Checking Mcacc Data - Pioneer SC-LX81 Operating Instructions Manual

The Advanced MCACC menu
The following options determine how the reverb
characteristics of your listening area are displayed in
Reverb View and Output PC (see Connecting a PC for
Advanced MCACC output on page 69):
• EQ OFF – You will see the reverb characteristics of
your listening area without the equalization
performed by this receiver (before calibration).
• EQ ON – You will see the reverb characteristics of
your listening area with the equalization performed
by this receiver (after calibration).
response may not appear entirely flat due to
adjustments necessary for your listening area.
When the reverb measurement is finished, you can select
Reverb View to see the results on-screen. See
Professional Calibration EQ graphical output on page 113
for troubleshooting information.
4 If you selected 'Reverb View', you can check the
reverb characteristics for each channel. Press RETURN
when you're done.

This appears according to the setting you chose in
Reverb Measurement (step 3 above). Use / to
select the channel and the frequency you want to check.
Use / to go back and forth between the three. Note
that the markers on the vertical axis indicate decibels in
2 dB steps.
5 If 'Advanced EQ Setup' is selected, select the
MCACC memory to be stored, then enter the desired
time setting for calibration, and then select START.
Based on the reverb measurement above, you can
choose the time period that will be used for the final
frequency adjustment and calibration. Even though you
can make this setting without reverb measurement, it is
best to use the measurement results as a reference for
your time setting. For an optimal system calibration
based on the direct sound coming from the speakers, we
recommend using the 30~50ms setting.

to 4 minutes for the calibration to finish.
After the Acoustic Calibration Equalization is set, you are
given the option to check the settings on-screen.
