Store Demo Levinson No. 585.

Nº585

The foundation of
the No585 is its fully discrete, mirror-imaged, dual-monaural analog
circuitry featuring individual signal switching relays for each of its
four stereo inputs: one XLR and three RCA. Volume controls use discrete
15-bit R-2R ladders and low-noise analog switches for the widest
possible bandwidth and maximum signal integrity. The fully-differential
Class AB power stage includes an oversized 900VA toroidal transformer
with individual secondary windings for the left and right channels. Each
elegantly simple amplifier channel utilizes twelve output transistors
and multiple smaller local capacitors that allow them to be placed
physically closer to the amplifiers for greater transient response when
power is needed immediately. This robust architecture results in a
conservative power rating of 200W per channel with stability into 2
ohms. System integration and expansion are possible using the stereo RCA
preouts which can operate full-range or with an included switchable,
second-order, 80Hz crossover filter allowing for seamless integration
into 2.1-channel systems with powered subwoofers.
