Setting the radio in the machine for high-quality music playback. The principle of operation of the equalizer. What is a compressor, gate and equalizer

Proper tuning of the car radio

To enjoy music in the car, listening to just installed acoustic systemIt is not enough to simply install all audio components. Need now proper setting Car radio, as well as other devices, such as a processor or an external amplifier, if available.

The process of setting up a head device will be very different from its model and the complexity of the entire audio system in your car. Accordingly, the more components in it, the more difficult it will be done. It should be understood that the possibilities of setting, as well as the number of customizable parameters, will increase in proportion to the price of the device.

For a simpler radio, a limited set of functions and customize there are only a few parameters. Promoted processor headsets have a very broad setup. And yet, it should be said that before the automagnetization is configured, open the instructions for it. No online review will tell you about the functionality of your header more fully than the factory guide will do.

Setting up budget car radio

Let's start with the simplest systems. Suppose you have budget magnetol and two speakers in the front doors, or two more - in the rear, or rear shelf. Of all the options for setting you can only have: the balance adjustment, several equalizer presets, possibly - the gain function low frequencies And some more stern. As in this case, it is produced avtomagnitol setting?

You should adjust the balance of the front and rear speakers with the predominance of frontal. And also adjust the balance between the right and left speakers so that the sound is not "wounded" in one direction. Also select the most pleasant equalizer presets for music you listen. All settings are made exclusively for rumor: you like the sound, or not.

If the magnetic has a built-in high frequency filter (indicated as HPF), it should be turned on. Then "cut off" the low frequencies entering the front speakers, approximately at the level of 100-125 Hz. In this case, the dynamics will not try to reproduce the lowest frequencies, below 80-100 Hz, approximately. This will allow them to play more pure and not "hoarse."

If you still have "ovals" installed in the rear shelf, then using the low frequency filter (it can be designated as LPF or something differently), then the correct adjustment of the car can make them play only low frequencies, almost like. To do this, turn on the filter and set the cut at 50-63 Hz. As a result, your "pancakes" will be played low frequencies, approximately 80 Hz or slightly higher. After such a setup, the sound "scene" will not be shifted back, and it turns out where it should be - in front. The sound after such a setting becomes very pleasant.

By the way, in the same way there can be not only the automagnetization setting, but also a subwoofer, if you connect it to the rear channels of the radio and turn on the low frequency filter. True, to implement this method, it is necessary that LPF is in stock, and also need a subwoofer speaker with high sensitivity so that it can work from the head unit. Of course, the return of low-frame with such a connection will be low, but will allow you to do without external and raise the sound quality to a new level.

Setting up more serious acoustics

If you have a slightly more serious acoustics, such as two-way and subwoofer, and the radio has filters, allowing you to make "cuts" of low and high frequencies, with different steepness attenuation, you need to make similar manipulations, as with the previous system: enable filters and set frequencies. "Cutting". The larger and better front speakers, the lower you can "cut" them, but not lower than 80-100 Hz. Subwoofer usually "cut" at a frequency not higher than 50 Hz.

If there is a crossover in a two-band system, or a resistor that does not miss a high-frequency signal below 4-5 Hz, then high frequencies can only be corrected. If the tweeter connects directly, you need to "cut" it below. Otherwise, he can just burn.

It should be said that by making a "cut" on a certain frequency, you should not expect a speaker to completely play after this frequency. The sound will be, but it will smoothly fluff. How smoothly - depends on the order of the filter. More advanced radio tape recorders and their automagnetic tuning make it possible to choose the order of the filter.

Setting a serious car radio

If there is a processor header, amplifiers in the system or external processor opportunity avtomagnitol setting Very wide. Then you can very accurately configure each strip, making the desired "cut" from above and below, on all the speakers, setting the time delay of the signal, which is important for building the right "scene" by adjusting the tone balance and adjusting the ACH. But the complexity of this setting is maximum.

If you have such a system, then tuning it only on rumor, without special skills, tuning discs and measuring equipment - will be wrong, you can hardly achieve a good result. In this case, it will be better to turn to professionals that do it.

Setting the equalizer.
* 400 Hz
+ The bass line becomes clearer and open, the readability of tools votes is improved. The bass guitar is emphasized.
- The "cardboard box" effect is eliminated in the sound of large drums.
- Plates are moved deep into the sound picture.
* 800 Hz
+ Bass becomes brighter, the perception of low-pass tools is improved. The small drum is focused.
- The "cheap" sound of the guitars disappears: resonances are removed, "cute" brutal pain.
* 1.5 kHz
+ The bass improves clarity and the melodic line is emphasized, "heavy artillery" sounds deliberately expressive.
- Demmeredness ("stupid" character) of acoustic guitars
* 3 kHz
+ Enharged and becomes brighter than bass pinch.
+ On the quiet part of the piano, the attack is improving.
+ Back-vocals sound softer and even more.
+ Masked non-stroke plans.
* 5 kHz
+ The effect of the presence of vocalists is noticeably enhanced with the extension on the front edge of the scene.
+ Increases attack at low-frequency tools (drums).

+ The attack on the piano and acoustic guitar is improved, the sound of an electric guitar becomes bright.
- The second plan of the sound scene is incoming deep into.
- The sound of thin strings of the guitar softens.
* 7 kHz
+ Vocal timbre acquires brightness.
+ Increased attack at low-frequency tools (large drums), metallic notes appear in the sound.
+ At the percussion tools intensifies the attack.
+ Avenate dull voices.
+ Finger sound accentuated on acoustic bass.
+ The sound of synthesizers, electric and acoustic guitars, piano becomes bright, underlined.
- Softened the reproduction of hissing consonants from vocals.
* 10 kHz
+ Vocal timbre becomes brighter.
+ The timbre of acoustic guitar and piano lightened.
+ The sound of the plate becomes more hard.
- soften hissing consonants in voices of vocalists.
* 15 kHz
+ It becomes a brighter timbre of voices of vocalists, the emotional component is distinguished.
+ Plates, string tools and flutes sound brighter.
+ Synthesized sounds acquire the realism of the sound.
Here are several common characteristicswhich can be guided by the equity of various tools:
Frequencies below 100 Hz make the sound more massive and tangible, but can also make it with a bubbling.
Frequencies from 100 to 250 Hz can add completeness sound.
Frequencies about 400 Hz make the sound more rough.
Frequencies from 600 to 800 Hz add the sound of depth and completeness.
Frequencies from 1 to 2 kHz can enhance the audio attack and designate the drum.
Frequencies from 2 to 4 kHz make the tool sound more close, enhance the effect of presence.
Frequencies from 5 to 7 kHz make the sound tool sharp.
Frequency from 10 to 18 kHz add transparency and airiness sound.
Vocals
To create completeness, you can raise the frequency of 150 Hz for 2-3DB.
To raise the intelligibility, add a bit at the frequency of 3 kHz.
To enhance the effect of presence, add a few decibels at a frequency of 5-6 kHz.
If a whistle is present in the vocal, then it is necessary to reduce the strengthening between 7 and 10 kHz.
For brightness and transparency, raise the level above 12kHz.
Electric guitar
For this tool exists great amount Equalization options, each of which is suitable for its specific sound. The main thing is to experiment more. But I still give a few general councils.
To eliminate the dullness of the sound of the electric guitar, you need to weaken the signal at frequencies below 100 Hz.
Increased frequencies from 120 to 250Hz will give sound heat.
The frequency gain from 2.5 to 4 kHz will emphasize the attack, and the gain of 5 kHz will give brightness.
Acoustic guitar
The acoustic guitar sounds better if a little to reduce the frequency of 80Gz and from 800 to 1 kHz.
If you want to get a warm and full tone, you can try to enhance 150 and 250Hz.
Add a few decibel at a frequency from 3 to 5 kHz if you want to emphasize the attack and percussion.
Adding several decibels at a frequency of 5 kHz will give brightness to the tool.
Bas-guitar
It is very important to always remember that the bass guitar and the big drum "barrel" work in close ranges, so you need to try to be clearly audible both tools. You need to configure frequencies to ensure your space for each of them. As a rule, the bass guitar is cut into those frequencies that raise at the barrel. Drums
To reduce the cardboard pride in a large drum, I advise you to cut a bit between 600 and 800Hz.
In order to emphasize the click of the beater hitting the frequency from 2.5 to 5 kHz.
When processing a small drum, the gain from 3 to 5 kHz emphasizes the attack, and the rise at the frequency of 10 kHz makes the sound crispy.
For Tom Tom recommended a slight gain in the strip from 200 to 250Hz.
Cutting the frequencies below 200Hz allows you to get rid of the noise of the other tools with a live record of Heta.
If the plates sound unclear, cut a few decibels in the strip from 1 to 2 kHz.
Impact tools with a high tone, such as a shaker, well sound if a little strengthen high frequencies (above 10 kHz). This will give the sound brightness and softness. You can cut all frequencies below 500Hz to get rid of the sharpness that can sometimes occur when the microphone is too close when recording.
But in general, the equalizer should be in Flat

Correct reproduction of sound on PC is one of the most important conditions for comfort and leisure activities. Configuring sound parameters can cause difficulties in inexperienced users, in addition, problems often occur in the components, and the computer becomes "dumb". In this article, let's talk about how to set up the sound "for yourself" and how to cope with possible problems.

Configured sound in two ways: using specially designed programs or system equipment To work with audio devices. Please note that it will discuss how to adjust the parameters on the built-in sound cards. Since complete with discrete, your own software can be supplied, then its setting will be individual.

Method 1: third-party programs

Programs for setting the sound are widely represented on the network. They are divided into simple "amplifiers" and more complex, with a variety of functions.

Method 2: Standard Tools

Built-in system equipment for configuring audio does not possess phenomenal capabilities, but it is the main tool. Next, we will analyze the functions of this tool.
You can access the settings from "Task panels" or system tray, if the icon you need "hid" there. All functions are caused by the right mouse click.

Playback devices

This list contains all devices (including not connected if there are drivers in the system) that are capable of playing sound. In our case, it "Dynamics" and "Headphones".

Choose "Dynamics" and click "Properties".

Here, on the tab "General", you can change the name of the device and its icon, view information about the controller, find out to which connectors it is connected (directly to motherboard or front panel), as well as disable it (or enable, if disabled).

Note: If you change the settings, do not forget to click "Apply"Otherwise they will not take effect.

Tab "Levels" Contains the overall volume setting slider and function "Balance"which allows you to manually adjust the power of the sound on each column separately.
In chapter "Enhancements" (incorrect location, the tab must be called « Additional features» ) You can enable various effects and configure their parameters if it is provided.

Please note that the inclusion of any of the effects described above may result in a temporary trip drive. In this case, the restart of the device will help (physically disable and enable speakers in the connectors on the motherboard) or the operating system.

On the tab "Additionally" You can configure the beaches and the sampling frequency of the playback signal, as well as the monopoly mode. The latter parameter allows programs to play the sound independently (some may simply do not work without it) without resorting to hardware acceleration or using the system driver.

The sampling frequency must be configured for all devices the same, otherwise some applications (for example,) may refuse to recognize and synchronize them, which is expressed in the absence of sound or the ability to record it.

Now press the button "Tune".

Only the settings contained in the block are available for headphones. "Properties" with some changes in the functions on the tab "Additional features".

Default

Device defaults are configured as follows: on "Device by default" all sound will be output from applications and OS, and "Device default communication device" It will be turned on only during voice calls, for example, in (the first in this case will be temporarily disabled).

Recorders

Go to record devices. It is not difficult to guess what it is "Microphone" And maybe not one. It may also be easy « USB device» if the microphone is in a webcam or connected via USB sound Card.

If you click on the button "Tune", we will see the window with the inscription, which says that "speech recognition is not provided for this language." Unfortunately, today windows Can not work with Russian speech.

P Music to set up music in the car, this occupation is not from the lungs, a lot of nuances, features and difficulties. Each system is unique and must be configured individually.

To understand how important it is and it is difficult to set up a car audio system, I will give your example. My system is far from an ideal and certainly not an example for imitation, however, even on it you can get a pleasant sound.

Composition of the system:

GU (radio) - Pioneer DEH-3200U
Front - Morel Tempo 6
Rear - some Ovals from Schmister (perform the role of free-Air subwoofer)
Amplifier - Blaupunkt GTA 475

In order to configure it correctly, you must also connect correctly! If you connect everything, as it should be, according to the instructions, no longer wondering what is good, keep in mind that it only concerns this case! The problem is as follows - if the front and rear speakers are connected correctly, plus to the plus, minus to minus, they play in the same phase and this leads to bass dating, especially this is noticeable in the Midbas cut area. Therefore, I had to flip the phase on the rear speakers, I connected plus to minus, minus to the plus, on both columns.

And now about why the speakers perform the role of free-car subwoofer, and do not play as the usual column, reproducing the entire sound range - the fact is that if the speakers play the whole sound strip, they drag the sound on one side and not about which sound scene And there can be no speech. Simply put, all the sound is heard or with the right door or left. Therefore, it was decided to cut the rear speakers LPF the amplifier filter, as the subwoofers cut, configuring them under the front Midbas.

Setup audio system - Initially I set up the system exclusively for rumor, with the help of sinuses ( sound files One frequency: 25,26,27 ...... 100Hz) Solved from how Hz playing front Midbas playing, they played confidently from 60Hz and therefore, on the HPF filter, everything was cut into the HPF regulator in other words. Docked the rear speakers with the front, exhibiting the LPF filter, too, at 60Hz, it did not lead to the desired result, I had to gradually twisted to 80Hz. Adjusted the equalizer of the radio for itself, but still something lacked. For a long time, he constantly twisted the settings so, then the Syak. In general, I have already humbled with it and thought it would not be better that this is the maximum that you can squeeze out this system.

But at one point, I became the owner of USB RTA Meter - and, which I needed for more accurate calculations of subwoofer buildings, but not about this now. This device allows you to see how music sounds! Started acquaintance with the device, its capabilities and software, and for one, I checked how well the music is configured, making the first measure achk (amplitude - Frequency characteristics) Audio system, I was amazed - how terrible uneven schedule was. Now I immediately became clear why I was missing something. I had a big hump at 35Hz-ah, then I walked in the area of \u200b\u200b60 Hz, to 80 climb and again failure, etc., and this I will tell you a very responsible place of sound range, failures and lifts in the middle and on top, little Who will feel, but unevenness in the bass range, does not feel anything with the ears of disturbed bear. In other words, half the bass I did not hear, because on the background of peaks, the frequency range in failures is practically not heard.

Chart Ahh Made during the setup, the first schedule was much worse.

Why is everything so bad? The cuts like are set up correctly, dusting the rear to the front is also sort of like a good, but the car itself is a car. Analyzing the Chart of Ahh, I realized that I had a basic problem with the resonance of doors, the dynamics were cut into 60Hz, and the doors still sang already with 35 Hz, giving a large hump in the area of \u200b\u200b40 Hz. It's hard to fight with resonance, and I snorted - raised Midbas above 60Hz, thereby smashed the door resonance with a really reproducible range and reducing the non-uniformity of the graph above the range, and then slept the rear and adjusted the parameters of the equalizer on the radio.

The final setting was carried out with an accurate fit of the cuts of both filters (front and rear) relative to each other and the adjustment of the heine, making the removal of the frequency response after each change. For me, the system configuration was so logical that I've definitely not exactly when it didn't configure it, the accuracy, chase change, leads to an unpredictable change in the schedule!

The penultimate Chart of Ahh, on the latter was a practical ideal decline in the bass range, in the flesh to 150Hz. Unfortunately, I did not have time to make a screen, a laptop sat down.

The setting took much more time than the rumor setting, but the result exceeded all my expectations. Feels like, as if, the system upgraded the system with better - expensive components and sabs (no, the pressure of the crazy, of course not, but play the speakers are very nice and very similar to the system with a subwoofer in Zya). In the evening, a friend came and sat down to evaluate the result, I hardly pulled him from drinking beer from the car.

I could customize the system even better, experimenting with the design and arrangement of speakers, but I have other plans, the most important thing I understood - accuracy in auto sound is very important and without measuring equipment to achieve success is practically impossible.

USB RTA Meter - an indispensable device! They can only be measured as a system in general and components separately, it will immediately show weak points and will allow them to eliminate them, unless you have a physical and technical opportunity. Even without having experience in setting up, with the device, you can configure the system at best.

And I want to give one small advice to you - install the amplifiers to the place where they will be less susceptible to vibrations, not what shelves and subwoofers. I got configured every other day. And to customize I spent half a day!

At the beginning of our article, it makes sense to immediately notify that the following methods for setting the radio tape recorder is designed to the user initial levelAnd there is nothing superpower in it. We also note that the quality of the sound sound is usually only 33% dependent on the composition and quality of the components of the equipment. It depends on the correct installation of the equipment, and the remaining 33% is from the literacy of the audio setting.

In this article we will analyze how to set up a pioneer radio. Adjustment recommendations are considered on the example of the Pioneer Deh-1900ub model from the 2017 lineup. They can also be used to adjust other modern Avtomagnitol Pioneer because everyone has the same menu. Exception represent processor devices whose setting is somewhat more complicated.

Equalizer

The equalizer allows you to make the sound more smooth - raise or lower bass, medium and high frequencies. This is pretty thin tuning audio systems. Not the entire range of sound is regulated immediately, as in other menu items, and specific frequency bands. W. different models There is a different amount of them, depending on the class of equipment. In Pioneer radio, there are five of them: 80 Hz, 250 Hz, 800 Hz, 2.5 kHz 8 kHz.

The equalizer is in the "Audio" section of the settings menu, the EQ item. In it, you can choose one of the pre-installed standard settings. For those whom these options are not satisfied, there are two sets of user settings (Custom). You can switch between them from the menu and the EQ button next to the joystick.

To make changes in frequency parameters in Customizing, you need to select it with a wheel and click on the joystick. Then turn the wheel to choose one of the equalizer frequency bands. Press the joystick again and set the position from -6 (frequency weakening) to +6 (strengthening). Acting in this way you can make some frequencies louder, others - quieter.

The universal recipe for setting the equalizer on the radio does not exist. It is produced by hearing depending on the preferences of the consumer. Moreover, different variants Adjustments are selected under a certain genre of music.

Only approximate recommendations can be given:

if heavy music is played, it is necessary to strengthen the bass - 80 Hz (but not too, + 2- + 3 sufficiently). The same tools are sounded in the region - 250 Hz;
for music with vocals, approximately 250-800 + Hz are needed (men's voices below, female - higher);
e-music will need high frequencies - 2.5-5 kHz.

Setting the equalizer is a very important stage. With this tool, you can create a multiple of the sound quality. Even if acoustics are not very expensive and high-quality.

High frequency filter

Next, we find the HPF (High-PassFilter) item. This is a high frequency filter that cuts the frequency of the sound supplied on the speakers below their boundary passport value. This is due to the fact that, standard speakers (13-16 cm) due to a small diameter of the diaphragm and low power, it is very difficult to play low frequencies. As a result, the sound is reproduced with distortions even on a small volume. If you trim low frequencies, you can get a clean sound in a larger volume range.

Then you can exit the return button and check the result. Do it better on volume 30.

If the sound quality does not suit, or if you are in nature, and I want to arrange a loud disco, you can raise the lower border from 80-120 Hz and more. The same level of boundary cuts is recommended to apply if there is a subwoofer. These activities will allow multiple to increase the purity and volume of the playback sound.

Also here is the adjustment of the steepness of the attenuation of frequencies. On Pioneer it happens in two positions - it is 12 and 24 dB per octave. We advise you to set this indicator by 24 dB.

Low Frequency Filter (Subwoofer)

After we have dealt with speakers, make the tape recorder under the subwoofer. For this we need a low frequency filter. With it, we docile the frequency of columns and subwoofer.

The situation is as follows. When we removed the bass acoustics (installed HPF on 80+), we got loud and qualitative sound. The next stage we must "dock" to our subwoofer columns. To do this, go to the menu, select the audio item, we find the subwoofer control section in it.

There are three meanings here:

The first digit is the subwoofer cutoff frequency. Here is still the same as with an equalizer. Specific installation values \u200b\u200bsimply do not exist, and the range in which you can play for, ranges from 63 to 100 Hz.
The next digit is the volume of our subwoofer. We think here everything is simple, you can make a subwoofer louder or quieter relative to acoustics, scale from -6 to +6.
The following digit is a circular frequency attenuation. It also, as in HPF can be either 12 or 24. There is also a small tip: if you install a high cut, then make a steepness of the decline by 24, if it is lower, then you can set 12 or 24.

The sound quality depends not only on the configuration of your audio system, but because you are installed on. If you want to replace them, we advise you to get acquainted with the article ""

Radio setting

Even the favorite music recorded on the USB flash drive or USB driveOver time, it may be bored. Therefore, many motorists love to listen to the radio during the trip. Properly configure the radio for the Pioneer radio tape recorder is easy and can be satisfied with several movements - you just need to select the range, find and save the stations.

Configure radio can be three ways:

Automatic stations search. To do this, find the BSM item in the Settings menu and start the search. AvtoGNITOL will find the station with the highest frequency in the radio view and stops - it can be saved by pressing the button with the number 1-6. Next, the search for stations will continue towards the frequency reduction. If nothing is found, in the hidden menu of the settings you can change the search step from 100 kHz at 50 kHz.
Semi-automatic search. Being in radio mode, you need to hold the "right" button. Range scanning will start, and the search will occur, the same as in automatic mode.
Manual setting. Short clicks of the "Right" button in radio mode can be switched to a certain frequency. The station is then stored in memory.

When all 6 places for saved stations are filled, you can switch to the next memory section. All of them 3. Thus, you can save up to 18 radio stations.

Turning off the Demo mode

Immediately after buying and connecting the radio, you should figure out how to disable the demo mode designed to display the device in the store. You can use the radio in this mode, but it is inconvenient, since when it is turned off, the backlight does not go out, and the display runs on the inscription with different information.

Disabling the demo mode is carried out very simply:

We go into the hidden menu, turning off the radio and climbing the SRC button.
In the Turning Wheel menu, we reach Demo.
We switch demo mode from the ON position in OFF.
We leave from the BAND button menu.

Also in a hidden menu, you can configure the date and time when entering the System section. Here the time display (12/24-hour mode) switches. Then open the "Clock Setup" item, and set the wheel turning time. The System also has a language setting (English / Russian).

If you are reset settings when the ignition is turned off, the article "" is the answer to this question 🙂

Thus, after the purchase of a modern Pioneer model, the tape recorder setting can be done independently. Correctly adjusting the parameters of the audio, you can achieve quite high-quality sound Even a simple audio system and get a good sound picture at minimal cost.
