To perform at their best, speakers need clean power. Adding one or more high-quality amplifiers will go a long way in improving the performance of your system. OSD Audio offers a complete line of multi & 2-channels amps with various features and price points. Ideal for music systems, distributed audio, outdoor audio, or as a dedicated power amp for home theaters, our 2-channel line includes small table top units for powering a simple pair of speakers to high current amps such as our AMP300. The line also includes compact subwoofer amps with built-in crossover networks designed to be used with passive subwoofers.
