I couldn't find any stats on the PT-7030 either. But I did find some stats on the Rotel RSP-1572 that shares the same circuitry. The RSP-1572 manual states that the preamp output as:
Preamp Output Level/Output Impedance 1.0V/1k ohms
Only Emotiva/Sherbourn can tell out what the Balanced output levels are, since they are the ones that added them.
Wow, only 1.0V?...most integrated AVR's put that out. That is concerning to me as the amp's I am using have 1.3Vand 1.5V input sensitivities. I was under the impression that most pre/pro's put out quite a bit more...the XMC-1 for example is rated at 11.0V balanced and 5.5V unbalanced.
I'll reach out to Emotiva and see what they have to say.
For those of you that have had issues with HDMI and the PT7030. I purchased a 35ft and 25ft HDMI to replace a previously working 15 ft cable. The 15ft would pass OSD but nothing else. I purchased one of those HDMI splitters off of Amazon that has the USB cable for power. This resolved the issue with the 35ft cable so if you are having issues with HDMI look to boost the signal from the processor.
Hello all, latest issue with my Pt7030, is I am beginning to get popping noises through speakers after about an hour of playing either movies or music from oppo bdp83se. I am using the hdmi in on the Sherbourn. It also comes through when using digital coaxial. Could it be the dac in the sherbourn? Strange thing is, the popping seems to vary from only one speaker at a time, surround, front, center and also sub, never all at once. Called Emotiva, took all info and waiting on response, anybody experience this? Thank you
