"" The robust bass & resonance that parties demand have been further strengthened by the unique Bass Reflex System. Unique port technology pushes sounds forward without losing the resonance of sounds generated from behind the woofer unit. This further amplifies the bass to produce extremely powerful sound. With the wide versatility of the Local Preset Equalizer, you can maximize your enjoyment of different music genres, such as Rock, Karaoke, & more. Football mode also makes it more fun to watch TV. You can select the sound to match whatever it is you are enjoying. Inheriting the MAX series' concept, the MAX3500 gives an impression of power at a glance & presents a more refined & contemporary appearance. The material features two distinctly different surface textures of matte & gloss, creating an elegant contrast that befits the quality & power of the MAX3500. The slim center unit allows more flexible setup in the room, for example, in the rack below the TV. The new refined & powerful MAX3500 enhances any room interior. In pursuit of the ideal party atmosphere, MAX has greatly advanced its lighting performance. The illumination that has been newly added to the main unit rotates to produce a dazzling effect for both the room & the dancers. It combines with the speaker unit illumination to raise the mood of the party. The main unit has two mic jacks so you can plug in two microphones for duets with family & friends. Various functions make it easier to sing, like Vocal Cancel, Key Control, Tempo Control*, BGM Level Control, & Mic EQ. & the Echo function produces great karaoke singing effects.* Tempo Control can be used with CD, USB (Universal Serial Bus) & Internal Memory.
