PREVENTIVE MEASURES:
1. Please read the attached safety instructions as well as the following instructions carefully.
2. Please keep all the instructions.
3. Please use the device only as intended.
4. Please respect the valid waste management rules. Please deliver the packaging divided into plastic and
paper/ cardboard to the recycling management.
5. Please refer all servicing to qualified personel only if the device is damaged, exposed to liquid/rain or if it does
not operate normally.
6. Please, do not expose to any kind of heat such as ovens, radiators, or any other devices (incl. amplifiers).
Please check for enough distance between amplifiers and walls, racks, etc. to prevent overheating.
7. After connection please check the wiring to prevent any kind of accident or damage.
Please never use any kind of damaged cable and wiring.
8. Only use authorized and stable stands, brackets, shelfs, tables etc.. for installations. Please check for
adequate stability against collapse.
9. Appearance of interferences when using wireless systems.
The simultaneous use of wireless microphones and of mobile phones (if both devices are not very distant from
each other) can lead to the appearance of interferences in the microphone signal which can be heard in the
PA system.
CAUTION:
To reduce the risk of electric shock, do not remove cover (or back). No user serviceable parts inside. Refer
servicing to qualified personnel.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the
user to the presence of uninsulated “dangerous voltage” within the product´s enclosure that may be
of sufficient magnitude to constitute a risk to persons.
The exclamation mark within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (servicing) instructions in the literature accompanying the
appliance.
CAUTION! HIGH VOLUME!
You will operate this transmission system for professional use. Therefore the commercial use of this equipment
is liable to the rules and regulations of the Accident Prevention & Insurance Association of your industry sector.
Adam Hall as a manufacturer is bound to inform you formally about the existence of eventual sanitary risks.
This system is able to induce an acoustic pressure of 80 db. 85 db is by law the maximum audio pressure
level which your ear can be exposed to during a work day. It was set according to the technical expertise of the
occupational medicine as a basis for the noise rating level. Higher sound levels or longer exposition times could
damage your ear. The time of exposition by higher sound pressure levels should be shortened in order to prevent
from ear damages. Here are a few reliable warning signals which show that you have exposed yourself for a too
long period to excessive sound pressure levels:
- You hear bell- or whistling sounds!
- You have the impression that you can’t hear high tones anymore!

FEATURES & GETTING STARTED:
INTRODUCTION
The LD MAUI 28 (Multiple Array User Intuitive) is the perfect solution for musicians and DJs as well as presentati-
ons and events with sophisticated music playback.
Because no cables and stands are required, this “plug-and-play” system can be set up and taken down again
very easily and quickly. Frequency-response-based 4.1 five-way amping results in a clear, dynamic and balanced
sound throughout the frequency range of this system. The array configuration ensures greater coverage with very
well-balanced sound distribution even in the farthest corners of the venue.
The MAUI 28, which combines PA and monitoring system in one, guarantees the same sound experience for both
audience and musician. No disturbing speaker cables, no speaker stands, no transport issues, simply plug in the
mixer and you're ready to go.

SETUP, CONNECTION AND STARTUP:
TRANSPORT AND SETUP
The LD MAUI 28 active system is very compact and easy to transport. The subwoofer must be placed on the
rubber feet before use. Please NEVER use the system while it is on a transport trolley! There is a danger of
uncontrolled movement of the entire system. This can lead to accidents and damage. The amplifier cooling
elements are in the back of the subwoofer. When the amplifier is in use, please maintain a minimum distance of
50 cm between these cooling elements and other objects, walls, etc., to permit sufficient heat exchange.
Please make certain that the system and all connected source devices, mixers, CD players, etc. are properly
connected to one another and to the power mains. Use only undamaged cables with a sufficient cross-section
and only completely unrolled cable reels. Route the cables so as to avoid tripping hazards (gaffa tape). The unit
should never be positioned directly at an edge. Please also do not position the subwoofer on a table. It is ad-
visable to always turn the system on last and off first in order to avoid loud popping sounds when the connected
devices are turned on and off.
CONNECTION AND OPERATIONIt is possible to set both the overall system volume as well as the volume of the
subwoofer in relation to the overall volume. The ultimate volume level is then adjusted via the source device. The
connections permit both an unbalanced and an unbalanced connection (XLR / jack 6.3 mm) to a source device.
The position of the connectors and control elements of the LD MAUI 28 are shown on the following page.
SETUP
The LD Systems MAUI 28 all-in-one array system consists of the following three components:
1. Subwoofer with integrated electronics for all 3 parts of the
system.
2. The lower vertical array column with 8 x 3“ speakers and 2
multipin connectors, one each on the top and bottom.
3. The upper vertical array column with 8 x 3“ speakers, the
tweeter and a multipin connector on the bottom.
Once the subwoofer is positioned in the room that is to be filled
with sound, the lower vertical array column is plugged onto the
subwoofer. Four sturdy steel pins help ensure that the multipin
connectors of both speakers mate perfectly. Now the upper
vertical array column is simply plugged onto the lower column
according to the same principle. Special control electronics
use an LED to indicate that all parts of the system are properly
connected after the MAUI 28 array system is turned on.
