5. INSTALLATION AND CONNECTION

5.1. Location, assembly and ventilation

The eMIMO1616 has been specially designed for incorporation within a 19" rack,
occupying 2 U’s.

It is very important that, as a heat generating element, the unit is not completely
enclosed or exposed to extreme temperatures. The passage of fresh air through the
ventilation holes on the chassis should be ensured, by leaving at least 1 U free
between each unit and those installed above and below on the rack.

If the installation includes various pieces of equipment on the same rack, or is
within a cabinet with doors, then the provision of upward forced ventilation,
through the fitting of fans on the lower and upper extremes, is highly
recommended. The upward ventilation flow will improve the dissipation of heat
generated within.

5.2. Connection to the mains supply and switching on

The eMIMO1616 is powered by an AC voltage of 90 to 264V at 47 to 63Hz. The unit
features an overdimensioned power supply unit capable of adapting to the supply
voltage in any country in the world without the need for adjustment.

The on/off switch for the unit is on the rear panel, next to the IEC mains connector.
On the front panel there is an LED ON indicator, which is lit when the unit is
functioning.

Do not allow the supply cable to become entwined or run parallel to the shielded
cables carrying the audio signal, as this could cause buzzing.

8

5.3. Local audio input connections

The eMIMO1616 has a rear panel with 8 local audio inputs, with the following
connection types available:

 INPUT 1 to INPUT 4: unbalanced stereo line-level signals, with double

connector format (RCA and Euroblock). Use either of the connectors, based
on the type of cable available between the sound source and the eMIMO1616
unit:

o Double RCA connector: connect the stereo sound source directly (CD

players, Smart phones, radio tuners, streaming players, etc.) via a
cable that delivers the left (L) channels and right (R) channels to the
white and red RCA connectors on the unit, respectively.

o Euroblock connector, 3 contacts; connect the stereo sound source in

this way:

 Left channel > L Terminal
 Right channel > R Terminal
 Earth >  Terminal

 INPUT 5 to INPUT 8: mono balanced microphone or line signals, with

Euroblock 3-contact connector:

 Hot or direct signal > + Terminal
 Cold or inverted signal > − Terminal
 Earth >  Terminal

9

Note: if the sound source is stereo, and you want to connect it to one of the IN5 to

IN8 local mono balanced inputs on the eMIMO1616 unit, you can do it via the
following stereo to mono conversion, simply by using a pair of external resistors:

On the rear panel of the unit there is a PHANTOM ON/OFF switch, which allows the
provision of a phantom power supply to inputs 5 to 8 for use with microphones
(usually condenser microphones).

 In addition, there are 2 connection ports called PAGER A and PAGER B, with

INPUT 7 and INPUT 8 audio inputs (respectively) duplicated for use with
PAGER priority modules. These ports receive audio signals from eMPAGE
messaging consoles. A standard (crossover) CAT5 or higher cable, with an
RJ45 connector on each end, connects a messaging console point to point to
either of ports A or B on the unit, through which the remote DC supply for the
messaging console, control data, and balanced audio from the messaging
console microphone can be transmitted. The maximum number of messaging
consoles allowed is 2: one connected to the PAGER A port and the other to
the PAGER B port.

Once the physical connections for the various audio inputs have been made, it will
be necessary to adjust the GAIN control for each of them, in order to obtain a signal
of maximum intensity and maximum signal / noise ratio, so that they can be
correctly employed as sound sources for the installation. To that end it is necessary
to maximise the volume controls for the audio players, before adjusting the gain on
the eMIMO1616 unit. Use the level indicators on the front of the unit (physical VU
meters), and the virtual level indicators (on-screen VU meters) from the web
application in order to correctly adjust the gain, seeking to obtain signal peaks for
the zone of close to 0 dB (orange zone on the virtual VU meters) with peaks above
this (“red” zone, saturation or clipping) being the exception.

eMCONTROL1

CAT5

Pair of wall panels, on which eMCONTROL1 (right) receives the balanced

audio from its complementary panel, WpaMIX-T (left)

The eMIMO1616 has 8 control ports (REMOTE INPUTS) with RJ45 connector, for
the connection of eMCONTROL1 remote control panels. Each of these ports, in
addition to providing the DC power supply and digital communication bus for the
remote panels, has a balanced mono audio input with line level, taken as a remote
input for the eMIMO1616 unit. It is thus possible to increase the number of audio
inputs for the unit using these 8 remote inputs, in addition to the 8 local inputs
available via audio connectors on the rear panel of the matrix.

The connection of a balanced mono audio signal to a REMOTE port on the
eMIMO1616 matrix is made in the following way:

 Hot or direct signal > Terminal 8 on the RJ45 connector
 Cold or inverted signal > Terminal 7 on the RJ45 connector
 Earth > Terminal 6 on the RJ45 connector

In the event of using an eMCONTROL1 remote panel to control a zone of the
installation, the eMCONTROL1 panel itself has an internal connector to receive the
audio signal from an adjacent, complementary panel, such as the WPaMIX-T, on the
pair from the example below. This configuration type is ideal for remote control of
the zone and audio from the zone itself: a single CAT5 standard cable is connected
between the eMCONTROL1 panel and a REMOTE port on the eMIMO1616 unit, to
provide the DC power supply, transmit digital control data, and send remote audio
signals from a physical input on the eMCONTROL1 complementary panel to the
eMIMO1616 unit.

11

5.5. PAGER A, PAGER B connections and priority PAGER / DUCKER
modules

In the local inputs section on the rear panel there are 2 ports called PAGER A and
PAGER B, with audio inputs internally matching INPUT 7 and INPUT 8
(respectively).

The PAGER ports are used for point to point connection to 2 eMPAGE messaging
consoles, through which it is possible to perform functions such as real-time voice
calls (paging) to output zones within the installation, using a priority module on
the eMIMO1616 unit which fades or fully mutes the sound content of the existing
program in those zones at the time of the action.

A standard (crossover) CAT5 or higher cable, with an RJ45 connector on each end,
connects a messaging console point to point to either of ports A or B on the unit,
through which the remote DC supply for the console, control data, and balanced
audio from the messaging console microphone can be transmitted.

A maximum of 2 consoles is allowed; one connected to the PAGER A port, and the
other to the PAGER B port, with each one using a PAGER priority module on the
eMIMO1616 unit.

Note: it is it not possible to perform the following connections simultaneously,

and the connections listed below are mutually exclusive:

 a messaging console to the PAGER A port + an audio signal to the INPUT7

Euroblock connector

 a messaging console to the PAGER A port + an audio signal to the INPUT7

Euroblock connector

The total number of PAGER (to messaging console) or DUCKER (without
messaging console) priority modules for the eMIMO1616 is 4, assignable to the
local inputs 5 to 8. These 4 modules may be activated or deactivated, and each of
them may use one of the 2 available priority levels, so that the signals with greater
priority will fade the program signal selected in the destination zone, in addition to
the signals of lesser priority sent to these zones, if there are any, at the time when
the maximum priority module is activated.

12

See the eMIMO1616 web application manual to find out more about programming
the PAGER / DUCKER priority modules.

5.6. REMOTE INPUTS 1 to 8 connections

On the eMIMO1616 rear panel there are 8 control ports, REMOTE INPUTS 1 to 8,
which are enabled for the connection of eMCONTROL1 zone control wall panels.
Each port has an RJ45 connector, and each eMCONTROL1 panel also has an RJ45
connector, such that the physical connection between a remote panel and a
REMOTE port on the eMIMO1616 unit can be made, point to point, via a CAT5
standard or higher (crossover) cable.

This physical connection provides a DC power supply to the remote panel from the
eMIMO1616 unit, and establishes a digital communication bus between the two
pieces of equipment. It also allows the reception of balanced mono audio from a
potential remote sound source (connected on the side of the control panel) on the
eMIMO1616 unit.

The wall control panels are configured by the Administrator user via the
eMIMO1616 web application (see web application manual for the eMIMO1616), so
that it is possible to fully disable them, or enable them to function as user controls
for an installation zone, including all or some of the following functions:

 Selection of sound source (program audio), from a customised list for each

panel that includes some local sources and/or the remote source itself.

 Volume adjustment (with a maximum and minimum adjustment margin) and

mute control

 Equalisation adjustment, with 3-band EQ (BASS-MID-TREBLE).

Alternatively, these inputs may receive, exclusively, a balanced mono signal via the
RJ45 connector, while respecting the corresponding assignation of pins (see
section 3.4):

 Hot or direct signal > Terminal 8 on the RJ45 connector
 Cold or inverted signal > Terminal 7 on the RJ45 connector
 Earth > Terminal 6 on the RJ45 connector

13

5.7. REMOTE PORTS, RJ45 interface pinout

 Pin 1: audio hot or direct signal
 Pin 2: audio cold or inverted signal
 Pin 3: ground
 Pins 4 & 5: digital data bus
 Pin 6: +12 VDC supply
 Pin 7: unused
 Pin 8: ground

5.8. Audio output connections

The eMIMO1616 has16 audio output channels (zone outputs), with independently
configurable balanced line, such as:

 mono outputs (1 channel per output)
 stereo outputs (2 channels per output, natural pairs, 1-2, 3-4, 5-6, etc.)

Each output has a 3-contact Euroblock connector,

 Hot or direct signal > + Terminal
 Cold or inverted signal > − Terminal
 Earth >  Terminal

In the event of connecting an output channel to an amplifier or audio device with
balanced input, it is recommended to connect terminals +, − and  point to point
between the two units. In the event of connecting an output channel to an amplifier
or device with an unbalanced audio input, do not connect the − terminal.

MONITOR output (marked with a headphones symbol): 3.5mm stereo mini-jack
connector with rotary level control to listen via headphones. It is particularly
useful for listening to output signals from the unit without disturbing its normal
operation. The selection of the signal to listen to is made via the front panel, simply

14

by pressing the “select” button for the zone you wish to monitor. The volume

control for the headphones signal is after the volume control for the zone, so that
the volume of the zone, or whether it is in MUTE, will have to be taken into
account.

5.9. ETHERNET and RS-232 ports for programming and control

The RJ45 ETHERNET connector on the rear panel allows the connection of the unit
to an Ethernet network, either directly to a computer or to another device with an
Ethernet interface, point to point. This connection enables, within a local network,
the following:

 The Programming and overall management of the eMIMO1616 unit via the

embedded web application and a standard web browser running on a
computer, a tablet, etc.

 The connection of client devices for the end user in installation zones via the

eMIMO pilot application, which is compatible with Android and iOS, or via
standard web browsers running on computers, tablets, etc.

 The connection of third-party equipment for integration within control

systems (Crestron®, Extron®, AMX®, Vity®, Medialon®, etc., brands
registered by their manufacturers), using the TP-NET protocol embedded in
the eMIMO1616. See the TP-NET protocol manual for further information.

The DB9 RS-232 connector on the rear panel allows the connection of the unit
point to point to a computer or other control device. This connection exclusively
uses the integration via series port with third-party equipment and control
systems (Crestron®, Extron®, AMX®, Vity®, Medialon®, etc., brands registered
by their manufacturers), using the TP-NET protocol embedded in the eMIMO1616.
See the TP-NET protocol manual for further information.

The parameters necessary for a correct series connection are the following:

 Baud rate: 115200 (fixed, no autonegotiation)
 Data bits: 8
 Parity: None
 Stop bits: 1

15

 Flow control: None

5.10. MUTE port

The eMIMO1616 has a control input, or MUTE port, on the rear panel, which allows
the enabling / disabling of mute for audio outputs (zones) from the unit via a
button, relay or the closing of an external potential-free contact.

The allocation of outputs affected by the MUTE port is set via the eMIMO1616 web
application. See the eMIMO1616 web application manual for further information.

6. CONFIGURATION AND CONTROL

6.1. Configuration via embedded web application

Once the physical connections have been made, the eMIMO1616 must be
configured via the embedded web application, from a computer, tablet, or similar
device on which it is possible to open a standard web browser, connected to the IP
address of the unit (by default 192.168.0.100, but may be changed). This task is
reserved exclusively for the system installer or Administrator, who must be
identified by “admin” user credentials:

16

See the eMIMO1616 web application manual for full information regarding
configuration of the unit.

Note: the eMIMO1616 has an information screen which is activated by pushing and

holding simultaneously (>3 seconds) the CTRL key and the encoder on the front
panel:

The screen shows the following information:

 Firmware version being used by the unit
 NAME: name of the eMIMO1616 unit
 Network connection parameters: IP address, subnet mask and network

gateway

 Bank1: memory bank in use (1 or 2). Useful information for the detection of

and solution for various problems with the unit

 Admin: number of admin users connected to the unit (0 or 1)
 Users: numbers of client users, via the eMIMO pilot application or web

browsers (0 to 20)

The main parameters, settings and functions which are accessible on the
eMIMO1616 from its web application are:

 General configuration; unit name, network parameters, recording and

recovery of projects (overall equipment configuration), start mode, firmware
updates, default parameter reset, connection status, etc.

17

 Management of user accounts, which will allow access to external clients

(end users) via the eMIMO pilot application or web browsers: names,
passwords and enabled / disabled status

 Front panel parameters:

o adjustments to LCD screen: brightness, contrast, stand-by mode
o overall access / blocking (for all front controls)
o individual access / blocking for specific controls, and for specific

output zones. It is possible to allow access to the settings for some
zones and block them for others, or even decide which parameters
are accessible for each of them: volume adjustment and MUTE
and/or selection of sound source and/or equalisation via 3-band EQ
(BASS-MID-TREBLE)

 Local and remote audio input parameters; names, polarity, volume, MUTE,

equalisation via 3-band EQ (BASS-MID-TREBLE), noise gate, high-pass filter,
etc.

 Parameters for audio output (zones): names, mono / stereo mode, polarity,

selection of sound source, volume, accessible volume range for end users
(maximum and minimum levels), MUTE, equalisation via 3-band EQ (BASS­MID-TREBLE), noise gate, high-pass filter, effect of MUTE port activation
(closing of external contact), etc.

 Configuration of the 4 PAGER / DUCKER priority modules (with eMPAGE

messaging consoles / activated via audio level detection on the input in
question, respectively)

 Configuration of the eMCONTROL1 physical control panels connected to the

eMIMO1616 unit; connection status, enabled / disabled status; zone under
control, enabled functions (volume adjustment and MUTE and/or selection
or sound source and/or equalisation via 3-band EQ (BASS-MID-TREBLE), etc.

 Creation, edition and configuration of the pilot panels, accessible from

external devices via the eMIMO pilot application or web browsers: public or
private panel (accessible only for specific users), enabled / disabled status,
zone under control, enabled functions (volume adjustment and MUTE and/or
selection or sound source and/or equalisation via 3-band EQ (BASS-MID­TREBLE), graphical appearance (control types, slider or rotary, control
colours, texts and background), etc.

6.2. Front panel control

Using the physical controls on the front panel of the eMIMO1616 it is possible to
make adjustments to the various output zones from the unit. The settings available
for the various zones will be those that the admin user enabled via the web
application, and may range from blocking the entire front panel to complete

18

freedom to control all zones (volume adjustment, source selection and equalisation
adjustment), or the total or partial blocking of some of them.

Pressing a SELECT key corresponding to one of the outputs on the unit allows it to
be controlled via the CTRL key, the encoder and the LCD screen on the right of the
front panel. In addition, the LED indicator on the SELECT key pressed will flash
with a fixed rhythm (long off, short on), indicating that the output has been
selected for control. After a few seconds without changing the front controls, in
other words, without making any adjustments, the key will stop flashing.

Example pressing the SELECT key for output 1 or 2 (the same effect in this case, at
they are set as a stereo pair):

Example pressing the SELECT key for output 3:

In the upper images you can see:

 2 level indicators or VU meters (vertical bars): the one on the left of the

screen shows the level of the sound sources selected for the selected zone
(pre-fader), and the one on the right shows the level of the output signal for
the zone (post-fader)

 First line of text: output number (zone) selected
 Second line of text: name (tag) for the selected zone
 SRC: selected sound source
 VOL: set output volume

The flashing box above SRC or VOL, in addition to the line of text in bold on a light
background, indicate which function is at that moment focussed, or ready for

19

setting. The lower image shows the VOL control, which allows adjustment of the
output volume via an encoder, and within a predefined range (set by the admin
user) for the selected output:

On the screen, a long press (>3 seconds) of the encoder, or a long press of the
SELECT key enables / disables the MUTE function for the zone in question:

Note: on the muted outputs (MUTE function enabled):

 A muted output, not selected for adjustment, will have its SELECT/MUTE key

lit continuously (no flashing)

 A muted output which is at the same time selected for adjustment, will have

its SELECT/MUTE key flashing with a fixed rhythm, but opposite to the
rhythm of an unmuted output selected for adjustment

Pressing the CTRL key quickly changes the focus to the other available function, in
this case, to the SRC function, or the sound source selection:

Then, turning the encoder allows the selection of one of the available sound
sources, with confirmation of selection by pressing the encoder:

A long press of the CTRL key jumps to the equalisation screen for the zone:

20

On the screen, the selected tone control is indicated by the flashing rectangle
around the text BASS, MID or TREBLE, and adjustment is carried out by turning the
encoder:

Short presses of the CTRL key allow another equalisation control to be highlighted:

Another long press of the CTRL key, or a period of inactivity of 10 seconds, returns
the screen to its previous status, showing main data for the zone under control:

All the previously described controls for the specific zone (VOL, SRC, BASS, MID
and TREBLE) will be shown and available for adjustment only if the admin user
has enabled the front panel for this, and a zone may be partially or fully blocked for
