【HDM2-C-FOUR｜Dedicated Module for Inputting Optical Digital Signals to a Power Amplifier】

While refining the sound of your car audio, you may find that noise gets into the signal path, making the sound’s clarity and quietness less noticeable. HDM2-C-FOUR is a dedicated module designed to input optical digital signals directly into a power amplifier.

Compared to a setup that routes through analog signals, it can significantly reduce noise mixed into the signal. It’s a part well-suited for those who want to hear more detail in the sound, or for those who want to suppress the overall noise character of the system and achieve a calmer, more composed sound.

However, the actual effect and connection method will vary depending on your vehicle’s factory audio, the power amplifier you’re using, and your current system configuration. Even with the same product, the final result can differ depending on where you install it and how you combine it with other equipment.

At Log-On, we don’t decide based on the product alone. Instead, we check your current sound concerns and system setup, and recommend it when needed. Let’s review the direction of your sound together—without unnecessarily adding equipment—while making the most of your current system.
