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.
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.
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:
• 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.
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.
