    Home Theater Amplifiers


    OSD Home Theater Amplifiers Crafted for Cinematic Clarity

    OSD Audio has a long history in manufacturing home theater amplifiers. More than 10 years ago we introduced the A5000, astonishing the world with its audiophile sound quality at an affordable price.

    Since then, we have innovated, expanded and improved our lineup of amplifiers designed for home theater use. We now have six models, with a seventh coming shortly, that offer everything from bridged two channels, all the way to 11-channel designs. Our power ratings go from 100 watts to 400 watts per channel, with all channels driven. Our distortion levels and signal-to-noise ratios are all comfortably in the range of inaudibility. Whatever your home theater amplification needs are, we have you covered.
