BOSCH LBB 1965/00 Plena Message Manager

Bosch LBB 1965/00 Plena Message Manager 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 Front panel control and remote control The Bosch LBB 1965/00 is a digital message player with a capacity of up to 12 pre-recorded messages with 12 trigger inputs. Ideal for making spot announcements in theme parks, supermarkets etc as well as being suitable for emergency evacuation announcements. The LBB1965/00 can be programmed with up to 12 messages uploaded from a PC and stored on the internal EEPROM. The messages can be any length up to the maximum capacity of 500 seconds across all messages. 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 to 24 kHz with 16-bit word length (linear PCM). This gives up to 500 sec 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 4 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 6-zone LBB 1925/10 Plena System Pre-Amplifier, zone selection can be configured for each trigger input. The message manager communicates this selection to the LBB 1925/10 Pre-Amplifier 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 to 6 are only accessible as contacts on the rear panel to prevent accidental use. The lower priority trigger inputs 7 to 12 are sold separately as trigger switches on the front panel. Integrity and Dependability It can also play emergency/evacuation messages as it fulfills the IEC 60849 standard. The micro-controller continually checks the data integrity of the system, and a watchdog circuit, in turn, checks the micro-controller. The unit monitors the D/A converter with a pilot tone, and the high priority trigger inputs (1 to 6) for cable short circuits and breaks. A 24V 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 It 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 to 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 a headphone jack (sold separately).
