【PP-41DSP for UNIVERSAL | 4ch DSP amplifier that enhances factory audio】

You’d like a bit more spaciousness and information from your factory audio, but you don’t want to make major changes to your navigation system or head unit. That’s exactly what PP-41DSP for UNIVERSAL is for.

All-in-one integration of a high/low converter, A/D converter, signal processor, D/A converter, and a 4ch power amplifier. This DSP amplifier digitally processes the incoming music signal and adjusts the sound balance to match the speakers in your vehicle.

Supports a 56-bit processor, 172 MHz clock frequency, and 48 kHz / 24-bit sampling rate. Using high-quality 24-bit A/D and D/A converters along with operational amplifiers, it achieves a harmonic distortion of 0.03% or less and an S/N ratio of 100 dB or higher.

A DSP amplifier doesn’t determine the sound quality just by installing the main unit. It’s important to check the input signal and fine-tune the sound according to your vehicle’s factory system, speaker configuration, and installation conditions. Even with the same product, the final result can differ depending on the connection method and settings—so if I were to do it, I would confirm the actual vehicle and current system first, then propose a reasonable configuration.

Compatibility and connection methods must be confirmed based on the vehicle specifications. Connecting the PP-41DSP for UNIVERSAL Edition 1.0 requires a separately sold adapter cable. If you’re considering installation, please let us know the vehicle model, year, and your current audio setup. While confirming everything, let’s think together about how much you can change/improve the sound.
