SIGNAL TRANSMISSION VIA RADIO (e.g. W-DMX or audio radio systems, Bluetooth):
The quality and performance of wireless signal transmissions generally depends on the
environmental conditions.
Influence on the range and signal stability, for example:
• Shielding (e.g. masonry, metal structures, water)
• High radio traffic (e.g. strong W-LAN networks)
• interference
• Electromagnetic radiation (e.g. LED video walls, dimmers)
All range specifications refer to free field use with visual contact without interference!
The operation of transmitters is subject to official regulations. These can vary from region to
region and must be checked by the operator before commissioning (e.g. radio frequency and
transmission power).
WARNING:
Devices with wireless signal transmission are not suitable for operation in sensitive areas in
which radio operation can lead to possible interactions. These include, for example:
• Hospitals, health centers or other healthcare facilities that perform patient treatments
with specialized staff and equipment.
• Class I, II and III hazardous areas
• restricted areas
• military facilities
• airplanes or vehicles
• Areas where cell phone use is prohibited
NOTES FOR PORTABLE INDOOR DEVICES
1.
Temporary operation! Event equipment is basically only designed for temporary operation.
2.
Continuous operation or permanent installation can lead to impairment of the function
and premature aging of the devices.

SCOPE OF DELIVERY
Take the product out of the packaging and remove all packaging material.
Check the completeness and integrity of the delivery and please notify your sales partner immediately
after purchase if the delivery is incomplete or damaged.
The scope of delivery of the product includes:
• 1x LD MAILA subwoofer
• 1x power cord
• operation manual
PROPERTIES
MAILA SUB forms the basis of every MAILA system. The 2.5 kW 2x15'' high-performance subwoofer works
in bandpass design and, with its newly developed SysCore® DSP, delivers a massive and powerful bass
foundation in every application.
The acoustic concept of the MAILA SUB is based on a planar wave bandpass design with a quarter wave
horn and a symmetrical driver structure. By arranging the two 15'' speakers opposite each other, the
MAILA SUB enables exceptional impulse compensation, which results in powerful and precise low-fre-
quency pressure.
The four large-area bass reflex openings, in conjunction with the housing design, ensure optimized
air flow and reduced flow losses, which not only leads to a lower noise level, but above all to higher
efficiency at low frequencies.
The housing of the subwoofer consists of 18 mm thick birch plywood with integrated steel braces. The
MAIL SUB defies the tough everyday road life with a hard-wearing polyurea finish. A total of six carrying
handles ensure optimal grip during assembly and disassembly. The optional MAILA SUB CB roller board
is the ideal choice for comfortable transport over long distances.
With LogoLink®, LD Systems has donated another innovation to MAILA. With the free MAILA App (iPadOS),
every MAILA system can be adjusted quickly, easily and in detail and wirelessly supplied with software
updates. Once connected, the app automatically recognizes the existing MAILA components and ena-
bles the system to be optimally set up before and during an event. The highlight: The required wireless
antennas are invisibly integrated into the LD logo of the MAILA SUB.
MAILA APP (iPadOS)
The MAILA app for iPadOS is available free of charge in the App Store.
CONSTRUCTION
The subwoofer has 6 ergonomic carrying handles that allow for comfortable transportation. Non-slip
rubber rails are located on the bottom and on one side of the housing, so that the subwoofer can be
placed both vertically and lying on its side. A connecting plate for the LD MAILA COL speaker column is
located on the top of the subwoofer and one on the side opposite the side rubber rails. M20 threads for
mounting the LD MAILA DB distance rod and for securing the MAILA COL speaker column are also located
in the connecting plates.

Rotary push encoder for navigating the main menu and submenus and adjusting system settings.
Select the individual menu items in the main menu and in the submenus by turning the encoder and
confirm the selection by pressing the encoder. Change a numerical value or status in a menu item by
turning the encoder and confirm the change by pressing the encoder. To go one level higher in the
menu structure, select the arrow symbol < and confirm the selection.
Press the encoder for about 2 seconds to mute the subwoofer and again for about 2 seconds to unmute it.
8LEDS TO INDICATE DEVICE STATUS
PWR - (Power) The white indicator LED lights up when the device is correctly connected to the mains
and switched on.
SIG - (signal) The white indicator LED lights up when an audio signal is present at the device.
LIMIT - (limiter) The yellow indicator LED lights up when the loudspeaker system is operated in the
upper limit range. A brief flashing of the LED is not critical. To protect the system, an excessive
signal level is gently reduced by the integrated limiter. If the limiter LED lights up longer or stays on,
reduce the volume level.
PROT - (Protect) The red indicator LED lights up if the subwoofer is overloaded or overheated. The
subwoofer is automatically muted. After reaching normal operating conditions, the device switches
back to normal operating mode after a few minutes.
9VENTILATION OPENINGS
To avoid damage to the device, do not cover the ventilation openings on the back and ensure that air
can circulate freely.

SERVICE
HINTS
• When the subwoofer is switched on, all settings such as PRESET and EQUALIZER are loaded as they were
before the subwoofer was switched off. The subwoofer is ready for operation after a short time.
• After about 30 seconds without any input via the turn-push encoder, the display system exits Levels in
the menu structure and the main display with the selection VOLUME is automatically displayed.
DISPLAY MAIN
In normal operation, the main display is activated, with the main menu, the set delay and the activated
preset being displayed. The Bluetooth status, the volume level (LVL) and the gain (VOL) are displayed
graphically.
If the top segment of the level display lights up red, this indicates that the input stage is being operat-
ed above the distortion limit (clip). Reduce the output level of the playback device (e.g. mixer) until the
clip segment no longer lights up and the subwoofer reproduces audio signals without distortion.
VOLUME
To adjust the level of the subwoofer, select VOLUME in the main menu off, confirm, then set the desired
value from -40 dB to +10 dB and confirm again.

2. Air inlet and outlet openings must be regularly cleaned of dust and dirt. If compressed air is used,
care must be taken to prevent damage to the device (eg fans must be blocked in this case).
3. Cables and plug contacts must be cleaned regularly and freed from dust and dirt.
4. In general, no cleaning agents or agents with an abrasive effect may be used for care, otherwise the
surface quality can be expected to be impaired.
5. Devices should generally be stored in a dry place and protected from dust and dirt.
