【AT-HLC230｜A High-to-Low Converter That Adds Line Output to OEM Audio】

When you want to add an external amplifier or subwoofer to a factory car navigation system or a head unit that does not have line outputs, you may not be able to connect the speaker outputs directly.

AT-HLC230 is a high-to-low converter that converts the head unit’s speaker output into a line output. It helps when you want to build upon your OEM audio and develop a system that combines it with an external amplifier, etc.

Because it features a gain control function, you can adjust the level to match the connected equipment and the output from the vehicle side. Designed with consideration for potential impact on sound quality, it is a product suited for those who want to step up from the factory system without going too far.

A sturdy metal body and compact size are also convenient points. That said, the actual results are not determined by the converter alone; they can also vary depending on how you extract the signal, how you handle power and wiring, and compatibility with the amplifier you connect.

At LOGON, we review the vehicle model and the specifications of the OEM audio, as well as the equipment you plan to add next, and we organize the necessary configuration together. If you’re considering adding an external amplifier or subwoofer but don’t want to replace your factory navigation system, please feel free to consult us.
