Alpine introduces IMPRINT - the world's first technology that thoroughly eliminates in-car
acoustic problems that normally degrade sound quality.
VISION
vs.
REALITY
All
good
music
starts
as
an
artist's
vision.
After
countless
hours
of
rehearsing,
recording
and
mixing,
that
vision
is
ready
for
us
to
hear
on
discs,
radio
and
other
media.
But
do
we
hear
it
as
the
artist
created
it?
Unfortunately,
the
reality
is
that
we
are
almost
never
able
to
listen
to
it
in
the
exact
way
the
artist
intended.
Especially
when
we
are
listening
in
a
car.
CARS
ARE
TERRIBLE
LISTENING
SPACES
Car
interiors
are
full
of
materials
that
obstruct
and
degrade
sound
quality.
For
example,
windows
amplify
and
reflect
high
frequencies.
Seat
and
dashboard
coverings
change
certain
frequencies.
Carpets
absorb
and
suppress
mid
frequencies.
Graphic
and
parametric
EQs
are
only
partial
remedies
for
these
problems.
In
addition,
the
speakers
are
not
located
at
equal
distances
from
listeners,
creating
an
unbalanced,
uncentred
sound
stage.
Time
correction
can
help
fix
this,
but
only
for
one
listening
position.
INTRODUCING
IMPRINT
These
acoustical
problems
are
so
severe
that
no
correction
system
has
been
able
to
overcome
them.
Until
now.
With
the
introduction
of
IMPRINT,
Alpine
provides
a
hardware/software
combination
that
not
only
solves
these
problems,
it
actually
improves
the
sound
stage,
tonal
balance
and
definition
-
and
does
it
automatically,
in
a
matter
of
minutes!
HOW
IMPRINT
IS
DIFFERENT
IMPRINT
using
MultEQ
is
superior
to
other
equalisation
systems
in
five
ways.
1.
It
is
the
only
system
that
measures
the
entire
listening
area,
capturing
time
domain
information
from
each
listening
location
and
applying
a
proprietary
method
for
processing
it
to
represent
all
seat
locations.
This
gives
the
people
in
each
seat
the
optimal
listening
experience.
2.
It
corrects
both
time
and
frequency
problems,
for
an
improved
soundstage
and
smoother,
more
natural
sound.
3.
It
uses
dynamic
frequency
allocation
to
apply
hundreds
of
points
of
correction
to
those
areas
where
the
sound
problems
are
greatest.
4.
It
determines
optimised
blending
points
for
low
frequency
crossovers.
5.
It
provides,
in
minutes,
vehicle
sound
tuning
that
generally
takes
skilled
professionals
days
to
accomplish.
