Know before you buy
Yes, the RMB-1587MKII is highly capable with difficult loads. It delivers 250 watts per channel into 4-ohm speakers with all seven channels driven, ensuring consistent performance even with power-hungry home theater setups.
The dual toroidal transformers provide a stable, high-current power supply that prevents the amplifier from struggling during complex, dynamic audio passages. This ensures that your speakers receive clean, consistent power without interference or voltage drops.
If your processor or preamplifier supports balanced outputs, XLR is the preferred choice as it helps reject noise over longer cable runs. For shorter distances or systems without balanced outputs, the RCA inputs provide excellent, high-fidelity performance.
While it is designed to handle the demands of a 7-channel home theater, its Class AB design and high signal-to-noise ratio make it an excellent choice for high-end music listening. It offers the refined, low-distortion sound quality required for critical stereo or multi-channel music playback.
The RMB-1587MKII is a substantial piece of equipment measuring 17 inches wide, 9.33 inches high, and 18 inches deep. Because it weighs nearly 83 pounds and requires proper ventilation for its Class AB circuitry, ensure your rack or shelf is sturdy and has ample clearance on all sides.
The Class AB design strikes a balance between the efficiency of Class D and the sonic purity of Class A. It minimizes crossover distortion while remaining more energy-efficient and cooler-running than a pure Class A amplifier, resulting in a detailed, dynamic, and natural sound signature.
