observed.
• Warning
Persons can be (severely) injured, or the equipment
can be seriously damaged, if the alert is not
observed.
• Danger
Not observing the alert can result in death.
1.6 Icons
1.6.1 Note icons
The icons used in combination with Notes provide extra
information about the Note. See the following
examples:
Note
General icon for notes.
Note
Consult the indicated source of information.
1.6.2 Caution, Warning, and Danger icons
The icons used in combination with Caution, Warnings,
and Dangers indicate the type of hazard present. See the
following examples:
Caution, Warning, Danger
General icon for Cautions, Warnings and
Dangers.

1.7 Conversion tables
In this manual, SI units are used to express lengths,
masses, temperatures etc. These can be converted to
non-metric units using the following information.
table 1.1: Conversion of units of length
1 in = 25.4 mm 1 mm = 0.03937 in
1 in = 2.54 cm 1 cm = 0.3937 in
1 ft = 0.3048 m 1 m = 3.281 ft
1 mi = 1.609 km 1 km = 0.622 mi
table 1.2: Conversion of units of mass
1 lb = 0.4536 kg 1 kg = 2,2046 lb
table 1.3: Conversion of units of pressure
1 psi = 68.95 hPa 1 hPa = 0.0145 psi
Note
1 hPa = 1 mbar.

2 Description
2.1 The Plena product range
The Plena Mixer Amplifier 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 amplifier also has enhanced features such as
ducking level control, priority, labelling, 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/100 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-1MA030-EU, PLE-1MA060-EU, or
PLE-1MA120
• Labels and colored pins for indicating favorite
settings
•Power cord
• Plena Bonus CD
• Mounting brackets (LBC 1901/00)
2.3 The Plena Mixer Amplifier
The Plena Mixer Amplifier is a high performance,
professional public address unit for mixing up to four
separate microphone/line signals, and any one of three
separate music signals. For a schematic overview of the
Plena Mixer Amplifier, see figure 2.1 on the next page.
Bosch Security Systems | 2007-11 | PLE-1MA030-EU, PLE-1MA060-EU, PLE-1MA120-EU en
The unit also has a line output to add amplifiers for
larger systems that require 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.
Users can create custom labels for inputs and music
sources. These labels can be attached to the special
holders at the front of the mixer amplifier. Colored pins
can also be inserted at various positions around the
volume and tone dial controls to indicate favorite
settings for a particular application.

An LED meter monitors the master output before the
zone selection. This signal is also present on the
headphone connector below the output meter. 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.

four remote locations. The appearance of the wall panel
is matched to the Bosch loudspeaker volume controls.
The music source can be easily changed. The status of
each music source is indicated by an LED.
A standard CAT 5 cable is used to connect the wall
panel to the mixer-amplifier. The maximum distance is
200 m. Please refer to the relevant datasheet for more
information.
Users can create custom labels for the
microphone/line inputs and description of the
music sources. These labels can be attached to
the mixer amplifier at position numbers 2 and 3
(see figure 2.2). Colored pins can also be
inserted at various positions around the dial
controls to indicate the favorite settings for a
particular application. For more information on
inserting and removing pins, see section 4.3.2.
