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, when the “Full Auto MCACC” operation is performed, the calibration time position is selected automatically in consideration of the room’s characteristics so that the optimum sound field can be achieved. (See page 41 of the receiver’s Operating Instructions.)

When measurements are made with the “Auto MCACC” function, automatic calibration taking the reverberations into consideration is only performed when “ALL”, “Keep SP System” or “EQ Pro & S-Wave” is selected at “Auto MCACC”. (See page 78 of the receiver’s Operating Instructions.)
