Experience the vibrancy of our home sound system. A great sound system relies on a great amplifier–theyre an integral element to a full soundscape. Create a multi-room audio environment, build a home theater, or expand your system to the outdoors. Our Versatility (D) Digital Amplifier AD508 has 8 channels rated at a power output of 65 watts into 8 ohms. It has a power output of 100 watts per channel into 4 ohms. 200 watts are x4 bridged to a mono channel at 8 ohms.
