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...
