Hd500+microphone Problem

[DeadGuitarz]

So I'm trying to run my HD500 to my amp which is micced with a Shure Beta57 running back into my pedal which is connected to my laptop via usb. as soon as I switch the 2nd input to microphone I get high feedback (even with the Mic turned all the way down). Pleases help!! Idk what else to do!!

Sounds like your trying to reamp all at the same time, check out some videos about reamping.

 

* Orignally I said try starting with the mixer levels at 0 and working up, I haven't tried this though. It doesn't sound like it's going to work.

You have created a perfect feedback loop which is why you get feedback.   You have the mic in front of your amp but running back into the HD500 - then you have the output of the HD500 running into the amp - which gets picked up by the mic and sends it through the HD500 to the amp etc etc etc - instant feedback.

So I would highly recommend that you don't do it as you are just going to damage your gear.

 

Anyway, what exactly are you trying to achieve by placing the mic in front of your amp and then feeding it back to the HD500?

[DeadGuitarz]

The idea was to get a micced sound and as well as a direct in. I thought this could be done seeing as it had a Mic input. I also do not have any other interface to my computer other than the HD500.

The amp models on the HD500 provide you with speaker and mic modelling as well when you have STUDIO/DIRECT output mode selected - so if you want a mic'd amp sound to record then just use an amp model and don't use your physical amp.

.

Or do you not want to use the HD500 amp models? Is your intention to just use the HD500 fx and then pick up your own amp's mic'd sound which you will then record via the USB interface of the HD500?

You CAN get a mic'd sound as well as a direct in, but you can't send that signal back out your amp or you'll get the feedback loop. This is not an HD500 issue. It'll happen with any effects unit. Listen to it thru headphones or record it in your DAW.

You can achieve exactly what you are trying to do; here is what to do:

 

set up dual inputs paths on the HD500. make input 1 guitar, make input 2 mic.

create a dual amp path, leave the bottom path as "no amp", set the top path as the amp model you want to use to go to your actual amp.

 

make sure ALL fx blocks are moved into the TOP amp channel path - leave NONE in the 'pre' single position before the amp splitter. Same goes for post FX - move ALL post FX into the top amp path.

 

You should now have your signal that would go to the amp in the top amp path, and nothing in the bottom amp path.

 

Go to the mixer settings, and pan them both hard Left and Right.

 

Connect the left 1/4" out from the POD to the FX return of your amp.

Put your HD500 in "combo/poweramp" mode. This will disable the mic modelling.

 

I *don't think* you would need to place a "dummy" 1/4" cable into the right output of the POD, but you *might* need to, so it doesn't do a mono sum of the two channels and cause that feedback.

 

If you prefer, another option would be "Studio Direct", which would include mic modelling; though that won't create an ideal signal for your SM57 mic. So for now, lets stick with the Combo/Poweramp mode.

 

One note to that - not sure how those output modes impact the mic signal, since you are not running it through an amp or processing it. You may want to try both, and see if one sounds any better than the other.

 

Last, go into the mixer section, and increase the level of path B until you get decent levels in your recording software.

 

A note on output modes - if you end up in Studio/Direct, you can get a decent recording ready signal from the path A as well as the mic in path B - but if you are in combo/poweramp, etc - any mode other than studio/direct, don't even bother recording that input path A, it will be configured to sound good through your amp only, and won't translate well to recording.

 

Essentially arm the recording software to a mono track and record of the 1/2 pair, 2 only.

 

Here is a sample patch; I created this offline, so you'd need to tweak the FX and amp model choice, settings to what you want to do with your tone. I boosted that mic input 2 level +6db in the mixer; you may need to adjust that to less or more, depending.

Hey Co-lo-nel, I'm going to have to try that someday. I downloaded your patch. Nice rundown Thanks.

[DeadGuitarz]

Thanks Colonel! I am about to try this! I had it going at one point during my many tweakingsm and didn't save the settings. Came back to it and it was gone. I had amps set to both channels which I'm sure was my problem now! Can't seem to find the mono switch in my recording software (acid pro 8) so I will try the first set up. And thanks for the tip on turning the Mic simulator off as I had no clue how to do that either. This is all for more depth and realism. I will let you know how it turns out :]

The simulations sound great and all but Mic positioning and real world tweaks add more realism and depth in my opinion. You can't get any "in between" positioning with the Mic settings in the pedal.

So I did your troubleshoot rundown and got it going in the right direction. I did not have to plug in a dummy 1/4 jack which was nice btw. So helpful, thank you very much! With that being said I did notice the "weakness" of the Mic signal even with the B channel turned all the way up in the mixer. I also messed with the physical knob on the connections side of the pedal which didn't really do much for the problem, odd.

You can boost the mic signal path by using the VINTAGE MIC PRE model in the lower path after the split before the mixer.  You will find it in the EQ model bank.  It will allow you to add gain to the mic signal before the mixer just like a stand alone mic pre-amp would do, as well as adding vintage pre-amp warmth to the signal apparently.   In fact there are several EQ models that will allow you to boost the gain prior to the mixer - so just pick the one you prefer that gets you the result you are after.

Hahaaaaa! I assumed correctly! I was messing with it all last night for a while and after taking a break I thought about this. Trying it today when I get home. You guys are awesome thank you all so much for the help!! \m/

Sometimes when you take a break and let it all sink in, the learing process works it's best, Thomas Edison, had a little room with a chair a table and a paper and pencil. He would sit there in silence and grab ideas from the air. Thus the lightbulb that hangs over someones head when they get and idea, LOL.

 

I'm glad you brought up this thread 'cause I wanted to do this in the future. I knew it should be possible since there are 2 seperate channels in the pod if they're set up correctly. Anyway, hope it works good for ya.
