INTRODUCTION
The SW18A is a high power compact subwoofer designed to partner ED series point
source loudspeakers for xed installaons in discotheques, nightclubs and bars, and
live music clubs, and for portable corporate audio-visual applicaons. It features
a high excursion 4” voice coil, 18” driver equipped with a double centred spider
that maintains linear voice coil travel even at high output levels. The phenolic birch
plywood cabinet is equipped with pole mount socket, stacking feet, ush handles,
and heavy duty wheels to enable easy handling and transportaon.
The SW18A subwoofer system is equipped with a high power 18” (460mm)
transducer capable of long excursion (up to 30mm peak-to-peak), controlled by
high sness Double Silicon Spider as centering suspension and by heavy duty
surround. The motor structure features high strength (BL²/Re) with opmized
symmetry and excursion controlled by Inner Flux Demodulang Ring. The robust
copper 100mm (4”) voice coil is wounded in two dierent layers both outside and
inside the coil support, then doubling the coil surface exposed to air cooling and
consequently improving the long term thermal capacity of the loudspeaker. Cones
are made of very high-sness glass ber reinforced paper, featuring also invisible
water repellent treatment.
The powered SW18A features an integrated 2000 wa class D amplier module
that provides convenience and simplicity of connection for portable sound
reinforcement applicaons, and also for xed installaons in discotheques and
live music clubs. It will deliver punchy bass performance from a very compact cabinet, and thanks to the integral pole mount socket partners well
with any of the ED series of point source loudspeakers in portable corporate audio-visual applicaons, while its small size enables it to be easily
ed into ght venue spaces.

CONTROL PANEL
ON - This LED indicates power on status.
PROT - This red LED lights when the amplier module is in protect mode for an internal
fault and, consequently, the amplier is muted.
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.
INPUT - Audio signal input with locking XLR connector. It has a fully electronically
balanced circuitry including AD conversion for the best S/N rao and input headroom.
LINK - A direct connecon from the input connector to link other speakers with same
audio signal.
GND LIFT - This switch li the ground of the balanced audio inputs from the earth-
ground of the amplier module.
PRESET BUTTON - This buon has two funcon:
1) Pressing it while powering on the unit:
ID ASSIGN the internal DSP assigns a new ID to the unit for the PRONET remote
control operaon. 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 This PRESET is suitable for any applicaon where low frequency
reinforcement is required. It features a 90Hz cut o frequency and
it can be used in almost any environment in combinaon with any
vercal arrays.
INFRA This PRESET can be used when a deeper bass response is required
(Note that when this preset is used the sound pressure level of the
system is slightly reduced). NOTE: INFRA and STANDARD PRESET
must NOT be used together in close units.
CARDIOID This special PRESET, combined with the STANDARD PRESET, gives the
advantage to reduce the low frequencies at the back of an array of three subs, in order to
obtain a more comfortable level for the performers on the stage without losing level for the
the audience in front of the array. The cardioid conguraon is also useful in situaon where
you want to reduce the bass frequency feedback due to many microphones on stage, for
example for acousc and jazz ensemble, classic orchestra, musicals. Further in this manual
you can nd some example how to set up a cardioid array.
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 seng, 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 soware and save
the PRESET into USER MEMORY no. 1.
NETWORK IN/OUT - These are a standard RJ45 CAT5 connectors (with oponal NEUTRIK NE8MC RJ45 cable
connector carrier), used for PRONET network transmission of remote control data over long distance or mulple
unit applicaons.
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.
POWER AMPLIFIERS
The SW18A is powered by DA SERIES digital power modules, a new generaon of CLASS D power amplier with digitally-controlled SMPS.
The innovave technology used for these ampliers (including also the use of a variable switching frequency) oers performances at the top of
the range, such as a superior sound denion at any audio frequency, very high dynamics also for low level signals and very low distoron even at
the maximum power The superior sound quality can be compared with top-of-the-range AB-class analog systems, while the DA modules feature
a higher dynamics, very compact size and light weight and eciency above 90%. The two DA modules employed for powering the SW18A deliver
in an ultra-compact package a maximum power of 4000W.
SIGNAL PROCESSING
The system processing is based on the CORE DSP plaorm, which has been designed by the PROEL R&D Laboratories using one of the most
advanced SHARC DSP for audio applicaon. It features 40bit, 96kHz oang point resoluon and high quality 24bit AD/DA converters, for a perfect
signal integrity, a dynamic range in excess of 110dB and a superior sonic performance. Thanks to its massive processing power, the CORE plaorm
is capable of providing the most sophiscated algorithms for speaker processing, together with remote control and networking capability.
The PRONET AX control soware, working on a solid and reliable CANBUS based network protocol, provides an intuive interface for the remote
control of the whole system, with the possibility of eqing, delaying, increasing the protecons and monitoring the status of the amplier.
PRONET AX
PRONET AX soware has been developed in collaboraon with sound engineers and sound designers, in order to oer 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 from the AXIOM website at hp://www.axiomproaudio.com/ clicking on downloads secon of the product.
The AXIOM acve loudspeaker devices can be connected in a network and controlled by the PRONET AX soware, for the network connecon the
PROEL USB2CAN (with 1-port) or the USB2CAN-D (with 2-port) converter oponal accessory is needed.
PRONET AX network is based on a “bus-topology” connecon, 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
communicaon the rst and the last device of the “bus-topology” connecon 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 connecons 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 dierent 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 idener 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 instrucons:
1. Switch o all the devices.
2. Connect them correctly to the network cables.
3. “TERMINATE” the end device in the network connecon.
4. Switch on the rst device keep pressed “PRESET” buon on the control panel.
5. Leaving the previous device switched on, repeat the previous operaon on the next device, unl the latest device is turned on.
The “Assign ID” procedure for a device makes the internal network controller to perform two operaons: reset the current ID; search the rst free
ID in the network, starng 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 operaons 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 operaon
of step 4. Every device maintains its ID also when it is turned-o, because the idener 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 instrucon about PRONET see the PRONET AX USER’S MANUAL included with the soware.
CARDIOID PRESET
The cardioid preset must be used in a sub array of three SW18A. Two box must be oriented towards the audience and one must be turned in the
opposite direcon (typically the box in the centre of the array). The boom and the top boxes must have the STANDARD PRESET, the box in the
middle must have the CARDIOID PRESET. The audio signal sent to all boxes is the same.
The CARDIOID PRESET has the same response of the STANDARD PRESET, but to obtain the maximum cancellaon on the back side of the array it
has the phase inverted and a proper level and delay seng.
The gure below shows two typical displacement of the array. The rst with all the boxes in horizontal posion for a total height of 1500 mm and
a width of 650 mm. The second one with all the boxes in vercal posion for a total height of 650 mm and a width of 1500 mm.
NOTES:
When placing the cardioid array keep a distance to walls or other obstacles of at least 80 cm (2.6 ) in order not to aect the radiaon of the
reversed cabinet.
When placing mulple cardioid arrays keep a distance between them of at least 140 cm (4.6 ) for vercal placement, or 100 cm (3.3 )for
horizontal placement, in order to maximize the combined radiaon of whole arrays.
