Peter I have a question...

[Anonymous]

I want to run a Power amp through the VH4 in a W/D/W setup that looks like this...

VH4 and 8 ohm 4x12 for Dry
VHT 2150 power amp and a pair of 1x12's for the wet cabs
stereo effects processor

How do I achieve the connection between the VH4 and power amp without frying anything on the VH4 or power amp?

i guess parallel send to something like the lehle little dual (http://lehle.com/frameset.php?country=de&lang=en) to each fx to stereo vht to stereo cabs for the wet part. dry part should still got through vh4 poweramp and cab.

if you want the diezel poweramp interaction you would follow the king's road.

he wants w/d/w, not w/w

a proper ground loop elimination (50/60Hz hum) would be to use something like an ebtech hum eliminator (http://www.ebtechaudio.com/hedes.html). possible ground loops can occur between vh4 and fx processor, and fx and vht. if you'd use the lehle (there's already a hum eliminator built in) you'd only have to look at the fx-vht-connection. but i'd try first wthout an ebtech and see what happens.

Simple...you would run the processor as a stereo splitter.

Run from the VH4 send to the mono input on the processor, then return the left output on the processor to the return on the VH4. You would then run the right output on the processor to the input of the VHT.

A side note...the VHT 2150 does not have a ground lift switch so you MIGHT need to take the patch cable that you run from the processor to the VHT and disconnect the shield at one end of the cable if you happen to experience ground loop issues. DO NOT BREAK THE AC MAINS GROUND PRONG OFF OF THE POWER CABLE TO FIX THIS!!! Simply take the patch cable running from the processor to the VHT and disconnect the shield from one end of the cable and this should remedy your ground loop. This is ONLY required IF and ONLY IF you happen to experience ground loop issues.

Hope this helps.

Thanks Peter Diezel
