about
Ultra
Tower
phase
and
AN

auto-setup
processes.
AUTO
EQ-

MIC
INPUT
The
Ultra
Tower
side-firing
woofer
array
is
designed
to
provide
a
more
,
accurate
in-room
bass
response
than
a
conventional
front-firing
tower
by
uniformly
loading
the
room,
thereby
reducing
amplitude
variations
caused
by
room
modes.
Since
the
woofers
are
side-firing,
the
bass
at
the
listening
position
is
a
combination
of
direct
and
reflected
sound
waves.
This
may
result
in
a
phase
warning
during
the
A/V
receiver
auto-setup
process.
If
a
phase
warning
is
encountered,
it
does
not
necessarily
mean
there
is
a
problem
with
the
Ultra
Tower
speaker
setup.
While
moving
the
Ultra
Tower
slightly
closer
or
farther
away
from
nearby
wall
boundaries
may
clear
the
phase
warning,
doing
so
is
not
required
to
obtain
optimal
bass
performance,
and
the
phase
warning
may
be
safely
disregarded
if
the
loudspeakers
are
already
located
in
the
preferred
room
location.
As
a
matter
of
good
practice,
any
time
a
phase
warning
is
encountered,
the
polarity
of
the
wiring
at
the
loudspeaker
and
amplifier
should
be
double-
checked
and
corrected
as
needed.
