RMB 1085
Class D Amplifier
Description
Rotel’s Class D amplifiers are technological marvels utilizing the latest circuit advances to deliver critically acclaimed performance. The RMB-1085 is a case in point. A space saving, cool-running and remarkably efficient design, the RMB-1085 is a real powerhouse, with 5 by 100 watts per channel of audiophile quality power into 8 ohms, all channels driven, at vanishingly low distortion.
The RMB-1085 is the ideal amplifier for high quality medium to large home theaters. In an elegant package less than 3” high, it will fit where large conventional amplifiers won’t, and because it produces so little heat, it won’t compromise other components located in the same space. It’s sophisticated power supply and output stages are rock solid even with power fluctuations and complex speaker loads. The RMB-1085 can deliver plenty of power when a film soundtrack demands it—even those floor-shaking sonic booms so prevalent in action movies. Yet, it is also superbly adept at revealing the smallest sonic details found in background audio effects. And like every Rotel amplifier, it excels at music playback.
