What Is A Line Output Converter (LOC)?
A Line Output Converter (LOC) is a device used in audio systems to convert high-level speaker outputs to low-level signals. This conversion is essential when integrating aftermarket amplifiers or other audio components with OEM (original equipment manufacturer) systems that typically do not have dedicated low-level outputs. Essentially, LOCs facilitate the connection between factory-installed head units and aftermarket components without compromising sound quality.
LOCs work by taking the speaker-level signal, which is amplified for driving speakers, and reducing it to a line-level signal suitable for feeding into amplifiers or processors. This process ensures that the audio system can function effectively without damage to either the factory unit or the additional equipment being added. It’s a crucial component in upgrading car audio systems, especially when maintaining the use of an existing head unit.
