【A-DSP 8ch Signal Processor | Car Audio DSP That Brings Out Musicality and Tuning Ability】

When you listen to music in your car, simply replacing the speakers or amplifier may not make the sound come together as you expected.

When the left/right sound positioning doesn’t line up, vocals become blurry, only the bass stands out, or the adjustment range is insufficient when combined with the factory system—A-DSP is an 8ch signal processor designed to create fine-tuned sound tailored to the car’s acoustics.

The D/A converter uses the AK449X. In addition, it is equipped with the ADAU1452 processor from Analog Devices, allowing you to adjust the incoming signals according to your car’s speaker configuration and your preferences.

This is not a device meant only to increase volume. It helps balance left/right differences caused by speaker placement and the shape of the cabin, and aligns the balance across frequency ranges so that vocal and instrument positions come together naturally. Even with music you always listen to, when the arrangement and how it sounds changes, you may find yourself wanting to listen again.

For digital input, it supports TOSLINK and COAXIAL, and the RCA output provides 8 channels. Depending on your system setup, you can individually tune multiple speakers such as front, rear, and subwoofers.

It’s also notable for its expandability: you can optionally add a USB audio module based on Amanero or XMOS, a Bluetooth module, analog input, the MOST25/MOST150 interfaces, and more. Whether you want to take advantage of the factory system in your vehicle or expand your input options later, you can combine modules while considering the overall configuration.

However, a DSP is not a device that’s finished just by installing the unit. The final result changes significantly depending on which signals are input, how they are assigned to which speakers, and how you adjust them inside the car.

At LOGON, we propose a practical, no-compromise configuration by checking your vehicle model and factory system, the speakers and amplifiers you use, and the music you usually listen to. We’ll organize the direction together—not only what you can do with the A-DSP, but also how far you need to go to feel the effect more easily.

In online shopping, we offer only the A-DSP unit itself. If you’re considering installation, system configuration, and tuning as well, you’ll need to confirm based on your vehicle’s specifications. If you tell us about your sound concerns and the direction you want to achieve, we’ll think together about the best way to use it for your car.
