TC Electronic RH750 Break Up SORTED

[Open E]

I'm experiencing signal break up on my TC Electronic RH750.

I've checked the gain setting isn't too high and have no effects selected on the amp.

I switch to another amp and it goes away so can't be the cab or the bass.

It sounds like a distortion that not part of the bass signal ie, not like a regular dialled in distortion.

Any ideas out there?

It could be that you're just running out of headroom. The RH heads are not that powerful .

I've weirdly had this same thing happen recently with my BH550. (Random bouts of heavily distorted tone that clear up after a few seconds, on multiple different basses). My feeling is, being a class D amp, whatever it ends up being, it's likely not going to be cost effective to fix, so just bring my back up to gigs and when it dies, it dies!

Not sure this is a factor. I know they have the well known TC issue with deceiving power numbers, in reality the amps have plenty of juice.

 

I have used an RH750 as a power amp many times and it go's stupid loud and stays clean.

A couple of hundred watts only takes you so far even if it "Sounds like 750W."

It’s actually happening at low volume so a bit of a mystery.

[BassmanPaul]

Turn your bass down and the amp up as required.

@Open E did my last suggestion help? 

[Open E]

It’s happening at really low volumes so don’t think it’s a  high signal problem. I’ve stopped using the amp.

thanks for your suggestion.

How?

What was it causing the fault.

[Open E]

Loose speaker connection

7 months of problems caused by a loose cable, how painful!
