Just finished hooking up the 1070 to replace my Yamaha RX-V630. I'm running Rocket speakers (750 front/200 center/300 surrounds) at 88dB/6ohm, 91dB/4ohm and 89dB/6ohm respectively. I'm about 10 feet from the mains & center and 4 feet from the surrounds. I've set the impedence selector on 1070 to 4ohms as instructed. I ran the volume on the 1070 all the way to +10dB and ran the test tones. I get mid to upper 70s of SPL using a Radio Shack digital meter. Is this what I should expect for SPL levels on the test tones at full volume?

Thanks,
Walter
