Potential Power Amp Damage

Hi,

I recently purchased the Kemper Powerhead.

I absentmindedly plugged the Speaker Output of the Kemper into a 'Line6 Spider' Guitar Amplifier. This was for a brief period and I only played very briefly through it before realising my error. I'm worried I may have damaged the Power Amp / Speaker Output.

I have subsequently plugged the Speaker Output to an unpowered Cabinet and things seem fine but I've not used the Speaker Output before and I'm not entirely sure what I should be looking out for with regards to damage.

Also, will using damaged XLR/Jack leads on the Monitor Output and Main Output potentially damage these outputs? This happened to me on a show recently and it was out of my control to resolve the situation.

Many thanks

I think the only thing you would have potentially damaged was the line 6 As long as you didnt hit the front end of the line 6 too hard you should be ok.

You basically put a huge boost pedal into the line 6

yeah def when something is damaged it would be the line 6

Thanks! The Line 6 was just some ropey house amp so I'm not bothered about that!

As long as I haven't damaged the KPA. I'm guessing I'd know about it if I blew the Power Amp? I assuming it either goes or it doesn't, it's not really a gradual thing?

There is no way you would have damaged it. All the output sees is something to go into to make sound.

Why would you use damaged cables ?????

Repair or reject !

Cheers !

Not my cables........was a slightly dodgy venue......didn't realise until halfway through the set when the signal was cutting out and wasn't able to switch them!

I agree, chuck them immediately........but there is no risk danger in damaging anything at the KPA end is there?

Cheers

Well , short circuit is not healthy to any electronics

And with gadgets with hefty price tags like Kemper I

would really make sure that I use my own hi quality cables .....

Just sayin´ .......

Cheers !

I've checked all the outputs and everything seems fine. I'm assuming I got away with it??

Make sure you don't connect the SPEAKER OUTPUT of the PROFILER with any grounded equipment!

From the Main Manual:

¨ WARNING!

Never connect an active device to the power amp output! Any active devices (such as power soaks) that have a grounded circuit will destroy the power amp by creating a short circuit.

Only passive speaker systems should be connected to the SPEAKER OUTPUT.

Thanks Burkhard. Given the Power Amp seems to be working fine it looks like I got away with it.......There doesn't seem to be any damage. Could there be any partially damaged or any anything like that?

Burkhard · February 10, 2020 at 2:45 PM

I don't think so!
