Wiring a line output converter (LOC) is a crucial step in enhancing the audio experience in vehicles, especially when upgrading the sound system. A line output converter is a device that converts the high-level signal from a head unit or amplifier into a low-level signal that can be processed by an external amplifier or signal processor. In this article, we will delve into the world of line output converters, exploring their importance, types, and most importantly, how to wire them correctly for an optimal audio experience.
Understanding Line Output Converters
Before diving into the wiring process, it’s essential to understand what line output converters are and their role in a car audio system. A line output converter is a small device that takes the speaker-level signal from a head unit or amplifier and converts it into a preamp-level signal. This conversion is necessary because most head units and amplifiers produce a high-level signal that is not compatible with external amplifiers or signal processors. The LOC acts as a bridge, allowing the high-level signal to be processed and amplified by external devices, resulting in a cleaner and more powerful audio output.
Types of Line Output Converters
There are several types of line output converters available on the market, each with its unique features and applications. The most common types include:
Line output converters with adjustable gain, which allow users to fine-tune the output signal to match the specifications of the external amplifier or signal processor.
Line output converters with built-in crossovers, which enable users to filter out low-frequency signals and direct them to a subwoofer, resulting in a more balanced audio output.
Choosing the Right Line Output Converter
When selecting a line output converter, it’s crucial to consider several factors, including the type of head unit or amplifier, the external devices being used, and the desired audio output. It’s essential to choose a line output converter that matches the specifications of the head unit or amplifier and the external devices. For example, if the head unit produces a 4-channel output, a 4-channel line output converter should be used to ensure compatibility and optimal performance.
