RMB-1585 MKII Power Amplifier
Designed to impress, the RMB-1585MKII delivers unparalleled performance with 5-channels of classic proprietary Rotel Class AB amplification. The amplifier effortlessly delivers 210 Watts per channel into 8 ohms and an impressive 340 Watts per channel at 4 ohms, with all channels driven. When driving 2 channels, the amplifier excels even further, reaching an astonishing 440 Watts per channel, ensuring optimal power distribution even under extreme loading conditions.
Utilizing dual in-house manufactured oversized toroidal transformers and 8 high-efficiency bulk storage capacitors totaling 120,000uF, the RMB-1585MKII produces controlled, deep bass while maintaining finesse and detail in the midrange and high frequencies.
The amplifier incorporates upgrades and improvements in both the power supply and amplifier gain stage circuits, leveraging Rotel's advanced MKII design architecture enhancing detail and precision.
This intuitive amplifier features a rear panel switch conveniently allowing the amplifier to be configured as a 3-Channel amplifier supporting Bi-Amp mode of Channels 1+2 and 4+5. When Bi-Amp is enabled Channels 1+2 automatically utilize source input #1 and Channels 4+5 automatically utilize source input #5 allowing individual, isolated amplifiers routed to the speakers HF and LF drivers. This unique configuration ensures precise signal path routing, effectively separating the High Frequency (HF) and Low Frequency (LF) drivers. The resulting audio enhances resolution and provides higher drive power to the loudspeakers.
The RMB-1585MKII offers versatile support for XLR Balanced and RCA inputs, with auto-switching to the connected inputs. It also includes a 12 V trigger input and output for simplified power control. Equipped with four ultra-low noise, variable speed cooling fans that are CPU thermostat-controlled, this amplifier ensures optimal cooling performance.
