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.
Functions
Microphone and line inputs
All Mic/line inputs can be switched between
microphone level and line level sensitivity. The inputs
are balanced but can be used unbalanced. Phantom
power can be switched on to provide power to
condenser microphones.
Input channels 1 and 2 can take priority over all other
microphone and music inputs:
• Input 1 can be activated by contact closure on the
PTT (push to talk). A 2-tone chime can be configured
to precede an announcement.
• Input 2 can be switched automatically if a signal is
fed to the input i.e. if someone speaks into the
microphone (VOX activation).
When one or both inputs are configured to have
priority, the amount of attenuation (reduction) of the
cinch inputs, can be set between ‑2 dB (little
attenuation) or -∞ dB (mute). This provides a talk-over
or voice-over function. Input channels 1 and 2 also
feature selectable speech filters to enhance the clarity
of announcements.
Music inputs
Separate music inputs are available with their own
input selector and volume control. The user can
choose a music source like a CD player or radio (like
the PLN-DVDT), and set the level of music.
Personalized settings
More unique features are available such as detachable
labels where the user can write the names for inputs,
music sources and zones. These labels can then be
mounted on the front, protected by the clear window.
Another useful feature is to indicate preferred settings
on the front panel by inserting colored pins at the
preset levels of all knobs. You can then instruct a user
to set all the controls to the silver pins to configure
the system for their particular use. A second user can
set all controls to the red pins for their configuration.

Integration
A telephone / 100 V emergency input with VOX
activation is provided for easy integration with another
PA system or a telephone paging system. It has its own
preset volume control and overrides all other inputs,
including call station and inputs 1 and 2.
The unit also has a line output to add amplifiers for
larger systems with more output power. This output
can be switched to music only, for example, so that
music on hold can be provided for the telephone
system.
Power
The mixer amplifiers come in 30, 60 and 120 Watt
output power. This power is directly available on 100 V
constant voltage connections and on a low impedance
connection for an 8 ohm load. Moreover, the amplifiers
have a separate 100 V call-only output channel for
addressing areas where only priority announcements
are required. The call-only output can also be used for
3-wire remote, volume control override.
Output status
An LED VU meter monitors the master output. A
headphone socket, below the VU meter, provides the
mixer output. For total reliability and ease of use, a
limiter is integrated into the output stage to restrict
output if the user applies too much signal.
