【PP-62DSP DSP Amplifier｜Refine your in-car sound while keeping your factory audio】

Even if you’re not fully satisfied with the sound from your factory audio, there are many cars where you can’t replace the navigation system or head unit. PP-62DSP is a DSP amplifier that digitally processes the audio signal input from the factory speaker line, allowing you to finely tune it to match the acoustic characteristics inside the vehicle.

It integrates a high-low converter, A/D converter, signal processor, D/A converter, and an 8ch power amplifier. While making use of the factory system, it becomes easier to balance the sound and align how each speaker connects.

For example, issues such as vocals feeling a little too far away, bass becoming muddy, or getting fatigued when you turn up the volume may be improved through in-car settings tailored to your vehicle. It’s a unit suited for people who want to bring the music they always listen to closer to a more natural, easy-to-listen sound.

A DSP amplifier doesn’t determine the sound just by installing the main unit. Depending on the factory system and speaker configuration for each vehicle model—and on how you combine the installation method with audio adjustments—the final results will differ. At LOGON, we discuss together whether a configuration that uses the PP-62DSP makes sense, taking into account how you use your car and your preferences.

If you want to improve sound while keeping your factory audio, if swapping speakers alone didn’t deliver the sound you like, or if you want to keep future system upgrades in mind, please feel free to consult us. Let’s organize a sensible direction while checking your vehicle and factory system.
