i dont understand these graph's....
is it ok?
any "Graph Reader's" care to explain?
Those graphs are similar to the REW charts I did for u sometime back.
They show the frequency response.
The X-axis at the bottom shows the frequencies.
The Y-axis at the left shows the magnitude in dB.
Basically the AVR try to flatten the curve (reduce the peak/valleys) by auto-adjusting it's internal EQ.
I think u remember the wheep-wheep sound you heard when I measured last time.
The AVR should be doing the same, except that the AVR is doing more by figuring out what/where to EQ.
