What Is A Line Output Converter and How Does It Work?
A car stereo system often consists of three main components. These include the radio (or head unit), an amp, and the speakers. When you turn on your stereo, you may think that sound is automatically sent to your speakers, but there is a lot behind the scenes.
To begin with, the head unit produces the initial audio signal. This signal is usually fragile and thus passed through a preamp, which amplifies just a little higher. The signal goes to your amplifier from the preamp, where it is now given a mega boost. The signal is now transferred to the speakers. The vibrations from the speakers then generate the sound you usually hear.
Without a preamp, your amp will often be underutilized, and their sound output will never be good enough. Sadly, that’s often the case with a majority of factory stereo systems. If you want to get the best from your factory stereo, that’s where a line output comes into play.
A LOC (abbreviation for line output converter) taps the signal coming from your head unit and amplifies it before sending it to the amplifier. The speakers will now produce louder, more detailed, and clearer sounds. Enjoy a new boom and better sound without having to replace your radio.
Types of Line Output Converters
There are two types of LOCs:
- Passive converter
- And an active converter
A passive converter works by reducing the voltage received from the speaker wires. These do not need power from an external source. But on the flip side, because they can only scale down the signal received from the radio, a weak signal means you’ll as well get low sound output.
On the other hand, an active converter controls the signal they’ll pick from your radio. On top of that, they’ll include additional features such as remoter turn-on, bass restoration, and more. And because they can take up a high voltage of up to 400Watts, active converters are perfect for high-powered radio systems. That explains why active converters are a favorite among most audiophiles.
Factors to Consider for Best Quality Line Output Converters?
Now you know the definition of a line output converter and the science behind its functioning. Next, we will look at the two main factors you should consider when choosing the best quality Line Output Converters for your stereo system.
Number of Input/Output Channels
A basic LOC will have a minimum of 2 input channels and 2 output channels. On the other hand, more advanced options can have up to 6 input and 6 output channels.
The number of channels refers to the number of speaker output lines from your radio that the LOC can connect to.
If you want to have the flexibility of connecting your LOC to several speakers, choose one with a higher number of input/output channels.
Output Levels
This is another equally important factor that you should consider. It refers to the voltage degree rating on your LOC. Choose a rating that is equal to that of your amp. If you connect a LOC that has a higher rating, you’ll have to deal with a blown-up amplifier pretty soon.
Frequently Asked Questions
Getting the best quality sound from your sound system is a complex task. It is natural to have plenty of questions while fine-tuning your audio. Here is a quick look at some of the most frequently asked questions others had about adding an output converter to their audio systems.
Do factory radios have preamp outputs?
Most factory radios do not come with a preamp output but some advanced models might include this feature. It is possible to add a preamp output to your existing car radio if you like the look and functionality of your current radio or if you don’t want to go through the hassles of removing it from the vehicle dashboard. Line outputs usually include the needed connectivity so you can easily tap into the speaker wires.
Why is there a huge price difference in line output converters?
Line output converters usually vary in price because more expensive models tend to offer additional features and can handle more power than cheaper models.
Before you choose the right converter for you, calculate the total power output of your car radio. For example, the AudioControl LC2i on our list can accept 400-watt signals per channel while the cheaper Kisloc 2-channel converter on our list can only handle 50 watts of input.
The feature differences can also have a huge impact on your converter functionality. Converters with a higher preamp output voltage will keep audio signals to your amp clean and distortion-free. Some advanced models also include equalizers or bass restoration circuitry which will improve sound quality a great deal.
Do all amps need a line output converter?
No, some amps can function perfectly well without a converter. Amplifiers with speaker-level inputs can tap into existing speaker wires without a converter. Some subwoofers also include speaker-level inputs. With these advanced amps and subwoofers, the conversion occurs inside the device. It is best to check out the specs of your amp before you decide to buy an additional line output converter.
Is it better to get an amp with speaker level input or to get a line output converter?
This can vary based on the type of LOC you are considering. For more basic and cheaper line output converters, the features they offer are already included in the amp design. Advanced LOCsoffer additional features like onboard equalizers, a higher watt input capacity, a higher output capacity, and a wider frequency response range. These added features can make a huge difference in your sound quality.
FINAL THOUGHTS
Tired of listening to some mediocre sound from your factory stereo system, but for one reason or another, you aren’t in a position to replace your head unit just yet?
A line output converter is the best solution to your problems. It will help you to tap into the maximum potential of your amp for improved performance.
We hope this guide equips you with all the info you need in choosing the best quality line output converter!
