H9 Line Level with EBtech Line Level Shifter

[shinobi68]

I am running a W/D/W rig. EVH 5150 III with a Palmer PDI03 JB DI Box between the Amp’s Head and Cab. The PD103 takes a Line Level signal from the speaker out, from there I run it into a Voodoo Labs GCX Audio Switcher going into a Lexicon PCM 70 (4db), then next line in the GCX is a Roland SDE3000 (4db), and from there out to a H/H V800 Poweramp.

Currently for fear of damaging the H9 I left it in the front between my Guitar and Amp input (front). However I want to place the H9 into my wet setup…this is not the FX loop (tube buffered)..it is a Line Level signal taken from the speaker wire. FYI the H9 has worked fantastic in my 5150 III 100S FX loop, I just want that cab to be dry now.

I was looking through my gear and I found that I have an EBtech Line Level Shifter. I have seen a lot of questons on this forum about running a line level signal to the H9 (using search) saying not to do it at Line Level because it was made for Instrument Level. I haven’t found any discussion on using a EBTech Line Level Shifter into the H9?

So can I use my Line Level Shifter coming from the DI Box  (+4db) then input to the H9 (-10db), then from the output of the H9 into the Line Level Shifter input (-10db) then output to +4db to my Lexicon?

The GCX can take any level per the manual.

There's no risk of damaging the H9.  The thing to worry about is if the signal going into the H9 is going to clip; that certainly wouldn't be good for your speakers or your ears if everything was turned all the way up.  You might be able to do what you want to do even without the Line Level Shifter, but it should certainly work with the Line Level Shifter reducing the signal.  You might want to try it either way keeping an eye on the input meters in H9 Control in the Pedal settings section.

The Ebtech didn’t work, like I described I came from the Palmer PDI03 JB at 0db (It has a built in attenuator) and into the EBTech with and the power amp would not get enough signal, I turned off each unit in audio switcher (Lex, SDE, H9), when the H9 was on it would not process the signal for then Power Amp to work, with it off it worked fine. I took the Ebtech out and the H9 was worked fine with no clipping, but I didn’t crank the volume too much either. It sounds great so I just got to try it with the volume up, but it gets very loud in my studio with two cabs :-).

It could be that the Line Level from the Palmer at 0db is not enough to clip the H9.
