Kako namestiti gumb za bas v avto
Če imate radi močan bas, ga boste morda želeli povečati, ne da bi motili glasnost glasbe.
Poleg tega ima lahko glasba včasih močne nizke tone, ki jih boste morda želeli zmanjšati in narediti visoke frekvence bolj slišne.
Najboljši način za nastavitev nizkih tonov je nadzor njihove ravni neposredno z armaturne plošče, toda kako namestiti gumb za nizke tone v avto? Ugotovimo.
Na splošno, če želite priključiti gumb za bas v avtu, vzemite izhodni priključek RCA gumba za nizke tone in ga povežite z vhodnimi priključki RCA ojačevalnika. Nato povežite vhodne priključke RCA gumba za nizke tone z izhodnimi priključki RCA glavne enote avtomobila.
V tem članku vam bom pokazal, kako lahko v avtoavdio namestite gumb za bas.
Kako lahko v avto namestim gumb za bas?
Namestitev gumba za nizke tone je odvisna od njegove vrste in na splošno je treba za standardno zasnovo gumba za nizke tone povezati samo žice RCA z žicami RCA med glavno enoto in ojačevalnikom.
Vendar pa boste morda potrebovali gumb za nizke tone, ki zahteva drugačen način povezave, če ima gumb za nizke tone, ki ga uporabljate, dodatno ožičenje za avtomobilski akumulator.
Če je to vaš gumb za bas, sledite spodnjim korakom:
- Povežite pozitivni rdeči kabel gumba za bas na pozitivni pol avtomobilskega akumulatorja.
- Nato priključite črni negativni kabel na negativni pol baterije.
- Nazadnje povežite kabel za daljinski vklop vaše avtomobilske glavne enote z oranžnim kablom gumba za upravljanje nizkih tonov.
Gumb za bas uravnava nivo mešanice frekvenc v spodnjem delu zvočnega spektra. Gumb nizkotonskega zvočnika nadzira ojačanje signala, ki gre v ojačevalnik, tako da zmanjšanje nizkih tonov spremeni le razmerje med frekvencami visokih in nizkih tonov.
V večini primerov boste morali zvišati ali znižati samo nizke frekvence, odvisno od vrste in zvrsti glasbe, ne da bi posegali v visoke frekvence nastavitev ojačevalnika.
To je še posebej koristno v primeru 99 % avtomobilskih avdio inštalacij, kjer je ojačevalnik nameščen v prtljažniku; zato med vožnjo ne morete spreminjati njegove konfiguracije.
Namestitev gumba za bas na priročno in bolj dostopno mesto, na primer pod avtomobilskim volanom ali na armaturni plošči, bo pomagala rešiti to težavo.
Odvisno od vašega avtomobila in druge dodatne opreme, nameščene v vašem vozilu, lahko gumb za nizkotonce namestite celo v prazno stikalno ploščo, znotraj osrednjega prostora ali na sredinsko konzolo blizu prestavnega gumba.
Odvisno od vaše lokacije ga lahko pritrdite tako, da je prikazan samo gumb.
Izberite združljiv gumb za bas
Na trgu je veliko vrst gumbov za upravljanje nizkih tonov, glavna razlika med njimi pa je, kako se pritrdijo na ojačevalnik.
Običajno so različni avtomobilski ojačevalniki opremljeni z različnimi vrstami povezav in poiskati morate gumb za nizke tone, ki se lahko ujema z vrsto povezave ojačevalnika.
Nekateri na primer uporabljajo kable RCA, medtem ko so drugi univerzalni gumbi, ki se priključijo neposredno na ojačevalnik.
Priključite priključke RCA
RCA je električni priključek, ki se uporablja predvsem za prenos video in avdio signalov. Vendar pa ga lahko uporabite tudi kot priključek RF, napajalni priključek za enosmerni tok ali kot priključek za kable zvočnikov.
Signali RCA so pogosto barvno kodirani:rdeča za desni avdio kanal, rumena za kompozitni video, bela ali črna za levi stereo avdio kanal, oranžna za digitalni avdio kanal in zelena za osrednji avdio kanal.
V večini primerov ima gumb za nizke tone kratke priključke RCA in morda boste morali povečati dolžino kablov s priklopom dodatnih kablov RCA, še posebej, če je vaš ojačevalnik v prtljažniku.
Glede na to, da boste za povezavo gumba za nizke tone na ojačevalnik uporabljali kable RCA, bosta kakovost in debelina kabla igrali bistveno vlogo pri občutljivosti gumba za nizke tone.
Na primer, kabli RCA morajo imeti ustrezno zaščito, da preprečijo popačenje zvoka.
Poleg tega bo kabel RCA prenašal linijski signal od glavne enote avtomobila do ojačevalnika. Ker signal od radia do ojačevalnika še ni ojačan, lahko upornost kablov RCA pomembno vpliva na končno kakovost nizkih tonov.
Zato je priporočljivo izbrati visokokakovostne, debele in dobro oklopljene kable RCA. Odličen primer so žice iz ELITE Audio .
When you have the correct RCA wires in hand, attach the signal outputs (blue and white) to the amplifier and then RCA signal inputs (red and green) to the car head unit.
Although this color coding might differ with the brand, in most cases, the bass knob will have a label on the output and input connectors.
Connect the Remote Turn-On-Cable
The turn-on cable is the remote wire located behind the head unit. For most car radios, it is a blue and white cable coming from the back of the stereo harness.
When you turn on the car, this cable provides the amplifier a signal when to turn on.
If you however connect this cable to another wire in the vehicle with a constant voltage, the amplifier will remain on even when you will turn the engine off, so it is important to remember that it should be connected only to the car radio.
When you turn the car’s ignition off, the remote wire stops transferring current, and the amplifier switches off.
You need to hook up the remote turn-on-cable from the back of the stereo to the orange cable (remote in) in your bass control and then connect the blue wire to your amplifier.
Set the Head Unit and Amplifier Bass to Medium
Considering that you will adjust the bass of your car stereo system using the bass knob and not the amplifier or the car head unit other than the volume, you need to set the bass to medium.
However, for the best bass experience, it is advisable to remove the sound distortion from your stereo system.
Minimize the Gain in the amplifier, and then increase the volume of your head unit until you hear some sound distortion.
In most cases, you can minimize the Gain by turning the knob to the counterclockwise direction and maximize it by turning the knob in the clockwise direction.
Usually, this is the maximum volume that you can use in your head unit without sound distortion.
You can also opt to use ⅔ of your car head unit’s maximum volume as your maximum volume settings.
- Minimize the Gain in your car head unit and increase the Gain in your amplifier until you hear some sound distortion. Typically, this is the maximum Gain you can set in your amplifier without hearing any sound distortion.
- Note these settings as they are the maximum volume settings you can use without sound distortion.
- Now, increase the amplifier and the head unit gain to these levels, turn the amplifier bass to the lowest position, and increase the bass using the bass knob to the top position.
- Note that some universal bass knobs come with a rotary push turn switch for turning them on and off, so ensure the best knob is on.
- In most cases, the knob will have an indicator light to indicate when it is in its top position. Start increasing the amplifier bass while listening to sound distortion.
- If the amplifier bass knob causes a sound distortion before reaching the middle line, minimize it slightly and leave it at this level.
- On the other hand, if the amplifier bass knob gets past the middle line before causing sound distortion, set it at the centerline.
If you have a bass boost in your system, turn it up carefully to avoid sound distortion.
Keep in mind that a bass boost can cause damage to your car amplifier or subwoofers if you fail to set it correctly. Therefore, it is advisable to leave your bass boost with the default settings or at zero Gain.
If it is a must you use it, it is also advisable not to use it in both the amplifier and the car head unit at the same time.
With these settings, you can now use your bass knob to increase or reduce the bass with the sound remaining clear.
Can I Use Any Bass Knob for My Amplifier?
Bass knobs are in general, universal devices. However, in most cases, they work in the best way when they are from the same manufacturer as the amplifier.
This compatibility is because they have similar physical characteristics, and the signals and circuitry from the bass knob to the amplifier are the same for similar models.
Bass knobs and amplifiers from different manufacturers might not work because some use standard phone jack plugs while others use standard plugs.
Additionally, their signals and circuitry are usually different, with varying current demand and voltage levels.
On the other hand, there are universal bass knobs that work with almost any amplifier on the market. Some of the universal bass knobs also come with a multimeter that can help you monitor the power usage of your car’s electrical system.
These types of bass knobs also come with two extra cables, the red one connecting to the car battery’s positive terminal and the other black to the ground or negative terminal.
Does Bass Knob Affect Gain?
Understanding what a bass knob does to your audio signal is essential. Typically, a remote subwoofer control is an external gain that allows you to fine-tune your music to achieve the bass level of your desire.
Connecting it to your amplifier essentially means avoiding the gain control in the amplifier.
Generally, turning the bass knob up means adjusting the audio signal that your subwoofers are receiving. So, excessive turning up of the gain control may result in sound distortion and clipping.
The purpose of the gain control is to determine how far you can increase the head unit’s volume for the amplifier to reach its maximum power.
A correctly set gain prevents damage to the subwoofer and reduces distortion and background noise.
If you set the Gain excessively high at higher voltages sources, your amplifier reaches its maximum power at a reduced volume control configuration from the source unit.
On the other hand, if the gain settings are too low, the amplifier will not be in a position to reach maximum power, and the sounds will be weak.
Usually, this makes the source unit clip resulting in the delivery of the distorted signal to the speakers. Low gain settings are ideal for sources with lower than 2.5 voltage.
Unlike volume, which is the power of the outgoing signal from the amplifier, Gain refers to the power of the input signal from the car head unit.
That means that the bass knob will be affecting the frequencies at the gain level but not volume.
For instance, when you use the bass knob to reduce the bass, you will be reducing the low-frequency gain without affecting the high-frequency reaching the amplifier.
Zaključek
After installing a high-end aftermarket car head unit, high-quality amplifier, and subwoofers, you will want a convenient way to control the bass on the system.
The most viable option is to install a bass knob between the car head unit and the amplifier.
To make it correctly, first look for the most convenient and easy to reach location in your car, and then use the above step-by-step guide to install the bass knob.
Pogosto zastavljena vprašanja
Can Bass Boost Lead To Clipping?
Bass boost can lead to sound clipping, and in fact, it is the main cause of clipping. Typically, every time you increase your bass boost by 3 dB, the amplifier will need to double the power output at the same volume.
For instance, if music is recorded at 0 dB and you set your amplifier’s bass boost to +9dB, you may force the amplifier to produce thousands of watts over its capacity.
If the amplifier cannot produce this power, it will try to amplify but with a lot of distortion, causing the clipping.
How Can I Minimize My Subwoofer Distortion?
You can minimize subwoofer distortion by using low bass and Gain or using High Pass Filters for your subwoofer.
The filters help to eliminate the low bass and distortion, delivering a more clean and clear sound.
Car subwoofers might also be distorted because you don’t have an amplifier, or your amplifier is not producing enough power.
The best solution would be to upgrade the amplifier to one with sufficient power.
Can Bass Damage My Subwoofers?
Excessive bass can damage your car subwoofer, especially if played at a high volume for a long time.
The damage occurs due to over-excursion when the subwoofer’s cone is forced to move way beyond its limits.
This, however is not the easiest to clarify, and it depends on the following:
- how low the frequencies are
- at what volume they are being played
- the power of the amplifier
- the size and type of the subwoofer
