All patches produce 'clipping' even when set clean...

Hello! I'm the proud and now frustrated owner of the new Helix.

 

The problem I've been having is 'clipping' which is coming through the headphone out. I've upgraded my headphones to a set of Beyerdynamic DT 770 high impedance but the clipping still persists.

 

Is there a global setting I'm missing? Even turning down the volume on my guitar doesn't sure the problem.

 

Fingers crossed it's something I can tweak within the settings!

 

Many thanks in advance...

 

And I've just updated the firmware but no luck there.!

Is the clipping coming through the XLR outs too? Where is the headphone volume set? Try a factory clean patch and make sure its not something wrong with the gain staging in the patch you're using. Disable all blocks in the patch and see if that's still distorting.

 

If its only through the headphone output, then there's likely something wrong with the headphone amplifier. If its coming out of everything, try a different input.

Hi, thanks for the advice.

 

I've just played the factory presets through  a 1/4 inch cable to one of my Alesis active speakers and I'm still getting the 'fizz' which is really pronounced on any setting that has some gain.

 

I have tested a variety of guitars, single coils, humbuckers and the clipping happend regardless. I've also played with the guitar impedance and guitar 'pad' settings but to no avail....

 

If it had tubes, I'd swap them out ha ha!

 

Any more suggestions would be appreciated, but am coming to the conclusion I'm going to have to return it. Groan.

This is interesting because the first thing I thought it was that the headphone output is kind of low. I have to set the phone level to about 2 o'clock to get a comfort level. And my Sennheiser HD280 are 64 Ohms. With higher Ohm Headphone it would be even lower volume I guess.

 

From the manual I see that the Headphone output is 12 Ohms. Reading the note at page 8 of the manual it says:

 

NOTE: Helix provides plenty of gain for high impedance headphones. With lower impedance headphones, you may notice a bit of distortion if the PHONES knob is turned all the way up. This is normal.

 

So you may try to use some headphones with higher impendance.
