【M25-IN | MOST25 Optical Interface for Digital Input of Factory Audio】

The M25-IN is designed for people who want to fine-tune the sound inside the car using a DSP while making the most of the factory audio. It is an optical interface that directly extracts the digital audio signal from factory audio that uses MOST25 and inputs it into the corresponding DSP.

The key point of this module is that, rather than converting the factory audio to analog and then capturing it, it can send digital signals in bit-perfect mode. Even if you are considering improving sound quality based on the factory system, how you build the audio “input path” will affect the subsequent DSP adjustments and the overall final result of the system.

It can accept up to 8 channels and is compatible with A-DSP, J-DSP, T-DSPmk2, and M-DSP. This is the part you should consider if you want to input digital signals to the DSP from the factory audio in a more suitable form.

However, actual compatibility and connection methods need to be confirmed depending on the factory audio specifications of your vehicle and your current system configuration. I think it’s best to consider the overall setup not only by adding the M25-IN, but also by looking at the combinations with the DSP, amplifier, and speakers, and how far you want to refine the sound inside the cabin. At Logon, we organize the direction for each vehicle while listening to your preferences—whether you want to make use of the factory system, increase the amount of sonic information, make vocals easier to listen to, and so on.
