About th e X-Over Frequency divider (X-Over): This machine i s equipp ed with an active frequency divider. The frequency divider can limit the frequenc y that reaches each output. Each chan nel can be controlled indiv idually. 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 th e speakers, it may not be necessary to use a passive network. If you are not sure about this, please consult an authorized Alpine dealer. Active 2-way: Cut-off frequency (The level difference is 1/3 octave band) Slope HPF LPF HPF LPF Subwoofer speaker

Active 3-way: Cut-off frequency (The level difference is 1/3 octave band) Slope HPF LPF HPF LPF Woofer speaker

6/12/18/24 /30/36/42/ 48dB/oc t. ----23 EN HPF (High Pass Filter): intercepts lower frequencies and allows hi gher 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 n ot use tweeters that hav e not set HPF to on or ha ve been set to low frequencies, otherwise th e speakers may be dam aged due to low frequency content. The frequency of the divider cannot be adjusted to be high er than HPF or lower th an LPF. It sh ould be adjusted according to th e recommended crossover frequency of the connected speakers. Please determine the recommended crossover frequency of t he speaker. Adjusting beyond the recommended frequenc y range may damage the speakers. We are not responsib le for speaker dam age or malfunction caused by using a crossover beyond the recommended value. About Ti me Correction The distance between th e listener and the speakers in the car ca n vary greatly du e to the complex speaker placement. This difference in distance between th e speaker and t he listener will cause deviations in the sound image and frequency characteristics. This phenomen on is caused by the ti me delay for the sound to reach the listener's right an d 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. Th 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 t he right rear speaker to zero or a smaller value. he distance between the listening position an d each speaker is different, so th e s ound is unbalanced. The distance difference bet ween the front left speaker an d 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℃ In other words, setting th e time correction value of the front left speaker to 5.1m s can make the distance between it a nd th e listener seem to be the same as the distance between the listener and the farthest speaker. Time correction can elimin ate th e t ime difference required for the sound to reach the listening position. The ti me of t he left front speaker is corrected by 5.1ms, s o that its sound will reach the listening position at the same time as the24 EN sound of other speakers. Example 2: All seats Adjust the time correction level of each speaker to be almost th e same . 1 Sit in the listening position (driv ing position, etc.) and measure th e distance (meters) between th e hea d 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 t ime a s th e soun d of other s peakers. Time correction value list

Information About the Formats Supported by this Nnit For a list of playback formats supported by USB, please refer to "About USB playback formats" (page 24). About MP3/WMA/AAC/M4A/WAV/FLAC/APE/DSD Notice Except for perso nal use, copyright laws and international convention s prohibit copying audio data (including MP3/WMA/AAC/M4A/WAV/FLAC/APE/DSD data), or distribut ing, transmitting or copying without the permission of the copyright owner , Regardless of free or charge.26 EN What is MP3? MP3, whose official n ame 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 aud io 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 sa me 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 aud io 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 exten sion of the MPEG-4 audio standard, and M4A files contain compressed aud io data. What is WAV? WAV is a sound file format devel oped by Microsoft. It conforms to the RIFF (Resource Interchange File Format) file specification. It is used to save audio information resources on th e Wind ows platform an d is widely supported by th e Wind ows plat form and its applications. It also support s a variety of compression a lgorithms such a s MSAD PCM, CCITT A LAW, and suppor ts multiple audio numbers, sampling frequencies and channels. The standard formatted WAV file is t he sa me a s t he 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 th e 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 aud io 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 t he pop ular lossless compression formats for digital music. Unlike lossy compression formats such a s MP3, whi ch irreversibly delete data (insensitive to human hearing) to reduce the size of the source file, lossless compression formats s uch as APE use a more refined recording method to reduce the volume. Th e source fil e is th e same , thus ensuring the in tegrity 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, i t is a digital encoding, so it has become a niche and special musi c format.
