【HSA-400-31.opt｜4-Channel DSP Amplifier Adjustable via Smartphone】

For those who want to fine-tune the sound inside their car to better match their preferences—here is the 4-channel DSP amplifier “HSA-400-31.opt.”

the unit supports iOS/Android apps, allowing you to adjust how the sound “comes together” in the cabin using the dedicated app. One of the strengths of a DSP amplifier is that it lets you refine details that can’t be fully corrected by simply replacing speakers—such as the positioning of left/right sound and the balance among each speaker—so you can dial it in precisely according to your vehicle and system.

With a 4-channel configuration and a music output of 50W×4, it can be considered based on your vehicle’s specifications and the sound you’re aiming for—for example, if you want to pursue changes in sound while making the most of the factory audio, or if you want to build your system centered around the front speakers.

However, a DSP amplifier isn’t something that’s finished just by installing the main unit. The way it sounds will change depending on the input method, the combination with your speakers, how power and wiring are handled, and—finally—the ultimate tuning. At LOGON, we work with you to think through a reasonable configuration while confirming your vehicle model, your current system, the music you listen to often, and your sound preferences.

If you want to make the factory sound a bit easier to listen to, find that speaker replacement alone isn’t enough, or want to adjust the positioning of vocals and instruments in the cabin, please consider the HSA-400-31.opt and reach out to us for consultation. Choosing not just the product itself, but also based on compatibility with your entire vehicle system, is what leads to satisfaction after installation.
