OVERVIEW OVERVIEW INTRODUCING THE MARK LEVINSON NO5302 POWER AMPLIFIER Congratulations on your purchase of a Mark Levinson® power amplifier. You now possess one of the finest audio reproduction devices in the world, a product that will provide an exceptional music listening experience for years to come. The N05302 harnesses decades of superlative audio engineering and the latest advancements to deliver unmatched performance and value.
INSTALLATION INSTALLATION UNPACKING PLACEMENT AND VENTILATION When unpacking your N05302: • Install the power amplifier on a shelf with nothing above it, such as the top shelf in an open rack, to ensure proper ventilation. DO NOT install the power amplifier inside of an enclosed cabinet or rack. • Save all packing materials in case you need to ship your amplifier in the future. • Inspect your amplifier for signs of damage during shipment.
INSTALLATION POWER REQUIREMENTS The N05302 is configured at the factory for 100, 115, or 230 VAC power operation at 50Hz or 60Hz. Before operating the amplifier, 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 N05302 is sold is included.

CONNECTIONS EXTERNAL COMPONENT CONNECTIONS CAUTION: Before making connections, make sure the N05302 and all associated components are powered off and disconnected from electrical outlets. One balanced and one single-ended (unbalanced) connector are available for each audio channel input. Balanced inputs: The N05302 has two balanced XLR input connectors which accept left-channel and right-channel balanced input signals from source components with balanced XLR type output connectors.
CONNECTIONS Speaker output binding posts: The amplifier features goldplated, high-current loudspeaker binding posts. The positive binding posts, labeled + (positive), are red; the negative binding posts are black and are labeled – (negative). The binding posts accept bare wire, spade lugs and banana plugs as illustrated. For bare wire and spade lugs, first loosen the binding post thumb nut, insert the wire or spade and fingertighten the nut. For banana plugs, simply insert the plug into the binding post.
CONNECTIONS USB port: This USB Type-A connector allows you to perform firmware upgrades that may be offered in the future, and to import and export setup configurations via a standard USB drive or memory stick (FAT32 formatted). Firmware updates may also be accomplished via download when the unit is connected to a local area network (LAN) via an Ethernet cable. (See page 13 for more detailed firmware update instructions.

CONTROL CONTROL The N05302 is highly flexible and allows a variety of means of setup and control including IP, IR (input), RS232, trigger and 3rd party control systems. For most applications simply switching between Standby and On would be the extent of the control needed. Additionally, an internal webpage allows technicians and advanced users access to power operation parameters, diagnostic information, and firmware updates using a PC or tablet and a standard web browser.
CONTROL BROWSER SETUP PAGE (BSP) The BSP is a highly convenient means of selecting the Standby mode, keeping the firmware of your amplifier up to date, and monitoring operational faults and parameters. It is accessed via an up-to-date web browser on a PC or tablet. In order to access the BSP, you must first connect the unit to your Local Area Network (LAN).
SETUP SETUP Connect your Mark Levinson amplifier to a PC or tablet via your home network as described above and open a browser. Network speed and quality of the connection will affect the response time of the BSP. SETUP MENU Click the Setup menu button on the left side of the BSP screen to reveal a series of collapsible sub-menus. Browser method: Make sure your unit is connected to a network with Internet access. Click the SW Update button to open the Mark Levinson FTP site.
SETUP Reload Click to open a webpage that displays the N05302’s configuration information. Save Click to save the webpage setup configuration settings. Restore Click to restore the amplifier to the factory settings. The unit will enter the “green” Standby mode when the restoration is complete. The amplifier will lose network connection after this step. Use the front panel Standby switch to exit standby mode and restore your network connection as outlined on page 12.
SETUP NETWORK TRIGGER Click Network to expand the menu. This menu offers access to the following network-related parameters. They are useful only if you want to connect your unit to a network to access controls and setup functions via PC or tablet. Trigger: This setting configures the 12V trigger. NOTE: Using a trigger input overrides the Standby button. Name: Displays your N 5302’s network name in this format N5302XXXX (the X’s represent the last four characters of the unit’s unique MAC address).
SETUP FAULTS CONFIG This page displays the fault threshold values for important operational parameters. These values are informational for use by technicians and are not user adjustable. This sub-menu group allows you to import or export Setup configuration settings. Config Export: Once you have your unit’s configuration precisely as you would like it, we strongly recommend you save a Config Export file to a local drive or thumb drive in case an untoward event erases your configuration settings.
SETUP UTILITY MENU ADVANCED UPDATE MENU When clicked, this menu item opens a page where you will see various status indicators, including operating temperature (shown in degrees Celsius). In the unlikely event of a failure, note the indicators and open the “Fault History” file. This data may help you or a technician diagnose any amplifier malfunctions or adverse conditions. This page’s functions are used for uploading individual software files from the FTP server, a USB drive or your PC’s hard drive.
TROUBLESHOOTING TROUBLESHOOTING Incorrect operation is sometimes mistaken for malfunction. If problems occur, see this section for troubleshooting information. If problems persist, contact your authorized Mark Levinson dealer. NO POWER Examine the power cord to ensure that it is connected to both the AC mains connector and a working, unswitched electrical outlet. Examine the electrical circuit breaker to ensure that power is being supplied to the electrical outlet to which the amplifier is connected.
TROUBLESHOOTING IF ALL ELSE FAILS… Power cycle the amplifier by disconnecting the power cord from the AC mains, waiting at least 10 seconds before re-connecting power. Repeat the process two more times. Restore factory-default settings (See Config tab on Setup menu on the Browser Setup Page. See page 16). Contact your authorized Mark Levinson dealer. Contact Mark Levinson Customer Service at 888-691-4171 or marklevinson.com.
