Greetings. I just set up my new Pioneer HTP-710 home theater system over the weekend, and I need some input as to whether or not I calibrated everything correctly using the AVIA disc. First of all, I set the receiver's master volume to -20. I then proceeded to adjust each channel's level to whatever it had to be to achieve a sound level of 75db, using AVIA's test tones. Since I calibrated it to 75db, does this mean it won't sound right if I play something at a volume higher than -20? Right now, the only other thing I'm confused about is the subwoofer setup. I've got the LFE attenuation set at 0, and the crossover frequency set at 200Hz. All the speakers are satellites with the exception of the center speaker, which is a Pioneer S-DC1-K. Is this center speaker considered to be large? If so, my receiver will only let me designate it as a small speaker. I did what the AVIA disc told me to do; I set the subwoofer volume knob and the channel level so that the subwoofer signal was at the same level as the high frequency signal. The sub is set at -9db right now. However, I'm worried that I've set it up wrong, because it seems that I'm not getting good lows. I've watched a few DVDs including Gladiator and T2: Ultimate Edition. Of course, I only have an 8" sub, but it seems as if the bass is coming out of the center speaker. I watched "O" last night, and there were a lot of hip-hop songs on the soundtrack. On one particular song, especially, it definitely seemed as if it was all coming out of the center speaker. Am I doing something wrong? Is there some other way to make sure I've got everything calibrated correctly? Any help would be greatly appreciated. Thanks.
