As with all Rotel products, this performance level
begins with a power supply based on Rotel-designed
and -“manufactured dual toroidal transformers. In addition
to providing proper voltages and current to subsequent
rectifiers, regulators, and capacitors, these transformers
also serve as a critical first stage of filtration for incoming
AC power. And the toroid shape itself tightly focuses stray
emissions to avoid their potentially negative impact on
sound quality.
Also in evidence is the Slit-Foil capacitor, an improved
variant of a conventional storage device. The Slit-
Foil is named after the many precise cuts made in the
aluminum conductors. These cuts or slits minimize
the eddy currents that reduce a conventional capacitors
ability to store and supply energy efficiently. The power
supply of RMB-1585s output section benefits from eight
British-made BHC Slit Foil caps, each with a capacity of
15,000 µF. And each channel uses six individual power
transistors to ensure stable power delivery to all speakers
The RMB-1585, Rotels new flagship theater amplifier,
provides both the massive power and sonic sophistication
required by the finest home theater systems.
With five channels, each capable of producing 200
continuous watts each into 8 ohm loads (a full kilowatt
of output power!), the RMB-1585 masters any A/V
system regardless of speaker load or room size.
But it isnt just pure output power that distinguishes
the RMB-1585. Its the ability to reproduce both the
dynamics of a Hollywood blockbuster and the musical
nuances of acoustic instruments that sets it apart.
Where does this balance come from? Its a direct
result of Rotels celebrated Balanced Design Concept
in which circuit topology and parts selection meld in
the pursuit of sonic excellence.

in the system even under the most demanding conditions.
Dual fans provide more-than-adequate airflow for
proper thermal dissipation.
These and other high quality components were carefully
chosen for their significant contribution to better sound
quality and then tuned to each other for even further
aural improvements.
The RMB-1585 makes system connection easy with
both single-ended inputs via RCA jacks or balanced
connections via three-pin XLR connectors.
In summary, you could describe the RMB-1585 as
a brute that provides a full kilowatt of power. Or you
might regard it as an exacting conveyer of the most subtle
aspects of music or a movie soundtrack. In either case,
youd be correct. Youd also be correct if you simply
said that the RMB-1585 is the win-win answer for
everyone seeking authoritative yet nuanced control
of the speaker array of your choice.
