Yksityiskohdat
Rotel RB-1590 on 40Kg painava järkälepääte. Kahdella erittäin järeällä toroidimuuntajalla varustettu pääteaste tuottaa 350w 8 Ohmin kuormaan ja tuplaa tehonsa joka askeleella...700w @ 4 Ohm....1400w @ 2 Ohm...2800w @ 1 Ohm... eli virta ei lopu ikinä, ainakaan vahvistimesta. Jos haluat päätteen joka ajaa mitävaan herkkyydestä ja vaihekulmasta riippumatta, niin tämä on valintasi.
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. Power - refined, detailed, and plenty of it. Rotel’s 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, 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 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.
