they are sooo good and are still £250 from CREATIVE

I would not of thought u would have blown a fuse inside it. what connectors r u using to connect the speakers up to? Have u set the options on the front of the amp/box to the right settings
Effect>Stereo
Digital PCM Audio> Line in or
Digital PCM Audio> Digital DIN


Btw, what do u want to up the power of the outstanding speaker system??
they go loud enough for me and i would say too loud for me if i turn the vol dial up to max mark.

Hope that helps

what would scooby do

I assume you have put the old speaker back on the left channel to ensure it is the amp and not the speaker.

I've no idea what impedance the creative amp likes so I wouldn't risk banging on 3rtd party speakers.

I use the 5500 digital system (£80 new on ebay)

oooops, bit too late

mission 7611's.

cheers peeps, anything constructive?

Most modern amps have solid state protection.

You don't often get fuse protection nowdays.

On cheaper stuff especially PC based stuff you get only the simplest of protection circuits.
A Creative amp pushing out 7W RMS is going to be seriously overloaded trying to drive some proper hifi speakers. My money is on the amp on that channel being buggered.

Sorry

cheers lee, I was thinking along the same lines, I might have a tinker with later on the offchance there are fuses.

When you say solid state protection, will there likeley be a single component that could have failed?

cheers,

mike.

At the price range we are talking I would suspect the amp having only short circuit and open circuit protection. You would be looking at some sort of zenner network for protection so nothing you can reset.
In an overload situation some part of the amp stage is probably going to get very hot and burn out.

Is it worth getting it repaired though?
Richer Sounds have Pioneer AV amps for sale for £80 and have DD, DTS, Dolby Pro-Logic2 and 40w per channel.

tTo be honest If it wasn't something that I could repair myself I wouldn't bother - my electronic repair skills are limited to taking something to bits and looking for components that look knackered - if theres nothing obvious it'll go in the bin.


Now then, as an alternative, I have a NAD 3020 integrated amp that is just sitting idle at the moment, cost me a small fortune years ago!

could I connect my PC soundcard to an input on the NAD amp, and then drive the mision speakers that way?

my only concern is that the input of the NAD amp could overload the output of my PC soundcard

I realise I loose all the surround sound stuff, which I must admit is feckin brilliant for PC games, but I can live with that at the moment.
any thoughts?

thanks,

mike.

logiclee

That's OK, use the line out on the sound card to drive one of the NADs inputs.

The amp doesn't present any load to the sound card.

Cheers

errr, it wasn't the amp. There was a loose connection inside the left mission speaker

sod it, wired the job lot up, now officially defeaning, I'd forgotten how loud this lot is

the only problem is that my sound card won't feed both the 5.1 amp and my NAD at the same time would have been a bit noisy

MJ, have you tried one of those 1 into 2 splitter jacks? That will allow you to run two stereo inputs from your sound card output mini-jack.
