2 Safety Notes
The unit corresponds to all relevant directives of
the EU and is therefore marked with
.
Please observe the following items in any case:
G
The unit is suitable for indoor use only. Protect
it against dripping water and splash water,
high air humidity, and heat (admissible ambi-
ent temperature range 0 – 40 °C).
G
Do not place any vessels filled with liquid, e. g.
drinking glasses, on the unit.
G
The heat being generated in the unit must be
carried off by air circulation. Therefore, the air
vents at the housing must not be covered.
G
Do not set the unit into operation, or immedi-
ately disconnect the mains plug from the
mains socket if
1. there is visible damage to the unit or to the
mains cable,
2. a defect might have occurred after a drop or
similar accident,
3. malfunctions occur.
The unit must in any case be repaired by
skilled personnel.
G
Never pull the mains cable to disconnect the
mains plug from the mains socket, always
seize the plug.
G
For cleaning only use a dry, soft cloth, never
use chemicals or water.
G
No guarantee claims for the unit and no liabil-
ity for any resulting personal damage or mate-
rial damage will be accepted if the unit is used
for other purposes than originally intended, if it
is not correctly connected or operated, or not
repaired in an expert way.
3 Applications
The amplifier system TXA-15USB consists of a
3-channel mixer with integrated audio player,
Bluetooth receiver and a 15 W digital amplifier.
These components are built into a 2-way
speaker system which can easily be transported
due to 2 castors and an extractable telescopic
handle.
The unit can either be operated with 230 V
mains voltage or via the internal lead gel battery
which can be recharged with the integrated
charger. Thus, the amplifier system is also opti-
mally suited for mobile applications, e. g. for lec-
tures or sales events.
4 Transporting
and Placing the Unit
To transport the TXA-15USB, press the unlock-
ing button at the telescopic handle and extract
the handle so far as desired until it locks into
place. By slightly tilting the unit, it stands on both
castors only and can thus be pulled conven-
iently. After transport, press the unlocking button
again and slide the telescopic handle back into
the unit.
The unit can be placed on the floor as
desired or onto a stand for speaker systems
(e. g. series PAST-xxx from MONACOR) via the
stand sleeve on the lower side.
5 Connections
Prior to connecting units or changing existing
connections switch off the amplifier system and
the units to be connected.
5.1 Microphones and audio unit
1) Unbalanced microphones with a 6.3 mm
plug can be connected to the combined
jack MIC 1 IN (1) and to the 6.3 mm jack
MIC 2 IN (3).
A balanced microphone with an XLR plug
or a 6.3 mm plug can be connected to the
combined jack MIC 1 IN.
2) An audio unit with line signal level (e. g. CD
player, cassette tape recorder) can be con-
nected to the RCA jacks CD / TAPE IN (5).
5.2 Recorder or
additional amplifier system
A recorder or another audio unit with line input
(e. g. an additional amplifier system for PA appli-
cation of a larger area) can be connected to
the 6.3 mm jack LINK OUTPUT (17). Here, the
mixed signal of the audio sources is available,
not affected by the adjustment of the control
MASTER VOL (11).
5.3 Power supply
The unit can be supplied with power via the
230 V mains or via the internal lead gel battery.
5.3.1
Mains operation
Connect the supplied mains cable to the mains
jack (13) and the mains plug to a socket (230 V~ /
50 Hz).
Note: As soon as the unit is connected to the mains, the
automatic charging of the battery is switched on, even
when the unit is switched off. Therefore, disconnect the
mains plug from the socket when the battery is charged
[charging LED CHARGE (15) does not light up] and the
unit will not be used for a longer time. Otherwise there
will be unnecessary power consumption.
5.3.2
Operation of the rechargeable battery
For a long battery life, recharge the battery prior
to the first operation and when the battery LED
LOW (18) lights up. When recharging, the unit
can be operated.
To recharge the battery, connect the sup-
plied mains cable to the mains jack (13) and the
mains plug to a socket (230 V~ / 50 Hz). The unit
does not have to be switched on for recharging.
When recharging, the LED CHARGE (15) lights
up. When the battery is fully charged, the LED
CHARGE will be extinguished.
Note: Due to the protective charging circuit the battery
cannot be overcharged. However, the mains plug
should be disconnected from the socket after charging
when the unit will not be in operation for a longer time.
Otherwise there will always be low power consumption,
even when the unit is switched off.
Hints and tips for a long life of the integrated
12 V battery:
– Fully charge the battery before initial opera-
tion.
– Recharge a discharged battery as soon as
possible.
– If the amplifier system is not in use for a longer
period of time, fully recharge the battery every
3 – 6 months.
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.
WARNING The unit uses dangerous mains
voltage. Leave servicing to skilled
personnel only and do not insert
anything into the air vents. Inex-
pert handling may result in electric
shock.
