Product Description
-
Highly flexible stand-alone digital message player
-
Up to 12 messages and 12 trigger inputs
-
Downloads messages from a PC in WAV format
-
Compliant with standards for emergency sound systems
-
Zone control for Plena system preamplifier LBB 1925/10
-
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
