Im using ps3 for blu-rays, which is my main concern. I have just got into manually adjusting things in mcacc but its really tough. Playing with the standing wave settings seem to help, but I don't fully understand it. Can anyone explain the 3 filters, Freq, Q, and ATT? or give any tricks for mcacc with no subwoofer?
Just kind of guessing here, as I don't have mcacc on my AVR, but they should stand for Frequency, Q or width, and Attenuation.
Frequency is self-evident. It is the number of cycles per second, or hertz, that a tone produces. In the bass range, which is what a subwoofer covers, this would usually be in the 20 through 80 hertz range. But seeing as you don't have a sub, it may run even as high as 150 to 200 hertz on your full range speakers.
Q is the width, or range of frequencies, that are affected by the adjustment. For instance, you may want to adjust a 5 hertz range from 50 to 55 hertz and could set the mcacc control to deal only with those frequencies.
Attenuation, or ATT, means to lower or turn down. Since what we are dealing with here is equalization, the standard methodology calls for attenuation of the frequency or frequencies in question, usually measured in dB or decibels. So you would lower the amplitude, or volume, of the frequencies causing a standing wave. A standing wave is caused by a frequency, or wave length
, fitting into the dimensions of your room exactly, and thus not having the normal decay of amplitude that would typically happen when the frequency does not precisely
fit the room's dimensions. The standing waves that mcacc deals with will be in the bass or low frequency region, as they are by far the most noticeable.
I hope that helps
