585.5 INTEGRATED AMPLIFIER / OWNER’S MANUAL
ENGLISH
Thank you for purchasing the N
0
585 integrated amplifier.
Combining Mark Levinson’s unsurpassed analog performance
with advanced digital audio capability and flexible system
configuration, the N
0
585 pushes the reproduction of any source
material to new levels of realism.
Architecture
The foundation of the N
0
585 is its fully-discrete, mirror-imaged,
dual-monaural analog circuitry featuring individual signal
switching relays for each of its four stereo inputs: one balanced
(XLR) and three single-ended (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 A/B 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, which allows 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. 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.
Audio Chassis
Building upon this superb analog platform, the N
0
585 adds
equally outstanding digital audio capability. An ESS Sabre 32-
bit D/A converter with proprietary jitter elimination circuitry and
fully-balanced, discrete I/V circuitry forms the heart of the digital
audio processing stage. Six digital audio inputs are provided
including one AES/EBU, two coaxial and two optical plus a
USB audio processor capable of asynchronous data transfer
of high resolution DSD and PCM files at up to 192kHz/32 bits
resolution. For low-resolution audio formats, proprietary Clari-
Fi™ signal processing reconstructs information and bandwidth
lost in compressed file formats restoring them to higher fidelity.
System integration and communication ports include Ethernet,
USB, RS-232, IR input, and 12V trigger input and output. A
system IR remote control is included.
Construction
The chassis of the N
0
585 utilizes card-cage architecture to
isolate critical low-level analog and digital circuitry from the
power supplies and amplifier modules. The steel and aluminum
construction features internal amplifier heatsinks and Mark
Levinson’s iconic black and silver anodized aluminum front
panel with its intuitive twin-knob control system and unique red
display.
