The pursuit of perfect amplication is a well-known theme in high-end audio.
New technologies present new approaches, while looking to the past provides
inspiration for the future. It was in that spirit that the Mark Levinson N

536
Monaural Amplier was developed: an amplier advised by the traditions and
art of classic amplier design, and infused with modern technology. A fully
discrete, differential, direct-coupled signal path; a highly linear, low-feedback
design; and voltage gain and drive stages operating in class A, are joined by
the modern system integration capabilities provided by Ethernet, RS-232, and
USB for monitoring and network control.

The N
536’s core design principles are its very high open-loop linearity and
extremely high bias current. Because the amplier circuitry was designed
to have such intrinsically high performance, it requires very little feedback
to achieve impeccably low distortion and enormously wide bandwidth.
Employing unusually high bias current enables superb linearity with wide
bandwidth: nearly immune to the effects of parasitic capacitances, the N

is able to change voltage with unreserved agility. These design principles
create the hallmarks of Mark Levinson amplication: effortlessness, openness,
and unadulterated smoothness throughout the entire frequency range,
regardless of load or listening level.
Mark Levinson takes pride in both the art and science of engineering. To
that end, components are selected based not only on their technical merits,
but also on their sonic capabilities. The Mark Levinson N

536 also features a custom-designed, low noise
toroidal transformer, rated for 1,800VA total continuous power with separate
secondary windings for each output stage. The output stage and power
supply components are over-specied to offer unsurpassed performance and
reliability. The input stage of the N

536 contains two matched-pair, low-
noise, high-gain, dual JFET input transistors, which in turn are connected
in a double cascode conguration to bipolar transistors; the combination
of devices offers inherently low distortion and wide bandwidth, as well as
the ability to effortlessly swing large signal voltages. This circuit operates in
a fully balanced, differential conguration and uses discrete TO-126 bipolar
pre-driver transistors to accurately drive the massive output stages.

Unpacking
Caution!
Placement and
Ventilation
DO save all packing materials for possible future shipping needs.
DO inspect the amplier for signs of damage during shipment. If damage is
discovered, contact your authorized Mark Levinson dealer for assistance in
making appropriate claims.
DO locate and remove the accessory bag from the carton. Make sure it
contains all of the items listed in the “What’s in the Box” table on the
previous page. If not, contact your authorized Mark Levinson dealer.
DO NOT attempt to lift or move the power amplifier without
adequate assistance. The shipping weight of the amplifier exceeds
what a single person should lift alone. To avoid injury or damage to
the unit, at least two people are required to lift or move the amplifier.
Knit white gloves with special gripping surfaces on the palms and
fingers are included with the amplifier. Wear these gloves when
lifting or moving the amplifier.
DO install the power amplier on its own shelf for proper ventilation.
DO install the amplier chassis on a solid, at, level surface.
DO install the power amplier close to associated components to keep
interconnecting cables as short as possible.
DO select a dry, well-ventilated location out of direct sunlight.
DO allow at least 3 to 4 inches (8 to 10cm) of clearance above and on each
side of the amplier for proper heat dissipation.
DO allow at least 6 inches (15cm) of clearance behind the amplier so that
the power cord and cables have space to bend without becoming crimped
or strained.
DO NOT place the amplier chassis on a thick rug or carpet or cover the
amplier with a cloth, as this might prevent proper cooling.
DO NOT obstruct the ventilation holes on the top and bottom of the
chassis or reduce airow through the amplier.
DO NOT place the amplier chassis near low-level components.
The power amplier is capable of producing large output currents and
hence signicant magnetic elds, which can induce noise in sensitive
components.
DO NOT expose the power amplier to high temperatures, humidity,
steam, smoke, dampness, or excessive dust. Avoid installing near radiators
and other heat-producing appliances.
Warning!
4
MAKE SURE all components 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 can result in
personal injuries and/or product damage.
Nº536 Series Power Amplifier
Power Requirements
The amplier is congured at the factory for 100, 120, or 230 VAC power
operation at 50Hz or 60Hz. Before operating the amplier, ensure that the
power label on the rear panel near the AC input connector indicates the
correct operating voltage.
Caution!
Caution!
DO NOT attempt to adjust the operating voltage. Consult a
Mark Levinson dealer if the operating voltage is incorrect or must be
changed for relocation purposes.
Different operating voltages may require the use of different power
cords and/or attachment plugs. Contact a Mark Levinson dealer for
additional assistance.
This amplier is capable of passing remarkable sound at exceptional power
levels. Depending on listening habits, loudspeaker demands, and the number
of power ampliers present in the system, it is possible that the electrical
service may become the limiting performance factor of your system.
If this case occurs, consider installing a dedicated AC circuit for the system.
Contact a licensed electrician for assistance. If more than one AC circuit is
providing power to the system, contact a licensed electrician to ensure that
all components are operating with the same solid, low-impedance ground
reference.
Building regulations and electrical codes differ from location
to location, making it impossible to anticipate the requirements
of amplifier high-current AC circuits. Contact a local, licensed
electrician for further information.

The audio outputs of this power amplier are considered Class 2 (CL2)
circuits in North America. This means the wire connected between this
amplier and the speaker(s) shall be rated at minimum Class 2 (CL2) and
shall be installed according to the U.S. National Electrical Code (NEC)
Article 725 or Canadian Electrical Code (CEC) Section 16.

One balanced and one single-ended (unbalanced) connector is available for
each audio channel input.
Accepts a signal from a preamplier with balanced outputs via the XLR
connector. A small toggle switch selects either the balanced (XLR) or single-
ended (RCA) input connector. Make sure the toggle switch is set to the
position closest to the XLR connector.
The pin assignments are consistent with the standards adopted by the Audio
Engineering Society. Refer to the operating manual of your preamplier
to ensure that the pin assignments of its balanced output connectors
correspond to the No-536. If not, wire the cables so that the appropriate
output pin connects to the equivalent input pin.

Note
The RCA connector accepts unbalanced or single-ended signal from
preampliers with RCA outputs. If your preamplier has both RCA and
XLR outputs, use the XLR output. Set the toggle switch to the position
closest to the RCA connector.
The No-536 amplier utilizes custom-made, gold-plated, high-current
loudspeaker binding posts. The positive binding posts, labeled + (positive),
are red; the negative binding posts are black and are labeled – (negative).
Two of each binding post are present on the No-536, enabling bi-wiring for
compatible loudspeakers. If your loudspeakers support bi-wiring, connect
both red (positive) terminals to the red terminals on the loudspeaker, and
connect both black (negative) terminals to the black terminals on the
loudspeaker.
If your loudspeakers do not support bi-wiring or you prefer not to employ
this connection conguration, simply connect one of the positive and one
of the negative terminals to the respective loudspeaker terminals. There is
no additional conguration needed to disable bi-wiring output capability.
Banana plugs can also be used to connect the speaker cables to the
loudspeaker binding posts. Banana plugs are not available on the
230 VAC model.
Ensure when connecting the loudspeaker that at least one positive and one
negative binding post is used. There is NO ground reference.
Caution!
Caution!
Be careful to not short the positive and negative outputs together.
Do not short the positive or negative outputs to chassis or any other
safety ground. The amplifier must be powered off during installation
and whenever input and/or output cables are being connected. This
is a balanced amplifier and all binding posts are active at all times.
Do not attempt to connect any binding posts to ground.
DO NOT OVERTIGHTEN the binding posts. The innovative design
of these binding posts provides more leverage; hence, high-contact,
tight pressure connections are achieved when finger-tightened.
DO NOT FORCE the binding post “wings” over a bent or oversized
connector. Doing so may damage the binding post.

Trigger Input and
Output
AC input
Caution!
Network Connection
The rear panel of the amplier has two trigger connectors – one input
and one output. The trigger input can receive a 12V DC signal from a
connected component. The trigger output passes through the trigger input
signal, enabling a daisy chain of ampliers to be controlled by a single
trigger signal.
The triggers enable the power amplier to be automatically powered on
or put into Standby mode by the state of other devices in the system. The
trigger output can also affect other power ampliers in the same manner.
Receiving a trigger signal causes the amplier to change its power state.
If the amplier is powered on, then 0V on the trigger signal puts the
amplier into Standby mode. Conversely, an amplier in Standby mode is
powered on when 12VDC is received on the trigger input.
Provides AC power to the amplier when the supplied power cord is connected
from the AC Input connector on the rear panel to an electrical outlet.
Before operating the amplifier, verify that the voltage label near the
AC input connector indicates an operating voltage compatible with
the voltage level of the electrical outlet you intend to use.
The No-536 connects to your network through an Ethernet cable. When
connected, the No-536’s Ethernet connector’s status LED ashes.
RS-232 Connector
Operating States
This connector is provided to enable conguration and control of the
amplier from a personal computer equipped with a serial port. Contact
your dealer or installer for information on how to use this feature.
Operation
The amplier is designed for continuous operation and has three
operating states:
• Off – AC power is disconnected using the rear-panel Power switch or by
removing the power cord from the rear panel.
• Standby – This is an energy-saving mode with three options.
• Green (Factory Default): This is the lowest-power standby mode
for maximum energy savings. You will experience a longer power-up
process from standby. Ethernet and RS-232 are disabled in this mode.
• Power Save: Moderate energy-saving standby mode, which enables
wake-up via RS-232 or Ethernet.
• Normal: This mode mutes audio outputs, but keeps all of its control
and audio circuits powered. This mode provides the least amount of
power conservation but allows the No-536’s audio circuits to remain
warmed up to deliver optimal performance at all times.
• On – The amplier is fully powered and all outputs are active.
Caution!
