Connecting the Devices

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 “Network Setup” section of this manual to set up the Nº53 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 Nº53 Reference power amplifier is always a slave device. A separate master device must be used in conjunction with the Nº53 amplifier.

As a slave device, the Nº53 responds to the following ML Net
commands sent from the master device:	21

•Status Reporting – status conditions of the Nº53 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 Nº53 amplifier.

•Synchronized LEDs – the Standby LEDs of the master device and all assigned slave devices blink in unison.

The Status LED on the front panel of the Nº53 does not blink if the amplifier is in Power Save mode.

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 Nº53 to the network.
