【GZDSP 4-8XⅡ｜A DSP Processor That Refines the Sound of OEM Audio】

For those who want to add a bit more detailed tuning to the sound of OEM audio, or who want to adjust the sound to suit the vehicle after replacing the speakers, the GZDSP 4-8XⅡ is the right choice. This entry-level model is equipped with a wide range of functions needed to really dial in car audio—featuring 10-band × 8 parametric EQ, as well as time delay, phase control, an active crossover, and more.

Simply replacing the speakers may leave tonal imbalances caused by the vehicle’s interior shape and mounting positions. With the GZDSP 4-8XⅡ, you can fine-tune things like the frequency-by-frequency balance and the timing of when the left and right sounds reach you—then finish the vocal placement and the cohesion of the soundstage to match the cabin.

It also supports high-level input, making it easy to incorporate into setups where you keep the OEM audio and aim to improve sound quality. It’s also well-suited for people who want to make the music they always listen to a little easier to enjoy, without significantly changing how the system is used day to day.

That said, a DSP doesn’t determine the sound by installation alone. Depending on the vehicle model, OEM system, and the combination with the speakers, the tuning requirements will vary. At LogOn, we confirm the vehicle condition and your preferences, then work with you to design a reasonable setup—handling everything from installation to sound tuning. If you’re wondering how much you can change the sound with a DSP, please consult us while looking at your current system first.
