How to Interpret the Graphs (Continued)
Case 3: Specific frequency shows unusual reverb characteristics
There is probably something in the room that affects the reproduction of that frequency. If possible, try to
find an arrangement that reduces the effect.
Case 4: A specific channel is slow to start
This can happen when a speaker is unstable. If possible, we recommend that you try to stabilize the
speaker stand, to bring the characteristics of that channel into line with the other channels.
Note
In all of these cases, you can use the "ALL", "ALL(Keep SP Setting)" or "Aco Cal EQ Pro." setting from the
"Auto MCACC" option menu to automatically achieve the optimal calibration for the characteristics of your
listening area.(See page 34 to 35 of the receiver's Operating Instructions.)
