【HDM1-C-ONE｜Dedicated Amp Module for Optical Digital Connections】

HDM1-C-ONE is designed for anyone who wants to refine their car audio sound to be clearer. It is a dedicated module that inputs optical digital signals directly into the power amplifier.

With typical connections, noise may be mixed into the audio signal depending on the vehicle-side power supply and wiring environment. By using the HDM1-C-ONE to send the optical digital signal directly to the power amplifier, you can significantly reduce noise contamination along the signal path and create a quieter, cleaner sound background.

If you want to hear the finer details of the audio more clearly, or if you’re concerned about a sense of noise in your current system, it’s important not to replace only the amplifier, but to review how you extract the signal as well. If I were advising you, I would first check your vehicle-side audio configuration and how it pairs with your existing amplifier, and then determine whether there is real value in using the HDM1-C-ONE.

Even with the same product, the final result can vary depending on where you take the signal from and how you connect it. At LOGON, we make proposals focused on the necessary parts while confirming your vehicle model, system configuration, and the specific audio issues you’re currently experiencing. If you’re concerned about audio noise or the connection method, please start by letting us hear your current system. Let’s think together about practical improvement steps.
