Highly flexible independent digital information player u up to

 12 messages and 12 trigger inputs u can download information in wav format from PC. u meets the emergency broadcasting system standard u lbb1925 / 10 porphyry system preamplifier area control variegate information manager is a high-performance, multi-functional independent digital information player. It is suitable for a variety of applications, from live broadcasting in supermarkets and theme parks to issuing warnings and evacuation information in emergencies. Basic function information built-in 64MB EEPROM memory can store 12 pieces of information, without the need for backup battery for data storage. Each message can be set to any length, but it cannot exceed its total available capacity. Users can use PC to upload information and configuration to information manager through RS-232 port, and then disconnect PC to operate information manager independently. The information is in standard wav format, sampling rate is 8 kHz to 24 kHz, word length is 16 bits (linear PCM). This allows recording time up to 500 seconds and has CD quality signal-to-noise ratio. Using linear PCM instead of compressed audio formats (such as MP3, ADPCM, u-law / A-Law, etc.) ensures high quality playback of all types of audio signals, including sound effects and special sounds such as cue tones. The device has 12 contact closed trigger inputs for broadcasting. Each input can be configured with a sequence of messages (up to 4 messages, selected from the list of available information). In this way, any information can be used in combination, which improves the flexibility and storage space utilization. When used with the six zone lbb1925 / 10 porphyry system preamplifier, the corresponding region selection can be configured for each trigger input. The information manager transmits the selection to lbb1925 / 10 porphyry system front power amplifier through RS-232 interface. If a trigger input is activated continuously, the corresponding information sequence will be played repeatedly. Trigger input trigger input has serial priority, that is, input 1 has higher priority than input 2, input 2 is higher than input 3, and so on. To prevent accidental use, trigger inputs 1-6 with high priority are only provided in the form of contacts on the rear panel. In addition, trigger inputs 7-12 with low priority are provided on the front panel in the form of trigger switches. Integrity and reliability lbb1965 / 00 meets IEC 60849 standard, so it can also broadcast emergency / evacuation information. The microcontroller continuously checks the data integrity of the system, while the monitoring circuit checks the microcontroller. The device uses pilot tones to monitor the D / a converter and monitors high priority trigger inputs (1 to 6) for cable short and open circuits. In case of AC power failure, the 24 V backup battery line with automatic fail over function can keep the device running. Thus, the output power of the next 20 kHz can be connected to the pilot amplifier. When combined with a 20 kHz detector, it also monitors the speakers. Any fault will cause the red LED indicator to light up and activate the fault output contact. The loop device lbb1965 / 00 provides a loop device with balanced XLR and unbalanced lotus plug input and output. With this device, lbb1965 / 00 can be connected to the existing audio link. As long as the broadcast is not played, the signal input is transmitted to the output. When broadcasting is started, the signal input is interrupted and the broadcast information is transmitted to the output. Update information and configuration settings can be uploaded to lbb1965 / 00 Banli information manager through PC. Once the upload is complete, trigger inputs 7-12 can be configured using the switches on the front panel without performing a new upload or even using a PC. In addition, users can use the headphone jack to listen to the information content.
