The sound quality of my home theater system has never been better since I got the Problue DY-09 Din Crossover Equalizer. The bass is deeper and the treble is clearer. I just wish it came with a more durable cable.

Can someone please explain how to adjust the crossover frequency setting? The manual is useless and the online tutorials I’ve found are all about different settings.

Why does it not come with a built-in test microphone? It’s annoying to have to find a separate mic to test the settings. A more user-friendly design would be nice too.
