Introduction  
Thank you for purchasing the Mark Levinson® Nº512 CD/SACD  
player.  
The Nº512 CD/SACD player is designed for aural excellence.  
Incorporating the best of past Mark Levinson designs, the Nº512  
provides the highest standard of two-channel audio performance  
available, seamlessly supporting the playback of both SACD and  
PCM data types. From its classic industrial design to the thorough  
listening tests performed before release, the Nº512 meets the  
high-performance demands of Mark Levinson.  
Product Description  
The highlight of the Nº512 player is its high-end data conversion  
capabilities. Its internal design focuses on preserving signal integrity  
while preventing the introduction of noise and jitter. Digital and  
analog signal paths are individually powered using separate toroidal  
transformers. All signals are carefully hand routed to ensure  
maximum isolation and minimum crosstalk. The Analog output  
topology routes analog signals in balanced mode wherever possible.  
The analog audio printed circuit board is manufactured using high  
performance Nelco, a modern equivalent of Arlon with similar high  
bandwidth properties.  
2
Another important feature of the data conversion system is the  
handling of audio clocks. Since jitter and noise can cause  
inaccuracies during the data conversion process, a clean master  
clock provides improved digital-to-analog conversion with fewer  
time-based conversion errors. The No512 utilizes a custom Mark  
Levinson implementation of Direct Digital Synthesis to remove  
jitter on the audio master clock. The end result of this DDS  
technology is an extremely accurate and stable time reference  
producing superior performance and sound quality in all audio  
playback.  
All system functions can be performed from the backlit, metal  
remote control, which feels both substantial and elegant in your  
hand. Additional features, such as track programming and shuffle,  
are available via the remote control.  
For external controls, the No512 supports triggers, serial port  
control, and the ML Net protocol, which controls and synchronizes  
other Mark Levinson products through the use of an Ethernet port.

Installation Considerations  
The Nº512 CD/SACD player requires special care during installation  
to ensure optimal performance. Pay particular attention to  
instructions included in this section and to precautions included  
throughout this owner’s manual.  
Unpacking  
DO save all packing materials for possible future shipping needs.  
DO inspect the Nº512 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 box from the carton. Make

Mark Levinson  
Placement and  
Ventilation  
DO install the Nº512 CD/SACD player on its own shelf for proper  
ventilation.  
DO install the Nº512 chassis on a solid, flat, level surface.  
DO install the Nº512 CD/SACD player 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 the  
CD/SACD player for proper heat dissipation.  
DO NOT place the Nº512 on a thick rug or carpet or cover the  
Nº512 CD/SACD player with a cloth, as this might prevent proper  
cooling.  
DO NOT expose the Nº512 CD/SACD player to high temperatures,  
humidity, steam, smoke, dampness, or excessive dust. Avoid  
installing the player near radiators and other heat-producing  
appliances.  
DO NOT install the Nº512 near unshielded TV or FM antennas,  
cable TV decoders, or other RF-emitting devices that might cause  
interference.  
4
DO NOT place the Nº512 on a window sill or in any location  
where it will be exposed to direct sunlight.  
DO NOT obstruct the IR (infrared) receiver/transmitter located on  
the front panel display. The remote control must be in line-of-sight  
with the front panel IR receiver. If strong sunlight or fluorescent  
light shines on the IR receiver, the remote control may be  
unreliable.  
Warning!  
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 may  
result in personal injuries and/or product damage.  
Nº512 CD/SACD™ Player

Note  
If you record a disc using a personal computer, even if it is recorded in  
a compatible format, there are cases in which it may not play because  
of the settings of the application software used to create the disc. Check  
with the owner’s manual of the software application for more detailed  
information.  
Handling and Care of Discs  
Discs require special care and handling to ensure their optimal  
performance. Pay particular attention to the following:  
DO remove the disc from its storage case by pressing down on the  
center of the case and lifting the disc out, holding it carefully by the  
edges.  
DO hold the disc at its center hole and outer edges. Avoid handling  
the sides of the disc.  
DO load single-sided discs with the label side facing upward, and  
double-sided discs with the side intended for playback facing  
downward. All loaded discs must align with the circular guide inside  
the disc drawer.  
Mark Levinson  
DO return discs to their cases when not in use. Discs should be  
stored in an upright position out of direct sunlight and excessive  
heat, humidity or cold. Long exposure to high temperatures may  
warp the disc.  
DO clean a dirty disc by carefully wiping the recorded surface of  
the disc from the hole in the center straight outward towards the  
outer edge with a soft, dry cloth.  
Caution!  
Dirty or damaged discs might affect playback performance or  
damage the player. DO NOT attempt to load a cracked, chipped,  
scratched, warped, dirty, or otherwise damaged disc into the disc  
drawer.  
DO NOT use chemicals such as record sprays, antistatic sprays or  
fluids, benzine or thinner to clean the disc. Such chemicals may do  
irreparable damage to the disc’s plastic surface.  
DO NOT use irregularly shaped discs, as they may damage the  
player. Mini discs may be used so long as they can be properly  
seated in the disc drawer.  
DO NOT write on the disc label or disc surface with ballpoint  
pens, pencils or other sharp-tipped writing instruments. Do not  
glue paper or attach stickers to discs. Although not as fragile as the  
recorded side, damage to the label side of the disc can render the  
disc unplayable.  
8
Caution!  
The No512 is a single disc player. DO NOT attempt to insert more  
than one disc into the disc drawer at a time. This may cause  
damage to the player, disc or both.

Provide two balanced XLR and two single-ended (unbalanced) RCA  
connectors for the stereo analog audio output.  
1. Analog Outputs  
The pin assignments, shown on the left, of the XLR-type female  
input connector are consistent with the standards adopted by the  
Audio Engineering Society. Refer to the operating manual of your  
preamplifier to ensure that the pin assignments of its balanced  
output connectors correspond to the Mark Levinson Nº512 CD/  
SACD player. If not, wire the cables so that the appropriate input  
pin connects to the equivalent output pin.  
Pin Assignments:  
Pin 1: Signal Ground  
Pin 2: Signal + (non-inverting)  
Pin 3: Signal – (inverting)  
Connector shell is chassis ground  
Provide an AES/EBU or an S/PDIF connector for the digital audio  
output.  
2. Digital Outputs  
Accepts the input of IR (infrared) signals from other equipment. The  
3.5mm jack accepts a stereo or mono plug.  
3. IR Input  
Nº512 CD/SACD™ Player  
Provides serial control through a standard RS-232 connection. Refer  
to the separate document, Nº512 Serial Protocol Definitions, for  
further details.  
4. RS-232 Control port  
Used to support external or ML Net control over a standard  
Ethernet network. For information on how to set up and use the  
Ethernet port, refer to the “Network Setup” and “ML Net” sections  
found later in this manual.  
5. Ethernet port  
Used to activate other components in the home entertainment  
system, such as amplifiers, lights, window shades, and video  
screens. The rear panel of the Nº512 has two trigger connectors –  
one input and one output. The trigger input can receive a 12V DC  
signal from a connected component. The trigger input passes  
through to the trigger output signal, enabling a daisy-chain of  
devices to be controlled by a single trigger signal.  
6. Trigger Input and  
Output  
Receiving a trigger signal causes the Nº512 to change its power state.  
If the Nº512 is in Standby mode, it is powered on when a 12V DC  
signal is received on the trigger input. Conversely, if the Nº512 is  
powered on, then 0V DC on the trigger signal puts the Nº512 into  
Standby mode.  
The Trigger Output goes to 12V DC when the Nº512 is powered on  
and goes to 0V DC when the Nº512 is placed into Standby mode or  
powered off.  
17  
Provides AC power to the Nº512 when the supplied power cord is  
connected from the AC input connector on the Nº512 rear panel to  
an electrical outlet.  
7. AC Input  
Caution!  
Before operating the No512, 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.

(off) to 73.2 (maximum volume). The variable volume level defaults  
to 30 when the Nº512 is taken out of Standby mode or powered on,  
or if the volume is changed from Fixed to Variable.  
If the Volume Fixed LED is lit, then the volume is set to a fixed level  
and cannot be changed with the remote control Volume buttons.  
The fixed level is the line level, or 61.2, and is only available when  
using the analog outputs. We recommend using this option only if  
you are using the system-level volume controls in a pre-amplifier or  
media console.  
23  
Note  
Different layers on an SACD disc may have some variance in volume  
level. We recommend lowering the volume before changing layers to  
avoid potentially loud volume level variances.

Internal Web Page  
When connected to a computer, the Nº512 has an internal Web  
page that provides access to:  
•
Network Setup – allows the user to modify the network setup  
parameters. Accessing the internal Web page is the ONLY way  
to modify the network setup parameters of the Nº512 player.  
•
•
Status Information – provides basic status information for  
the Nº512.  
Display Intensity – allows the Nº512 front panel display and  
LED brightness level to be adjusted. Use the pulldown menu to  
select one of the four brightness settings available - High,  
Medium, Low, and Off.  
The Nº512 MUST be connected to a computer via the Ethernet port  
before you can access the internal Web page. Continue to the next  
section - “Network Setup” - for further instructions.  
The Web page also has a Restore Defaults button, which resets the  
parameters to their factory default values. Clicking the Restore  
Defaults button displays a pop-up asking for confirmation; click Yes  
to restore the factory default values.

Network Setup  
The Nº512 CD/SACD player supports a network connection  
through the Ethernet port. The Nº512 can connect to a network  
through use of a router or directly to a computer.  
The Nº512 can be:  
1. Connected to a router with DHCP active – We highly  
recommend using this option. Since 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  
Note  
The Nº512 does not support wireless connection. However, a cable  
attached from the player to a wireless adapter can be used to interface

Network Setup  
Parameters  
•
Static IP Address – provides a fixed IP address. This IP  
address is NOT automatically selected; it must be entered. If  
DHCP is on, then an IP address doesn’t need to be entered.  
IP address 192.168.50.8 is the factory default value.  
•
Subnet Mask – identifies the subnet mask for the Nº512.  
This IP address is automatically assigned by DHCP. If DHCP  
is off, then the address must be entered manually and it  
must agree with the subnet mask address of the router. IP  
address 255.255.255.0 is the factory default value.  
•
Host Name – indicates the network name given to the  
Nº512 player. The host name is made up of two parts that  
are separated by an underscore. The first part contains one  
Mark Levinson  
to eight characters that can be modified via the internal  
Web page. The second part contains the last six characters  
of the MAC address for each Nº512. This MAC address is  
unique for every player.  
The Host Name default is “NO512_xxxxxx” where “xxxxxx”  
stands for the last six characters of the unique MAC address  
for each player.  
•
DHCP – turns the DHCP capability on or off. When  
activated, DHCP assigns a unique IP address to the Nº512.  
The factory default value is On. We recommend leaving DHCP  
set to On.  
If you are using a router with DHCP active to connect to the Nº512,  
use this procedure. Otherwise, skip to the next procedure.  
Connecting With  
DHCP  
(Recommended)  
Connect one Nº512 player to the router, as described in the earlier  
“Connecting the Cables” section. Make sure that everything is  
powered off before making cable connections.

3. On the computer, open the Internet Explorer Web browser.  
4. Access the status page of the router to identify the name of the  
Nº512 player. Refer to your router’s owner’s manual to  
determine how to access the status page.  
Most routers identify the device names of all located devices on  
the status page. However, some may only list the assigned IP  
address.  
Note  
If you are using ML Net, you can also use the Nº502 to determine the  
name of the Nº512 player. Refer to the ML Net section of the Nº502  
Owner’s Manual for further details.  
5. Type the name or assigned IP address of the Nº512 player into  
the address (URL) line of the web browser and press the Enter  
button.  
6. The Nº512 internal Web page is now displayed. The top of the  
page provides the general status of the Nº512. The bottom of

Mark Levinson  
ML Net  
The ML Net protocol allows you to control two or more Mark  
Levinson products simultaneously via the Ethernet port.  
Note  
Since ML Net operates through the use of a router and the Ethernet  
connection, all devices must have networking capability. Refer to the  
previous “Network Setup” section to set up the Nº512 for network  
operation.  
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 Nº512 CD/SACD player is always a slave device. A separate  
master device must be used in conjunction with the Nº512 player.  
As a slave device, the Nº512 responds to the following ML Net  
commands sent from the master device:  
36  
•
Standby State – the master device controls the Standby state  
of the Nº512 player.  
•
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 Nº512 to the network.  
Nº512 CD/SACD™ Player  
The figure below illustrates a typical ML Net setup:  
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.  
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.  
Discovering Slaves

the rear panel connector of the Nº512 and an electrical outlet.  
No Power  
2. Make sure the Nº512 is powered on with the Power button.  
3. Make sure the Nº512 is not in Standby mode.  
4. Examine the electrical circuit breaker to ensure that power is being  
supplied to the electrical outlet to which the Nº512 is connected.  
5. Verify that the power rating on the rear panel of the Nº512  
matches the power rating of the electrical outlet. If the power  
levels do not match, then no power is sent to the outputs of the  
player.  
6. Verify that the AC Mains fuse on the rear panel of the Nº512 is not  
blown. For further instructions, refer to the “Replacing the AC  
Mains Fuse” description in the “Care and Maintenance” section  
that follows.  
38  
1. Make sure that the Nº512 is powered on and playing audio.  
No Output  
2. Verify that the Nº512 is not in Pause mode. The display should  
not show the double bar (||) symbol.  
3. Verify that Mute is turned off.  
4. Verify that the volume level is set to an audible level.  
5. Examine cables to ensure a solid connection between the Nº512  
and associated components.  
6. If using the digital outputs, verify that the disc in the player is  
not an SACD disc and that the front panel SACD LED is not lit.  
7. Verify that the power rating on the Nº512 rear panel matches the  
power rating of the electrical outlet. If the power levels do not  
match, then power is NOT sent to the outputs of the player.  
Verify that Display Intensity parameter has not been set to Off.  
Press the Display button on the front panel, or the Display Intensity  
button on the remote control to access the parameter. Ensure that  
Off is not selected.

Play  
2. Verify that the disc is not scratched or otherwise damaged.  
3. Verify that the disc is not dusty, soiled, or marked with  
fingerprints.  
4. Reload the disc, making sure that the disc is firmly seated in the  
tray and the label is facing up.  
5. Verify that the loaded disc is NOT blank.  
1. If a cable TV connection is present, disconnect the cable from  
the wall outlet. If this eliminates the humming sound, a ground  
loop isolation device is required. Contact your dealer or cable  
provider for assistance.  
Audio Has a Humming  
Sound  
2. Disconnect the components one at a time to isolate the  
problem. Once the problem is identified, make sure the  
associated component is properly grounded and connected to  
the same electrical circuit as the Nº512.  
39  
1. Eliminate obstructions between the remote control IR  
transmitter and the front panel display IR receiver/transmitter.  
The remote control must be in line-of-sight with the front panel  
IR receiver for proper operation.  
Remote Control  
Doesn’t Work  
2. Replace the remote control batteries. Verify that the remote  
control batteries are inserted correctly with the proper polarity.  
3. Make sure the IR input connector is not being used.  
4. Make sure the front panel display IR receiver/transmitter is not  
exposed to strong sunlight, halogen light, or fluorescent light.  
This can cause IR reception to become unreliable. If the Nº512 is  
placed inside a glass cabinet, tinted glass will reduce the remote  
control range.  
5. If you have multiple Mark Levinson products, verify that you  
are using the proper remote control for the product in question.  
1. Verify that the Nº512 is not positioned too close to RF-emitting  
devices. Move such items one at a time to isolate which device is  
causing the problem.  
RF Interference  
2. Replace unshielded cables with shielded cables wherever  
possible.  
Mark Levinson  
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.  
Can’t Assign in ML Net  
If the current state is assigned, you must first unassign it from the  
ML Net system. Once a slave is assigned, it will not accept another  
assignment until it has first been unassigned. Once the device is  
unassigned, you can then reassign it to the desired ML Net system.  
For further explanations on assigning slave devices, refer to the  
owner’s manual of the master device.  
1. Verify that the master device and the Nº512 are properly  
connected together with a router.
