Power - refined, detailed, and plenty of it. Rotels new
Class AB stereo power amplifier is rated at 350 watts
per channel into 8 ohms both channels driven. That
is a lot of power, but larger listening rooms or less
sensitive loudspeaker designs require it to bring out the best possible performance and attain realistic audio dynamics.
The impressive capabilities of this amplifier begin
with a solid foundation consisting of twin, massive
toroidal transformers custom made by Rotel. These
transformers are just part of a rock-solid power supply
that includes eight special British made BHC capacitors,
known for their low loss and quick response times.
These components will continue to supply all of the
voltage and current requirements needed, even under
the most difficult load conditions. But power unrefined has never been a Rotel design
goal. Every aspect of circuit design has been carefully
considered and each component has been rigorously
selected after extensive listening sessions. The circuit
topography has been laid out in a true monoblock
design ensuring maximum signal separation and
improved stereo imaging.
Features include: XLR Balanced and RCA input
connections, two pair of 5-way speaker binding posts, 12-volt trigger control, thermal protection circuitry, over-
current, over-voltage protection circuitry, dual staged
power on relay to reduce surge current and extend
longevity, and a detachable IEC power cord all in
a 5 U chassis with included rack ears.
The RB-1590 has been designed for the most
discerning audio enthusiast and will provide the
highest levels of audio performance.
