The Plena mixer is a high performance, professional
public address mixer with modern state of the art
features. Combined with the PLE-1P120-EU or
PLE-1P240-EU amplifiers, you can build an easy-to-
operate yet powerful and flexible public address
system. All this without sacrificing features such as
ducking, priority, and flexibility. The mixer fulfills a
wide variety of public address requirements yet is
surprisingly affordable.
Functions
Inputs
All Mic/line inputs can be switched between
microphone level and line level sensitivity. The inputs
are balanced and can also 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) input, or the input can be switched
automatically if a signal is fed to the input, i.e. if
someone speaks into the microphone (VOX
activation). A 2-tone chime can be configured to
precede an announcement
• Input 2 also has a VOX possibility. When one or both
inputs are configured for priority, the attenuation
(reduction) of the cinch input can be set between
‑2 dB (little attenuation) and -∞ 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.
Labels and colored pins
More unique features are available such as a
detachable label 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 green pins to configure
the system for their particular use. A second user can
set all controls to the red pins for their configuration.
Unique features
Separate music inputs are available with their own
input selector, volume control and tone control. The
user can choose a music source such as a CD player or
radio (like the PLN-DVDT), and set the music level. A
desired sound for the music source can be set
separate from the mic/line inputs. So if the music

requires boosted low frequencies, the microphone
voices will still be clear – a truly unique feature in its
class.
The tone controls also have the following unique
features:
• The mixer features separate tone controls for mic/line
inputs and music inputs so the microphone voice can
be specifically optimized for excellent speech or
singing
• The tone controls for music enable the most suitable
music reproduction
In addition, the tone controls are not standard bass
and treble controls; our experience has enabled us to
develop a tone control that can be used as a
traditional tone control with high and low control, but
with a powerful contour that addresses the problems
that are found in real situations.
The tone control for the microphone and line inputs:
• boosts warmth in voices without boosting rumble,
and cuts rumble without losing warmth in the low
frequencies
• boosts sparkle without adding sharpness in the high
frequencies when boosting, and reduces harshness
and sharpness without reducing clarity when cutting
The tone control for the music inputs:
• boosts deep bass first without making the sound
hollow or boomy, and cuts rumble without losing
warmth in the low frequencies
• boosts sparkle without adding sharpness in the high
frequencies, with slightly different frequencies to suit
music reproduction
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.
Zones
The mixer has two zone outputs. The music can be
switched on and off in the zones via the front panel
and optional wall panel. Announcements from the
PLE-2CS two-zone call station can be routed to zone 1
or zone 2, or both. Announcements from the tel/100 V
input or inputs 1 & 2 are routed to both zones. Input 1
can be used for a PLE-1CS all-call call station or any
other microphone or call station with a PTT contact.
The unit also has a line output to connect the pre-
amplifier output before zone selection, making it
possible to create a third zone. This output can be
switched to music only, for example, so that music on
hold can be provided for the telephone system. Loop-
through input and output connections enable external
sound processing equipment (e.g. an equalizer or
Plena feedback suppressor) while maintaining a
balanced connection to the amplifiers.
Output status
An LED VU meter monitors the master output. A
headphone socket, below the VU meter, provides the
mixer output before zone selection so you can listen to
the output before the signal is sent to the zone.
