NEXO NeMo User Guide v1.3
Thanks for downloading NEXO NeMo for iOS. This manual presents the app’s
functionalities and how to use it step by step.
PRESENTATION
NEXO NeMo is the remote control app for mobile terminals of a set of NEXO NXAMP
powered TD-controllers. It allows you to control from an Apple iPad, iPhone or iPod
Touch and through a Wi-Fi network one or many NXAMPs. Managing and positioning
amplifiers, monitoring their parameters (levels, etc.), and setting new values
(volume, delay, setup, etc.) is made possible thanks to an attractive and intuitive
user interface.
Its main functionalities include:
Visualizing and positioning the connected NXAMPs within a 2D space.
Quickly muting, soloing and monitoring the status, including peak and
protect, for the entire network.
Adding background pictures from your library.
Grouping amplifiers for multi-device control, and visualizing groups on the 2D
space.
Muting and soloing, and monitoring the status of groups of NXAMPs.
Quickly muting and soloing individual channels of a group of NXAMPs.
Monitoring and controlling simultaneously parameters of several amplifiers,
among which mute-solo, input and output levels, and volume, delay, gain,
array-EQ and headroom of each output channel.
Patching input channels to output channels.
Selecting setups from the standard library, and building custom setups.
Saving and recalling scenes.
Undoing and redoing every control step.
Copying and pasting parameters and scenes from one to many NXAMPs.
Saving and sharing user configurations, thanks to Sessions (.nemo
documents).
A configurable way of managing alerts of different levels.
Visualizing and exporting a log of all the values of the NXAMPs (including
temperature, voltage, current…) that you can record when NeMo is
connected.
A fully configurable Live mode.
A Demo mode to test the app.
A use in portrait on iPhone and iPad, and in portrait or landscape mode on
iPad.
Requires AVS-Service and NXES104 or NXDT104 remote control cards in the
NXAMPs. No theoretical limit on the supported numbers of NXAMPs, neither on the
number of connected NeMos. Compatible with AVS-Monitor.
What’s new v1.3
Ready for iOS 7! New improved style and performances.
Introduction of .nemo, a new file format to save and share (mail, AirDrop…)
your sessions.
Page 2 of 50
NEXO NeMo User Guide v1.3
Caution: NEXO NeMo usage
Only use this application during a live event with an extreme care. In particular,
you should activate the safe mode.
Please equip your NXAMPs and iDevice with the latest firmware update, and your
computer with the latest version of AVS-Service and AVS-Monitor.
The good functioning of NeMo depends on the one of the wireless network and of
AVS-Service.
Caution: before updating
Before updating NeMo, if need be, please export the log file (see Error! Reference
ource not found.), since the internal log database is likely to be updated and all its
items to be removed.
As this version introduces a new way of handling sessions, your configuration will
be lost. You can save the file savedParameters.plist (NeMo v1.0 to v1.2) not to
lose it.
Undo/Redo: now, it is possible to undo and redo every control step you make.
Copy/Paste: it is possible to copy parameters from one NXAMP to one or
several NXAMPs. With Load 3.16, scenes can also be shared between
NXAMPs.
Improved log, introduction of Log Records: select the one you want to record
on, and press [R]. As many Log Records as wanted can be created (e.g. one
per session).
New Events menu (prev. Alerts & Tasks), grouping alerts in sets, with
improved tasks display, and with a System Status section.
New way of accessing the Live mode (prev. long press gesture), with a button
at the bottom left corner of the screen.
Pull to Refresh functionality in the Groups & Devices menu.
Smart Sliders in the control page: in case of multiple values, sliders become
green and have marks for all the different values.

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.com/en/support/software.
Wi-Fi access point
A Wi-Fi access point has to be connected to the NXAMPs' local network, and
configured following the manufacturer’s instructions. The following points
might help you to get an optimal configuration in terms of rapidity and
robustness:
Preferably choose a router that supports 802.11n. It is recommended to
activate the support of all the modes (802.11n/a for the 5 GHz band,
802.11n/b/g for the 2.4 GHz band). The 5 GHz band is more robust to
interferences than the 2.4 GHz band, but the range is generally shorter.
Select a bandwidth of 20 MHz for the 2.4 GHz band, or of 20 and 40 MHz for
the 5 GHz band.
For a robust and large-coverage Wi-Fi network, preferably use
professional routers with adaptive antennas and beam emitting (e.g. Ruckus
Wireless).
Use DHCP rather than static IP address assignation. There should be only
one DHCP server on the network. In order to give a static address to one of
the devices (e.g. the computer running AVS-Service), go to the settings
interface of your router.
Check that the firmware of the access point is up-to-date.
Give the wireless network a unique SSID name.
Choose a security mode, preferably WPA2-Personal (AES), or, at least,
WPA/WPA2.
Disable the parameter Hidden network of the Wi-Fi access point, and MAC
(Media Access Control) address filtering, security being guaranteed by the
point above.
If possible, choose Auto Channel Selection, else, make sure that the
chosen channel is free from other routers and potential interference sources
(microwave ovens, cable of satellite dishes, power lines and other electrical

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. Install AVS-Monitor
on a computer;
2. Link this computer, preferably with an Ethernet link, to the NXAMPs and
router’s network (a Wi-Fi connection is however possible);
3. Launch AVS-Control Panel (available at Start/All
Programs/AuviTran/EtherSound Monitor/);
4. In the Status tab, select the adequate EtherSound and Dante Adapters
(the ones leading to the NXAMPs’ network);
5. Select All in the Software client Adapter list;
6. If needed, check Enable Dante Control in the AVS-Service tab.
7. Start the service by pressing [Turn ON].

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). It is possible to have several
Primary Masters thanks to a switch. Other devices than NXAMPs can be
connected to the network (consoles, toolboxes, Stage Boxes, etc.). It is
strongly not recommended to have a wireless link between the host
computer (where AVS-Service is running) and the NXAMPs. Generally
speaking, mind separating the audio network and the network with the
Wi-Fi access point. Also, you might need to separate other proprietary
networks (Lake, etc.).
iDevice
The iDevice (iPhone, iPod Touch or iPad) should be equipped with iOS 7 or
later, and with the NeMo app.
Wi-Fi should be activated on the iDevice. For that purpose, go to Settings.
Disable the Plane mode if needed. Select Wi-Fi, and choose the correct
network. Authenticate yourself if the network is secured.
If you are using static IP, tap on , choose Static, and type in an IP
Address for the iDevice (similar to the router address, but with a different last
number), a Subset Mask (generally 255.255.255.0.0), and the Router address
(usually printed on the bottom of the router, or manually defined when setting
the router up). But again, DHCP is preferred, since it ensures more stability.
Page 8 of 50
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].
If Wi-Fi signal is surprisingly low on old iDevices, you can disable automatic
setting of luminosity and set luminosity to its maximum level, and avoid
holding your iPad by the right (if portrait) or down (if landscape) part of the
main button (« death grip »).

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.
Config Mode
Configuration mode. All settings are enabled.
Live Mode
Safe mode. This mode can be configured from the Settings menu. A
setting can be disabled or enabled after confirmation. Cf. Security.
Demo Mode
This mode can be used without any network connection, to test the
app on virtual amplifiers. It can be a good way to learn how to use it.
GETTING STARTED
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). You can find it using a Wi-Fi Scanner
on your iDevice (e.g. Fing). Alternately, you can go to Windows'
Control Panel>Network and Internet>Network and Sharing Center.
There, choose your network (named for instance Local Area
Connection). In the new window, press [Details…] and note the IPv4
Address.
3. Choose the session you want to open (cf. Sessions). When you launch
NeMo for the first time, an empty session is created for you by
default.
4. Tap on [Config] or [Live] to open the session, or on [Demo]. Connecting
can take a few moments. You can cancel the connection at any time
by tapping on [Cancel].
5. If the access to AVS-Service is restrained (see AVS-Control Panel, tab
Security), you are invited to enter a login and password.
6. The status of the connection is displayed. When it is “Loading
devices…”, the connection with AVS-Service is engaged, you may
have to be patient!
If an error message is displayed, maybe:
Wi-Fi connection cannot be achieved. Please refer to the Preliminary
section of this document to solve this problem.
The given IP address is not the good one.
AVS-Service is not working correctly.

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.
To show or hide links, tap on or in the toolbar.
Map of the devices, map of the groups
The map of the main view can show either the devices (NXAMPs and
other devices) or the groups (see further how to create groups). To
activate the map of the devices or of the groups, tap on [Devices] or
[Groups] in the toolbar.
Selection
The control of the NXAMPs3 (see following tabs) is achieved with a system
of selection.
Double tap to select a cell. Its color is then shinier.
Double tap to deselect a cell. Its color is darker.
To select all the cells, tap on in the toolbar.
To deselect all the cells, tap on in the toolbar.
A group cell (iPad only) can be partially selected, if only part of its devices
is selected. If so, it has slanted strips of bright and dark color.
The number of selected cells is displayed at the bottom of the main view.
To locate the selected cells on the screen, tap on .
It is also possible to select or deselect NXAMPs and groups from the menu
[Groups & devices...] (see The Groups & devices menu below).
Even if any cell can be selected, only NXAMPs are controllable.
Positioning cells
You can arrange cells as you like. To do so, tap and hold to drag one or
many cells with your fingers. When two cells are close enough, magnets
allow the constitution of stacks, like racks: you can reproduce the
From now on, « NXAMP » and « amplifier » are equally used.

Tip: align on a grid
You can align cells on a grid. To do so, go to the Preferences menu from the
welcome page, and activate the switch Align on a grid.
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.
If many cells are selected, and you drag a cell that is not selected, then
only the later will move.
To automatically place cells on the map, tap on in the toolbar. You
can then choose between placing them hierarchically (masters above
slaves, only for EtherSound) or as tiles.
Groups
NeMo makes it easy for you to manage NXAMPs, offering you the
possibility of grouping them. For instance, if you want to perform an
operation on several devices at once, you can group them together.
Groups can also make it easy to identify amplifiers, for instance belonging
to a same rack or dealing with the same cabinets. A group has a name,
and is associated with a color. Cells from a same group are colored with
the group's color.
Creating a group:
1. Tap on [+] in the tool bar ;
2. In the displayed popover, tap on [Add] and select the devices of your
choice. By default, the devices that are selected on the map are
selected here.
3. Adding devices to a new group: NeMo suggests a name and a color for
the new group. Tap on the “Group XX” text field to change its name.
Tap on a color icon to change its color. Validate by pressing the [Done]
button of the keyboard or the [Create group] button.
Adding devices to an existing group: Locate the group of your choice in the
list and tap on it.
Groups can also be created and edited from the Groups & devices menu
(see The Groups & devices menu).
