INTRODUCTION
ED point source systems are designed for indoor and outdoor sound reinforcement applicaons ranging from clubs, bars and
restaurants to theatres, live music venues, houses of worship and theme environments. The ED150A is a powered loudspeaker
system able to deliver consistently repeatable performance due to the PROEL CORE digital signal processing and the integrated
Class D amplier module.
The ED150A consists of an 15” LF drive unit and a 1.4” HF compression driver loaded by an asymmetric HF horn in a compact
enclosure, designed for many mul-purpose sound reinforcement acvies. The asymmetric HF
coverage paern, varying from 100° horizontal in the lower part of the horn for more eecve
near eld coverage, and narrowing to 60° horizontal at the top of the horn for more focused
coverage in the far eld. The result is more accurate coverage of a typical auditorium than is
possible with a xed horizontal coverage device. The HF horn is also rotatable through 90° by
simply removing four screws and realigning the horn, so that coverage can also be opmised
for stage monitor use. This rotatable horn feature also makes it possible to maintain the ideal
coverage paern when the cabinet is installed in a horizontal (landscape) orientaon. Its
asymmetric dispersion paern provides opmal coverage of typical rectangular venues, with
wider dispersion at the front and narrower dispersion at the rear.
This versale loudspeaker can also be used as a low prole stage monitor with its 35° tapered
side, and in this situaon the HF horn can be rotated to maintain the best coverage paern for
performers both near to and further away from the monitor. ED150A cabinet is an unobtrusive
and compact format designed for a multude of near eld applicaons such as theatre under-
balcony ll, stage front ll, delay speaker, bar and restaurant audio, and discreet stage monitor.
A pole mount socket make this a very versale loudspeaker in both portable and permanently
installed applicaons.

I/O AND CONTROL OPERATIONS
MAINS IN
Powercon® NAC3FCA power input connector (blue). To switch the amplier on, insert the Powercon®
connector and turn it clockwise into the ON posion. To switch the amplier o, pull back the switch
on the connector and turn it counter-clockwise into the POWER OFF posion.
MAINS OUT
Powercon® NAC3FCB power output connector (grey). This is connected in parallel with the MAINS
~ / IN. The maximum load applicable depends on the mains voltage. With 230V~ we suggest to
link a maximum of 5 ED120A loudspeakers, with 120V~ we suggest to link a maximum of 3 ED120A
loudspeaker.
WARNING! In the case of product failure or fuse replacement, disconnect the unit
completely from the mains power. The power cable must only be connected to a socket
corresponding to the specicaons indicated on the amplier unit.
The power supply must be protected by a suitably rated thermo-magnetic breaker.
Preferably use a suitable switch to power on the whole audio system leaving the Powercon®
always connected to each speaker, this simple trick extend the life of the Powercon®
connectors.
INPUT
Audio signal input with locking XLR connector. It has a fully electronically balanced circuitry
including AD conversion for the best S/N rao and input headroom.
LINK
A direct connecon from the input connector to
link other speakers with same audio signal.
ON
This LED indicates power on status.
SIGN/LIMIT
This LED lights in green to indicate the presence
of the signal and lights in red when an internal
limiter reduces the input level.
GND LIFT
This switch li the ground of the balanced audio inputs from the earth-ground
of the module.
NETWORK IN/OUT
These are a standard RJ45 CAT5 connectors (with oponal NEUTRIK NE8MC RJ45 cable connector carrier), used for PRONET network
transmission of remote control data over long distance or mulple unit applicaons.
TERMINATE
In a PRONET network the last loudspeaker device must be terminated (with an inner load resistance) especially in a long run cabling:
press this switch if you want to terminate the unit.

PRESET BUTTON
This buon has two funcon:
1) Pressing it while powering on the unit:
ID ASSIGN the internal DSP assigns a new ID to the unit for the PRONET AX remote control operaon. Each loudspeaker must
have a unique ID to be visible in the PRONET network. When you assign a new ID, all the other loudspeakers with
the ID already assigned must be ON and connected to the network.
2) Pressing it with the unit ON you can select the DSP PRESET. The selected PRESET is indicated by the corresponding LED:
STANDARD Suited for a typical use of a standalone loudspeaker for any sound reinforcement situaon.
LOW CUT This PRESET is the same of the previous with an high pass lter (110Hz @ 48 dB/oct.) to use the loudspeaker in
combinaon with a subwoofer.
MONITOR Suited for the use of the system as a stage monitor, in this preset the deep lows are aenuated in order to
compensate the oor poson, the mid-low frequencies are enhanced for a beer presence and the mid-high
frequencies are reduced for an improved feedback rejecon.
USER This LED lights when the USER PRESET is loaded. This preset corresponds to USER MEMORY no. 1 of the DSP and,
as a factory seng, it’s the same to STANDARD. If you want to modify it, you have to connect the unit to a PC, edit
the parameters with PRONET AX soware and save the PRESET into USER MEMORY no. 1.
Note: see also the PRONET example further on this manual.

PRONET AX
PRONET AX soware has been developed in collaboraon with sound engineers and sound designers, in order to oer an “easy-to-
use” tool to setup and manage your audio system. With PRONET AX you can visualize signal levels, monitor internal status and edit
all the parameters of each connected device.
Download the PRONET AX app registering on MY AXIOM at the website at hps://www.axiomproaudio.com/.
The AXIOM acve loudspeaker devices can be connected in a network and controlled by the PRONET AX soware, for the network
connecon the USB2CAND converter oponal accessory is needed.
PRONET AX network is based on a “bus-topology” connecon, where the rst device is connected to the network input connector
of the second device, the second device network output is connected to the network input connector of the third device, and so
on. To ensure a reliable communicaon the rst and the last device of the “bus-topology” connecon must be terminated. This can
be done by pressing the “TERMINATE” switch near the network connectors in the rear panel of the rst and the last device. For
the network connecons simple RJ45 cat.5 or cat.6 ethernet cables can be used (please don’t confuse a ethernet network with a
PRONET AX network these are completely dierent and must be fully separated also both use the same kind of cable).

Assign the ID number
To work properly in a PRONET AX network each connected device must have a unique idener number, called ID. By default the
USB2CAN-D PC controller has ID=0 and there can be only one PC controller. Every other device connected must have its own unique
ID equal or greater than 1: in the network cannot exist two devices with the same ID.
In order to correctly assign a new available ID to each device for working properly in a Pronet AX network, follow these instrucons:
1. Switch o all the devices.
2. Connect them correctly to the network cables.
3. “TERMINATE” the end device in the network connecon.
4. Switch on the rst device keep pressed “PRESET” buon on the control panel.
5. Leaving the previous device switched on, repeat the previous operaon on the next device, unl the latest device is turned on.
The “Assign ID” procedure for a device makes the internal network controller to perform two operaons: reset the current ID; search
the rst free ID in the network, starng from ID=1. If no other devices are connected (and powered on), the controller assume ID=1,
that is the rst free ID, otherwise it searches the next one le free.
These operaons ensure that every device has it’s own unique ID, if you need to add a new device to the network you simply repeat
the operaon of step 4. Every device maintains its ID also when it is turned-o, because the idener is stored in the internal
memory and it is cleared only by another “Assign ID” step, as explained above.
With the network made always of the same devices the assigning ID procedure must be executed only the rst me
the system is turned on.
For more detailed instrucon about PRONET see the PRONET AX USER’S MANUAL included with the soware.
