B series (B800~B2000) IP network amplifier

Product description
Detailed parameters
● With dual port hub (HUB), it can directly access LAN (LAN) or wide area network (WAN), can play network audio, and can access the server and other IP network devices. control.
● Network fault self-diagnosis, network communication status display.
● Powerful network audio playback function, which can be used independently in the network, can directly play network audio signals from IP network audio matrix, IP network radio head or IP network CD.
● Acceptable control of the main control room server, control of the sub-control point computer, and it can also directly accept the direct control of the internal communication intercom equipment such as the network fire matrix, the network paging microphone, and the paging intercom or fire Emergency tasks are more responsive and more reliable.
● Audio channel selection listening function, users can choose any listening in multiple sets of audio channel audio programs transmitted at the same time. Audio channel programs can come from the server, or from the audio matrix or IP network radio head and IP network CD.
● Program on-demand function, which can realize arbitrary on-demand broadcasting of thousands of programs in the server program library. The user can use the first spell letter to make a song query, which is extremely simple and convenient.
● SD card local playback, support for a variety of song formats, high-fidelity sound quality decoding.
● With high-fidelity recording function, the microphone and line signals can be directly recorded to generate MP3 files, and can be called at any time.
● With external control trigger port for recording and playback, the external trigger signal (24V or contact short-circuit signal) can automatically trigger the recording of the recording file stored in the SD card.
● Unique timed task local storage and playback function, timing program and song can be downloaded to the machine, even when the network is disconnected, the server can be interrupted in the state of timing, ensuring that the timing task is foolproof.
● LCD display, with high-precision electronic clock, time display function, and the clock can be automatically synchronized with the server to ensure accurate execution of timing tasks.
● The AC power supply voltage of the power amplifier can be measured and displayed.
● Amplifier fault alarm prompt.
● Unique public address amplifier dedicated circuit design, high reliability and high stability.
