2 Description
2.1 The Plena product range
The Plena Easy Line Mixer is part of the Plena product
range. Plena provides public address solutions for places
where people gather to work, worship, trade, or relax. It
is a family of system elements that are combined to
create public address systems tailored for virtually any
application.
The Plena product range includes:
•mixers
• preamplifiers
• power amplifiers
• a music source unit
• a digital message manager
• a feedback suppressor
• call stations
• an All-in-One system
• a voice alarm system
•a timer
• a charger
• a loop amplifier
The various elements are designed to complement each
other thanks to matched acoustical, electrical and
mechanical specifications.
The volume of each microphone/line signal can be
individually adjusted to obtain the required mix; the
mixed output is controlled via the master volume
control and separate high/low tone controls.
The unit is easy to use, and provides a crisp call or clear
music. The mixer also has enhanced features such as
ducking level control, priority, labeling, and setting
indicators.
All Microphone/line inputs can be switched between
microphone level and line level sensitivity. The inputs
are balanced but can also be used unbalanced. Phantom
power can be selected via a DIP switch 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 a PTT
(push to talk). A chime can be configured to precede
an announcement.
• Input 2 can be switched automatically if a signal is
available at the input, for example, if someone
speaks into the microphone (VOX activation).
A telephone/70 V emergency input with VOX
activation is also provided for easy integration with
another PA system or a telephone paging system. It has
its own volume control and overrides all other inputs,
including the call station and inputs 1 and 2.
2.2 Contents of box
The packaging box contains the following contents:
•PLE-10M2-US
• Labels and colored pins for indicating favorite
settings
•Power cord
• Plena Bonus CD
• Mounting brackets (LBC 1901/00)
2.3 The Plena Easy Line Mixer
The Plena Easy Line Mixer is a high performance,
professional public address unit for mixing up to six
separate microphone/line signals, and any one of three
separate music signals. For a schematic overview of the
Plena Easy Line Mixer, see figure 2.1 on the next page.
The unit also has a line output for generic use. 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 (for
example, an equalizer or Plena feedback suppressor) to
be connected between the preamplifier and the power
amplifier stages. A feedback suppressor can ensure
feedback-free, clear speech for all microphones.
Users can create custom labels for inputs, music sources,
and output zones. These labels can be attached to the
special holders at the front of the mixer. Colored pins
can also be inserted at various positions around the
volume and tone dial controls to indicate favorite
settings for a particular application.
Bosch Security Systems | 2008-04 | PLE-10M2-US en
Plena Easy Line Mixer | Installation and User Instructions | Description en | 10
An LED meter monitors the master output before the
zone selection. This signal is also present on the
headphone connector below the output meter.
The output meter and the headphone connector
monitor the call signal if a call is being made, otherwise
the BGM channel is monitored.
The Plena Easy Line Mixer has an input for 24 VDC
backup power, but has no built in 24 VDC battery
charger. However, Power Amplifiers from the Plena
product range have a built in 24 VDC battery charger.
A separate battery charger is, therefore, not required.
The charger charges the battery with a 0.5 A constant
current until the battery voltage reaches 27.4 VDC.
The charger then switches over to constant voltage
charging (also known as float charging).
Note
When using the unit with backup power of 24 V,
make sure that the unit is always powered ON.
When the unit is switched OFF, the batteries will
be drained as this will be regarded as a power
source. Consequently the unit will revert to
24 VDC power from the 24 V input.
