What Is a Line Output Converter?

A line output converter, or LOC, is a device used to convert a vehicle’s higher-level audio signal into a lower level one. It is often used to add an aftermarket amplifier to a car stereo system. It is sometimes referred to as a line level converter or speaker level converter.

The purpose of a LOC is to take the amplified signal from the car stereo head unit, and convert it into a low-level preamp signal suitable for use with an aftermarket amplifier. Without a line output converter, the signal from the head unit would not be strong enough to power an aftermarket amplifier. In addition, it could cause distortion or other problems.

Why Do I Need a Line Output Converter?

The main reason you need a LOC is because factory car audio systems are not designed to be compatible with aftermarket amplifiers. The signal from the head unit is too strong and will cause the amplifier to distort. This is where the line output converter comes in; it converts the higher-level head unit signal into a lower-level preamp signal suitable for use with an aftermarket amplifier.

Another reason why you may need a line output converter is if you want to retain your factory head unit. Many aftermarket amplifiers require a low-level preamp signal, so if you want to keep your factory head unit, you will need to install a line output converter in order to make it compatible.

How Does a Line Output Converter Work?

A line output converter works by taking the high-level signal from the car stereo head unit, and converting it into a lower-level preamp signal. This process involves several steps, including voltage conversion, signal conditioning, and impedance matching.

The first step in the process is voltage conversion. This is where the LOC takes the high-voltage signal from the head unit and converts it to a lower voltage signal that is suitable for use with an aftermarket amplifier.

The next step is signal conditioning. This involves using voltage and frequency filters to remove any unwanted noise or interference from the signal.

Finally, the last step is impedance matching. This is where the LOC matches the output impedance of the head unit with the input impedance of the amplifier.

What Are the Different Types of Line Output Converters?

There are two main types of line output converters: active and passive. An active line output converter is powered by the vehicle's electrical system, while a passive converter relies solely on the signal from the head unit.

An active line output converter is usually more powerful and provides a stronger signal than a passive converter. However, active converters require more installation time and may require additional hardware such as signal splitters and line drivers.

In addition, there are also universal line output converters, which are designed to be compatible with any vehicle. Universal converters do not require any additional hardware and can be quickly and easily installed.

How Do I Install a Line Output Converter in My Car?

Installing a line output converter in your car is relatively simple, although it can vary depending on the type of vehicle and converter you have. Generally speaking, the process involves connecting the LOC to the vehicle's wiring harness, connecting the output wires to the amplifier, and then mounting the converter.

It is important to note that the LOC should only be connected to the car stereo's output wires. If you connect it to the power wires, it could cause damage to the car's electrical system.

Once the LOC is connected and mounted, you can then test it to ensure that it is working properly. You can do this by playing music through the car stereo and listening for any sound coming from the amplifier.

What Are the Benefits of Using a Line Output Converter?

Using a line output converter can provide several benefits. First, it allows you to retain your factory head unit while still being able to use an aftermarket amplifier. This can provide a cleaner and more powerful sound than using just the head unit alone.

Second, it can help protect your car’s electrical system from damage. Because the LOC reduces the voltage of the head unit’s signal, it prevents the amplifier from drawing too much power from the vehicle’s electrical system.

Finally, a line output converter is relatively easy to install and use. It does not require any additional hardware and can usually be done in a matter of minutes.

Are Line Output Converters Universal?

While there are some universal line output converters available, they may not be compatible with all vehicles. It is important to check the specifications of the converter before purchasing to make sure it is compatible with your vehicle.

In addition, some line output converters may require additional hardware such as signal splitters or line drivers. It is important to check what hardware is required before attempting to install the converter.

Can I Use a Line Output Converter with a Factory Head Unit?

Yes, you can use a line output converter with a factory head unit. As long as the converter is compatible with your vehicle, you should be able to use it with a factory head unit.

However, it is important to note that the factory head unit must be able to provide a strong enough signal to power the converter and amplifier. If the head unit is not able to provide a strong enough signal, you may need to replace it with a higher-end head unit.

How Do I Choose the Right Line Output Converter for My Car?

When choosing the right line output converter for your car, there are a few things to consider. First, you need to make sure the converter is compatible with your car. You should also make sure the converter has enough power to provide a strong signal to your amplifier. Additionally, you should make sure the converter is easy to install and use.

Finally, you should make sure the converter is within your budget. There are many different types of line output converters available, ranging from basic models to high-end models. It is important to find one that is within your budget while still providing the features and performance you need.

By taking the time to research and compare different line output converters, you can find the right one for your car and get the most out of your audio system.
