Yamaha RX-V673 7.2-Channel Network AV Receiver

Yamaha RX-V673 7.2-Channel Network AV Receiver
  • I just spent a few hours installing this receiver. The problem is that the zone 2 output (using RCA jacks) into my NUVO Concerto whole house audio has VERY low volume. This is not a problem with any other sources (iPhone direct through headphone jack, DVD player direct, Hughes HR 20 DVR, etc...). I understand that the volume level is FIXED when output to zone 2 through RCA jacks. I know that I can control using the NUVO amp, but the signal is so light that even at max volume the sound output is very low and of course distorted at that high level. I hope I misunderstand something because, if this is a design flaw, it is a showstopper for me. Will update with what I hear from Yamaha.Update 6/23: Yamaha service has told me that this zone output, as spec'd at 200mV / 1.2k ohms is not compatible with my zone 2. Interestingly, they have upped the output voltage to 1V on the Aventege RX-A1020. A 5x increase. So if you need to drive an input to another integrated amp, may want to consider this…
