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.

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.
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.
