Kako uporabljati omrežni način v avtoradiu?
V omrežnem načinu avtoradio oddaja tri vrste izhodov – visokofrekvenčni izhod, srednjefrekvenčni ali pasovni izhod in nizkofrekvenčni izhod.
Toda kaj je omrežni način in kako ga pravilno nastaviti? Ugotovimo.
Omrežni način se uporablja za nastavitev visokotoncev, srednjetoncev in nizkotonca iz ločenih izhodnih kanalov v avtoradio. Poleg tega morate tudi spremeniti način delovanja v omrežni način na avtoradiu.
V tem članku se bom poglobil v to, kako uporabljati omrežni način na vašem avtoradiu in kakšne so zahteve za razporeditev zvočnikov v tem načinu.
Kaj je omrežni način v avtoradiu?
Vsak avtoradio ima vgrajene napredne zvočne funkcije. Avtoradio je mogoče nastaviti v standardnem načinu ali v trismernem omrežnem načinu.
V omrežnem načinu nastavite zvočne izhode kot visoke, srednje in nizke, ker je to trismerni izhod:
- visokofrekvenčni izhod je za visokotonce
- srednjefrekvenčni izhod za srednjetonske zvočnike
- in nizkofrekvenčni izhod za globokotonce
Torej, v omrežnem načinu lahko te tri priključite na avdio sistem vašega avtomobila.
Ne pozabite, da boste ob ponastavitvi avtoradia izgubili vse podatke, shranjene v stereo napravi. Vaše barve torej ni več, prednastavitev ni več, vaš telefon ali povezane naprave so bile izbrisane.
Če želite preveriti, ali je vaš avtoradio v standardnem ali omrežnem načinu, naložite disk in pojdite na »nastavitve zvoka .”
Pomaknite se navzdol in pojdite na »raven zvočnikov .” Videli boste dva visokotonca, dva srednjetonca in en nizkotonec, odvisno od značilnosti vašega avtoradia. To pomeni, da je vaš avtoradio v omrežnem načinu.
Kakšna je razlika med standardnim in omrežnim načinom?
Ko prvič vklopite avtoradio ali ponastavite na tovarniške nastavitve, vas bo najprej pozval, da izberete jezik in nato izberete med standardnim in omrežnim načinom.
Omrežni način je 3-smerni izhodni sistem, medtem ko ima v standardnem načinu avtoradio 2-smerni avdio izhod, vendar to ni edina razlika.
Med standardnim in omrežnim načinom sta dve glavni razliki –
- Razlika v izhodih RCA
- Uporaba prehodov
Poglejmo jih enega za drugim.
Razlika v izhodih RCA
Če pogledamo zadnjo stran stereo naprave, imajo nekateri tri sklope izhodov RCA za delovanje zunanjih ojačevalnikov.
Zgornji par izhodov RCA
V standardnem načinu so zgornji nabor izhodov RCA sprednji avdio izhodi. To so zvočni izhodi celotnega obsega iz vseh virov, vključno z Bluetoothom.
V standardnem načinu se telefonski klici Bluetooth slišijo prek sprednjih RCA izhodov ali sprednjih zvočnikov.
V omrežnem načinu zgornji nabor izhodov RCA postane zvočni izhod visokega dosega, ki se uporablja za povezavo visokotoncev. Zato, ko izberete način omrežja, ne boste prejemali telefonskih klicev prek sprednjih kanalov.
Srednji par izhodov RCA
V standardnem načinu je srednji sklop RCA za zadnje zvočnike. V tem načinu so to zvočni izhodi polnega obsega in iz zvočnikov, povezanih s temi izhodi, ni slišati telefonskih klicev.
V omrežnem načinu postane srednji RCA zvočni izhod srednjega obsega, signali Bluetooth za telefonske klice pa se prav tako pošiljajo prek teh povezav RCA. Poleg tega lahko za ta izhod v omrežnem načinu uporabite visokoprepustni in nizkoprepustni filter.
Spodnji par izhodov RCA
Tretji par izhodov RCA se uporablja za nizkotonec v standardnem in omrežnem načinu.
Uporaba prehodov
- V standardnem načinu sistem uporablja pasivni prehod.
- V omrežnem načinu sistem uporablja interne avtoradijske križance. Zato omogoča omrežni način večjo prilagodljivost pri nastavljanju točk prehodov kot pasivni prehodi.
Ali na svojem radiu izberem omrežni ali standardni način?
Omrežni način in standardni način sta dva bistveno različna načina ožičenja, nastavitve in namestitve avtoradio sistema.
Izbira uporabe vašega stereo sistema v standardnem ali omrežnem načinu je odvisna od vrste avtomobilskega avdio sistema, ki ga želite.
Na primer, če želite zvočno ureditev s standardnimi koaksialnimi zvočniki širokega razpona, priključenimi spredaj, na zadnjih vratih in nizkotoncem zadaj, morate izbrati standardni način.
V omrežnem načinu stereo oddaja tri izhode:
- visoko
- sredi
- nizka frekvenca
Torej, če boste nastavili nizkotonec, srednjetonce in visokotonce, potem izberite omrežni način na avtoradiou.
Naslednje vprašanje, ki vam pogosto pride na misel, je:
V zadnjih vratih imam koaksialni zvočnik, v prednjih vratih visokotonec in srednjetonec, v prtljažniku pa nizkotonec. Should I use network mode?
The answer is NO because the arrangement is for the front, rear, and sub-channels, even though you have different audio drivers.
The easiest way to think about it is if you have a rear speaker, then you are not doing network mode.
When making adjustments to the systems in either network mode or standard mode, keep in mind that the speaker level outputs always give out the same frequency that you can compare to the RCA outputs.
How to Set up Network Mode In-Car Radio
Setting up the network mode is not complicated, and I will use the Pioneer AVH 2400NEX for the example below so that you can follow it directly.
However, most Pioneer radios have the same settings, so there should be no differences in the process.
For New Car Radio
If you have a new car stereo, follow these steps to set up network mode:
- If your car radio is brand new and it has powered up for the first time, then the first thing you have to do is select the “language.”
- After choosing a language, the next question you see is the fundamental setup question regarding the audio system. Again, you will see two modes – standard mode and network mode.
- Select the “network mode,” press OK, and now your stereo is in network mode.
For Old Car Radio
Now, what if your car radio is not brand new or already in standard mode?
Most people are already using their car radio in standard mode. To put the car radio into network mode, follow these steps.
Restore Car Radio
- Go into the “settings” of your car radio. Scroll up and hit “Restore Settings,” then hit “restore.” Wait patiently, and it will restore the settings of your car stereo like that of a new one. Each stereo has a slightly different procedure to restore settings, so you should read the device manual to find out how to restore factory settings.
- Now select the language of your car radio, and the next thing you have to choose is “network mode.”
- Congratulations, your stereo is now in 3-way network mode.
How to Connect Speakers to a Car Radio in Network Mode?
After choosing the network in your radio, the next thing is to hook up the tweeters, subwoofer, and midrange speakers to the car radio.
When setting up this system, it is critical to understand the frequency response of the tweeter and midrange driver package.
- First, you have to connect the tweeters. If you are using an amplifier, the steps remain the same. The front RCA – white and grey have to be connected to tweeters.
- The next are the midrange speakers, which you must connect through purple and green rear RCA outputs. This is important because of the crossovers, the volumes, and the time connections. So, you have to get this portion right.
- There is no deck power for the subwoofer. The RCA connections for the subwoofer are the only ones that do not change between the standard and the network mode.
The above steps explain how the 3-way network system is connected. The whole idea of doing network mode is to throw passive crossover away from the car sound system because passive crossover is a power-robbing device.
There are various advantages of using car radio in network mode rather than passive crossovers.
In network mode, you have more control over the frequency settings, and you can pick up crossover points, for example, at 6, 12, 18, 24 dB.
Most tweeters also have an attenuation circuit that allows you to attenuate like +3dB, 0, or -3dB in the standard mode, but when your radio works in the network mode, the volume control allows you to attenuate (gain it up or gain it down) the tweeter any way you want.
How to Adjust Crossover Points in Network Mode?
The confusion many people will face is when it comes to the crossovers. It isn’t obvious for beginners and may need professional help, so let’s go through the basics.
As a general rule, the frequencies should be set at the crossover as follow:
- For tweeters, tune the crossover points to the high frequency range
- for midrange, adjust crossover points to mid-frequency output
- tune the subwoofer to low frequencies
Here are the steps to set crossover points in network mode:
- Open the speaker settings in the stereo, go to the “balance ,” and you will see a screen that shows a balance between left and right speakers.
- Now go to “crossovers ,” and you will have features like high pass filter, mid low pass, mid high pass, and subwoofer. There are also numbers appearing on the screen that show crossover points.
- For any high pass filter, you can set the crossover at 1.25K, 1.6K, 2K, 2.5K, 3.15K, 4K, 5K, 6.3K, 8K, 10K, and 12.5K, but these points may be slightly different in different stereos.
- The crossover is critical as it protects your speakers from blowing, so you have to get it right. What I recommend doing is to connect each speaker individually and listen to them one by one. While adjusting crossover points, you want to make sure that you are not getting any undesirable sound or distortion from them.
- After this, play the speakers in pairs. For example, play tweeter and midrange together and see how they sound or play tweeter and subwoofer together, adjust the crossovers and see if they are producing any distortion or not.
In the following steps, I will show you exact crossover points for all drivers.
For this, you may need an RTA (real-time analyzer), which is a PPA 3 device (personal audio assistance). The screen on RTA shows you how your sound looks and what it does to the speakers. If you do not have the RTA, much more affordable options is to use the AudioControl SA-4100i Omni-directional Audio Test and Measurement Microphone to measure not only frequencies for each speakers, buy also its polarity that is critical for the best sound quality.
The best is to use the pink noise tracks to analyze the sounds. Pink noise puts out a flat-level sound ranging from 20Hz to 20,000Hz (human hearing range), and when adjusting the crossovers, you can see the exact sound level on each frequency on the RTA screen.
Now you have arranged your stereo and RTA screen, follow these steps to set up crossover points in network mode.
- Connect the RTA screen to the high-frequency output of a car radio.
- Go to “crossovers ,” and for a high pass filter. An excellent place to start is 8K, giving you a 6dB slope. This means that the tweeter will play down to 8KHz but not lower than that. As you adjust the crossover points, the graph on the RTA screen changes. Our main motive is to adjust the crossover points such that the tweeter gets tuned to high-level frequencies.
- Connect the RTA screen to the car stereo’s mid-range or bandpass frequency output. You will see that the mid-high pass filter is turned off, and it shows a pretty much flat response on the RTA screen.
- Turn on the mid-high pass filter by clicking on the “HPF,” and it will display “HPF On.” Adjust the crossovers so that it covers the mid-range frequencies. The ideal crossover point is 10K, or you can see the frequency ratings on speakers and adjust accordingly.
- In the same way, adjust the crossover points of the low pass filter.
Up to this step, you have tuned midrange, tweeter and now let’s adjust the subwoofer.
- To tune the subwoofer, connect the RTA screen to low-frequency outputs of the car radio. Click on this sign (<) , and it will take you to the subwoofer.
- Adjust the crossover points for the subwoofer to tune the low-level frequencies. For subwoofers, you should set the crossover points at 80Hz.
Zaključek
When switching between network and standard modes, please be aware that just changing modes on the stereo is not enough. You have to completely change your audio system, including the speakers and the amplifier wiring.
Changing modes just on the stereo without other adjustments will damage your speakers if you don’t take time to rewire your stereo, so it is crucial to understand the differences between the standard and the network modes.
