have three receiver's linked together, record out to front aux, two yamaha, vo295's and one yamaha v1070, running seperat high power main speaker's from each, for total stereo 2 channel sound only, question, will adding eq's to each, for tweaking be unsafe? generally one would think the controller receiver's eq, would tweak them all, but it does not do the job to satisfy me, couldn''t i just lower the output on all following eq's from the first one, to escape distortion and clipping?
