i'm using the Avia disc to set/test my levels... I have an Onkyo 797, 6 NHT superzero's and an NHT Subone... i'm using the test that pans around to all 5 channels plus the LFE and plays the low freq tones... It is noticeably quieter (to my ears and the spl meter) when it hits the LFE channel... In the Onkyo setup, however, the sub channel reads the same SPL (~75db) as the other channels... the LFE setup for Dolby Digital and DTS is at 0db so its not losing volume there... all speakers are set to small, so the tone plays from the sub for all channels... any ideas? it doesn't make any sense to me, because its the same tone coming from the same sub, so it should be the same volume unless bass management is messed up, right?
