Troubleshooting (Continued)

Cause 1:

The slope of the graph indicates the reverb characteristics. The reverb

characteristics of the room itself cannot be corrected by equalization alone, so

the angle of the graphs’ slope is the same before and after calibration.

Through calibration, the graphs for the different frequencies move horizontally by the amount of the

equalization. For the results of calibration, you can check that the graphs line up at a specific point on

the time axis.

The reverb characteristics themselves (the shape of the graph) do not change unless the listening

environment is improved.

(See pages 18

to 20.)

Cause 2:

For various reasons, the frequency characteristic graphs may not become flat

even when equalization is performed with the “SYMMETRY” or “ALL CH

ADJUST” functions.

With MCACC, calibration is performed automatically to achieve the optimum sound quality, but without

any unreasonable calibration.

Cause:

Despite level adjustments being made, the filters used for analysis may not

display these adjustments in the graphical output.

However, these adjustments are taken this into account by the filters dedicated to overall system

calibration.

Cause 1:

Low frequency calibration with the equalizer is not performed for speakers that

are set to “SMALL”, but the reverb characteristics display shows the pure

characteristics of the sound output from the speakers, so it indicates the

characteristics with no low frequency calibration.

With MCACC, optimum calibration is performed in function of the speakers’ sound reproduction

capacities, so there is no problem for low frequency calibration of speakers that are set to “SMALL”.

EQ response in the graph (following calibration) does not appear flat

Adjustments made with the “Manual MCACC” setup do not change the graph

Lower frequencies do not seem to have been calibrated for SMALL speakers
