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 aproprietary 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.
