Highly flexible independent digital information player u as many as 12 and 12 trigger input u can be downloaded from the PC WAV format information u meet emergency broadcast system standard u LBB1925/10 spot li system preamplifier zone control spot information manager is a high performance, multi-function independent digital information to offer. It can be used in a variety of applications, ranging from live broadcasts in supermarkets and theme parks to warnings and evacuation messages in emergencies. The basic function information has a built-in 64MB EEPROM memory that can store 12 pieces of information without the need for a backup battery to hold data. Each message can be set to any length, but not exceeding its total available capacity. Users can use a PC to upload information and configuration to the information manager through the rs-232 port, and then disconnect the PC independent operation information manager. The information is in standard WAV format with a sampling rate of 8 kHz to 24 kHz and a word length of 16 bits (linear PCM). This allows the recording time to be up to 500 seconds and has the SNR of CD quality. Using linear PCM instead of compressed audio formats (such as MP3, ADPCM, and u-law/ a-law, etc.) ensures high-quality playback of all types of audio signals, including sound effects and special sounds, such as prompts. The device has 12 contact-closed trigger inputs for broadcasting. Each input can be configured with an information sequence (containing up to four pieces of information, selected from the available information table). With this approach, any information can be used in combination, thus increasing flexibility and storage space utilization. When used with the six-zone lbb1925/10 belle system preamplifier, you can select the appropriate area for each trigger input configuration. The information manager transmits this selection to the lbb1925/10 belle system preamplifier via the rs-232 interface. Activating a trigger input continuously causes the corresponding sequence of information to be repeated. Trigger input has serial priority, that is, input 1 has priority over input 2, input 2 has priority over input 3, and so on. To prevent accidental use, only the high priority trigger inputs 1-6 are provided in the form of contacts on the back panel. In addition, the front panel also provides trigger inputs of 7-12 with low priority in the form of trigger switches. Integrity and reliability lbb1965/00 complies with IEC 60849, so it can also play emergency/evacuation information. The microcontroller continuously checks the data integrity of the system, while the monitoring circuit checks the microcontroller. The device USES A pilot tone to monitor the D/A converter and to monitor the trigger inputs with high priority (1 to 6) to determine whether there is A cable short circuit or A break. When ac power fails, the 24v standby battery line with automatic obstacle transfer function can keep the device running. The 20 kHz pilot tone can be mixed into the output signal to monitor the connection to the next power amplifier. When combined with a 20 kHz detector, this can also monitor the speakers. Any failure will cause the red LED indicator light to turn on and activate the fault output contacts. The loop device lbb1965/00 provides a loop device with balanced XLR and unbalanced lotus input and output. With this device, lbb1965/00 can be connected to an existing audio link. As long as there is no broadcast, the signal input is sent to the output. When broadcasting begins, signal input is interrupted and broadcast information is sent out. Update information and configuration Settings can be uploaded to the lbb1965/00 merry message manager via PC. After uploading, you can use the switch on the front panel to configure the touch input 7-12 without performing a new upload or even using a PC. In addition, users can use the headphone jack to listen for information content.
