【audison bit One HD Virtuoso｜A Car-Audio DSP that Tunes Sound While Keeping Your OEM Audio】

For those who want to evolve into a more serious car-audio system—such as replacing speakers and adding a subwoofer—while keeping the functions and usability of the factory audio as-is, the product to consider is audison’s bit One HD Virtuoso.

This unit is a car-audio digital signal processor (DSP) that lets you finely adjust sound timing errors that occur inside the cabin and the balance between individual speakers. It processes the audio signals taken from the OEM system to match the in-car environment, tuning the vocalist’s position, the separation of instruments, and the seamless connection from bass to treble.

You’ll notice differences not only when you turn the volume up, but also when listening to your usual tracks at your normal everyday volume—especially in how cohesive the sound is and how easy it is to listen to. Aiming for a presentation where the treble goes cleanly toward a more information-rich direction, while the bass maintains good responsiveness and the overall balance is refined. Another appeal of this DSP is that it supports high-resolution audio sources and offers internal processing up to 96kHz / 24bit.

For inputs, it provides two optical digital inputs and 12-channel analog inputs. Since it supports 13-channel digital outputs, it’s well-suited for systems that combine multiple amplifiers, speakers, and subwoofers—while using OEM audio as the base. Using PC software, you can make detailed settings tailored to your vehicle and system configuration.

However, a DSP is not a product where the sound is completed simply by installing the main unit. Which signals are extracted and sent to which equipment—how it’s integrated with the vehicle’s OEM system—also matters. Furthermore, the final result will vary depending on the installation method, wiring work, and how the ultimate adjustments are performed.

At LOGON, we consider a practical, no-drama configuration together, while confirming your vehicle model and OEM audio specifications, your current system, the kind of music you usually listen to, and the sound direction you want to achieve. If I were advising you, I would rather ask first about your dissatisfaction with your current sound and how far you want to develop the system in the future, and then judge whether it makes sense to use this DSP—before deciding on the product.

If you want to enjoy sound that takes a step beyond OEM audio, if you find that overall balance doesn’t come together even after replacing speakers or amplifiers, or if you plan to expand your system in the future, please feel free to consult us. We’ll guide you based on your vehicle, including both the installation details and the adjustment approach.
