Rotel RB-1582 MKII

Loudspeakers with below-average efficiency or complex impedance curves place high demands on an amplifier in terms of output power and load stability. Even large rooms make enormous demands on an amplifier, as sheer power is what counts when high sound pressure levels are required. The Rotel RB-1582 MkII was created for these purposes. It combines extraordinary musicality, excellent reproduction of details and an enormous output power of a full 200 watts per channel into 8 ohms.

The Rotel RB-1582 MKII delivers enormous currents when required and drives even large speaker systems effortlessly. Like its sister, the Rotel RB-1552 MKII, the Rotel RB-1582 MkII was developed with the aim of reproducing both the finest details and the most dynamic impulses with great aplomb. This balancing act works so well because both the basic circuit design and the selection of the optimal components have been carried out with the greatest care.

The basis for the enormous performance of the Rotel RB-1582 MKII is the high-performance power supply unit with the lush toroidal transformer in connection with the four large storage capacitors, which provide no less than 60,000 æF storage capacity. This ensures an outstanding dielectric strength of this powerhouse. The extremely short charging and discharging times of the BHC 'Slit-Foil' capacitors enable a high level of signal fidelity even when sweeping crescendos or full drum-kick impulses demand the highest performance from this power amplifier.

After the common toroidal transformer, the two output stage groups are designed as a monoblock design. The mass routing is strictly star-shaped; Signal-to-noise ratios are therefore at an extremely high level. The output stages themselves are discreet; no less than ten individual transistors per channel take care of the current amplification. Either balanced XLR or unbalanced cinch sockets are used as inputs.
