Getting Started

Modify the default Device Names. Select DEVICES (1 below). Click on a device type header (Processor, Milan Loudspeakers, etc.) to expand/collapse the list of devices by type. For each listed device, double-click the name and modify the text (2 below). These names are stored in the devices and are used to correlate devices listed in software to the physical devices.

NOTE: For arrays, a good strategy is to start each name with with a number to indicate position in the array followed by a letter or combination of letters to denote the array. This aids when searching for devices and sorting columns. The number at the end of the default name is the serial number of the loudspeaker. For example:

01 Left Main Panther
02 Left Main Panther

NOTE: For network switches, the last three octets of the Milan identity name match those of the devices MAC address. If renaming, including the last three octets may be helpful. For example:

FE-A0-6B-64, renamed: FOH Primary A0-6B-64

NOTE: Duplicate Device Names within the same Group Name are not allowed.

To match devices listed in Nebra to physical devices, use the Wink function. Click once on a device in Devices (1 below) or a device in the Connections Workspace to open the Sidebar panel. Click the Wink icon (2 below) to turn on the device’s Wink LED(s). Conversely, press the Wink button on the device, which will be indicated in Nebra.

Nebra, Devices – Click Wink Icon to Turn on Device’s Wink LED

NOTE: The Wink function of PANTHER and 2100-LFC loudspeakers automatically times out after several seconds. The Wink function of other loudspeakers and devices is active until the Wink icon in Nebra is clicked or the Wink button on the device is pushed.

NOTE: To change the device name, double-click the device name at the top of the Sidebar panel.

Assign each device a Group Name. Double-click the text in the Group Name column to edit the Group Name.

NOTE: Group Names are used to organize devices (e.g., location, type, array, etc.) and are included when using the search function in Nebra.

NOTE: For Galileo GALAXY processors in Spacemap Go mode, reserve and assign a unique Group Name for these processors. Do not assign the reserved Group Name to processors not in Spacemap mode to avoid network communication issues.
