I was hoping we could discuss some of the amplifier settings on the A370PEQ-2 amp found on the FV15. I know they have been discussed here and there through this 100+pg thread, but I'm needing some additional input, perhaps in more layman terms.Let's first start with the extension frequency...
On the surface, to me this selection seems fairly straightforward. You decide how low/deep you want the sub to dig. But of course, everyone would prefer the lowest frequency possible. So I assume the factor that comes into play with this selection is listening volume. I'm guessing 14Hz at high volumes would greatly increase the risk for damage.Next, damping level...
I'm not real clear on the real world listening effect of damping other than high=clean, low=flabby/bloated. And based on the amp's quickguide documentation, and again, like extension freq., it seems this option has to be selected based on listening volume.And finally (for now), Rumble filter...
I understand this reduces frequencies below 20Hz, and also understand this is beneficial at high listening volumes. (to reduce risk of damage to the sub?) However, and this may be a foolish question, but don't you want subsonic frequencies intact, especially for movies, and to a much lesser extent for music? Next part of my question is how much
are the frequencies reduced? Is it a straight cut off, or some kind of roll-off?
How do these settings interact with Audyssey calibration? Which settings, if any, can be switched back and forth without having to re-calibrate with Audyssey?
It seems like all of these settings are volume dependent...which makes me ask what does Rythmik consider to be low, moderate, and high SPLs? These are very subjective terms that are used in the documentation without any actual relevance to quantitative measures.
Thanks in advance for any help. I've been learning quite a bit from this thread and will be soon picking up the FV15 of F15...but still bouncing back and forth
At least I've made a decision between HSU and Rythmic (for now lol)
