523 dual-monaural
preamplifier. Combining Mark Levinson’s unsurpassed analog
performance with flexible system configuration and advanced
digital and phono capabilities, these preamplifiers push the
reproduction of source material to new levels of realism.
Architecture
The foundation of these preamplifiers is their proprietary Mark
Levinson Pure Path discrete, direct-coupled, fully balanced,
dual-monaural signal path with discrete, balanced R-2R ladder
volume controls. They feature individual signal switching relays
for each of their stereo inputs: two balanced (XLR) and three
single-ended (RCA), plus phono; and six additional digital
inputs on the N
0
526. Volume controls use discrete 15-bit R-2R
ladders and low-noise analog switches for the widest possible
bandwidth and maximum signal integrity. System integration
and expansion are possible using the outputs, which can
operate full-range or with a switchable fourth-order, 80Hz filter
allowing for seamless integration into systems with powered
subwoofers.
Audio Chassis
Building upon this superb analog platform, the N
0
526 adds
equally outstanding digital audio capability. The Mark Levinson
Precision Link D/A converter with nine individual power
supplies, 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 at up to 192kHz, 32-bit resolution. For
low-resolution audio formats, proprietary HARMAN Clari-Fi®
music restoration technology reconstructs information and
bandwidth lost in compressed file formats. 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 preamplifiers utilizes modular architecture
to isolate critical low-level analog and digital circuitry from the
power supplies. The 6000-series extruded aluminum and steel
chassis features internal heatsinks and Mark Levinson’s iconic
appearance of black with silver trim.

INSTALLATION CONSIDERATIONS
UNPACKING
When unpacking your preamplifier:
• Save all packing materials in case you need to ship your
preamp in the future.
• Inspect your preamp for signs of damage during shipment. If
you discover damage, contact your authorized Mark Levinson
dealer for assistance in making appropriate claims.
• Please register your preamplifier within 15 days of purchase
at marklevinson.com.
• Retain your original, dated sales receipt as proof of warranty
coverage.
• Remove the accessory box from the shipping carton. Make
sure that all of the items listed below are included. If any are
missing, contact your authorized Mark Levinson dealer.
o IEC power cord (terminated according to the region to
which the unit is shipped)
o Remote control with preinstalled batteries
o Phillips screwdriver (for replacing remote batteries)
o Pair white gloves (for use during unpacking and initial
setup)
o Documentation
PLACEMENT AND VENTILATION
• Install the preamplifier on a shelf with several inches of
clearance above it to ensure proper ventilation. Do NOT
install the preamplifier inside of an enclosed cabinet or rack.
• Ensure that you install the preamplifier on a solid, flat and
level surface.
• Install the preamplifier as close as possible to associated
audio components to keep interconnecting cables as short as
possible.
• Select a dry, well-ventilated location that is out of direct
sunlight.
• DO NOT expose the preamp to high temperatures, humidity,
steam, smoke, dampness, or excessive dust.
• DO NOT block chassis ventilation holes.
POWER REQUIREMENTS
The preamplifier is configured at the factory for 100, 115, or
230 VAC power operation at 50Hz or 60Hz. Before operating,
ensure that the power label on the rear panel near the AC input
connector indicates the correct operating voltage. A detachable
IEC power cable intended for use in the region where the unit is
sold is included.
Connection to an AC voltage other than that for which the
unit is intended can create a safety and fire hazard and may
damage the unit. If you have any questions about the voltage
requirements for your preamplifier or about the line voltage in
your area, contact your authorized Mark Levinson dealer before
plugging the unit into an AC power outlet.
WARNING! MAKE SURE all components in the audio
system are properly grounded. Do NOT defeat the
safety purpose of polarized or grounding-type plugs
with “ground-lifter” or “cheater” adapters. Doing so
may cause dangerous voltage to build up between
components, which may result in personal injuries and/
or product damage.
You should unplug the preamplifier from the AC wall outlet during
lightning storms and extended periods of non-use.
CAUTION: BEFORE moving the unit, make sure it is powered off
by removing the power cord from the AC power outlet and the
unit’s rear panel.
