Just ran a test using "Line level only cables" and added the +4 to the SR unit which seems to match my mixer now. Line level sounds better to me, and I was able to keep the SMa LED -10 / -20 at a solid green when sending tone. When testing with a Lav the LED stayed green at -10 / -20 green mostly touching into red when I pushed it on the mixer. The 702T was matching the mixer levels so everything seems to be working out well with these tests. My last question would be, is it normal to see the SMa Led flash into the Red at -20 if I'm pushing it on my mixer? Thanks again for the SR suggestion on +4, that helped out a lot.
