These Plena mixer amplifiers are high performance,
professional public address units with modern state of
the art features. They are easy to use, taking the
complexity away from the user and putting it where it
belongs, inside the equipment. Providing a crisp call or
clear music is as easy as turning on the radio.
The amplifier is also surprisingly affordable, without
sacrificing features such as ducking, priority and
flexibility.

microphone (VOX activation).
