Are you thinking of installing or upgrading your car audio system? Connecting aftermarket amplifiers to factory head units is one of the common problems faced by car owners in such cases. However, line output converters and high to low converter car audio systems are useful devices in such cases. Both of these systems have similar purposes although the usage and functions are slightly different. You have to understand the differences between them to ensure seamless integration in your car audio system and achieve clean sound quality.
What is a High to Low Converter?
It is a device that transforms high-level (speaker-level) audio signals from a factory head unit into low-level (RCA) signals, which are compatible with aftermarket amplifiers. Most of the factory stereos that you can find on the market lack RCA outputs which are necessary for external amplifiers. This gap is bridged with the help of a high to low converter.
When it comes to high to low converter audio, this device steps down the powered signal from your factory speaker wires to a signal that can go into your aftermarket amplifier safely, without overloading it. This can ensure clean transmission of signals, with no loss or distortion of signal.
What is a Line Output Converter?
Often just referred to as a LOC, a car audio line out converter is actually just like a high to low converter. It is also responsible for the conversion of speaker-level signals to RCA outputs. But LOCs often have better signal processing and adjustable gain controls. Naturally, these are a more refined solution for stock stereo integration with high-performance car amplifiers.
In premium car audio installations, a car audio line-out converter can manage to reduce noise as well as maintain signal fidelity. Some models also have auto turn-on features or built-in load resistors which make them more versatile solutions as compared to basic high to low converters.
High to Low Converters and Line Output Converters: What are the Top Differences?
The terms are used interchangeably at times in the car audio converter market, but there are subtle variations when it comes to design, features and performance.
-
Design and quality
The design of high to low converters is simpler. Generally, these are passive devices with no external source of power. On the other hand, line output converters are often more advanced. These may need a 12V power connection for remote turn-on, signal sensing or other features.
-
Signal Processing
Often, LOCs have various features such as improved signal filtering, adjustable output levels and ground loop isolation. Due to these features, sound output is cleaner – which is essential for high-fidelity systems.
-
Use Case
If you are planning to do a simple upgrade and add a subwoofer or amp, it will be enough to go for a high to low converter car audio setup.
However, if you want to preserve sound quality and are going for high-end amplifiers and speakers, it will be better to go for a car audio line out converter.
If you are looking for an affordable and straightforward upgrade, it may be a good idea to go for a high to low converter. But if you need a superior system with more focus on audio clarity, particularly at higher volumes, choose a good car audio line-out converter.
