1 Applications
This active speaker system of the series TXA-
1020 is a combination of a two-way speaker
system and a class D amplifier and is especially
designed for mains-independent operation . For
power supply, the unit is equipped with two lead
gel batteries that are charged when the unit is
connected to the mains . Thus, the unit is ideally
suited for mobile PA applications, e . g . at events
and lectures .
The active speaker system is equipped
with controllable inputs for the connection of
two microphones and two audio sources with
line signal level (e . g . CD / MP3 player) as well
as with two outputs (e . g . for the connection
of another active speaker system) . Audio data
of a Bluetooth audio source (e . g . smartphone)
can be reproduced via the integrated Bluetooth
receiver . For operation with two wireless trans-
mitters, the unit includes a two-channel receiver
module (2 × 16 channels in the UHF frequency
range 863 .1 – 864 .9 MHz) . The transmitters of
the series TXA-800, for example,may be used
as wireless transmitters .
