Mark Levinson
DO allow at least 6 inches (15cm) of clearance behind the amplifier
so that the power cord and cables have space to bend without
becoming crimped or strained.
DO NOT place the amplifier chassis on a thick rug or carpet or
cover the amplifier 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 airflow through the amplifier.
DO NOT place the amplifier chassis near low-level components.
The power amplifier is capable of producing large output currents
and hence significant magnetic fields, which can induce noise in
sensitive components.
DO NOT expose the power amplifier to high temperatures,
humidity, steam, smoke, dampness, or excessive dust. Avoid
installing near radiators and other heat-producing appliances.
Warning!
MAKE SURE all components are properly grounded. Do not

power amplifier is capable of using. Contact a local, licensed
electrician for further information.
Operating States
The Nº500H series power amplifier 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. AC power is only
connected to the low-voltage power supply, so all nonaudio
functions, such as ML Net and triggers, are active.
5
•
On – the amplifier is fully powered and all outputs are active.
The amplifier should be unplugged during lightning storms and
extended periods of nonuse as a precaution against potentially
damaging power surges through the line.
Caution!
BEFORE moving the power amplifier, make sure it is powered
off with the Power button. Then make sure the power cord is
disconnected from the rear panel connector and the electrical
outlet.

The Nº531H, 532H and 533H utilize custom-made, gold-plated,
high-current loudspeaker binding posts, two for each output
channel. The Nº535H uses different high-current binding posts
due to space constraints. The positive binding posts, labeled +
(positive), are red; the negative binding posts are black and are
labeled – (negative).
Loudspeaker Binding
Posts
Note
Ensure when connecting the loudspeaker that at least one positive and
one negative binding post is used. There is NO ground reference.
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.

Nº500H Series Power Amplifier
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.
Caution!
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
The rear panel of the amplifier has two trigger connectors – one
input and one output. The trigger input can receive a 3-12V
DC signal from a connected component. The trigger output
passes through the trigger input signal, enabling a daisy-chain of
amplifiers to be controlled by a single trigger signal.
The triggers enable the power amplifier 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
amplifiers in the same manner.
9
Receiving a trigger signal causes the amplifier to change its power
state. If the amplifier is powered on, then 0V on the trigger signal
puts the amplifier into Standby or mode. Conversely, an amplifier
in Standby mode is powered on when 3-12VDC is received on the
trigger input.
Ethernet Port
The Ethernet port is a standard 10Base-T connection for use with
external control and networking. The Nº500H series supports
connection to a router or network, and to a PC-compatible
computer.
This connection is designed for use with proprietary Mark Levinson
external controllers, such as ML Net, or can provide serial port
control. For a list of the serial commands available, refer to the
separate document, No. 5 series Power Amplifier Serial Protocol
Definitions.
AC Input
Caution!
Provides AC power to the amplifier 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.

Network Setup
The Nº500H series power amplifier supports a network connection
through the Ethernet port. The Nº500H series can connect to a
network through use of a router or directly to a computer.
The Nº500H series can be:
1. Connected to a router with DHCP active – We highly
recommend using this option. Since the DHCP (Dynamic Host
Configuration Protocol) automatically assigns the IP (Internet
Protocol) addresses, setup is much simpler.
2. Connected to a router with DHCP not active – This method
requires more advanced networking knowledge to set up
because it uses fixed static IP addressing.
3. Connected directly to a computer with no router – We
recommend only using this option when a router is not
available. This method requires more advanced networking
knowledge to set up because it uses fixed static IP addressing
and a special network crossover cable.
This section provides general instructions for all three methods.

Mark Levinson
ML Net
The ML Net protocol allows you to control two or more Mark
Levinson products simultaneously via the Ethernet port.
Since ML Net operates through the use of a router and the Ethernet
connection, all devices must have networking capability. Refer to
the previous section of this manual, “Network Setup,” to set up the
Nº500H series for network operation.
Note
ML Net uses a single “Master” device to control specific functions
of other ML Net-capable Mark Levinson products. An ML Net
system can only have one Master device; all other devices in the
system become “Slaves”. Slave devices receive and respond to the
commands of the master device.
Masters and Slaves
The Nº500H series power amplifier is always a slave device. A
separate master device must be used in conjunction with the
Nº500H series amplifier.
As a slave device, the amplifier responds to the following ML Net
commands sent from the master device:
18
•
Status Reporting – status conditions of the Nº500H
series slave(s) are reported to the master device; status
includes Temperature, Session Time, Total On Time, and
Fault Reporting.
•
•
Standby State – the master device controls the Standby state
of the amplifier.
Synchronized LEDs – the Standby LEDS of the master device
and all assigned slave devices blink in unison.
After configuring each device on the network, connect all of the
devices together. Ensure that all components are powered off or in
Standby mode before connecting to the Ethernet ports.
Connecting the
Devices
Each device must be connected to the same network and use the
same subnet. Refer to the “Network Setup” section for instructions
on how to connect the Nº500H series to the network.
If more devices are desired than the router can handle, connect the
additional devices first to a switch, then connect the uplink of the
switch to a normal port on the router.

Discovering Slaves
Status Reporting
Before the master device can control any slave device, the slave
devices must be “discovered” and assigned to the master device.
Refer to the Owner’s Manual of the designated master device for
further information about discovering and assigning slave devices.
19
The Nº500H series slave(s) can report the following status
information to the master device:
•
•
•
Temperature – the current operating temperature of the
amplifier(s).
Session Time – the amount of time that the amplifier(s)
has been powered on.
Total On Time – the total amount of hours that the
amplifier(s) has been powered on since its manufacture.
If a slave device is inactive, unassigned, or assigned to a different
master, then status information is not available.
Fault Reporting
The Nº500H series slave(s) also reports fault information to the
master device. If a slave device is inactive, unassigned, or assigned
to a different master, then error reporting is not available. For more
information about possible fault conditions, refer to the
“Troubleshooting” section of the manual.

Incorrect operation is sometimes mistaken for malfunction. If
problems occur, use this section for troubleshooting information. If
problems persist, contact your authorized Mark Levinson dealer.
1. Examine the power cord to ensure that it is connected to both
the rear panel connector of the amplifier and an electrical
outlet.
No Power
2. Make sure the amplifier is powered on with the Power switch.
3. Make sure the amplifier is not in Standby mode. The front
panel LED should be at full brightness.
4. Examine the electrical circuit breaker to ensure that power
is being supplied to the electrical outlet to which the amplifier
is connected.
5. Verify that the voltage rating on the rear panel of the amplifier
matches the voltage rating of the electrical outlet. If the
voltages do not match, no power is sent to the outputs of
the amplifier.
1. Make sure that the source device is powered on, playing audio,
and set to the right output connector.
No Output
20
2. Examine cables to ensure a solid connection between the
amplifier and associated components.
3. Make sure the amplifier's output connectors are connected to
operational loudspeakers.
4. Ensure that the amplifier is not in a fault condition. When the
amplifier experiences a fault, the output is muted and the Status
LED on the front panel blinks in a rapid pattern, indicating:
LED Behavior
Description
Rapidly blinking
(on most of the time)
Indicates that a power-related fault has
occurred.
Rapidly blinking
(on half of the time)
Indicates that a signal-related fault* has
occurred.
Rapidly blinking
(off most of the time)
Indicates that a thermal-related fault has
occurred.
*Signal-related faults include significant DC offset at the output due to either DC in the input
signal or a failed component within the amplifier OR excessive current demands due to a
short-circuited loudspeaker wire.
You must assign the slave from the master device. Verify that the
slave you want to assign is listed in the master device list and
check its current state. For further explanations on assigning slave
devices, refer to the owner’s manual of the master device.

Mark Levinson
Fault Protection
The Nº500H series is designed to prevent damage to themselves
and associated components. These extensive features protect both
the critical circuitry of the amplifier itself and shield connected
loudspeakers from serious damage due to high-power levels.
Basic protections designed into the Nº500H series include fuses
on each amplifier channel to protect against excessive current
conditions, such as driving shorted outputs. Inrush limiting
prevents premature aging of the power supply components during
power-up; once the power supply has been charged, this feature
goes off-line until the amplifier is powered up again.
The Nº500H series actively monitors operating temperature, output
current demands and the presence of DC on the outputs. The
amplifier will shut down under any of these conditions and report
the fault via the front panel LED and over the Ethernet connection.
The amplifier must be shut down to clear the fault condition before
being powered back up.
22
ML Net Fault Conditions
The slave devices in an ML Net system can report fault conditions
to the master device. Fault condition reports are displayed on the
display of the master device when the fault occurs. Some faults
may cause the amplifier to enter Standby mode. Power-cycling the
amplifier clears the fault condition, providing the
fault condition no longer exists.
Some faults do not allow power to be reapplied to the amplifier until
the fault condition no longer exists to protect the amplifier from
damage.
Note
The fault conditions reported are:
•
•
•
•
Slave Device DC Offset – indicates that the Nº500H series
amplifier is experiencing a signal-related fault.
Slave Device Over Current – indicates that the Nº500H
series is experiencing an over-current condition.
Slave Device Over Temperature – indicates that the
Nº500H series amplifier is overheating.
Signal – indicates that the Nº500H series has experienced a
general signal fault.
