Rotel RB-1582 MkII Stereo Power Amplifier Silver

Description Rotel RB-1582 MkII Stereo Power Amplifier Silver 200W per channel and monoblock layout with star grounding The Rotel RB-1582 MkII is the reference stereo power amplifier in Rotel's Music Systems range, delivering 200W per channel into 8 ohms and 323W into 4 ohms in Class A/B. It is the natural companion to the RC-1590 MkII preamplifier, and is the same power section that Rotel brought to the RA-1592 integrated amplifier. Internal construction adopts a monoblock layout for both channels (after the toroidal transformer), with all ground connections terminated in star configuration on a dedicated copper plate to ensure the lowest possible noise floor. The output stage is a fully discrete design with 10 high-current bipolar transistors per channel, selected to ensure reproduction accuracy with any loudspeaker, including the most challenging low-impedance configurations. Toroidal transformer and 60.000µF slit-foil capacitors At the heart of the power supply is an extraordinarily large toroidal transformer, paired with a total of 60.000µF of capacitance stored in British-made slit-foil capacitors. These capacitors, thanks to their thin-film geometry, charge and discharge extremely rapidly, ensuring a stable and immediate current supply even during the most intense orchestral crescendos or repeated kick drum strikes. Idle power consumption is 60W, indicating a power supply that's constantly ready to respond to the most sudden dynamic demands. Maximum power consumption at full power is 550W, with a BTU rating of 1104 BTU/h. Balanced XLR and unbalanced RCA inputs The rear panel offers a choice of balanced XLR or unbalanced RCA inputs for each channel. The XLR input has a 100kΩ impedance and a sensitivity of 3,0V, ideal for direct connection to the RC-1590 MkII preamplifier using balanced cables to eliminate common-mode noise. The RCA input has a 12kΩ impedance and a sensitivity of 1,9V. The rear panel features four pairs of color-coded speaker binding posts, two per channel, that accept bare wire, cable lugs, and dual banana plugs (excluding European versions). A 12V trigger allows for remote on/off control in coordination with other system components. Performance and Balanced Design Concept The signal-to-noise ratio is 116 dB (IHF A-weighting), total harmonic distortion is less than 0,03% across the entire audio frequency range, and the damping factor reaches 800 into 8 ohms—an exceptional value that ensures excellent control over the speakers even in the most dynamic situations. The frequency response extends from 10Hz to 100kHz with a deviation of ±0,5 dB. Rack mounting ears (3U) are included, making the RB-1582 MkII also suitable for installation in dedicated racks for high-end hi-fi and home theater systems. Why choose the Rotel RB-1582 MkII?
