INTRODUCTION

The SW1800AV2 subwoofer is designed to deliver high quality low frequency reproduction where very high output is a key requirement, together with well defined deep bass and fast transient response, making it suitable for several different uses, ranging from touring applications to fixed installations and high-level dance clubs.
The SW1800AV2 is a very high quality powered subwoofer system featuring some of the most advanced technologies for low frequency reproduction. Its unique and innovative design is based on a configuration that can be defined as Manifolded Band Pass. It uses manifolding of the front side of the cones to maximize the mutual coupling between the two drivers, while loading the back of the cone with a large-size volume that has the function to create a path from the back of the transducers to the front. The  SW1800AV2 subwoofer system is equipped with two high power 18” (462mm) transducers capable of long excursion (up to 22mm peak-to-peak), controlled suspension and cloth surround with DAR (double asymmetric rolls) technology.
The robust copper 75mm (3”) voice coil is wounded around an aluminium support improving the long term thermal capacity of the loudspeaker. Cones are made of very high-stiffness reinforced paper, featuring also an advanced Autoclave waterproof cone treatment.
The SW1800AV2 is processed by 40bit floating point CORE2 DSP and powered by a high efficiency CLASS D amplifier module with a newly designed power supply equipped with PFC, which reduces the power consumption while enhancing reliability and consistency in all operating conditions. The innovative technology used for these amplifiers offers performance at the top of the range, such as superior sound definition at any audio frequency, very high dynamics for low level signals, and very low distortion  even at maximum power.

FUSE HOLDER
Here is where the mains protection fuse is placed.

WARNINGS:

• REPLACE THE PROTECTION FUSE ONLY WITH THE SAME TYPE: BUSSMANN MDA-15-R OR LITTELFUSE 326015.VX
• In the case of product failure or fuse replacement, disconnect the unit completely from the mains power.
• Use a suitable power cable and mains plug to build the power cable, it must only be connected to a socket corresponding to the specifications indicated on the amplifier unit. See assembly instruction downloadable from NEUTRIK WEB site at: http://www.neutrik.com/
• The power cable must only be connected to a socket corresponding to the specifications indicated on the amplifier 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.
• Connect no more units to the MAINS OUT connector than as specified above.
• Turn on each unit one a time starting from the latest unit.

ON
This LED indicates power on status.
PROT
This red LED lights when the amplifier module is in protect mode for an internal fault and, consequently, the amplifier 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 ratio and input headroom.

LINK
A direct connection from the input connector to link other speakers with same audio signal. GND LIFT
This switch lift the ground of the balanced audio inputs from the earth-ground of the amplifier module.

NETWORK IN/OUT
These are a standard RJ45 CAT5 connectors (with optional NEUTRIK NE8MC RJ45 cable connector carrier), used for PRONET network transmission of remote control data over long distance or multiple unit applications.

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 button has two function:

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 operation. Each loudspeaker must have a unique ID to be visible in the PRONET AX 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 application where low frequency reinforcement is required. The response starts at 45Hz and the cutoff is at 100Hz with LR 24dB/oct., use this preset for almost any application at ground stack.
   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), the response starts at 30Hz and the cutoff is at 60Hz with LR 24dB/oct., it must be used at ground stack only, alone or in combination with some other boxes set as STANDARD, absolutely do not use it in combination of CARDIOD preset.
   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 configuration is also useful in situation where you want to reduce the bass frequency feedback due to many microphones on stage, for example for acoustic and jazz ensemble, classic orchestra, musicals. Further in this manual you can find some example how to set up a cardioid array.
   USER
   This PRESET corresponds to USER MEMORY no. 1 of the DSP and, as a factory setting, 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 software and save the PRESET into USER MEMORY no. 1.

WARNING! SW1800AV2 is NOT designed to be suspended, use it in ground stack only.

PRONET AX
PRONET AX software has been developed in collaboration with sound engineers and sound designers, in order to offer an “easy-touse” 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 https://www.axiomproaudio.com/.
The AXIOM active loudspeaker devices can be connected in a network and controlled by the PRONET AX software, for the network connection the USB2CAND (with 2-port) converter optional accessory is needed.
PRONET AX network is based on a “bus-topology” connection, where the first 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 communication the first and the last device of the “bus-topology” connection must be terminated. This can be done by pressing the “TERMINATE” switch near the network connectors in the rear panel of the first and the last device. For the network connections 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 different and must be fully separated also both use the same kind of cable).

EXAMPLE OF PRONET AX NETWORK WITH AX800A AND SW1800A

Assign the ID number
To work properly in a PRONET AX network each connected device must have a unique identifier 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 instructions:

1. Switch off all the devices.
2. Connect them correctly to the network cables.
3. “TERMINATE” the end device in the network connection.
4. Switch on the first device keep pressed “PRESET” button on the control panel.
5. Leaving the previous device switched on, repeat the previous operation on the next device, until the latest device is turned on.

The “Assign ID” procedure for a device makes the internal network controller to perform two operations: reset the current ID; search the first free ID in the network, starting from ID=1. If no other devices are connected (and powered on), the controller assume ID=1, that is the first free ID, otherwise it searches the next one left free.
These operations 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 operation of step 4. Every device maintains its ID also when it is turned-off, because the identifier 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 first time the system is turned on.

For more detailed instruction about PRONET see the PRONET AX USER’S MANUAL included with the software.
PREDICTION SOFTWARE: EASE FOCUS 3
To aim correctly a complete system we suggests to use always the Aiming Software – EASE Focus 3:
The EASE Focus 3 Aiming Software is a 3D Acoustic Modelling Software that serves for the configuration and modelling of Line Arrays and conventional speakers close to reality. It only considers the direct field, created by the complex addition of the sound contributions of the individual loudspeakers or array components.
The design of EASE Focus is targeted at the end user. It allows the  easy and quick prediction of the array performance in a given venue. The scientific base of EASE Focus stems from EASE, the professional electro- and room acoustic simulation software  developed by AFMG Technologies GmbH. It is based on the EASE GLL loudspeaker data file required for its use. The GLL file contains the data that defines the Line Array with regard to its possible configurations as well as to its geometrical and acoustical properties.

Download the EASE Focus 3 app from the AXIOM website at https://www.axiomproaudio.com/ clicking on downloads section of the product.

Use the menu option Edit / Import System Definition File to import the GLL file, the detailed instructions to use the program are located in the menu option Help / User’s Guide.
Note: Some windows system can require the .NET Framework 4 that can be download from website at https://focus.afmg.eu/.

NOTE: in this figure is shown the result of an horizontal cardiod ground stack for the 80Hz octave.

CARDIOID SET UP

The cardioid preset must be used in a sub array of three SW1800AV2. Two box must be oriented towards the audience and one must be turned in the opposite direction (typically the box in the centre of the array). The bottom 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 cancellation on the back side of the array it has the phase inverted and a proper level and delay setting.
The following figures show two typical displacement of the array. The first with all the boxes in horizontal position for a total height of 1710 mm and a width of 960 mm. The second one with all the boxes in vertical position for a total height of 960 mm and a width of 1710 mm.
NOTES:
When placing the cardioid array keep a distance to walls or other obstacles of at least 80 cm (2.6 ft) in order not to affect the radiation of the reversed cabinet.

NOTES:
When placing multiple vertical cardioid arrays keep a distance between them of at least 110 cm (3.6 ft) in order not to maximize the combined radiation of whole arrays.

NOTES:
When placing multiple horizontal cardioid arrays keep a distance between them of at least 80 cm (2.6 ft) in order not to maximize the combined radiation of whole arrays.
