Plena Message Manager | Installation and Operating Manual |
en | 14
The message manager can be used with all Plena amplifiers via the Cinch output (4) or the XLR Output (6). The
level of the messages can be set via the message volume control (2).
To fully benefit from the features of the message manager in the overall Plena system (e.g. to distribute pre-recorded
messages to pre-programmed zones) the unit must be connected via the system pre-amplifier LBB1925. To do this,
use the RS232 cable and the audio cable supplied.

There are several ways to connect the message manager to the system pre-amplifier:
-
Connecting the Cinch output (4) of the message manager to the Cinch PC Audio In (R) line input of the sys-
tem pre-amplifier, as shown in figure 3.2 (in which the LBB1961 functions as a BGM source).

Connecting the XLR output (6) of the message manager to the points 1 and 3 of the 8-pole DIN socket of the
system pre-amplifier.

3.3 Loopthrough audio connections
Figure 3.3
It is possible to connect the LBB1965 message manager between a mixer pre-amplifier and a power amplifier.
When the message manager is not active, the mixer pre-amplifier is routed to the power amplifier. However, when
the message manager becomes active, this loopthrough connection is interrupted and the message manager is
switched to the power amplifier.
Figure 3.3 shows this configuration example in which the Plena Mixer Pre-amplifier LBB1920 is used with a Plena
Power Amplifier LBB1938. This is a high priority application, as the message manager has absolute priority.
