RB-1552 MkII is built upon the same platform as the RB-1582 MkII with only a slightly smaller power output capability at 2 x 130 Watts. The RB-1552 MkII is a 130 Watt per channel class AB amplifier.

Notable features of the amplifier include independent left and right power rectification stages and decoupling. The layout is essentially a mono block design. Input options are balanced XLR or unbalanced RCA connectors.

RB-1582 Mk II

http://www.rotel.com/product/rb-1582-mkii
Rotel’s next largest stereo amplifier at 200 Watts per channel.

The RB-1582 MkII’s high-end performance begins with an extremely large toroidal transformer combined with a total of 60,000µF storage capacity in special “slit foil” capacitors to provide completely stable power to the output stage. Both left and right channel construction are laid out in a mono block design (after the toroidal transformer) and all grounding is terminated in a star pattern on a copper grounding plate to ensure low signal to noise. The output stage is a discrete design that consists of 10 high current bipolar transistors per channel. Input options consist of both balanced XLR and unbalanced RCA connectors.

RB-1590

http://www.rotel.com/product/rb-1590 
The RB-1590 is at the top of its class as a 2 x 350 Watts stereo amplifier with dual toroidal transformers and special slit foil capacitors.

Rotel’s new Class AB stereo power amplifier is rated at 350 Watts per channel into 8 ohms both channels driven.  The 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.

Features include: XLR Balanced and RCA input connections, two pair of 5-way speaker binding posts, 12-volt trigger control, thermal protection circuitry, overcurrent, 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 5U chassis.
