【M-5.4 DSP MKⅡ｜5ch Power Amplifier with 9ch DSP to Tune OEM Audio】

You want your OEM audio to have a bit more body and a wider sense of soundstage, but you’d rather not replace the navigation system or the factory setup on a large scale. If that sounds like you, consider the M-5.4 DSP MKⅡ.

Packed into a compact body, it combines a 9ch DSP and a 5ch power amplifier, allowing you to finely tune the audio signals taken from your OEM system to match your in-car speaker configuration. In particular, even signals that are output separately to each speaker—as with factory multi-systems—can be level-adjusted while mixing up to 4ch of inputs, making it easier to bring the overall sound together.

Use the DSP to balance the sound, and drive the speakers properly with the built-in amplifier. Plus, it features 4ch pre-outs, so if you want to add external amplifiers or a subwoofer in the future, it will be easier to expand and develop your system. The digital input supports 96kHz/24bit formats, and when paired with compatible equipment, you can build a system that takes advantage of even more detailed audio information.

The M-5.4 DSP MKⅡ is not a product that will produce the exact same sound just by installing it. How you extract the signals from the OEM audio, and how you assign them to the speakers—these will determine the direction of the tuning. It changes depending on the vehicle model and OEM system configuration, the condition of the speakers, and the music you typically listen to.

At LOGON, we don’t aim only to install a product. We propose a practical, no-stress configuration by checking which parts of your current system can be used and which parts would benefit from adjustments. If you’re going to introduce a DSP amplifier, we want to tune it together—not stopping at simply making sound, but getting you to a point where you can enjoy your usual songs comfortably in the car.
