●Comes with dual-port hub (HUB),Direct access to local area network (LAN)or wide area network (WAN),Can play network audio, accept server and otherIPAccess and control of network devices.
●Powerful network audio playback,Can be used independently on the network,Can be directly played fromIPNetwork audio matrix,IPInternet radio orIPnetworkCDnetwork audio signal.
●With backup constant voltage broadcast input port(100Vinput), can be connected to traditional fixed voltage broadcasting as a backup system. Applicable to college entrance examination/Senior High School/Important broadcasting places such as listening tests.
●defaultIPThe network broadcasting system is the main system, and the traditional fixed voltage broadcasting is the backup system. When a failure in the main system is detected, it will immediately switch to the backup system to ensure that the broadcasting will not be interrupted.
●It has a direct power outage function. When the terminal equipment is powered off, it can automatically switch to the backup system.
●Unique design and algorithm ensureIPThe consistency between the Internet broadcast system and the traditional fixed voltage broadcast system ensures the synchronization of sound after switching.
●The switching speed is fast. When a main system failure is detected, it can quickly switch to the backup system to ensure the continuity of broadcasting.
●The terminal is equipped withMICRO SDCard storage interface and comes standard with a card4Gmemory card.
●Timed songs can be copied directly into storage,It can also be downloaded in batches remotely through the server, and all terminals in the same local area network can complete the download at the same time.
●Timing programs can be downloaded in batches remotely through the server,All terminals in the same local area network can complete the download at the same time.
●Priority can be set for local timing. When set to priority, local timing will be given priority. When local timing is not set to priority, server timing will be given priority. If a network failure or service offline or failure is detected, local timing will be automatically started to ensure that the timing task is foolproof.
●Can accept control from the main control room server,Control of branch control point computer,Moreover, it can also directly accept direct control from internal communication intercom equipment such as network fire fighting matrices and network paging microphones away from the server, and respond more quickly and reliably to emergency tasks such as paging intercom or fire fighting.
●Matchable channel selector,You can choose and listen to multiple audio channel programs simultaneously transmitted, Audio channel programs can come from the server,may also come fromIPNetwork audio matrix orIPInternet radio andIPnetworkCD。
●slightly box is of high qualityMDFMedium density fiberboard is heated and pressed into shape, with built-in fi digital power amplifier and frequency speaker, beautiful sound quality,IPThe integrated design of network, power amplifier and speakers has many advantages such as simple wiring, easy use, and easy maintenance.
●Fixed resistance slightly with auxiliary power amplifier output terminal and capable of being externally connected1Only (4-16ou,10Winternal power).
●Microphone input interface, the microphone has a strong plug function.
●When there is no signal, it can automatically turn into standby state, saving energy and environmental protection.
