afraz87 Posted February 2 Share Posted February 2 Hey guys, I'm trying out different approaches to create a patch which allows me to connect to both FOH and an onstage amp (via FX return). One of the approaches I am trying is: MAIN L/R -> DIST -> AMP -> SPLIT -> DELAY & REVERB IN PARALLEL -> MERGE -> SEND L -> IR -> EQ -> MAIN L/R Main output L is going to FOH and Send L is going into FX Return of an EVH 5150 I've seen this work in a lot of videos and posts here but when I do this there is a very loud noise that comes from my speaker cabinet, at earsplitting loud levels. I don't know if its feedback or what. The FX Return of the amp is fine by itself, ive tried 4CM and that works perfectly fine. Any ideas what i'm doing wrong?

Schmalle Posted February 2 Share Posted February 2 Does the noise from the amp disappear when FOH is not connected? Does the noise disappear if you bypass Dist and Amp blocks? 1 Quote Link to comment Share on other sites More sharing options...
DunedinDragon Posted February 2 Share Posted February 2 To each their own but this runs counter-intuitive to the notion that the audience should hear the same tone and mix that you're producing on stage. 1 Quote Link to comment Share on other sites More sharing options...
afraz87 Posted February 2 Author Share Posted February 2 I found the issue. But not sure I understand it. I turned down the send level to -50DB and now its at a non ear shattering level. But im not sure if this is whats meant to happen. Setting it that low sounds a bit silly. Is send meant to be WAY louder than normal output? I wonder if send is meant to be the equivalent of the master knob turned up all the way. Quote Link to comment Share on other sites More sharing options...

Yes, the volume knob is subtractive unless it is cranked. 1 Quote Link to comment Share on other sites More sharing options...

What signal level are you sending and what signal level is expected in your amp? 1 Quote Link to comment Share on other sites More sharing options...

THIS^^^ A quick look at the manual (5150III) indicates that it expects INSTRUMENT level. Most modern amps expect that. 1 Quote Link to comment Share on other sites More sharing options...

All output levels are sent to Instrument. For the MAIN L/Rs as well as SEND. Quote Link to comment Share on other sites More sharing options...
Schmalle Posted February 4 Share Posted February 4 I don't think you're doing anything wrong. It's just that you're plugging into a HOT tube power amp. You could use the Vitriol preamps to match (A/B) the EVH channels and figure out what their actual levels are. Probably quite low. Quote Link to comment Share on other sites More sharing options...
