About the X-Over
Frequency divider (X-Over):
This machine is equipped with an active frequency divider. The frequency divider can limit the frequency that reaches each output.
Each channel can be controlled individually.
Therefore, each pair of speakers can be driven with a n optimized frequency.
The frequency divi der can adjust the HPF (high pass filter) or LPF (low pass fil ter) of each band, and the slope (t he speed of the filter to t he h igh point or low point).
Should be adjusted according to the reproduction characteristics of the speaker.
Depending on the speakers, it may not be necessary to use a passive network. If you are not sure about this, please consult an authorized Alpine dealer.

- HPF (High Pass Filter): intercepts lower frequencies and allows higher frequencies to pass.
- LPF (low pass filter): intercepts higher frequencies and allows lower frequencies to pass.
- Slope: the level change of one-octave frequency change (dB).
- The larger the slope value, the steeper the slope.
- Do not use tweeters that have not set HPF to on or have been set to low frequencies, otherwise the speakers may be damaged due to low frequency content.
- The frequency of the divider cannot be adjusted to be higher than HPF or lower than LPF.
- It should be adjusted according to the recommended crossover frequency of the connected speakers. Please determine the recommended crossover frequency of the speaker. Adjusting beyond the recommended frequency range may damage the speakers.
- We are not responsible for speaker damage or malfunction caused by using a crossover beyond the recommended value.
About Time Correction
The distance between the listener and the speakers in the car can vary greatly due to the complex speaker placement. This difference in distance between the speaker and the listener will cause deviations in the sound image and frequency characteristics. This phenomenon is caused by the time delay for the sound to reach the listener's right and left ears.
To solve this problem, this unit can delay the audio signal sent to the speaker close st to the listener. This can effectively create a feeling of extended distance for th ese speakers. The e distance between the listener and the left and right speakers can be equal to obtain th e best results. Each speaker will be a djusted with 3.4cm as a step difference.
Examples of listening positions are as follows:
Example 1: Front left seat
Adjust the time correction level of the left front speaker to a larger value, and adjust the right rear speaker to zero or a smaller value.

text_image
0.5m 2.25m 5.1mshe distance between the listening position and each speaker is different, so the sound is unbalanced.
The distance difference between the front left speaker and the rear right speaker is 1.75m (68-7/8").
Here we will calculate the time correction value of the left front speaker in the figure above.
condition:
The farthest speaker-listening position: 2.25m (88-9/16")
Left front speaker-listening position: 0.5m (19-11/16")
Calculation: L=2.25m-0.5m=1.75m (68-7/8")
Time correction=1.75÷343*×1000=5.1(ms)
* Speed of sound: 343m/s (765mph) at 20°C In other words, setting the time correction value of the front left speaker to 5.1m s can make the distance between it and the listener seem to be the same as the distance between the listener and the farthest speaker. Time correction can elimin ate the time difference required for the sound to reach the listening position.
The time of the left front speaker is corrected by 5.1ms, so that its sound will reach the listening position at the same time as the
sound of other speakers.
Example 2: All seats
Adjust the time correction level of each speaker to be almost the same.
1 Sit in the listening position (driving position, etc.) and measure the distance (meters) between the head and each speaker.
2 Calculate the difference between the distance correction values of the farthest speaker and other speakers.
L= (distance from the farthest speaker)- (distance from other speakers)
These values are the time correction values of different speakers. By setting these values, each sound can reach the listening position at the same time a s the sound of other s peakers.

About MP3/WMA/AAC/M4A/WAV/FLAC/APE/DSD
Notice
Except for personal use, copyright laws and international conventions prohibit copying audio data (including MP3/WMA/AAC/M4A/WAV/FLAC/APE/DSD data), or distributing, transmitting or copying without the permission of the copyright owner, Regardless of free or
What is MP3?
MP3, whose official name is "MPEG Audio Layer 3", is a compression standard specified by MP EG, a joint executive body under ISO (International Organization for Standardization) and IEC. MP3 file s contain compressed audio data. MP3 encoding can compress audio data at an extremely high ratio, reducing the size of music files to one-tenth of the origin al size. At the same time, t he sound quality remains close to t he level of CD. The MP3 format achieves such a high compression rate by removing sounds that cannot be heard by the human ear or that are masked by other sound s.
What is WMA?
WMA or "Wind ows Media™ Audio" is compressed audio data. WMA is similar to MP3 audio data.
What is AAC?
AAC is the abbreviation of "Advanced Audio Coding", which is a basic audi o compression format adopted by MPEG2 or MPEG4.
What is M4A?
M4A is the file extension of the MPEG-4 audio standard, and M4A files contain compressed audio data.
What is WAV?
WAV is a sound file format developed by Microsoft. It conforms to the RIFF (Resource Interchange File Format) file specification. It is used to save audio information resources on the Wind ows platform and is widely supported by the Wind ows platform and its applications. It also supports a variety of compression algorithms such as MSAD PCM, CCITT A LAW, and supports multiple audio numbers, sampling frequencies and channels. The standard formatted WAV file is the same as the CD format. It also has a sampling frequency of 44.1kHz and a 16-bit quantized number. The quality of sound files is almost the same as that of CD! It is the closest to lossless music format, so the file size is relatively large.
What is FLAC?
FLAC Ch inese can be interpreted as lossless audio compression coding. FLAC is a
well-known set of free audio compression coding, which is characterized by lossless compression. Unlike other lossy compression codes such as MP3 and AAC, it will not destroy any original audio information.
What is APE?
APE is one of the popular lossless compression formats for digital music. Unlike lossy compression formats such as MP3, which irreversibly delete data (insensitive to human hearing) to reduce the size of the source file, lossless compression formats such as APE use a more refined recording method to reduce the volume. The source file is the same, thus ensuring the in integrity of the file.
What is DSD?
The DSD music format is a format of lossless music. Because its encoding method is different from the ordinary encoding method, it is a digital encoding, so it has become a niche and special music format.
How to create
MP3/WMA/AAC/M4A/WAV/FLAC/APE/DSD files Audio data is compressed using g software with
MP3/WMA/AAC/M4A/WAV/FLAC/APE/DSD codec. About creating MP3/W MA/AAC/ For detailed information about /M4A/WAV /FLAC/APE/DSD files, please refer to the software user manual. MP 3/WMA/AAC/M4 A/WAV/FLAC/APE/DSD files that can be pl ayed by this unit have the following file extensions.
MP3 : "mp 3"
WMA : "wma"
AAC : “m4a”
M4A : “m4a”
WAV : "wav"
FLAC : "flac"
APE : “a pe”
Files without extension can not be played. It does not support WMA Lossless, WMA Professional, protected files, or original AAC files (with ".aac" as the extension).
There are many different versions of the AAC format. Confirm t hat th e software used conforms to the above acceptable format.
Even if the extension is valid, it may be a format that cannot be played.
Supports playback of AAC files encoded with iTunes. APE decoding only corresponds to APE v2 tags.

The term
Bit rate
This is the "sound" compression ratio specified for encoding. The higher the bit rate, the better the sound quality, but the larger the file size.
Sampling frequency
This value indicates the number of times t he data is sampled (recorded) per second. For example, a music CD uses a sampling frequency of 44.1kHz, so the sound is sampled (recorded) 44,100 times per second. The high her t he sampling g frequency, the better the sound quality, but the larger the amount of data.
coding
