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.
