Communications Systems | LBB 1965/00 Plena Message Manager
The Plena message manager is a high performance, highly
versatile stand-alone digital message player. Applications
range from spot announcements in supermarkets and
theme parks to warning and evacuation messages in
emergency situations.
Functions
Messages
Up to 12 messages can be stored in the internal 64Mbit
EEPROM, without the need for data retention battery
backup. Each message can have any length within the
total available capacity. A PC uploads messages and
configurations via RS-232 to the unit, which can then
operate without a PC. The standard WAV format is used
for messages with sample rates of 8 kHz to 24 kHz with
16-bit word length (linear PCM). This gives up to
500 seconds of recording time with a CD‑quality signal-to-
noise ratio. The use of linear PCM instead of a
compressed audio format, such as MP3, ADPCM and u-
law/A-law, ensures high-quality playback of all types of
audio signals, including sound effects and special tones,
such as attention chimes.
The unit has 12 contact closure trigger inputs for
announcements. Each can be configured for a sequence of
up to four messages from those available. In this way
messages can be used in combination with other
messages, optimizing flexibility and storage space usage.
When used together with the six-zone LBB 1925/10 Plena
System Pre-Amplifier, a zone selection can be configured
for each trigger input. The message manager
communicates this selection to the LBB 1925/10 via an
RS-232 connection. Continuous activation of a trigger
input causes the corresponding message sequence to
repeat.
Trigger Inputs
The trigger inputs have a serial priority, i.e., input 1 has
priority over input 2, input 2 over input 3, etc. The high
priority trigger inputs 1-6 are only accessible as contacts
on the rear panel to prevent accidental use. The lower
priority trigger inputs 7-12 are also available as trigger
switches on the front panel.
Integrity and Dependability
The LBB 1965/00 can also play emergency/evacuation
messages, as it fulfills the IEC 60849 standard. The
microcontroller continually checks the data integrity of
the system, and a watchdog circuit, in turn, checks the
microcontroller. The unit monitors the D/A converter with
a pilot tone, and the high priority trigger inputs (one to
six) for cable short circuits and breaks. A 24 V battery

backup connection with automatic fail-safe provides
continued operation if the mains power should fail. A
20 kHz pilot tone can be mixed with the output signal to
supervise the link to the next amplifier. This also works for
loudspeaker supervision in combination with 20 kHz
detectors. Any failure causes a red LED fault indication,
and activates a fault output contact.
Loop-through Facility
The LBB 1965/00 provides a loop-through facility with
balanced XLR and unbalanced cinch inputs and outputs.
This allows the unit to be inserted into an existing audio
link. As long as no announcements are playing, the signal
input is routed to the output. If an announcement begins,
the input signal is interrupted and the announcement is
routed to the output.
Updating
Messages and configuration settings are uploaded from a
PC. After uploading, the trigger inputs 7-12 can be
configured by using the front panel switches, without the
need for a new upload or even a PC. Message content can
be monitored using the available headphone jack.
