An Expert Mode allows you to group channels and achieve perfect stereo processing, giving you a seamless, immersive audio experience.

It's also incredibly user-friendly, with Bluetooth 5.0 compatibility that allows for high-quality audio streaming and programming via an Android app. And perhaps best of all, this DSP engine is unbeatable at the price.
