Frequently Asked Questions - MAUI 28 G2 LD Systems

How do I properly install the MAUI 28 G2 system?

First, place the subwoofer on a flat, stable surface. Then assemble the two half-columns by fitting them onto the subwoofer: the lower half-column (containing 8 mids) then the upper one (8 mids + tweeters). Use the steel guide rods for secure assembly. Always use both column elements. Leave at least 50 cm of space behind the subwoofer for cooling. Connect the power cable and audio sources. Always turn on the system last.

How do I connect a smartphone via Bluetooth to the MAUI 28 G2?

Press and hold the HOLD TO LINK button on the control panel for about 3 seconds until the Bluetooth LED flashes. Enable Bluetooth on your smartphone and search for available devices. Select 'LD MAUI28G2' from the list. Once paired, the blue LED stays on. Use the MP3/BLUETOOTH LEVEL knob to adjust the volume.

What does the LIMIT LED on the panel mean?

The LIMIT LED lights up when the system reaches its operating limits in terms of sound level. A brief flash is normal. If it stays on for a long time or permanently, reduce the master volume (MAIN LEVEL) to avoid excessive distortion that could damage the system. The built-in limiter protects the speakers.

How do I switch from mono to stereo mode?

Press the SYSTEM button (ref. 6) to toggle between modes. The corresponding LED (MONO or STEREO) lights up. In mono mode, the stereo signal is summed and output in mono on the SYSTEM OUT. In stereo mode, the left channel is reproduced by the main system and the right channel is sent to a second MAUI via SYSTEM OUT.

Can the MAUI 28 G2 column be mounted on a wall or on a stand?

Yes, using optional accessories. For wall mounting, use the LDMG2IK1 (recessed) or LDMG2IK2 (adjustable angle) kits. For stand mounting, use the LDMG2SPS (black) or LDMG2SPSW (white) stand. When the column is detached from the subwoofer, always use both column elements for the automatic DSP recognition to work.

What precautions should be taken to avoid hearing damage?

This system can reach high sound pressure levels (up to 126 dB SPL). Avoid prolonged exposure to levels above 90 dB SPL. Use hearing protection if necessary. Observe local regulations regarding sound levels.

How do I clean the MAUI 28 G2?

To clean the device, use a dry, lint-free cloth. Never use solvents, abrasive products, or liquids. Make sure no liquid enters the device. Disconnect the power cable before cleaning.

What should I do if the fuse of the MAUI 28 G2 blows?

First, disconnect the device from the mains. Replace the fuse with a new one of the same type and rating (indicated on the fuse holder, usually 250V). If the fuse blows again, do not use it and contact an authorized repair center. Never replace the fuse with a different model.

Can I connect an external subwoofer to the MAUI 28 G2?

Yes, the MAUI 28 G2 has a SUB OUT XLR output. Connect an active external subwoofer to this output. The signal taken depends on the position of the SUB LEVEL knob. You can thus reinforce the low frequencies.

What is the DynX® DSP and what is it used for?

The DynX® DSP is a digital signal processing that combines a multiband limiter, equalizer, compressor, and crossover (active filter). It optimizes sound quality by automatically adjusting frequencies, protects speakers from overload, and ensures clear and powerful reproduction. It adapts the sound depending on the setup (subwoofer, stand, or wall).

INTRODUCTION

Greatly facilitating your gigging life, the next generation of our MAUI ^® all-in-one column systems now comes with Class D amplification for increased power, punch and lighter weight. The line array design, BEM-optimized waveguides and LD Systems' innovative DynX ^® DSP technology result in distortion-free high definition sound with uniform dispersion and maximum coverage.

GENERAL INSTRUCTIONS

Before startup, the subwoofer of the LD Systems MAUI28G2 array system must be placed upright on its feet, on a flat surface. Never operate your system on a trolley, as there is a risk that the entire system might be unstable. Accidents and damage may result. To ensure adequate cooling, during operation a minimum distance of 50 cm must be maintained between the back of the subwoofer and other objects such as walls for example.

Please ensure the correct connection of audio and power for the system and all connected devices such as mixers, CD players, etc. Use only undamaged cables of suitable diameter and always unwind cable reels completely. If necessary, use cable bridges to avoid tripping over loose cables. Never place the device directly on an edge. Do not place the subwoofer on a table. To avoid unwanted background noise when turning on connected devices, always turn on the system last and turn it off first.

SETUP

The LD Systems MAUI28G2 array system consists of three components:

A. Subwoofer with integrated electronics for all system components.
B. Column speaker element with connectors on bottom and top.
C. Column speaker element with a connection on the bottom.

After setting up the subwoofer at the desired location, the lower column with the 8 midrange drivers is plugged into the subwoofer, and then the upper speaker column with 8 midrange drivers and the tweeters onto the lower column (please pay attention to the symbols on subwoofer and speaker columns, see drawing). Steel guiding pins facilitate the correct installation and ensure at the same time a secure hold. Using optional accessories, it is possible to mount the entire speaker pillar separately and attach it to a wall or a stand (two variants in each case).

IMPORTANT: In event of mounting on the subwoofer, always take care to ensure that both pillar elements are used and never only the upper pillar element. Otherwise, the automatic detection function will mute the system so as to avoid damage. In the event of separate mounting, always take care to ensure that both pillar elements are used and never only the upper pillar element. Otherwise, the automatic detection function will not work correctly and the system can potentially suffer damage.

The device allows both the volume of the entire system and the volume of the subwoofer in relation to the total volume to be adjusted separately. Source devices can be connected using both balanced and unbalanced cables (XLR / 6.3 mm jack / RCA / mini jack). The integrated 4-channel mixer offers a microphone input, a high-impedance instrument input for an electric guitar for example, an input for source devices with line level and furthermore a Bluetooth unit, which can be used in parallel to the 3.5 mm mini-jack input.

14 MP3 INPUT

Stereo line input with 3.5 mm jack socket for an MP3 player or other playback device. Both interfaces MP3 and Bluetooth ^® can be used simultaneously; the volume ratio must be set on the instrument, or on the external player.

15 BLUETOOTH®

The mixer of the LDMAUI28G2 array system is equipped with Bluetooth, meaning that audio files from another Bluetooth device (e.g. Smartphone) can be played back on the LDMAUI28G2 array system (maximum distance between both devices about 10 metres). If no Bluetooth device is connected to the internal Bluetooth unit, the blue Bluetooth LED does not light up; the LED flashes at a frequency of about 3 Hz during pairing; if the Bluetooth LED is on permanently, then a Bluetooth connection is established and the track playback can be started. The volume is adjusted using the Bluetooth® volume controller (N 16) or on the source device.

To pair and connect the internal Bluetooth device with a Bluetooth-enabled device, press and hold the HOLD TO LINK button for approx. 3 seconds until the Bluetooth LED flashes (approx. 3 Hz), enable Bluetooth on your Bluetooth device and search for available devices on the user interface. Select "LD MAUI28G2" and pair your Bluetooth device with the internal Bluetooth device. The playback can now start. To end the connection, press and hold the HOLD TO LINK button again for approx. 3 seconds. If the Bluetooth connection is interrupted (e.g. the range is exceed), the Bluetooth LED goes out. Within approximately 90 seconds, the connection will automatically be restored (Bluetooth device back within range). When 90 seconds is exceeded, the Bluetooth module of the LD MAUI28G2 array system will automatically be disabled.

16 MP3/BLUETOOTH LEVEL

Volume controller for the MP3 channel and the Bluetooth unit. When turned to the left, the volume is lowered, when turned to the right, it is increased.

17 SYSTEM OUT

Balanced line output with 3-pin male XLR socket.

If the Mono mode is activated (point 5 MONO / STEREO), the sum of all input channels will be rendered in Mono.

Select the Mono mode and use the SYSTEM OUT line output to control another MAUI28G2 Mono unit.

If the Stereo mode is enabled (point 5 MONO / STEREO), the left channel of all stereo inputs (N 9, 10, 14 and 15) is processed internally and rendered by the MAUI28G2 array system, while the right channel of all stereo inputs is rendered by the SYSTEM OUT line output to control another MAUI28G2 unit externally as a stereo expansion. The sum of the Mono channels MIC IN and HI-Z IN is output in equal parts internally on the left and externally on the right.

Note: To achieve the same volume as well as the same sound as the main unit with the stereo expansion, turn the volume controller of the stereo expansion LINE LEVEL clockwise (maximum) and place the SUB LEVEL and MAIN LEVEL in the same position as the SUB LEVEL and MAIN LEVEL of the main unit.

18 SUB OUT

Balanced line input with male 3-pin XLR socket for connecting an external active subwoofer. The signal is now picked up after the SUB LEVEL volume controller; it is therefore dependent on the latter.

WHAT DOES LD SYSTEMS DynX® DSP STAND FOR?

DSP stands for Digital Signal Processing, DynX® comprises the Limiter, EQ, Compressor and Crossover features. The digital signal processing ensures maximum audio performance with maximum clarity and protects the PA system from overload.

WHAT EXACTLY DOES DynX® DSP DO?

The Limiter function protects the speakers and prevents distortions caused by overload. Separate limiters for bass midrange and high range attenuate the signal when the level exceeds a value which could have a negative effect. Each limiter is optimised for one of the three seamlessly contiguous frequency ranges (multi-band limiter). The system can be operated in this manner with a higher overall sound pressure as extreme peaks are automatically lowered, so that the total volume does not need to be reduced. The Multiband EQ works over the entire frequency range and optimises the overall sound of the system.

The crossovers divide the audio signal according to the frequency range of the respective speakers, namely the subwoofer or the mids and tweeters of the array column. The amplitude and running-time optimisation of the crossover ensures that all frequencies are output evenly and reach the listener at the same time.
