【BRAX DSP BLACK｜A High-End DSP Processor That Precisely Tunes In-Car Sound with a High-Precision DAC and 64-Bit Processing】

BRAX DSP BLACK is for those who want to take the amount of audio information, soundstage imaging, and the sense of separation between instruments to the next level with a factory audio system or an existing car audio setup.

This processor is equipped with three 64-bit audio signal processors and performs internal processing at 192kHz/32-bit. For D/A and A/D conversion, it uses premium AKM DACs. Designed to accurately depict everything in the cabin—from the subtle nuances of vocals and the lingering decay of instruments to the quiet moments when no music is playing.

Not only does it increase volume to deliver impact, but it also makes the fine details within the songs you listen to every day easier to hear, bringing changes to soundstage coherence and overall listenability. It’s a DSP well-suited for those who want to enjoy music on long drives, as well as for anyone who wants to further refine the entire system after replacing speakers and/or an amplifier.

Inputs include 8ch high-level and 8ch RCA, with support for coaxial and optical digital as well. With up to 12ch of RCA outputs, it can support a wide range of system configurations, including front 2-way setups and subwoofers. Ease of considering future system upgrades is also one of the attractions of the BRAX DSP BLACK. It supports digital transmission via expansion modules, enabling growth aligned with your system direction.

However, a DSP doesn’t determine sound quality by the unit’s performance alone. You must adjust it while considering the factory system specific to your vehicle, the combination of speakers and amplifiers, how you extract the signal, and how each speaker is connected. Even with the same BRAX DSP BLACK, the final result will differ depending on your setup and installation approach.

At LOGON, we’ll help you organize whether adding a DSP makes sense and where it’s most cost-effective to invest for noticeable effects—based on how you use your car, the music you typically listen to, your current system, and what you want to do next. If it were me, I wouldn’t decide only the equipment from the start; I’d consider the whole vehicle and system, then design a configuration that leverages the BRAX DSP BLACK’s performance.

If you want to “tune the factory sound to be a bit more natural,” “finish the sound properly after replacing speakers,” or “push detailed adjustments with a high-performance DSP,” please feel free to consult us. While listening to music inside the car, let’s think together about a system direction that fits your needs.
