Hello, I am looking for some help with settings on my new surround. I have a very small living room/house 1,500sqft. Long Living room. Wood floors. Here is what I have. Onkyo 7.1 TX-SR703 Receiver Polk RTi70 Main speakers Polk CS350-LS Center Speaker Klipsch rear speakers, Not sure of model, just know they are THX speakers Velondyne VA-1512 some of the question I have are , one, with the sub. Where to set the Phase knob too? Low-pass crossover? should i set it too around 100hz? there is a lowpass crossover switch, set to normal or bypass? also there is a Highpass switch i can go from 80hz or 100hz Next, when I go to to speaker setup/config, it allows me to set hz of each speaker, mains, sub, rear, and center, 80hz (THX certified) is what I have them all on now. sub, I can set it to LFE or Direct B And last ,( for now) LOL, when I use the set-up MIC to set speakers, when done, it sets all my speaker levels very low, all of the - dB, then I have to go back in and move each individual one back up, or else I have to turn volume knob up very high. ( well about 70%) Thanks for all the set up help guys. Bear with me!!
