Overview
The amplifier system MobileSys is powered by a rechargeable battery and thanks to it's
other main feature - a rucksack, it can be carried during processions, for example. The
amplifier is equipped with mixable inputs for a microphone, a (stereo) audio source with line
level and an (optional) receiver for a wireless microphone.
It is possible to gradually or immediately mute the music while speaking to the
microphone. With a fully charged battery, the system can operate for up to 10 hours. An
internal chamber where a second battery can be placed and hooked up, makes it possible to
double that time. Compartments for items such as microphones and cables are located in
the rucksack.
Provided that all the systems concerned are equipped with the same wireless receiver, the
wireless signal from the microphones can be simultaneously received by multiple
MobileVoice devices. The feature allows the sound from the mics to be distributed to a much
larger or elsewhere located area.
1) Prior to initial switch-on, set all volume con-trols (1, 2, 3) to “0” to avoid an unexpectedly
high volume when the amplifier is switched on..
3) Use the POWER switch (12) to switch on the amplifier. The LED power indicator AMP
ON (13) will light up. In addition, the appropriate LED (14) will indicate the current charging
state of the rechargeable battery. When the LED LOW lights up, the battery must be
recharged.
WARNING Never operate the amplifier when the speakers are close to anybody’s ears! The
high volume may cause hearing damage. To avoid acoustic feedback (loud howling), never
4) Adjust the volume of the audio sources with the corresponding control (1, 2, 3).
2) Switch on the the wireless transmitter and audio sources if any was connected.
Getting started
When the battery has been recharged, dis-connect the power supply unit from the ampli-fier
and the mains.
Never put defective rechargeable batteries in the household waste. To protect
the environment, always take them to a special waste disposal, e.g. collection
container at your retailer.
To recharge the built-in battery and an additionally connected battery, connect the power
supply unit provided to the low-voltage jack (9) and to a mains socket (230V~/50Hz). The
LED CHARGE (15) and the LED corresponding to the current charging state – FULL, OK or
LOW – will light up and the battery will be recharged. The amplifier may be switched off
during recharging..
Battery
7) To avoid unnecessary discharging of the battery, switch off the amplifier with the switch
POWER (12) after operation or during longer pauses.
If the amplifier system is going to be idle for a longer period of time, fully charge the
battery before storage and recharge it approx. every 2 months to prevent the battery
from damage.
position the speaker towards the microphone and always make sure that there is a sufficient
distance between the speaker and the microphone..
A level limiter will automatically prevent dis-tortions at high volumes. The LED LIMITER
(13)will light up when the limiter is active.
5) Use the control TONE (16) to adjust the desired sound for the microphones or for an
audio source connected to the jack (2); use the con-trol TONE (10) to adjust the sound for
an audio source connected to the jacks LINE IN.
6) To automatically mute music, for example, of an audio source connected to the jacks
LINE IN (3) during announcements via the microphone [VOICE OVER (11)], adjust the
control DEPTH in such a way that the LED MUSIC will light up while speaking into the
microphone.

Safety notes
Never pull the mains cable for
disconnecting he mains plug from the
socket.
by qualified LDM service personnel.
- For cleaning only use a dry, soft cloth;
never use chemicals or water.

connected, operated, or not repaired in an
expert way.
Please observe the following items in any
case: The unit is suitable for indoor use
only. Protect it against dripping water and
splash water, high air humidity, and heat
(admissible ambient temperature range
0 – 40 °C).
- in case of visible damage to the unit or
to the mains cable,
- if a defect might have occurred after the
unit was dropped or suffered a similar
accident,
2. The heat generated within the unit must
be carried off by air circulation. Therefore,
do not cover the air vents.
1. Do not place any vessel filled with liquid
on the unit, e. g. a drinking glass.
3. Do not operate the unit and immediately
disconnect the mains plug from the
socket:
- if malfunctions occur.
1. Do not:
- expose the device to rain
- use it near water or in damp or wet
conditions
- place containers on it containing liquids
which might spill into any openings.
3. Use only the power cord delivered by the
manufacturer.
4. If this device appears to be damaged,
immediately turn off the power switch,
disconnect the electric plug from the outlet,
and have the device inspected by qualified
LDM service personnel.
2. Do not expose the device to excessive
dust or vibrations, or extreme cold or heat
(such as in direct sunlight, near a heater, or
in a car during the day)
Always follow the basic precautions listed
below to avoid the possibility of serious
injury or even death from electric shock,
short-circuiting, damages, fire or other
hazards
ATTENTION!
Remove the electric plug from the outlet
when the device is not to be used for
extended periods of time, during electrical
storms or when the device is under repair
. When removing the electric plug from the
device or an outlet, always hold the plug
itself and not the cord. Pulling by the cord
can damage it.
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not
harmful to the environment.
