Re: Fwd: Re: RE: Echo Pro - technical ping-pong

 yes... it runs away quite appallingly! :-)

yes... i'm using the xlrs unbalanced into and out of the mixer

i've  had the unit open and, listening with my usual piezo earpiece, i 
can't find the feedback loop - must be in 
the DSP. :-(

i was hoping to find the loop coming through a pair of wires...
