Rotel RB1552 MKII Power Amp (Black)

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. 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.

Rotel RB1582 MKII Power Amp (Black)

The RB-1582 MKII ‘s stereo amplifier at 200 watts per channel provides the massive current to drive the very largest hi fi systems effortlessly. The RB-1582 MKII ‘s high-end performance begins with an extremely large toroidal transformer combined with a total of 60,000uF storage capacity in special “slit foil” capacitors to provide completely stable power to the output stage. Slit foil capacitors have the ability to charge and discharge extremely quickly, thereby ensuring signal fidelity during orchestral crescendos or repetitive kick-drum impacts, for example. 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.

Rotel'sClass A/B stereo power amplifier is a powerhouse rated at 350 watts per channelinto 8 ohms, both channels driven. Ideal for larger listening rooms and lesssensitive loudspeaker designs that require more power to bring out the bestpossible performance and attain realistic audio dynamics.

 

TheRB-1590’s impressive capabilities begin with a solid foundation consisting ofmassive twin toroidal transformers custom designed and built by Rotel. Thesetransformers are just part of a rock-solid power supply that includes eightspecial British made BHC capacitors, known for their low loss and quickresponse times, thereby improving high-energy signal transients and dynamicbass performance. These components will continue to supply all of the voltageand current requirements needed, even under the most difficult load conditions.

 

TheRB-1590 is not based on just raw power alone. Every aspect of its circuit design has been carefully considered andeach component has been selected after extensive and rigorously listeningsessions. Circuit topography has been laid out in a true mono-block designensuring maximum signal separation and better stereo imaging.

 

TheRB-1590 is for the discerning audio enthusiast and provides the highest levelsof performance.
