Before proceeding, connect the correct preamp/processor output to the 1/Mic INPUT of the
Sound Equalizer as shown below.
Transfer the MultEQ XT Filters
Transfer the correction filters you have calculated to the Sound Equalizer by
clicking the Transfer to Sound EQ button. This process only temporarily stores
the filters in the Sound Equalizer so you can listen to them before deciding to
permanently save them. Previously saved filters will not be erased until you click
the Save Permanently to Sound EQ button. The Sound Equalizer can only store
one set of filters at a time.
The Transfer to Sound EQ process may take several minutes depending on how
many channels and how many positions were measured. The download status
bar will indicate the progress of the transfer.
MultEQ XT On/Off demo
After the results are transferred to the Sound Equalizer, the Turn MultEQ On
and Turn MultEQ Off buttons will become available. You can use these buttons
to demo the MultEQ XT filters before deciding to save them permanently to the
Sound Equalizer.
Once the room
measurements are
completed, MultEQ Pro
calculates an equalization
filter for each loudspeaker
channel, including the
subwoofer. These filters
achieve a particular
frequency response within
the entire listening area for
each loudspeaker. This
target frequency response is
determined based on several
acoustical and program
material considerations and
is called a target or
calibration curve.
Contrary to popular belief, a
target curve that is flat from
20 Hz to 20 kHz is not always
the one that will produce the
correct sound. There are
several reasons for this
including the fact that
loudspeakers are much more
directional at high
frequencies than they are at
low frequencies. This means
that the balance of direct and
room sound is very different
at the high and low ends of
the frequency spectrum.
MultEQ XT uses a
proprietary clustering
method to combine room
measurements, allowing for
more precise measurements
over previous room
correction methods. This
clustering approach allows
the MultEQ XT filters to
perform the most
appropriate correction for all
listening positions. MultEQ
XT looks at the room
responses at each
measurement position and
clusters them into groups
based on the similarity of
their patterns and the
severity of their acoustic
problems. This clustering is
not exclusive, each response
can belong to more than one
cluster with a certain
probability. From the
responses in each cluster, a
representative response is
created. From the group of
representative responses, a
“master” response is
created, representing each
“constituent” response in
the best possible way.
