INTRODUCTION
The SW2100A is a very compact Band-Pass/Bass-Reflex subwoofer providing high
output and extended low-frequency response.
It is equipped with a single 21” neodymium transducer with a 4” ISV voice
coil, large displacement suspension system, and composite reinforced, water-
repellent cone, able to provide clean and undistorted LF reproduction at very
high SPL.
The system processing is based on the CORE DSP platform designed by the PROEL
R&D
Laboratories using one of the most advanced SHARC DSPs for audio applications.
It features 40bit, 96kHz floating point resolution, and top-quality 24bit
AD/DA converters, for perfect signal integrity, dynamic range over 110dB, and
superior sonic performance. The PRONET
AX control software, working on a solid and reliable CANBUS-based network protocol, provides an intuitive interface for the remote control of the whole system, with the possibility of EQing, delaying, managing the protection functions, and monitoring the status of the amplifier.
The SW2100A is powered by a DA SERIES digital power module, a new generation
of CLASS D
power amplifier with digitally-controlled SMPS. The innovative technology used
for these amplifiers (including also the use of a variable switching
frequency) 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. The DA module employed for
powering the SW2100A features also PFC (Power Factor Correction), a technology
able to guarantee always the highest level of power regardless of any eventual
fluctuations of the power supply.
The SW2100A has been mainly designed to provide the optimal low-frequency extension to the AX12C line array module. The built-in DA power module can provide 2000W to drive the 21” woofer and 2000W to power up to four AX12C line array modules connected to the output SPEAKON. The built-in CORE DSP provides 4 presets for different combinations: 2, 4 or 1 columns plus 1 user preset (additional presets for processing other AXIOM speakers are also available).
The SW2100A features on the top panel a special metal plate and it comes with a dedicated aluminium bracket for fast coupling with the AX12C’s rigging hardware. Using this simple system, up to two AX12C modules can be easily installed on an SW2100A.
TECHNICAL SPECIFICATION
I/O AND CONTROL OPERATIONS
WARNING! Connect no more than one subwoofer unit to the MAINS~ OUT
connector.
WARNING! If you use the MAINS~ OUT turn on each subwoofer unit one at a
time.
WARNING! In the case of product failure or fuse replacement, disconnect
the unit completely from the main power.
WARNING! 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 instructions
downloadable from the NEUTRIK WEB site at: http://www.neutrik.com/
ON – This LED indicates the 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 the same audio signal.
GND LIFT – This switch lifts the ground of the balanced audio inputs from
the earth-ground of the amplifier module.
PRESET BUTTON – This button has two functions:
-
Pressing it while powering on the unit
ID ASSIGN the internal DSP assigns a new ID to the unit for the PRONET remote control operation. 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. -
Pressing it with the unit ON you can select the DSP PRESET. The selected PRESET is indicated by the corresponding LED:
2 x AX12C This PRESET allows to the connection of two AX12C column array elements to the POWER OUTPUT Speakon connector, see example. 4 x AX12C This PRESET allows to connection of four AX12C column array elements to the POWER OUTPUT Speakon connector, see an example. 1 x AX12C This PRESET allows the connection of one AX12C column array element to the POWER OUTPUT Speakon connector, see an example.
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 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 software, and save the PRESET into USER MEMORY no. 1.
- NETWORK IN/OUT – These are standard RJ45 CAT5 connectors (with optional NEUTRIK NE8MC RJ45 cable connector carrier), used for PRONET network transmission of remote control data over long distances 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.
- POWER OUT – SW2100A can power the passive AX12C column array module (or other loudspeakers) through the available power output on the back panel.
WARNING: for optimal protection and equalization connect the exact number of AX12C modules specified by the selected PRESET.
POWER AMPLIFIERS
The SW2100A is powered by DA SERIES digital power modules, a new generation of
CLASS D power amplifiers with digitally-controlled SMPS. The innovative
technology used for these amplifiers (including also the use of a variable
switching frequency) offers performances at the top of the range, such as a
superior sound definition at any audio frequency, very high dynamics for low-
level signals, and very low distortion 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 higher dynamics, very compact size and
lightweight, and efficiency above 90%. The DA module employed for powering the
SW2100A features also PFC (Power Factor Correction), a technology able to
guarantee always the highest level of power regardless of any eventual
fluctuations of the power supply. It delivers in an ultra-compact package
2000W (@ 4 ohms) from each of its two channels: one channel is used to drive
the 21” woofer, and the other, through an output SPEAKON connector, can power
AX12C line array modules or other loudspeakers.
SIGNAL PROCESSING
The system processing is based on the CORE DSP platform, which has been
designed by the PROEL R&D Laboratories using one of the most advanced SHARC
DSP for audio applications. It features 40bit, 96kHz floating point
resolution, and high-quality 24bit AD/DA converters, for perfect signal
integrity, a dynamic range over 110dB, and superior sonic performance. Thanks
to its massive processing power, the CORE platform is capable of providing the
most sophisticated algorithms for speaker processing, together with remote
control and networking capability.
The PRONET control software, working on a solid and reliable CANBUS-based
network protocol, provides an intuitive interface for the remote control of
the whole system, with the possibility of eqing, delaying, increasing the
protections, and monitoring the status of the amplifier.
PRONET AX
- PRONET AX software has been developed in collaboration with sound engineers and sound designers, to offer an “easy-to-use” tool to set up 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.
- You can download the PRONET AX app from the AXIOM website at http://www.axiomproaudio.com/.
The AXIOM active loudspeaker devices can be connected to a network and controlled by the PRONET AX software, for the network connection the PROEL USB2CAN (with 1-port) or the USB2CAN-D (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’s network output is connected to the network input connector of
the third device, and so on. To ensure 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 last device. For the network connections simple
RJ45 cat.5 or cat.6 ethernet cables can be used (please don’t confuse an
ethernet network with a PRONET AX network these are completely different 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 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 unique ID equal to or greater than 1: in the network, two devices with the same ID.
To correctly assign a new available ID to each device for working properly in a Pronet AX network, follow these instructions:
- Switch off all the devices.
- Connect them correctly to the network cables.
- “TERMINATE” the end device in the network connection.
- Switch on the first device and keep pressing the “PRESET” button on the control panel.
- 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 perform two operations: reset the current ID; and search the first free ID in the network, starting from ID=1. If no other devices are connected (and powered on), the controller assumes ID=1, which is the first free ID, otherwise, it searches for the next one left free.
These operations ensure that every device has its 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 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.

included with the software.
TOOLS
This is a list of tools that can be useful to set properly a vertical column
array system or a complex point source system.
CABLE TESTER
It is a good practice to check all cables before each installation because
even one faulty cable can compromise heavily the system performance.
INCLINOMETER WITH LEVER
This tool can be used to verify the vertical array angle. It can be used at
the top or at the bottom of the array In this case you have to sum all splay
angles, so the maximum precision is needed for aiming the vertical array,
particularly for long throw applications.
LASER DISTANCE METER
This instrument can be useful to measure the height of the vertical array and
to know the distance between FOH-Subs and FOH-Array for setting the delay
time.
ACOUSTIC MEASUREMENT SYSTEM (SMAART, SATlive, or similar)
These are useful for measuring delays, phases,s and responses of the system.
