4. INTRODUCTION

Ecler WiSpeak is a technology that provides Wireless Professional Audio for fixed
(permanent or temporary) installations, including transmitter devices and receiver
(loudspeakers) devices.

The main highlights of the WiSpeak technology are:

 Simple and fast installation (with or without the use of the WiSpeak grip app)

 Plug & play: no wires, no construction works
 The receivers just need to get mains AC, usually from the already existing

lighting rails. They integrate an internal universal Power Supply (100-240VAC ­50-60Hz)

 Solid and stable wireless transmission protocol, robust against audio drops
 Up to 500 m2 coverage (depending on the location of the transmitter and the

receivers, and the obstacles in between them)

 Master volume control and individual loudspeaker volume control, allowing for

audio level zoning

 WiSpeak grip app available for Android and iOS, for the setup and advanced

tuning of the system (Admin profile), as well as for the end user simple control
(User profile)

 Scalable: daisy-chain option from one receiver to a new transmitter, or from one

transmitter to a second transmitter, to extend the total amount of loudspeakers
and the area coverage

6

 Compatible with Eutrac and Global Track Pro lighting rail standards

A WiSpeak installation is typically made up of one transmitter device and from 1, up to a
maximum of 24 receiver units, where:

 the transmitter device is the electronic unit that communicates with all the

receiver devices to create a WiSpeak wireless network, and takes the role of the
Master unit in it

 the receiver units are self-powered loudspeakers with wireless audio reception

and control capabilities, under the control of the Master unit

The Master unit has these main functions:

 to pair (link) and keep a stable communication with all the receiver units in the

system – when paired and within the valid wireless coverage range - supervising
the connection quality of them all

 to take care of the global configuration of the system (audio inputs in use,

equalisation, levels, etc.)

 to send the individual configuration commands to each receiver unit, as each

receiver can have customised parameters

 to send audio contents to all the receiver units, keeping a perfect synchronisation

among them all (<6ms latency and <1μs jitter)

7

6. INSTALLATION

6.1. TUBE receivers mounting and power up

The TUBE receivers come with the lighting rail bracket already mounted.

Follow these steps to install a TUBE unit in a lighting rail:

1. Ensure that the 4-position (OFF-1-2-3) circuit selector wheel in the TUBE unit is

in the OFF position

2. Insert the loudspeaker in the lighting rail, as shown in the image

Connection to a GLOBAL Trac Pro / Eutrac lighting rail (three-circuit lighting track system)

11

3. Rotate the safety lug to secure the loudspeaker on the lighting rail. Rotate the

circuit selector wheel to a position other than OFF, the one matching with a
circuit in the rail that will deliver mains AC to the unit. Then, the safety lug will be
locked

4. Check whether the unit is really powered ON or not by watching the LED

indicators at its back panel: depending on the status of the receiver unit (at
factory defaults, already paired, etc) blinking or fixed lit LEDs will appear.

Both LEDs OFF permanently will mean that the unit is not powered, probably not
getting mains AC from the lighting rail. In this case, please check:

o The lighting rail is really powered with mains AC
o The TUBE receiver circuit selector wheel is in the right position. Check the

rest of positions to try to get a valid one, with some LED activity, thus
getting mains AC from the rail tracks

5. Orient the loudspeaker to obtain the required position on the vertical and

horizontal axes

Note: in case you want to install a TUBE receiver on a surface, where there is no

available lighting rail, you may want to use the optional surface mount accessory, ref.
TUBE SMA:

In first place, mount and power the accessory with mains AC. Then, follow the previous
steps to insert and fix the TUBE unit in it.

12

6.2. CUBE receivers mounting and power up

The CUBE receivers come with a lighting rail bracket already mounted, but they also
include a wall / surface mount bracket that can replace the lighting bracket in case that a
wall mount is the chosen option.

A CUBE unit could be as well installed directly on a surface, like a desktop, shelf, table,
etc, without using the rail mount or the wall mount included brackets. To do so, the
supplied self-adhesive rubber legs can be attached to the unit’s bottom face, and the
connection to a standard AC plug can be performed using the supplied additional AC
cord.

Follow these steps to install a CUBE unit in a lighting rail:

1. Ensure that the 4-position (OFF-1-2-3) circuit selector wheel in the CUBE unit is

in the OFF position

2. Insert the loudspeaker in the lighting rail, as shown in the image

Connection to a GLOBAL Trac Pro / Eutrac lighting rail (three-circuit lighting track system)

13

3. Rotate the safety lug to secure the loudspeaker on the lighting rail. Rotate the

circuit selector wheel to a position other than OFF, the one matching with a
circuit in the rail that will deliver mains AC to the unit. Then, the safety lug will be
locked

4. Power ON the unit by means of the back panel ON/OFF switch. Check whether

the unit is really powered ON or not by watching the LED indicators at its front
grill: depending on the status of the receiver unit (at factory defaults, already
paired, etc) blinking or fixed lit LEDs will appear.

Both LEDs OFF permanently will mean that the unit is not powered, probably not
getting mains AC from the lighting rail. In this case, please check:

o The lighting rail is really powered with mains AC
o The CUBE receiver circuit selector wheel is in the right position. Check

the rest of positions to try to get a valid one, with some LED activity, thus
getting mains AC from the rail tracks

o ON/OFF switch is in ON position and AC cable is connected

5. Orient the loudspeaker to obtain the required position on the vertical and

horizontal axes

14

Follow these steps to install a CUBE unit on a wall:

1. Drill three 6 mm holes in the wall, matching the position of the holes in the bracket.

2. Insert three 6 mm wall plugs into them.

3. Place the wall bracket in place, previously passing the supplied AC cable (if

required) through the square hole in the bracket. Attach the bracket to the wall.

4. Place the speaker in its final position by sliding it vertically downward so that the

guide on its back side matches the guide on the bracket.

5. Fasten the safety guide at the back of the mount (as shown in the diagram).

6. Orient the loudspeaker to the desired position on the vertical and horizontal axes.

Tighten the Allen screws on the bracket to fix this position on both axes.

7. Power ON the unit by means of the back panel ON/OFF switch.

15

6.3. CORE transmitter installation

Max: 24 receivers

Master

12

Máx: 12 meters

(transmitter)

A CORE transmitter unit is necessary to control and feed with wireless audio a WiSpeak
network of TUBE and/or CUBE receivers, up to a maximum of 24 units.

The CORE unit is suitable for installation on a wall or under a surface (table, shelf,
cupboard, etc.), thanks to its design and layout of its connectors, controls and LED
indicator lights. As it is a wireless transmitter device, it is very important to carefully
study and decide the physical location of the transmitter and the receiver units in the
venue.
Please, follow the following guidelines to decide a location for the CORE unit that can
get the best of a WiSpeak system in any venue:

 Take into consideration that the maximum RF operating scope from the CORE

unit to any receiver unit (TUBE or CUBE) is 12 meters, with direct line of sight.
This distance or shorter, with no obstacles in between both units, is required to
try to ensure the maximum connection quality and stability possible

 To get the maximum coverage area in a certain space, the location of the

transmitter unit (or Master unit) should be, ideally, as much centred as possible
in respect to the receivers’ network

Example 1: the transmitter is at the centre of a perimeter disposition of

receivers

16

Max: 24 receivers

Master

Máx: 12 meters

(transmitter)

Example 2: the transmitter is close to a corner in a rectangular space, to be

covered with WiSpeak receivers

In the second example, the maximum coverage area will be around ¼th of the
maximum coverage area in the first example

Once decided its location, the CORE transmitter must be fed with up to 3 audio inputs:

 INPUT 1: stereo balanced, Euroblock connectors (rear panel)
 INPUT 2: stereo unbalanced, RCA connectors (rear panel)
 INPUT 3: stereo, received via Bluetooth®, class 1 / up to 25 metre range (front

panel antenna)

17

Note: INPUT 3 (Bluetooth®, class 1) and, especially, INPUT 1 (analogue, balanced)

are suitable options to use when the transmitter unit is tried to be located as much
centred as possible in respect to the loudspeakers (for instance, on the ceiling of a
retail store, a restaurant or a corporate room), with the aim to get the maximum
coverage are possible. Both options allow sending audio from the music source
(audio player) to the transmitter over long distances, which would be necessary in
some cases, where it’s not possible to have booth devices close to each other.

For each channel (left or right) of the balanced input, INPUT1, the wiring is as follows):

Hot or direct signal > + terminal

Cold or inverted signal > – terminal

Ground >  terminal

The AUX OUT connection is available to connect external audio systems, like subwoofer
reinforcement loudspeakers, mixers, amplifiers, matrices, etc. By default, this output will
deliver exactly the same audio signal as the one sent to the receivers’ network, but this
can be modified using the WiSpeak grip app.

When all the connections are made, it’s time to power up the transmitter using the
included external power supply, connected to the DC IN terminal at the rear panel, and
start the WiSpeak setup process.

18

6.4. Disassembling WiSpeak receivers from lighting rails installations

Before detaching the WiSpeak receiver, ensure that the 4-position (OFF-1-2-3) circuit
selector wheel is set in the OFF position.

19

7. PAIRING THE RECEIVERS & STARTING UP THE WiSpeak SYSTEM

When a CORE transmitter is powered up for the very first time (or after a Factory
Defaults reset has been applied to it), it will show the WiS LED permanently lit ON and
the RX LED quickly blinking.

This LED code means that the CORE unit is ready to be paired to a network of receivers,
TUBE and/or CUBE models, up to a maximum of 24 of them.

Note: before stating a pairing procedure, it’s extremely important to check that

the CORE transmitter and every single TUBE or CUBE receiver are them all
powered ON and within the coverage range of the WiSpeak system. Otherwise,
a Partial Pairing result can be achieved (See chapter 9 for further information)

The paring process is as follows:

1. Make a short press on the recessed WiS PAIR key, using a small screwdriver

or pin tool for that

2. The Discover process, or scan for available receivers, will start. Both LED

indicators (WiS and RX) will blink together (not alternately) during the time it
takes to finish it (the full procedure can take several seconds to finish
completely)

3. When it’s over, and the network connections have been stabilised, both LEDs

will stay permanently lit, with no blinking. This means that a valid pairing
process has been performed, and a solid WiSpeak network exists between
the transmitter and from 1 to a maximum of 24 receivers

See chapter 9 for further information about the WiSpeak pairing system and procedure.

20

Once the pairing process is over and successful, the system is ready to be used:

 Press the SELECT key to select which audio source, from the 3 inputs available,

will be the selected one to be sent and played by the receivers’ network.
A dedicated LED for each input will turn ON when it is selected. When the
Bluetooth input is selected, its blue LED will remain permanently lit when there’s
a Bluetooth emitter paired and correctly connected to it, and will blink when
there is not

 Gesture the VOLUME knob to adjust the Master (general) volume of the

installation. A short press of the same knob will activate / deactivate the MUTE
function of the system (meanwhile MUTE is ON, Volume can’t be modified)

Note: the Bluetooth® audio input needs a standard Bluetooth® pairing process

from the audio player (smartphone, tablet, computer, etc.) to the CORE
transmitter. The Bluetooth® ID and pairing code are available in the CORE
transmitter Model / Serial Number label.

The above process provides a solid “plug&play” method to easily set a system up and
running in few minutes, with no need to use the WiSpeak grip app. However, WiSpeak
grip provides the installer of the system with many additional fine-tune options that can
lead to a system’s more precise performance, better yet customised to each venue and
end user profile requirements. WiSpeak grip also can provide a very simple control
screen for end users, just including a general volume control and audio source selection,
both under the limits specified by the Admin (installer).

See WiSpeak grip app user manual for further information.

21

8. CORE transmitter VOLUME control: REMOTE and MUTE control ports

The CORE transmitter includes two audio control interfaces at its back panel:

 MUTE port, Normally Open, Euroblock 2 pin connector: it allows to connect an

external dry contact circuit (relay, switch, etc.) that, when closed, will MUTE the
WiSpeak wireless audio transmission, as well as the audio delivered at the AUX
OUT back panel connector. It is a very useful way of silencing the WiSpeak audio
system completely whenever an external emergency or alarm system, for
instance, must be activated

 REMOTE port, RJ45 connector: it allows connecting a WPaVOL or compatible

wall panel, providing the end user with a very simple volume control method,
and using a standard CAT5 cable to connect the wall panel to the CORE unit

The 3-positions VOL CTRL switch at the back panel of a CORE transmitter provides
these 3 volume control options:

 LOCAL & APP: at this switch position, the general volume of the WiSpeak

system can be controlled using the front panel VOLUME knob and the WiSpeak
grip app. Both methods can adjust the volume within the minimum and
maximum volume range that can be defined using the WiSpeak grip app (Admin
user) (*). The REMOTE VOLUME port is disabled in this position

 LOCKED: when the switch is set to this position, the volume control keeps the

current value and remains blocked. It can’t be modified again using any method,
unless the switch is set to a different position

 REMOTE: at this switch position, the volume can just be adjusted using the

WPaVOL wall panel connected to the REMOTE port. The CORE front panel
VOLUME knob and the WiSpeak grip app volume faders are then disabled in this

position (*)

(*) The general volume control, by any method used, can be limited within a given

minimum and maximum volume range, which can be defined using the WiSpek grip app

9.1 CORE transmitter

The front panel LEDs provide information about the working status of the unit and the
currently selected source.

 WiS / RX LEDs

At the left-hand side, there are two LED indicators that provide information
about the global status of the transmitter unit and its network of paired receivers:
WiS (WiSpeak interface status) and RX (receivers’ network status), with these
possible codes or combinations:

23

 INPUT1 / INPUT2 LEDs

o Permanently ON: IN1 or IN2 is selected, and its incoming audio signal is

sent via WiSpeak wireless audio transmission to the receivers’ network.
Short-press the SELECT key to modify the input selection

o Blinking (gain adjust mode): when IN1 or IN2 is selected (its LED is in

fixed ON condition), a long press (> 5 seconds) of the SELECT key will
get the unit into gain adjust mode. Rotate the front panel knob to adjust
an input’s gain:

 IN1 gain: 14 steps, each one increasing or decreasing with each

knob’s rotation step

 IN2 gain: 5 steps, each one increasing or decreasing with each

knob’s rotation step

A short press on SELECT key will exit the gain adjust mode.

 BLUETOOTH

input is selected, and there is an

external device (smartphone, tablet, computer, audio player, etc.)
connected to the CORE unit for audio transmission (A2DP). If a valid

media is played in this external device and transmitted via Bluetooth®, it
will be received by the CORE unit and sent via WiSpeak wireless audio
transmission to the receivers’ network

o Blinking: the Bluetooth® input is selected, but there is NOT an external

device (smartphone, tablet, computer, audio player, etc.) connected to
the CORE unit for audio transmission (A2DP). Therefore, even the

Bluetooth® input is selected in the CORE unit, no audio will be received
via Bluetooth® by the CORE unit, thus not sent via WiSpeak wireless
audio transmission to the receivers’ network

10. Extended information about the WiSpeak PAIRING PROCEDURE

The WiSpeak pairing procedure must be necessarily performed at least once to setup a
WiSpeak system, after the transmitter and all the receivers have been physically
installed and powered, and it’s time to set up and run the installation.

But it can be performed later again, for a second, third, or more times if needed, and due
to many possible reasons, like:

One or more TUBE / CUBE receivers have been added to the initial batch
One or more receivers have been removed
One or more receivers have been replaced by other units

… or, sometimes, because the last pairing process was not 100% satisfactory (we’ll
call it “Partial Pairing”)

The pairing procedure is accumulative, meaning this that:

 When the pairing procedure is done for the first time, it starts a Discover

process, or scan for available receivers. Both LED indicators (WiS and RX) will
blink together (not alternately) during the time it takes to finish it

 It ends up with a internal list in the transmitter containing the successfully paired

receivers

 When performed over again (for the second, third time, or further) it scans once

more to check whether those receivers already in the paired list are online or not,
and also tries to find out more available (new, unpaired) receivers. The list is then
increased including the new receivers successfully paired, but it will also log the
ones already paired in the past, but not successfully reached during the last scan,

if any (*)

(*) If that happens (one or more paired receivers in the past are not correctly reached

during a new pairing process), we’re facing a Partial Pairing result.

A Partial Pairing result will be displayed with the following transmitter’s front panel
LED code:

 WiS LED: blinking
 RX LED: blinking within a 3 seconds loop sequence. Every single blink that is

shown means that one of the paired receivers in the past is currently offline, or
not reached by the transmitter for any reason (it is powered OFF, or out of range,
or it is failing, etc.). Under this scenario, it is recommended to use WiSpeak grip
app for a proper troubleshooting.

27

Warning: in case a pairing procedure results in a Partial Pairing, a new pairing process

will be required, after having applied the proper countermeasures to try to pair again
and get a successful result. A WiSpeak system always needs a successful pairing
process to start performing in a stable and reliable way.

Please, apply countermeasures (check coverage distances, receivers and transmitter
power and integrity, etc.) and repeat the pairing procedures as many times as necessary
to finally end up with a successful pairing status.

11. UNPAIR PROCEDURE

Whenever a system needs to be restored back to an “unpaired” status (to start the

installation from scratch, to reuse the hardware units in a different environment, etc.),
the following steps must be followed:

 Check that the transmitter is powered ON
 Check that each and every single receiver paired to it is as well powered ON
 Check that both the transmitter and all the receivers paired to it are performing

correctly (see chapter 8 for further information)

 Press and hold the WiS PAIR recessed key, with a small screwdriver or pin tool,

for more than 5 seconds

 WiS and RX LEDs will start blinking alternately for some seconds, until the

unpair process finishes

After a successful unpair procedure:

 WiS LED should remain lit ON and the RX LED should blink quickly in the

transmitter, meaning this that the transmitter unit is ready to be paired to a
network of receivers, up to a maximum of 24 of them

 WiS LED and STR LEDs will both blink in each receiver, meaning this that the

unit is not paired to any transmitter and it is available to be paired to a
transmitter

(*) Note: when it happens that one TUBE or CUBE receiver is not in these

conditions (powered ON, paired and online with its Master transmitter), the unpair
procedure conducted by the transmitter, and described above, will be unable to
unpair that particular receiver unit. In this case, the alternative method of unpairing a
receiver is by pressing and holding its rear panel UNPAIR key for 5 seconds, starting
its own unpair process. It will end up with its WiS LED and STR LEDs blinking,
meaning this that the unit is not paired to any transmitter and it is available to be
paired to a transmitter

28

12. SPECIAL RESET PROCEDURES

Sometimes it will necessary to reset the transmitter / receiver units to their factory
defaults, or perhaps just the Bluetooth® module to its factory defaults as well.

As both procedures are extremely dangerous for a running WiSpeak system when
applied without the proper permissions, and/or without the right knowledge of their
consequences, we beg you ask your official WiSpeak installer / distributor to carry them
out.

13. CLEANING

The casing should not be cleaned with solvents or abrasive materials since they can
damage the screen printing. To clean the product, please used a cloth dampened with a
mild liquid detergent and water, and wipe it off with a dry and clean cloth. Be careful
that water never gets into the unit through its holes.
