The RB-1552MKII is a 120 watt per channel class
A/B amplifier. It is engineered to be powerful and
robust, yet able to extract every last nuance out
of even the most complex musical score.
Rotel engineering’s fanatical attention to detail
means the sum is greater than the parts, what we
call our Balanced Design Concept*. Each aspect
of design is carefully considered holistically to result
in maximum audio performance; from the selection
of an over-sized power supply featuring a highly
efficient, low magnetic field toroidal transformer
to multiple, high-current bipolar output transistors.
Circuit topology is planned, implemented, evaluated,
and adjusted to achieve optimum results. The
RB-1552MKII features independent left and right
power rectification stages and decoupling, and is
essentially a mono block design. Further evidence
of design over-spec is in the selection of premium
“slit-foil” capacitors, which provide plenty of reserve
energy for extremely dynamic audio passages and are
able to quickly replenish themselves due to the nature
of their unique design. Input options are balanced XLR
or unbalanced RCA connectors.
The RB-1552MKII stereo amplifier has been engineered
to provide high-resolution audio performance, yet it is
very affordable, as has been the tradition with Rotel
electronics for over 50 years.
