Bosch Plena Voice Alarm Controller LBB1990/00

Product Description

• Heart of the Plena Voice Alarm System

• EN 54-16 certified

• Built-in message manager and 240 W amplifier

• Six-zone outputs

• Functions

• The controller has two BGM source inputs and a mic/ line input with configurable priority, speech filter,phantom power and selectable VOX activation

• A total of 16 priority levels can be specified for microphone,call stations and trigger inputs for optimum system flexibility

• The powerful 240 W output section has six transformer-isolated 100 V constant-voltage outputs
  for driving 100 V loudspeakers in six separate zones

• The 100 V-technique reduces line losses on longer distances and provides easy parallel connection of multiple loudspeakers

• All zones may be individually selected from the front panel, and the BGM output level in each zone can be individually set in six steps

• The controller supports A/B wiring section of the Plena Voice Alarm System controller

• The software package also includes many useful programs, such as; MP3-ripping software, a sample-rate converter, various audio and visual tools, and free, MP3-coded music

• The amplifier output is also available as a separate output on 100 V and 70 V

• A separate 100 V call-only output provides addressing for an area where BGM is not required but where priority announcements are

• Six configurable volume-override output contacts are available for overriding local volume controls during priority calls

• Both four-wire and three-wire schemes are supported

• An LED meter monitors the output

• Up to 255 messages can be stored in the internal 16 MB flash ROM, without a need for battery backup

• Each message can have any length within the total available capacity

• Messages and configurations are uploaded from a PC via USB 2 into the memory, after which the unit operates without a PC connection

• The standard WAV-format is used for the messages, and sample rates of 8 kHz up to 24 kHz with 16-bit word length (linear PCM) are supported

• This gives up to 17 minutes of recording time with CD-quality signal-to-noise ratio

• The unit has 12 contact trigger inputs for business and emergency (EMG) calls

• Each can be configured for a message consisting of a sequence of up to eight wave files

• In this way some wave files may be used in various combinations with other messages, optimizing
  flexibility and the amount of storage space used

• Multiple messages can be merged to form one integrated message

• A zone selection, together with this sequence can be configured for each trigger input
