Route audio to Output 1&2 *without speaker blocks* but send speaker block output to 3&4?

[luvtorekord]

Hi all. Fairly new Helix Floor user here with a question:

I am running all audio from my Helix into a stereo poweramp into a 4x12 cabinet so I don't "need" any speaker blocks on my presets.

 

However, for gigs where I need to go through the PA for additional volume (instead of micing the cabinet) can I setup the Helix to route all audio blocks in stereo (except speaker cab blocks) into my poweramp running my 4x12 cabinet but also add speaker blocks to my presets and send all blocks including speaker block outputs through separate outputs of the Helix into the PA mixing board? (Diagram attached for clarification)

 

This way the audio going into my 4x12 cabinet would not require speaker blocks but the audio routing into the board WOULD need speaker blocks to emulate speakers.
Thank you in advance for your time and keep jammin.

So

I use 2 sends before the cab block to goto my power amp . 

The output block is set to xlr for the PA.

Works fine

You can add a return block right before your Cab block/IR.  Connect that Return to the physical amp.  If you want to have delays in both of your paths, then it becomes tricky... You'd need to duplicate your path and have 2 mixes: one without the cab/IR, the other one with... 

 

My advice is to just run the Helix into the effects loop of your amp with cab/IR sims intact.  Most people have been doing this and there are no issues.  Fix your sound discrepancies with Global EQ.
