Founded in 1972, the Mark Levinson® brand has become synonymous with extraordinary levels of audio performance and has a reputation in high-end audio design like no other. From that heritage comes perhaps the finest, most-accomplished integrated amplifier ever made: the No585. Combining Mark Levinson’s unsurpassed analog performance with advanced digital audio capability and flexible system configuration, the No585 pushes the reproduction of any source material to new levels of realism.
- Six digital and four analogue inputs including USB, optical, coaxial, AES/EBU XLR and RCA for ultimate flexibility
- Fully discrete, mirror-imaged, dual-monaural analogue input and output circuitry
- High-current, fully differential (balanced) Class A B power amplifier section; power rating of 200W per channel into 8Ω.
- Digital audio processing stage through ESS Sabre 32-bit D/A converter
- Media USB audio processor for asynchronous data transfer at up to 192kHz / 32-bit resolution.
- Stereo preamp/subwoofer output with a selectable 80Hz high-pass filter for use in a properly implemented 2.1-channel system
- Ethernet, RS-232, IR and 12V trigger ports
The foundation of the Mark Levinson 585 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.
