Plena
mono mixer amplifiers have four microphone input, and separate
emergency and music input. Additional functionality like priority
assignment, VOX switching, speech filter and two-tone chimes
are also provided. You can add Plena booster amplifiers to increase
the loudspeaker driving capability.
The dual-zone model directs sound (announcements
or background music) to two separate areas - very useful if
announcements or background music need not to be heard everywhere.
Two front panel switches direct the output to the separate zone.
The Plena mixer amplifiers are available
with a choice of 30W, 60W or 120W rated output power. They can
drive 70V and 100V constant voltage outputs and low-impedance
loudspeakers.
All Plena models have interconnection facilities
for connecting external sound processing equipment as an equalizer
between the pre-amplifier and power-amplifier stages.

The
universal pre-amplifier extends the configuration possibilities
of the Plena family. It offers a choice of mixing, blocking
or serial input priority modes. Each input channel has its own
volume and tone controls, a selectable filter to optimise speech
intelligibility, and direct output.
On the output, it is also possible to override
local loudspeaker volume controls to ensure an important message
gets through
Three input priority modes are available:
mixing mode; blocking mode (first activated channels gets priority
over all others); and serial mode (channel 1 has priority over
2, 3 and 4, channel 2 has priority over 3 and 4, and channel
3 has priority over 4). In mixing mode, each input channel can
be mixed to the master output, irrespective of priority. |

The
Plena multi-zone call system provides dual-channel operation
(call and background music) for six zones. It has two call station
inputs, a selectable filter for optimising speech intelligibility,
and separate volume control and tone control for the speech
and background music channels.
Six levels of priority are available for
music, microphone, call stations, trigger inputs and the emergency
input. Six buttons on the front panel are used to route the
background music to selected zones.
Zone selections for the call channels is
made via the Plena station. The unit has an emergency/telephone
input with VOX. When an emergency audio signal is detected,
it automatically overrules all other inputs. |
