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 section of this manual, “Network Setup”, to set up the Nº532
for network operation.
Masters and Slaves
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 Nº532 dual monaural power amplifier is always a slave device.
A separate master device must be used in conjunction with the
Nº532 amplifier.
As a slave device, the Nº532 responds to the following ML Net
commands sent from the master device:
• Status Reporting – status conditions of the Nº532 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 Nº532 amplifier.
• Synchronized LEDs – the Standby LEDS of the master device
and all assigned slave devices blink in unison.
Note The Status LED on the front panel of the Nº532 does not blink if the
amplifier is in the Power Save mode.
Connecting the
Devices
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 Nº532 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.
