Multichannel Power Amplifier
RMB-1585

The RMB-1585, Rotel’s 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 isn’t just pure output power that distinguishes the
RMB-1585. It’s 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? It’s a direct result
of Rotel’s celebrated Balanced Design Concept in which circuit
topology and parts selection meld in the pursuit of sonic
excellence.
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 aer the
many precise cuts made in the aluminum conductors. These cuts
or “slits” minimize the eddy currents that reduce a conventional
capacitor’s ability to store and supply energy eiciently. The
power supply of RMB-1585’s 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 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, you’d be correct. You’d 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.
