ROTEL RB1582 MKII (unpacking equipment)

Rotel’s second largest stereo amplifier offers massive power at 200 watts per channel, and easily powers the largest hi-fi systems. The RB-1582 MKII is capable of driving even large speaker systems with ease. It was developed with the aim of reproducing both the finest details and dynamic-rich impulses with great aplomb. This balancing act succeeds so excellently because both the basic circuit design and the selection of the optimal components were made with the greatest care.

The basis for the enormous performance of the Rotel RB-1582 MKII is the high-performance power supply, which is based on a generously dimensioned toroidal transformer in conjunction with special storage capacitors that provide no less than 60,000 °F of storage capacity. This ensures the outstanding dielectric strength of this powerhouse. The extremely short charge and discharge times of the BHC “slit-foil” capacitors allow for high signal fidelity even when sweeping crescendos or powerfuldrum kick impulses demand the highest performance from this power amp.

After the common toroidal transformer, the two power amplifier groups are quasi-monoblock design. The grounding is strictly star-shaped. The power amplifiers themselves are discrete; no less than ten individual transistors per channel take care of the current amplification. Inputs are either balanced XLR or unbalanced RCA jacks.

Loudspeakers with below-average efficiency or complex impedance characteristics place high demands on an amplifier in terms of output power and load stability. Large rooms also place enormous demands on an amplifier, since then only pure power counts when high sound pressures are required. And it is precisely for these applications that the Rotel RB-1582 MKII was designed.
