ASSEMBLY, CONNECTION, AND OPERATION
GENERAL INFORMATION Both the subwoofer of the LO Systems MAUI 44 G2 PA system
and the optional subwoofer extension MAUI 44 G2 SUB must be positioned on a
flat surface on their rubber feet before use. Never operate the system on a
trolley as there is a risk that the entire system may begin to move in an
uncontrolled manner. This may result in accidents and damage. The amplifier is
cooled via the heat sink below the connection panel on the back of the
subwoofer. To ensure sufficient cooling during operation, a minimum distance
of 50 cm must be maintained between the back of the subwoofer and other
similar objects such as walls. Please ensure that the system as well as any
connected devices such as mixing consoles, CO play-ers etc. are connected to
the correct audio and power connections. use only undamaged cables with a
suitable diameter and always unroll cable reels fully. Use cable protectors to
avoid tripping accidents caused by loose cables. Never position the device
directly on an edge. Do not place the subwoofer on a table. In order to
eliminate unwanted noise when turning on connected devices, always switch the
system on last and switch it off first
ASSEMBLY
The LO Systems MAUI 44 G2 PA system comprises three components:
A . Subwoofer with integrated electronics for all system components.
B. MAUI 44 G2 LC:
lower vertical array column with six 3.5″ speakers, each with a multipin
connector on the top and bottom and a guide pin on the underside.
C. MAUI 44 G2 U:
The upper vertical array column with six 3.5* loudspeakers with phase plug,
tweeters, and a multi-pin connector and guide pins on the bottom side.
After the subwoofer has been placed in the desired position, the lower array
column is attached to the subwoofer. Rugged guide pins help the multipin
connectors on each speaker to interlock perfectly. One strong magnet provides
extra stability. The upper vertical array column is then attached to the lower
column in the same way.
To simplify transport, set-up, and dismantling, two ergonomic handles are
located on the sides of the subwoofer and an optionally available castor board
(LOM446203) can be installed on the back that also provides protection for the
connection panel and controls during transport Recessed handles are located on
the top and underside of the array columns.
The optional MAUI 44 G2 SUB subwoofer extension is positioned next to the MAUI
44 G2 PA system. The orientation of the subwoofer extension depends on whether
the cardioid preset in the subwoofer extension is used or not
CONNECTION AND OPERATION
A playback device can be connected via the balanced XLR inputs. The integrated
Bluetooth module enables wireless control via smartphone or tablet. There is
also a stereo link function for wireless transmission of the Bluetooth signal
to another MAUI 44 G2 PA system as a stereo extension. Both the volume of the
entire system as well as the volume of the subwoofer relative to the overall
volume can be adjusted on the device. An optionally available subwoofer
extension can be used in two different setups together with the MAUI 44 G2 PA
system.

Both MAIN and SUB level controls and the Bluetooth unit with MS are disabled if the MAUI 44 G2 subwoofer is used as a subwoofer extension. A description of the cardioid setup can be found under point 9 CAR 01010 ON/OFF. -
HOLD TO LINK
The MAUI 44 G2 PA system is equipped with Bluetooth, which means that audio files from a Bluetooth playback device (e.g. smartphone or tablet) can be played back on the MAUI 44 G2 PA (maximum distance between the two devices depends on the surroundings).
To pair and connect the internal Bluetooth unit with a Bluetooth playback device, press and hold the HOLD TO LINK button for approximately 3 seconds until the Bluetooth display field above the button flashes rhythmically (approx. 3 Hz). Enable Bluetooth on your playback device and search on the user interface for available devices. Select “MAUI 44 G2” and pair your Bluetooth device with the Bluetooth unit of the MAUI 44 G2 PA system. If successfully paired, the Bluetooth symbol will light up permanently and playback can be started. The volume is controlled via the MAIN level control or on the playback device.
To disconnect a Bluetooth device and set the Bluetooth unit back to standby, press and hold the HOLD TO LINK button again for approximately seconds. To delete the entire list of paired devices (= factory default), press and hold the HOLD TO LINK and STEREO LINK buttons simultaneously for approximately 2 seconds. If the Bluetooth connection is interrupted (e.g. range is exceeded), the Bluetooth LEO will go out Connection can be restored automatically within approx. 90 seconds (Bluetooth device back in range). After 90 seconds, the connection can be restored with the Bluetooth playback device (connect paired device). When using a single MAUI 44 G2 PA system, any stereo signal is automatically summed to mono in the Bluetooth module.
Note: The Bluetooth and TWS functions are not available if the subwoofer is used as a subwoofer extension for an existing MAUI 44 G2 PA system. -
STEREO LINK/TWS
The MAUI 44 G2 PA system is equipped with a Bluetooth stereo link function (true wireless stereo), which means that if two MAUI 44 G2 systems are used, stereo audio signals transmitted via Bluetooth can also be played back in stereo without a cable connection between the two systems (the maximum distance between the two devices is 40 meters under optimal conditions). The system that is connected to the Bluetooth playback device is hereinafter referred to as the master unit, the stereo expansion as a slave unit. If the master unit with the Bluetooth playback device is connected to the slave unit the Bluetooth display field and the TWS display field on the master unit light up permanently. If the connection is successfully established between the slave unit and the master unit, the TWS display field on the slave unit lights up permanently and the Blue-tooth display field flashes slowly (approximately 03 Hz). During the pairing process, the TWS display fields on both systems flash rhythmically at a frequency of about 3 Hz.
Depending on the situation, there are two different methods to pair two MAUI 44 G2 PA systems via TWS:
Situation A. Stereo system with 2 x MAUI 44 G2 and1x Bluetooth playback device: Pair a Bluetooth playback device with the left MAUI 44 G2 system. The left-hand system automatically becomes the master unit. Disconnect all existing Bluetooth connections on the right-hand MAUI 44 G2 (press and hold HOLD TO LINK and STEREO LINK simultaneously for approximately 2 seconds). Now pair the right MAUI 44 G2 system with the master unit by pressing and holding the STEREO LINK button on both devices for approximately 3 seconds within 30 seconds. The right-hand system automatically becomes the slave unit (max. distance when pairing 15 m). The master unit transmits the left channel of the stereo signal from the Bluetooth device and the slave unit the right channel.
Situation B. Stereo system with 1 x MAIII 441,2. air RluPtooth playback device later: Disconnect all existing Bluetooth connections on the slave unit by simultaneously pressing and holding the HOLD TO LINK and STEREO LINK buttons on the slave unit for approximately 2 seconds. When pairing two MAUI 44 G2 systems, ensure that the distance between the systems is no more than 15 meters. Press and hold the STEREO LINK button on the master unit for approximately 3 seconds and press the STEREO LINK button twice in quick succession on the slave unit Pairing occurs place automatically within approximately 30 seconds. Pairing a Bluetooth playback device with the master unit can now be done later. The master unit transmits the left channel of the stereo signal from a Bluetooth playback device and the slave unit the right channel.
PLEASE NOTE:
• Only audio signals from a paired Bluetooth playback device can be transmitted via the TWS stereo link function. Audio signals at the line input will not be transmitted via TWS.
• When the MAUI 44 G2 systems have been switched off and back on, the Bluetooth playback device will pair automatically and the systems will connect with each other automatically via TWS.
• The maximum number of paired Bluetooth devices is 8 (including paired MAUI 44 G2 systems). If another device is paired, the last entry from the list of stored devices will be deleted. A maximum of one Bluetooth playback device and one MAUI 44 G2 system can be connected simultaneously with the MAUI 44 G2 master unit to create a stereo extension.

CARDIOID SUBWOOFER ON / OFF
Note: The cardioid subwoofer feature is only available when the loudspeaker columns are not connected to the MAUI 44 G2 subwoofer. MAIN / SLAVE operation: The optionally available MAUI 44 G2 SUB subwoofer extension can be used with the MAUI 44 G2 PA system in two different ways.
A. The subwoofer extension is positioned in the same orientation as the subwoofer of the MAUI 44 G2 PA system. In this case, the cardioid preset on the subwoofer extension must be disabled (CARDIOID OFF). Press and hold the CARDIOID button for about 2 seconds to change the status.
A. The subwoofer extension is positioned 180° to the subwoofer of the MAUI 44 G2 PA system. In this case, the cardioid preset must be enabled (CARDIOID ON). Press and hold the CARDIOID button for about 2 seconds to change the status. The cardioid setup results in more prominent bass dispersion at the front and a clearer stage sound at the rear due to extensive low-frequency cancellation.
