live PROBLEMS LIVE SETTINGS: WHISTLE - NOISE

[Pull-OH]

Hi everyone!
I am a begginer with PODHD 500x, that's why I need your help.

I dowloaded differents patches from the LINE 6 website, and when I tried them at home everything worked fine.
When I went to play with my band in our small room, I attached the POD direct in front of a combo (LINE 6 SPIDER IV - CLEAN).

Problem is that when I play a distorted patch, it start to whistle and make unsupportable noise.

I read on http://foobazaar.com/podhd/toneGuide/setup
This that I report:
"I recommend setting your output mode to the appropriate non-"Studio/Direct" mode. If you want to use your Pod for both "direct" and "live" purposes, I recommend leaving the output mode as "Studio/Direct" and setting your "live" patches up with "no cab" as your cabinet selection. When you use "no cab", you get the same output in every output mode (more-or-less) - all cab/mic simulation is simply disabled. "

 

Now what I would like to try is to set INPUT 1: GUITAR and INPUT 2: VARIAX for all the patches;
And then I would like to put this "no cab" suggested, but I don't really understand how to do this.

About the "mixer" Path A and Path B should be Centered ? Or should I leave it 100%R and 100%L?

May you help me through this? Any other reccomandations?

Question, and you probably can't answer this since you're not live anymore, but does the squeal go away when you unplug the guitar?

Turn down the amp. Make sure your combo is not adding lots of gain.

Lower the gain in the HD.

Use a noisegate. .Sounds like your pickups are polyphonic.

Shielding the guitar is worthwhile and will minimize the squeel.

Turn it down. Move away from in front of the amp speaker.
