One Button is All You Need to Unleash the Power behind the Panel

Call it what you will—prodigious, colossal, mega, and at 112 pounds (51 kg), “behemoth” is likely to come into the conversation—we've simply dubbed it the RDA-7.1. If you've found yourself at a loss for more words, let us finish the description for you. Integra Research has teamed up with Balanced Audio Technology to go beyond the definition of what a power amplifier should and can do. A low negative feedback design yields optimal signal-to-noise performance and dynamic contrasts superior to what is commonly found on the market. Balanced XLR inputs give you authoritative frequency response, dynamic range and stability for cable runs longer than the competition dare think about. 150 watts x 7 into 8 ohms, with all channels driven, can effortlessly handle virtually any speaker load or listening level, and, possibly to the neighbors' chagrin, fill any room in your house with earth-shattering audio. The finest audiophile-grade parts are guaranteed by the ultimate mark of quality in the home theater environment—THX Ultra2 certification. So press the button. Provide the power to drive the most demanding of speaker loads. Understand that “awesome” doesn't begin to describe the sensation you're set to experience.
