frequency frequency
• HPF (high pass filter): Cuts the lower frequencies and allows the
higher frequencies to pass.
• LPF (low pass filter): Cuts the higher frequencies and allows the
lower frequencies to pass.
• Slope: The level change (in dB) for a frequency change of one octave.
• The higher the slope value, the steeper the slope becomes.
• Adjust the slope to FLAT to bypass the HP or LP filters.
• Do not use a tweeter without the HPF on or set to a low frequency, as
it may cause damage to the speaker due to the low frequency content.
• You cannot adjust the crossover frequency higher than the HPF or
lower than the LPF.
• Adjustment should be made according to the recommended crossover
frequency of the connected speakers. Determine the recommended
crossover frequency of the speakers. Adjusting to a frequency range
outside that recommended may cause damage to the speakers.
For the recommended crossover frequencies of Alpine speakers, refer
to the respective Owner's Manual.
We are not responsible for damage or malfunction of speakers caused
by using the crossover outside the recommended value.

About IMPRINT

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,
uncentered 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 equalization systems in
five ways.
• 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.
• It corrects both time and frequency problems, for an
improved soundstage and smoother, more natural sound.
• It uses dynamic frequency allocation to apply hundreds of
points of correction to those areas where the sound problems
are greatest.
• It determines optimized blending points for low frequency
crossovers.
• It provides, in minutes, vehicle sound tuning that generally
takes skilled professionals days to accomplish.
