Installation Considerations The Nº500H series power amplifier 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.
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.
Nº500H Series Power Amplifier 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.
Mark Levinson Front Panel The front panel contains one LED and one Standby button – as shown. Status LED standby Standby Button Standby Button Places the amplifier into Standby mode. Pressing the button while the amplifier is in Standby mode turns on the amplifier. 6 Standby mode powers only the low-voltage power supply, control, and communication circuits. Status LED Indicates the operating state of the amplifier and provides basic diagnostic information if a fault condition occurs.
Nº500H Series Power Amplifier Rear Panel The images below show a one-channel, two-channel, three-channel and five-channel rear panel view.
Mark Levinson Audio Channel Inputs One balanced and one single-ended (unbalanced) connector is available for each audio channel input. Single-Ended Inputs The RCA connectors accept single-ended signals from preamplifiers with singled-ended (RCA) outputs. A small toggle switch is provided to select either the balanced (XLR) or single-ended (RCA) input connector on each channel.
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.
Mark Levinson 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.
Nº500H Series Power Amplifier Computer Requirements Note Connecting the Cables The PC-compatible computer used to connect to the Nº500H series must have the following software installed: • Windows® 2000 or Windows XP® • eb browser (Microsoft® Internet Explorer® 6.0 or higher W preferred) If DHCP is not active, the computer must be set up with a Static IP address. Refer to the “Setting Up the Computer” procedure found later in this section for instructions.
Mark Levinson Internal Web Page When connected to a computer, the Nº500H series has an internal Web page that provides access to: • etwork Setup – allows the user to modify the network setup N parameters. Accessing the internal Web page is the ONLY way to modify the network setup parameters of the Nº500H series amplifier. • tatus Information – provides basic status information of S the Nº500H series amplifier.
Nº500H Series Power Amplifier • ubnet Mask – identifies the subnet mask for the Nº500H S series. This IP address is automatically assigned by DHCP. If DHCP is off, then the address must be entered manually and must agree with the subnet mask address of the router. IP address 255.255.255.0 is the factory default value for the Nº500H series. • ost Name – indicates the network name given to the H Nº500H series amplifier.
Mark Levinson Setting Up the Computer Note If DHCP is not used, then the computer must be set up too. Use this procedure to set up the computer, then continue to the next procedure to connect to the amplifier. For the computer to find the amplifier, the LAN (Local Area Network) and TCP/IP (Internet Protocol) settings of the computer must be set up. The parameter setups vary slightly depending upon the operating system of the computer.
Nº500H Series Power Amplifier Network Setup for Windows 2000 1. From the Start menu, select Settings Control Panel. 2. Double-click on the Network and Dial-Up Connections option. 3. Double-click on the Local Area Connection option. 4. Click the Properties button to open the Local Area Connection Properties menu. If the computer is not currently connected to an active network, Step 3 has already opened the Local Area Connection Properties menu. 5.
Mark Levinson 3. S et up the router to the IP address 192.168.50.x – where x stands for a number other than 0, 3, 4, 5, 255, or the number used for the computer IP address. The router must be on the same subnet as the amplifier and the computer, but also must have its own unique address. Refer to the router’s owner’s manual for instructions on how to modify the IP address. 4. Press the Power button on the amplifier. 5. On the computer, open the Internet Explorer Web browser. 6.
Nº500H Series Power Amplifier Direct Connection Use this procedure to connect directly to a computer if you are not using a router. For the computer to find the amplifier, the TCP/ IP and LAN settings of the computer must be set up. Refer to the earlier “Setting up the Computer” procedure for instructions. 1. Connect the amplifier to the computer, as described in the earlier “Connecting the Cables” procedure. Make sure that both the amplifier and the computer are powered off before connecting. 2.
Mark Levinson ML Net The ML Net protocol allows you to control two or more Mark Levinson products simultaneously via the Ethernet port. Note Masters and Slaves 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.
Nº500H Series Power Amplifier The figure below illustrates a typical ML Net setup: Nº532 Media Console (Master) Nº500 Series Power Amplifier #1 (Slave) Router Nº500 Series Power Amplifier #4 (Slave) Nº500 Series Power Amplifier #3 (Slave) Nº500 Series Power Amplifier #2 (Slave) 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.
