低音ノブを車に取り付ける方法
重い低音が好きな場合は、音楽の音量を妨げずに低音を上げたいと思うかもしれません.
また、音楽の低音が重くなる場合があり、それを減らして高周波数をより聞き取りやすくすることができます。
低音を調整する最良の方法は、ダッシュボードから直接レベルを制御することですが、低音ノブを車に取り付けるにはどうすればよいでしょうか?調べてみましょう。
一般的に、車内で低音ノブを接続するには、低音ノブの RCA 出力コネクタをアンプの RCA 入力コネクタに接続します。次に、ベース ノブの RCA 入力コネクタを車のヘッド ユニットの RCA 出力コネクタに接続します。
この記事では、カーオーディオに低音ノブを取り付ける方法を紹介します。
バス ノブを車に取り付けるにはどうすればよいですか?
ベースノブの取り付けはタイプによって異なりますが、一般的に、標準的なベースノブの設計では、ヘッドユニットとアンプの間の RCA ワイヤーに接続する必要があるのは RCA ワイヤーのみです。
ただし、使用するベース ノブにカー バッテリー用の追加配線がある場合は、別の接続方法を必要とするベース ノブが必要になる場合があります。
これがベース ノブである場合は、次の手順に従ってください。
- ベース ノブの赤のプラス ケーブルを車のバッテリーのプラス端子に接続します。
- 次に、黒のマイナス ケーブルをバッテリーのマイナス端子に接続します。
- 最後に、車のヘッド ユニットのリモート 電源ケーブルをバス コントロール ノブのオレンジ色のケーブルに接続します。
Bass ノブは、サウンド スペクトルの下部の周波数ミックス レベルを調整します。サブウーファーのノブは、アンプに入る信号のゲインを制御するため、低音を下げても、高音周波数と低音周波数の関係が変わるだけです。
ほとんどの場合、音楽の種類とジャンルに応じて、アンプの設定の高周波数に干渉することなく、低周波数を増減するだけで済みます。
これは、アンプがトランクに配置されているカーオーディオの設置の 99% の場合に特に役立ちます。したがって、運転中にその構成を変更することはできません。
車のハンドルの下やダッシュボードなど、便利でアクセスしやすい場所に低音ノブを取り付けると、この問題の解決に役立ちます。
車や車に取り付けられているその他のアクセサリーに応じて、空のスイッチ パネル、センター カビー内、またはギア シフト ノブの近くのセンター コンソールにベース ノブを取り付けることもできます。
場所によってはツマミだけ出してスッキリと装着できます。
互換性のある低音ノブを選択してください
市場には多くの種類のベース コントロール ノブがあり、それらの主な違いはアンプへの取り付け方法です。
通常、さまざまなカー アンプにはさまざまな接続タイプが付属しており、アンプの接続タイプに一致するベース ノブを探す必要があります。
たとえば、RCA ケーブルを使用するものもあれば、アンプに直接接続するユニバーサル ノブを使用するものもあります。
RCA コネクタを接続する
RCA は、主にビデオおよびオーディオ信号を伝送するために使用される電気コネクタです。ただし、RF コネクタ、DC 電源コネクタ、またはラウドスピーカー ケーブルのコネクタとしても使用できます。
多くの場合、RCA 信号は色分けされています。右オーディオ チャンネルは赤、コンポジット ビデオは黄色、左ステレオ オーディオ チャンネルは白または黒、デジタル オーディオはオレンジ、センター オーディオ チャンネルは緑です。
ほとんどの場合、低音ノブには短い RCA コネクタが付属しており、特にアンプがトランクにある場合は、追加の RCA ケーブルを接続してケーブルを長くする必要がある場合があります。
RCAケーブルを使用してベースノブをアンプに接続することを考えると、ケーブルの品質と太さはベースノブの感度に重要な役割を果たします.
たとえば、RCA ケーブルには、音の歪みを防ぐために適切なシールドが必要です。
また、RCA ケーブルは、車のヘッド ユニットからアンプにライン信号を送信します。ラジオからアンプへの信号はまだ増幅されていないため、RCA ケーブルの抵抗が最終的な低音の質に大きな影響を与える可能性があります。
したがって、高品質で太く、十分にシールドされた RCA ケーブルを使用することをお勧めします。良い例は、ELITE Audio のワイヤーです。 .
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.
結論
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.
よくある質問
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
