Experience

music

intended

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.
