【UP-10DSP｜DSP amplifier that refines sound while preserving OEM audio】

You may want a bit more thickness to the sound of your factory audio, bring the vocals forward more naturally, or find that even after replacing the speakers, everything doesn’t come together the way you expected. When that’s the case, you should consider the DSP amplifier UP-10DSP.

UP-10DSP is a processor amplifier that integrates an 11ch DSP and a 10ch power amplifier. By finely adjusting the signal extracted from your OEM audio to match your in-car speaker configuration, it is designed to be easy to apply even to multi-channel OEM systems, such as front, rear, center, and subwoofer setups.

The high-level input supports 8ch by default, and if you use the separately sold MEC ANALOG IN, it can also support high-level input totaling 10ch. In addition, since you can mix and adjust the level of input signals from up to 4 channels/lines, you can combine each signal from the OEM multi-system and treat them as a more full-range-like signal.

For sound adjustment, you configure settings such as the volume, frequency, phase, and time alignment of each speaker to suit the vehicle interior. It’s not just about raising the amplifier output—DSP amps also let you fine-tune the overall balance inside the car, for example by adjusting the vocal position from the driver’s seat and tuning the bass so it connects naturally with the front speakers.

The UP-10DSP is suited for people who want to refine the sound while keeping the OEM audio, and for those who want to get even more out of speaker replacement. However, since the configuration of the OEM amplifier and how signals are tapped differ by vehicle model, even with the same product, connection methods and adjustment contents will vary.

At Logon, we design the configuration to match your vehicle model, OEM system, the speakers you’ll use, and the music you usually listen to. A DSP amplifier is not something you simply install and forget; the final sound depends on how you actually adjust it inside the car. If it were me, I wouldn’t decide based on the product alone—I would first confirm what you want to change in your current system, and then organize the necessary configuration together.
