NEXO NeMo User Guide v1.3 PRELIMINARY Network NXAMPs Every NEXO NXAMP has to be equipped with an NXES104 or NXDT104 card, and has to be linked, directly or through other networking devices (switches, etc.), to a local network. The device(s) at the top of chain (called Primary Masters) should be connected to the network via the Primary or Remote port of the EtherSound™ or Dante™ card. It is highly recommended to keep the NXAMPs updated with the latest firmware version, available at: http://nexo-sa.
NEXO NeMo User Guide v1.3 sources, phones, video senders, wireless speakers and other wireless devices operating within the 2.4 or 5 GHz bands). To that purpose, you can use a WiFi scanner software. In case of high latency while using NeMo, you can reboot the router. For more information, please consult the router manual, and Apple articles about recommended settings1. AVS-Service AuviTran’s AVS-Service must run on a host PC (or Virtual Machine on a Mac). For this purpose, you need to: 1.
NEXO NeMo User Guide v1.3 You can find more details in the documentation of AVS-Service and AVSMonitor. In case of high latency while using NeMo, you can: Go to the Status tab, and press [Turn OFF] then [Turn ON]; Try another value for the Network timeout (AVS-Service tab), 5 ms by default. Configuration The following figure shows the optimal configuration. It is possible to connect the Primary Master device directly to the computer (if this computer has two network adapters).
NEXO NeMo User Guide v1.3 In case of frequent disconnections of NeMo, go to Settings>Wi-Fi, tap on near to your network, and then [Forget this Network]. Start again the operations above. If you are using DHCP (recommended), you can also press [Renew Lease].
NEXO NeMo User Guide v1.3 GETTING STARTED Tip : import from AVS-Monitor If you are a user of AVS-Monitor, you can import your configuration (alias of the devices and groups). To do so, go to the section Import from AVS-Monitor. Starting a new session 1. Launch NeMo by tapping on the app icon. 2. You are invited to choose an IP address. It is the address of the Ethernet (or Wi-Fi if need be) network adapter of the host computer (where AVS-Service is running).
NEXO NeMo User Guide v1.3 General points When a new session is opened, the view is made of: A navigation and tool bar, from where it is possible to trigger many actions on the main view. The Groups & devices menu to select objects to handle. A main view, where monitoring and controlling NXAMPs is achieved. A button to toggle Config and Live mode (long press). A button to record and view the Log. The Events menu, to view Alerts, Tasks, and System Status. A tab bar, to change the main view.
NEXO NeMo User Guide v1.3 THE NETWORK TAB iPhone users only On iPhone, the Network tab is made of the Groups & devices menu (see The Groups & devices menu). All the following paragraphs apply to iPad users only. iPad users only The main view shows the connected devices (NXAMPs and devices from other manufacturers), as rectangular cells. Blue links between cells represent the physical connections between EtherSound™ (only) devices. A link is oriented from a master to its slaves thanks to an arrow.
NEXO NeMo User Guide v1.3 arrangement of devices as it is in reality. When two cells overlap each other, the lowermost is moved down to reach a better configuration. Two cells are completely tied when they share a full edge with each other. Then, if you move the one, the other will follow. To untie cells, put a finger on each cell, and move them away. To move simultaneously cells that are not tied, you have to select them. If you move a selected cell, all the other selected cells will move as well.
NEXO NeMo User Guide v1.3 the front, tap on the [Done] button. On the front, you will find: A mute button, to cut the output sound of an amplifier (function "overmute": mute all channels). When an NXAMP is effectively muted, the button is blue. A solo button, to mute all amplifiers, except the soloed ones. When solo is active, the button is blue. A label with the alias of the device, or the Dante ID (if applicable). Tap to display the one or the other. Four LEDs for the status of each channel.
NEXO NeMo User Guide v1.3 displayed. A device that is not an NXAMP has a cell with the alias only. A group cell A group cell has three panes: In To monitor the levels of the inputs of the NXAMPs of the group. The displayed level for an input is the maximum of this input’s levels for the NXAMPs of the group. Out To monitor the output currents and voltages of the processing channels of the NXAMPs of the group. Again, the displayed levels are the maximum through the devices of the group.
NEXO NeMo User Guide v1.3 Important: latency Since there may be latency on the wireless network, commands are likely not to be taken immediately in account by a NXAMP. For instance, it is not abnormal to wait half a second from the moment you tap on a mute button and the one it is effectively blue. All displayed values are the one that are read from the NXAMPs (except when your finger is on the thumb of a slider for instance, and except if the link with the service is broken).
NEXO NeMo User Guide v1.3 Adding background images: To add an image to the background: 1. Tap on in the toolbar; 2. Select an image from the picture library.

NEXO NeMo User Guide v1.3 Important: convention A button, a slider or an array's cell colored green means "multiple values". Follow some examples. Example 1: Here, some devices of the group Mains Left are muted and some are not. Example 2: If this slider rules the gain of the channel 1 of the two selected NXAMPs, the green color means that all the channel 1s do not have the same gain (for instance, ch.1 of the first one has its gain at -2dB, and ch.1 of another device at +3.5dB).
NEXO NeMo User Guide v1.3 THE CONTROL TAB Tap on the Control tab. The main view shows a desk where the parameters of the selected NXAMPs are monitored and controlled (see Important: selected above). In landscape mode: inputs are on the left-hand side (A to D: analog, E to H: digital from the network, EtherSound™ or Dante™), processing channels are on the right-hand side (1 to 4). In portrait mode: inputs are at the top, processing channels at the bottom.
NEXO NeMo User Guide v1.3 Gain, Array EQ, Headroom, Volume Place your finger on the thumb of a slider and move it to the left or to the right. The value of the slider is displayed next to it. Sliders have a security against too fast gestures. The resolution of the slider is different depending how far your finger is: the further it is from the slider, the finer the resolution is.
NEXO NeMo User Guide v1.3 Cabinet It is a read-only value. To set it, go to the Setup tab. Multiple values If several devices are selected, then a channel represents this channel for all the selected NXAMPs. Therefore, multiple values are possible, for instance if channel 2 of a selected NXAMP is muted, and channel 2 of another selected NXAMP is not. Multiple values are displayed the following way: Patch: links are green. Dragging your finger along a green link provokes the removal of the link.
NEXO NeMo User Guide v1.3 channels. Absolute or Relative You can choose absolute (Abs.) or relative (Rel.) modification thanks to the button [Abs.|Rel.]: If you choose Abs., and if you change the parameter (volume, etc.) of a selected channel, its value is also given to the other selected channels. For instance, moving the volume slider of a selected channel to –6 will set the volume of all selected channels to –6 dB. If you choose Rel., and if you change the parameter (volume, etc.

Scroll the list to reach the setup you want to recall.
NEXO NeMo User Guide v1.3 Multiple values Multiple loads The selected devices may have different loads, and thus different setup libraries. The displayed library is the intersection of all the libraries (i.e. a setup is displayed if and only if it belongs to all the loads). The current loads are displayed at the bottom of the view. Multiple current setups The selected devices may have different current setups (e.g. setup #1 for a device, #46 for another).
NEXO NeMo User Guide v1.3 THE SCENE TAB Tap on the Scene tab. The main view lists all the scenes of the selected NXAMPs (from 0 to 31). A scene allows you to store the settings and the current setup of a NXAMP. An empty scene is named --Empty--. If a scene is associated with a custom setup, cabinet and XO modes are displayed next to the name of the scene. Caution: scenes are not stored in NeMo, but directly in the NXAMP.
NEXO NeMo User Guide v1.3 the current scenes are selected in green. If then you recall a scene, there should be only one current scene, selected in blue. If the scenes of the selected amplifiers, with a same number, have different names, the displayed name is Multiple. If the scenes of the selected amplifiers, with a same number, have different saved cabinets, the displayed cabinets are Mult. Copy/Paste You can copy one or all the scene(s) from a NXAMP and paste them to one or many NXAMPs.
