3 Applications and Accessories
The 2-way bass-reflex speaker system TXA-
604 / SW with integrated 50 W amplifier is used
for monophonic sound applications at lectures
and other events . The amplifier is equipped with
a receiver module for two wireless microphones
and two inputs for audio units and a micro-
phone .
.
For mains-independent operation, an in-
tegrated rechargeable battery is provided . This
battery will be charged as soon as the active
speaker system is connected to the mains . Thus,
the unit is ideally suited for mobile applications .
The jacks LINE LINK (10) can be used to
interconnect multiple active speaker systems
for sound applications in large zones . A pas-
sive 4 Ω speaker system can also be operated
in parallel (e . g . the model TXB-602 / SW with a
matching design) .
