INSTALLATION AND CONNECTION

5.1. Location, mounting and ventilation

HUB1616/ HUB1408 has been specially designed to be placed in 19" rack structure,
occupying two units.

It is very important that, as a heat generating element, the unit is not completely enclosed
or exposed to extreme temperatures. Fresh air should be allowed to pass through the
ventilation holes in the chassis, leaving at least one free rack unit between each piece of
equipment and those installed above and below it in the rack frame.

If the installation consists of several units in the same rack or is carried out inside cabinets
closed by means of doors, it is highly recommendable to equip them with forced upward
ventilation, installing fans at their lower and upper ends. This upward flow of ventilation
will favor the dissipation of the heat generated in its interior.

5.2. Mains connection and power on

HUB1616/ HUB1408 operates on alternating voltages from 90 to 264V and 47 to 63Hz.
This device is equipped with an oversized power supply capable of adapting without any
type of adjustment to the mains voltage of any country in the world.

On the rear panel, next to the IEC power connector, there is an on/off switch for the unit.
On the front panel there is a LED ON indicator that illuminates when the unit is in
operation.

Do not allow the network cable to run parallel to the shielded cables carrying the audio
signal, as this may cause humming.

9

5.3. Local audio input connections

HUB1616 has 8 local audio inputs on its rear panel, HUB1408 has 6 local inputs, with the
following types of connections available:

Figure 1: HUB1616 local inputs

Figure 2: HUB1408 local inputs

• HUB1616: INPUT1 to INPUT4; HUB1408: INPUT1 and INPUT2: unbalanced

stereo line signals with double connector format (RCA and Euroblock). Use one or

the other connector, depending on the type of wiring available between your sound
source and the HUB unit:

o Dual RCA Connector: Connect your stereo sound source (CD players,

Smartphones, radio tuners, streaming players, etc.) directly using a cable
that delivers the left (L) and right (R) channels to the unit's white and red
RCA connectors, respectively.

o Euroblock connector, 3-pin: connect your stereo sound source this way:

▪ Left channel > Terminal L
▪ Right channel > Terminal R
▪ Ground > Terminal ⊥

• HUB1616: INPUT5 to INPUT8; HUB1408: INPUT3 to INPUT6: Microphone or line

signals, mono and balanced, with 3-pin Euroblock connector:

▪ Live or direct signal > Terminal +
▪ Cold or inverted signal > Terminal -
▪ Ground > Terminal ⊥

10

Note: If your sound source is stereo, and you want to connect it to one of the local inputs

IN5 to IN8 of the HUB1616 unit (local inputs IN3 to IN6 in HUB1408), mono and
balanced, you can do it by means of the following stereo to mono conversion, only using
a pair of external resistors:

Figure 3: stereo to mono conversion

On the rear panel of the unit there is a PHANTOM ON/OFF switch, which provides
phantom power to inputs 5 to 8 on the HUB1616, inputs 3 to 6 on the HUB1408, for use
with microphones that require it, usually condenser microphones.

• Additionally, there are 2 connection ports called PAGER A and PAGER B, with audio

inputs INPUT7 and INPUT8 (respectively) on HUB1616, inputs INPUT5 and
INPUT6 on HUB1408, duplicated for use with PAGER priority modules). These
ports receive audio signals from eMPAGE type call stations. A standard CAT5 cable
(uncrossed) or higher, with RJ45 connector on both ends, connects a calling station
point to one of the unit's A or B ports, running through it the station's remote DC
power, control data and balanced audio picked up by the station's microphone. The
maximum number of stations allowed is 2: one connected to port PAGER A and/or
the other to port PAGER B.

Once the physical connection of the different audio inputs has been made, it will be
necessary to act on the GAIN controls of each one of them to obtain an optimum signal
intensity and maximum signal/noise ratio, so that they can be used correctly as sound
sources in the installation. Try to maximize the volume controls of the audio players before
adjusting the gain in the HUB unit. Use the level indicators on the front of the unit (physical
VU meters), as well as the virtual level indicators (on-screen VU meters) of the HANGAR
web application for the correct gain adjustment, trying to work normally with signal peaks
in the area close to 0 dB (orange area in the virtual VU meters) and very exceptionally
above it (“red”, saturation or clip area).

11

5.4. Remote Audio Input Connections

The HUB1616 / HUB1408 has 8 control ports (REMOTE INPUTS) with RJ45 connector,
for the connection of eMCONTROL1 type remote control panels. Each of these ports,
besides providing DC power and establishing the digital communication bus with the
remote panels, has a mono audio input, balanced and with line level, considered a remote
input of the HUB unit. In this way, it is possible to expand the number of audio inputs of
the equipment with these 8 remote inputs, in addition to the local inputs available through
audio connectors on the rear panel of the matrix.

Figure 4: remote inputs (wall control panels)

Connecting a balanced mono audio signal to a REMOTE port of a HUB device is done as
follows:

• Live or direct signal > Terminal 8 of the RJ45 connector

• Cold or inverted signal > Terminal 7 of RJ45 connector

• Ground > Terminal 6 of RJ45 connector

If an eMCONTROL1 type remote panel is used to control an area of the installation, the
eMCONTROL1 panel itself has an internal connector to receive the audio signal from an
adjacent and complementary panel, such as the WPaMIX-T in the pair of the example
below. This type of configuration is ideal to have zone control and remote audio from the
zone itself: a single standard CAT5 cable, connected between the eMCONTROL1 panel
and a REMOTE port of the HUB unit, is used to carry out the exchange of DC power,
digital control data and remote audio signal, physically entered in the eMCONTROL1
complementary panel, to the HUB unit.

12

Figure 5: WPaMIX-T and eMCONTROL1 mounting

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

In the local input section of the rear panel there are 2 connection ports called PAGER A
and PAGER B, whose audio inputs correspond internally to the INPUT 7 and INPUT 8
inputs (respectively) on the HUB1616, INPUT5 and INPUT6 on the HUB1408.

Figure 6: PAGER/DUCKER ports on HUB1616

The PAGER ports are used for point-to-point connection to eMPAGE-type call stations,
through which it is possible to carry out real-time voice call (paging) actions to exit areas
of the installation, using a priority module of the HUB unit that attenuates or completely
silences the sound content of the program existing in these areas at the time of the action.

A standard CAT5 cable (uncrossed) or higher, with RJ45 connector on both ends,
connects a calling station point to one of the unit's A or B ports, running through it the
station's remote DC power, control data and balanced audio picked up by the station's
microphone.

its companion panel, WPaMIX-T (left)

13

The maximum number of stations allowed is 2: one connected to the PAGER A port and/or
the other to the PAGER B port, each using a PAGER priority module in the HUB unit.

Note: The following connections cannot be made simultaneously, as they are

exclusive:

• a call station to the PAGER A port + an audio signal to the Euroblock connector of

the INPUT7 input on the HUB1616, INPUT5 on the HUB1408

• a call station to the PAGER B port + an audio signal to the Euroblock connector of

the INPUT8 on HUB1616, INPUT6 on HUB1408

The total number of PAGER (with call station) or DUCKER (without call station) priority
modules in a HUB device is 4, assignable to local inputs 5 to 8 in HUB1616, local inputs
3 to 6 in HUB1408. These 4 modules can be activated or not, and each of them can use
one of the 4 priority levels available, so that the signals with higher priority will attenuate
the program signal selected in the destination zones and also the signals with lower
priority sent to those zones, if they exist, when the module with maximum priority is
activated.

Refer to the HANGAR web application manual for programming the PAGER / DUCKER
priority modules.

5.6. REMOTE INPUTS 1 to 8 Connections

On the rear panel of a HUB device there are 8 control ports, REMOTE INPUTS 1 to 8,
enabled for the connection of eMCONTROL1 type zone control wall panels. Each port has
an RJ45 type connector, and each eMCONTROL1 type panel also has an RJ45 connector,
so that the physical connection between a remote panel and a REMOTE port of the HUB
unit is made, point to point, by means of a standard CAT5 or higher type cable (not
crossed).

Figure 7: remote audio inputs

14

This physical connection provides DC power to the remote panel from the HUB unit and
establishes the digital communication bus between the two units. It also implements
balanced mono audio reception from a potential remote sound source (connected on the
side of the control panel) in the HUB unit.

The control wall panels are configured by the user Administrator through the HANGAR
web application (see HANGAR web application manual), so it is possible to disable them
completely or to enable them to act as user control for a zone of the installation, including
all or some of the following functions:

• Sound source selection (program audio), from a customized list for each panel that

includes some local sources and/or the remote source itself

• Volume adjustment (with maximum and minimum operating range) and mute

control

• Equalization adjustment, with 3-tone control (BASS-MID-TREBLE)

Alternatively, these inputs can only receive a balanced mono audio signal via the RJ-45
connector, respecting the corresponding pin assignment (see section 3.4):

• Ground > Pin 6 of the RJ45 connector

• Cold or inverted signal > Pin 7 of RJ45 connector

• Live or direct signal > Pin 8 of RJ45 connector

5.7. Remote ports, RJ45 interface pins

• Pins 1 & 2: unused

• Pin 3: +12 VDC power supply

• Pins 4 & 5: data bus

• Pin 6: ground

• Pin 7: audio cold or inverted signal

• Pin 8: audio hot or direct signal

15

5.8. Output Audio Connections

HUB1616 has 16 audio output channels (zone outputs), 8 in HUB1408, with line level,
balanced and independently configurable as:

• mono outputs (1 channel per output)

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

Figure 8: HUB1616 zone outputs

Figure 9: HUB1408 zone outputs

Each output has a 3-pin Euroblock connector, with the following layout:

• Live or direct signal > Terminal +

• Cold or inverted signal > Terminal -

• Ground > Terminal ⊥

If an output channel is connected to an amplifier or audio device with a balanced input,
the + and - ⊥ terminals must be connected point by point and between the two devices.
When connecting an output channel to an amplifier or device with an unbalanced audio
input, leave the - terminal unconnected.

Figure 10: balanced audio output connection

16

MONITOR OUTPUT (marked with headphone symbol): 3.5mm stereo mini-jack connector
with a rotary level control for headphone listening. It is especially useful for listening to
the unit's output signals without disturbing its normal operation. The selection of the

signal to listen to is made through the front panel, simply by pressing the “select” button

of the zone you want to monitor. The headphone volume control is located after the zone
volume control and after the general volume control (GENERAL VOLUME), so you should
consider the zone volume and the general volume or, if the zone or general volume control
is set to MUTE.

5.9. ETHERNET and RS-232 programming and control ports

Figure 11: control ports

The RJ45-type ETHERNET connector on the rear panel allows the equipment to be
connected to an Ethernet network, or directly to a computer or other device with an
Ethernet interface, point-to-point. This connection enables, within a local network, the
following:

• Global programming and management of the HUB unit using the HANGAR

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

• Connection of client devices for end-user management of areas of the installation

through the Ecler pilot application, compatible with Android and iOS, or through
standard web browsers running on computers, tablets, etc.

• Connection of third-party devices for integration in control systems (Crestron®,

Extron®, AMX®, Vity®, Medialon®, etc., registered trademarks by their
manufacturers), using the TP-NET protocol embedded in the HUB devices. Refer
to the TP-NET protocol manual for more information.

The RS-232 type DB9 connector on the rear panel allows the connection of the point-to­point equipment to a computer or other control device. This connection is used only for
serial port integration with third party equipment and control systems (Crestron®,
Extron®, AMX®, Vity®, Medialon®, etc., registered trademarks of their manufacturers)
using the TP-NET protocol embedded in HUB devices. Refer to the TP-NET protocol
manual for more information.

17

The parameters required for a correct serial connection are as follows:

• Baud rate: 115200 (fixed, no auto negotiation)

• Data bits: 8

• Parity: None

• Stop bits: 1

• Flow control: None

5.10. MUTE port

The HUB1616 / HUB1408 has on its rear panel a control input, or MUTE port (Normally
Open = MUTE OFF / Closed = MUTE ON), which allows the activation / deactivation of the
mute of audio outputs (zones) of the unit by means of a push button, relay or external
potential free contact closure.

Figure 12: MUTE port

The assignment of outputs affected by the MUTE port is configured from the HANGAR
web application. Refer to the HANGAR web application manual for more information.

18

CONFIGURATION AND CONTROL

6.1. Configuration via embedded web application

Once the physical connections have been made, the HUB unit must be configured using
the integrated web application: HANGAR. It has to be configured from a computer, Tablet
or similar where a standard web browser is running, pointing to the unit's IP address,
which can be modified. This task is reserved exclusively for the installer or system
administrator, who must identify himself with his “admin” user credentials:

Figure 13: HANGAR, web application for configuration and control of HUB devices

Refer to the HANGAR web application manual for complete information about
configuring your computer using the built-in web server.

19

By default, the network configuration is in DHCP mode (dynamic IP address assignment).
Connection to a router/switch with DHCP server is required. To query the IP assigned to
the device, press and hold the CTRL and rotary encoder keys simultaneously for 3
seconds.

Figure 14: front panel LCD display and control keys

Note: HUB devices use the mDNS service to access them through a web browser on the

same local network (LAN). To do this, enter in the search bar of your browser:
device_name.local. By default, “hub1616.local” in HUB1616, “hub1408.local” in
HUB1408.

The configuration screen (CONFIG) shows the following information:

• Firmware version running on the unit

• NAME: name of the HUB unit

• Network connection parameters: IP address, subnet mask and network gateway

• Auto/Manual: IP assignment mode. AUTO: is in DHCP mode, the IP address

assignment is automatic. MANUAL: allows the configuration of manual network
parameters. Default:

o IP: 192.168.0.100

affected by the overall volume

• Configuration of the 4 PAGER / DUCKER priority modules (with eMPAGE type call

stations / activated by audio level detection on the input in question, respectively)

21

• Configuration of the eMCONTROL1-type physical control panels connected to the

HUB unit: connection status, enabled/disabled status, zone under its control,
enabled functions (volume adjustment & MUTE and/or sound source selection
and/or equalisation via 3-tone control (BASS-MID-TREBLE)), etc.

• Creation, edition and configuration of the pilot panels, accessible from external

devices through the Ecler pilot application or web browsers: public or private type
panel (accessible only by certain users), enabled/disabled status, area under its
control, enabled functions (volume & MUTE adjustment and/or sound source
selection and/or equalization through 3-tone control (BASS-MID-TREBLE)), graphic
aspect (slider or rotary control types, control colors, texts and background), etc.

6.2. Operation from the front panel

Using the physical controls on the front panel of a HUB device, adjustments can be made
to the different output zones of the unit. The settings available for the different zones will
be those enabled by the admin user from the HANGAR web application, and can range
from total blocking of the front panel to total freedom of control of all zones (volume
adjustment, source selection and equalisation settings), to total or partial blocking of some
of them.

Figure 15: HUB1616 front panel

Pressing a SELECT key corresponding to one of the unit's outputs takes control of the
unit using the CTRL key, the digital rotary control (hereinafter encoder) and the LCD
display on the right-hand section of the front panel. The LED on the SELECT key will also
blink at a fixed rate (long time off, short time on), indicating that the output has been
selected for control. After a few seconds without acting on the front controls, i.e. without
making any adjustments, this key will stop flashing. If the General Volume option has been
selected as the default zone selection, the display will show the controls for this after a
few seconds of inactivity. The HUB unit has this option enabled in the factory settings.

22

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

Example by pressing the SELECT key on output 3:

In the images above you can see:

• 2 level indicators or voumeters (vertical bars): the one on the left of the screen

indicates the level of the selected sound source for the selected zone (pre-fader),
and the one on the right indicates the output signal level of this zone (post-fader)

• First line of text: output number (zone) selected

• Second line of text: name (label) of the selected area

• SRC: selected sound source

• VOL: adjusted output volume

The flashing box over SRC or VOL, plus the line of text on light background and dark text,
indicates which function is currently in focus, or ready for adjustment. The image below
is of the VOL control, which allows the output volume to be adjusted by the encoder, and
within the predefined range (by the user admin) for the selected output:

In this screen, a long press (>3 seconds) on the encoder, or a long press of a SELECT key
activates / deactivates the MUTE function of the zone in question:

23

Note: about the muted outputs (active MUTE function):

• A muted output, and not selected for adjustment, will have its SELECT/MUTE

button permanently lit (not flashing)

• An output that is muted and at the same time selected for setting will have its

SELECT/MUTE key flashing at a fixed rate, but inverse to the rate that has an
unsilenced output selected for setting

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

The encoder then rotates to select one of the available sound sources, confirming its
selection by pressing the encoder:

A long press on the CTRL key allows you to go to the zone equalization screen:

Here, the selected tone control is indicated by the flashing box over the text BASS, MID
or TREBLE, and is adjusted by turning the encoder:

24

Short presses of the CTRL key allow another EQ control to be focused:

A new long press of the CTRL key, or a 10-second timeout, returns the display to its
previous state, showing the main data of the zone under control:

All the controls described above for a given zone (VOL, SRC, BASS, MID and TREBLE)
will be displayed and available for adjustment only if the admin user has enabled the front
panel to do so, and a zone may be completely or partially locked out for control from the
front panel.

When a particular function of a zone is disabled for adjustment from the front panel,
attempting to do so will result in the following message being displayed on the LCD:

When the front panel is completely locked (disabled) for use, pressing any key will result
in the following message on the LCD display:
