Setting the Crossover Settings (X-Over)

■

About the Crossover

This unit is equipped with an active crossover. The crossover limits
the frequencies delivered to the outputs. Each channel is controlled
independently. Thus, each speaker pair can be driven by the
frequencies for which they have been optimally designed.

Thecrossover adjuststhe HPF (highpass lter)or LPF(low pass
lter)ofeachband,andalsotheslope(howfastthelterrollsoffthe

highs or lows).
Adjustments should be made according to the reproduction
characteristics of the speakers. Depending on the speakers, a
passive network may not be necessary. If you are unsure about this
point, please consult your authorized Alpine dealer.

Setting the Time Correction

■

About Time Correction

The distance between the listener and the speakers in a car vary
widely due to the complex speaker placement. This difference in
the distances from the speakers to the listener creates a shift in the
sounds image and frequency characteristics. This is caused by the
time delay between the sound reaching the listener’s right versus the
left ear.
To correct this, this unit is able to delay the audio signal to the
speakers closest to the listener. This effectively creates a perception
of increased distance for those speakers. The listener can be placed
at an equal distance between the left and right speakers for optimum
staging. The adjustment will be made for each speaker in 3.4 cm
steps.

Example 1. Listening Position: Front Left Seat

Adjust the time correction level of the front left speaker to a high
value and the rear right to zero or a low value.

The sound is not balanced because the distance between the
listening position and the various speakers is different.
The difference in distance between the front left speaker and the
rear right speaker is 1.75 m (68-7/8").
Here we calculate the time correction value for the front left speaker
in the diagram on the above.

Conditions:
Farthest Speaker – listening position : 2.25 m (88-9/16") Front
left speaker – listening position : 0.5 m (19-11/16") Calculation:
L = 2.25 m – 0.5 m = 1.75 m (68-7/8")
Time correction = 1.75 ÷ 343* × 1,000 = 5.1 (ms)

* Speed of sound: 343 m/s (765 mph) at 20°C

In other words, giving the front left speaker a time correction value of

5.1 ms makes it seem as if its distance from the listener is the same
as the distance to the farthest speaker.
Time correction eliminates the differences in the time required for the
sound to reach the listening position.
The time of the front left speaker is corrected by 5.1 ms so that its
sound reaches the listening position at the same time as the sound
of other speakers.

Example 2. Listening Position: All Seats

Adjust the time correction level of each speaker to almost the same
level.

1. Sit in the listening position (driver’s seat, etc.) and measure

the distance (in meters) between your head and the various
speakers.

2. Calculate the difference between the distance correction

value to the farthest speaker and the other speakers.

L = (distance to farthest speaker) – (distance to other speakers)
These values are the time correction values for the different
speakers. Setting these values to make each sound reach the
listening position at the same time as the sound of other speakers.

see “Setting Camera Guideline”.
You can also turn off the guideline in the Rear camera display
screen.

Indication mark meaning

When the car is put into reverse gear, the monitor switches to the
rear view camera image. Guides appear to help visualise the car’s
width and distance from the rear bumper.

1. Car width extension marks (red, yellow and green in order of
distance)

If properly calibrated, the marks indicate the car’s width. This
helps guide the car’s path when backing up in a straight line.
The marks represent the distance from the rear of the car (from
the rear end of the bumper).

The marks do not move in synchronisation with the steering wheel.
Set the marks to suit the car’s width.

2. Distance guidance marks

The marks represent the distance from the rear of the car (from
the rear end of the bumper).

• The marks do not move in synchronisation with the steering
wheel.

• We recommend that you measure the actual distance to the
marks when parked on a level surface.

• Depending on the condition of the car or road surface, the range
of vision may vary.

•

The camera has a limited range of vision. Objects at extreme

angles to the camera (e.g. under the bumper or at opposite ends

ofthebumper)maynotbeintheitseld-of-vision.

• The rear camera image may have a tint which is different from the

actual surroundings.

•

Depending on the car, the guidance may deviate to the right or

left. This is not a malfunction.

Distance guidance mark

The distance guides represent the ground level distance from the
rear bumper. It is difficult to accurately estimate the distance to
objects above ground level.

In the following example, the distance to A is 0.5 m and the distance
to B is 1 m.

<Screen>

C

B

A (about 0.5 m)

<Positions of A, B and C>

about 1 m

In the screen, according to the distance guidance marks, the truck
seems to be parked about 1 m away (at the position B). In actual
fact, however, if you reversed to position A, you would collide with
the truck.
In the screen, positions A, B and C seem to be located in order of
proximity. However, in actual fact, the position A and C are the
same distance, and B is farther away than positions A and C.

• The car width extension mark represents the distance to the road
surface. The distance to an object on the road is not accurately
represented by the guides.

Error between the screen and the actual road surface

In the following conditions, errors are produced between the screen
guidance and the actual road surface. (The illustrations represent a
case when the camera is installed in the standard position.)

Error Error

Thedistance guidancemarkrepresents thedistance toa atroad

surface. Therefore in the case of an upward slope behind the car,
the distance guides are displayed closer to the rear bumper than the
actual distance. For example, if there is an obstacle on the upward
slope, it may appear farther away than its actual position.
Also, an error may occur between the guidance and the actual path
of the car on the road surface.

When there is a steep downward slope behind the
car (example)

<Screen>

<Situation of the car>

Error Error

In the case of a downward slope behind the car, the distance guides
are displayed farther from the rear bumper than the actual distance.
If there is an obstacle on the downward slope, it seems closer than
its actual position.
Also, an error may occur between the guidance and the actual path
of the car on the road surface.
