Troubleshooting (Continued)
Some functions in application operation cannot be used
Cause:
You may not properly use the application software not corresponding to your
receiver.
Check the model number of your receiver and use the application software corresponding to it.
The receiver causes a malfunction when it is connected to the PC with a RS-232C cable
Cause:
When the receiver is connected to your PC with a RS-232C cable, the power of
the receiver may be automatically switched on when you operate the PC.
Unplug the cable when not in use.
EQ response in the graph (following calibration) does not appear flat
Cause 1:
There are cases where the graph does not appear flat (even when selecting ALL
CH ADJUST in the Auto MCACC Setup)
This is due to adjustments made to compensate for room characteristics to achieve optimal sound.
Cause 2:
Areas of the graph may appear identical (before and after) when there is little
or no adjustment needed.
Cause 3:
The graph may appear to have shifted vertically when comparing before and
after measurements.
Adjustments made with the “Manual MCACC” setup do not change the graph
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.
Lower frequencies do not seem to have been calibrated for SMALL speakers
Cause 1:
Low frequencies used in bass management (the subwoofer channel) will not
change for speakers that have been specified as SMALL in the configuration.
Cause 2:
Calibration is performed, but due to your speakers' low frequency limitations,
no measurable sound is output for display.
