【AD-8A｜8ch DSP amplifier with built-in HD player】

The AD-8A is for those who want to fine-tune the sound of their factory audio a bit more, or for those who feel that simply replacing the speakers isn’t enough to bring the sound together the way they want.

This is a high-end DSP amplifier supporting 8ch, with an HD PLAYER built in, and it supports playback of 192kHz/24bit audio sources. By adjusting the sound to suit the limited space inside the vehicle, you can enjoy your existing music in a balance that’s more to your liking.

Using the included controller, you can perform operations such as selecting folders and tracks, playing, stopping, and skipping tracks. Since you can search by folder name, artist name, album name, and title, it’s easy to find the music you want even when you have a large number of tracks, and it’s designed with usability in mind while driving.

Inside, it features two 32-bit audio signal processors, each operating at a 456MHz clock. With a wide range of sound adjustment, it’s a configuration that’s also easy to match with systems combining front speakers and subwoofers.

In addition, the DA/AD converters are modular, designed to support future upgrades. I think it’s a DSP amplifier that’s easy to consider for people who want to use it for a long time and revisit the direction of their sound as their system evolves.

However, with a DSP amplifier, simply installing the unit doesn’t determine the sound. The final result changes depending on factors including how it’s connected to the factory audio, how it’s combined with speakers and subwoofers, installation in the vehicle, wiring work, and the final adjustments.

At LOGON, we work with you to determine whether a configuration that uses the AD-8A makes sense, while confirming your vehicle model, your current system, the music you usually listen to, and your preferences for volume. Even if you’re unhappy with your current sound but don’t know where to start, please feel free to consult us first.
