Note that changing the room (for example, moving
furniture or paintings) will affect the calibration results.
In such cases, you should recalibrate your system.
Using Professional Acoustic Calibration
1 Select ‘Acoustic Cal EQ’ from the Expert setup
menu.
2 Select ‘Professional’.

•
Auto Pro.
– This is the recommended setup when
using the Professional Acoustic Calibration. If you
feel confident with a setup that’s more involved, you
can use an advanced setup below. With this setup,
the receiver automatically sets an early time period
(20–40 ms or 60–80 ms) for reverb measurement,
giving you a system calibration based on the direct
sound coming from the speakers. The frequency
balance for each channel is then adjusted to
minimize the effect of the room characteristics on the
overall sound.
•
Reverb Measurement
– Use this to measure the
reverb characteristics of your room for each channel
in select frequency ranges. Since this measurement
is also made in
Auto Pro
(above), there is no need to
do this again if you were satisfied with the results.
•
Reverb View
– You can check the reverb
measurements made for specified frequency ranges
in each channel.
•
PC Output
– See
Connecting a PC for Advanced
MCACC output
on page 79 for more on this option.
•
Advanced EQ Setup
– Use this to select the time
period that will be used for frequency adjustment and
calibration, based on the reverb measurement of
your listening area. Note that this advanced setup is
not necessary if you’re satisfied with the results of

characteristics for each channel. Select ‘Exit’ when
you’re done.
