Zone Configuration
The Sound Equalizer performs equalization for up to eight audio channels. These
eight channels can be assigned to zones.
Use the Channel grid to select which channels you are assigning to each zone.
Each column represents a possible zone. For example, if you are calibrating a 7.1
system, then all eight radio buttons in the first column should be selected and each
channel should be assigned from the drop-down menu.
If calibrating two zones (one with a 5.1 system and one with a 2.0 system), then you
should select the first 5 buttons in the first column, and the last two buttons in the
second column. The channels in the second column should be named Left Front
and Right Front.
Finally, if you are calibrating four two-channel stereo systems in different rooms,
select two radio buttons in each of the first four columns.
Multiple Subwoofers
The Sound Equalizer
supports multiple
subwoofers. In fact, all
eight channels can be
used for subwoofer
correction if so desired.
Use of multiple sub-
woofers operating from
various positions in the
room can smooth the bass
response.
There are two ways to
connect multiple
subwoofers.
If the pre/pro has an
advanced bass
management system that
directs bass from different
channels to a separate
subwoofer, then each
subwoofer output should
be connected to a separate
Sound Equalizer channel.
In such systems, the delay
and trims calculated by
MultEQ Pro can be entered
in each individual
subwoofer setting in the
pre/pro.
The most common
configuration for
preamplifier/processors
that provide multiple
(usually two) subwoofer
output connectors is to
have them internally
connected in parallel (y-
cord). In such cases, it is
not possible to enter
separate delays and trims
for each subwoofer. In
this case, connect ONE of
the subwoofer outputs
from the pre/pro to ONE
input channel of the Sound
Equalizer and then attach a
Y-cord to the
corresponding output
channel to feed the signal
to each subwoofer. In this
situation, it is best to place
the subwoofers in
symmetrical locations at
equal distance from the
main listening position
If the subwoofers can not
be placed in symmetric
locations, Audyssey
recommends using a delay
that is the average of the
distances from the
subwoofers to the
principal listening location.
