【BRAX DSP SILVER AKM DAC | High-End DSP Processor for Fine-Tuning Audio Inside the Car】

You want a bit more information in the sound of your factory audio, you want vocals to appear naturally right in front of you, and even after replacing the speakers, the sound doesn’t come together as you expected inside the vehicle.

In such cases, what matters is not just the speakers, but a DSP that carefully adjusts the sound to match the in-car environment.

BRAX DSP SILVER AKM DAC features three 64-bit audio signal processors and is a high-performance digital processor that performs internal processing at 192kHz/32bit. For D/A and A/D conversion, it uses premium AKM DACs, designed to handle fine musical details and even the tail of the sound with care.

This isn’t the kind of unit that only delivers punch when you turn the volume up. By sorting out, one by one, the expressions of the vocals, the spatial relationships of instruments, and how the bass extends, the impression of the songs you listen to every day will change. It’s a processor that makes musical details easy to hear even at low volume, and is well-suited for those who want to enjoy music on long drives.

Input/Output Configuration Easy to Match Your System Build

For inputs, it provides 8-channel RCA and also 8-channel high-level inputs that can capture signals from factory audio and similar sources. Since it supports coaxial and optical digital inputs as well, it’s easy to consider realistic connection methods to suit your vehicle’s factory system or existing car audio setup.

For outputs, it supports RCA output up to 12 channels. You can broaden the range of adjustments to match the system size and speaker configuration—front, rear, center, subwoofer, and more. By using an expansion module, you can also support digital transmission.

However, having more channels doesn’t automatically mean better sound. Depending on the vehicle model and the specifications of the factory navigation, the number of speakers, the amplifier configuration, and how you normally listen, the required input/output and adjustment methods will vary.

With a DSP, the Final Result Depends on Installation and Tuning

A DSP is not a product where you simply connect the main unit and you’re done.

You need to adjust the balance and arrival time of the sound from each speaker to suit the interior of the car, so that the entire system connects naturally. The final impression also changes depending on the installation method, how you extract the signal, and the combinations with amplifiers and speakers.

To take advantage of the performance of the BRAX DSP SILVER AKM DAC, it’s important not to choose it based on specifications alone, but to first organize how far you want to fine-tune the sound in your current vehicle. If it were me, I would check the overall system configuration—including the speakers and amplifiers—then decide how to use this DSP.

At LOGON, from setups that make use of the factory system to full-fledged systems combining multiple amplifiers, we work with you to determine the direction while considering your vehicle model, how you use it, your sound preferences, and your budget.

Sound changes aren’t always easy to understand from catalog numbers alone. Please tell us what you’re concerned about with your current sound, and what music you often listen to. We’ll propose a realistic solution starting from the parts where spending money actually makes sense—without forcing you to switch to a significantly larger system.
