ITALIANO POLSKI ESPAÑOL FRANCAIS DEUTSCHENGLISH7 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)

• 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).

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

• airplanes or vehicles

• Areas where cell phone use is prohibited

Temporary operation! Event equipment is basically only designed for temporary operation.

Continuous operation or permanent installation can lead to impairment of the function and premature aging of the devices. DEUTSCHFRANCAIS ESPAÑOL ENGLISH ITALIANO POLSKI8

• 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. MAILA ITALIANO POLSKI ESPAÑOL FRANCAIS DEUTSCHENGLISH9

Always place the subwoofer in a suitable place on a sufficiently stable, level and horizontal surface. Make sure that the subwoofer or the speaker system cannot fall off the edge of the stage (e.g. due to vibration).

POWER INPUT PowerCON TRUE1 power input jack. A suitable power cord is included in the scope of delivery

POWER On-off switch. Always turn the speaker on as the last device in the signal chain and turn it off as the first device.

POWER OUTPUT The PowerCON TRUE1 mains output socket is used to supply power to other system components. Make sure that the total power consumption of all connected devices does not exceed the value specified in amperes (A) on the device!

INPUT Balanced line input with locking, female 3-pin XLR socket.

THRU Balanced line output for forwarding the line input signal (male 3-pin XLR socket).

LC-DISPLAY Multifunctional graphic LC display with lighting.

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.

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.

VENTILATION OPENINGS To avoid damage to the device, do not cover the ventilation openings on the back and ensure that air can circulate freely. ITALIANO POLSKI ESPAÑOL FRANCAIS DEUTSCHENGLISH11 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.
