  • 1. 产品简介

    Becke BG-120 是一款中高功率SIP整合式广播功放,作为中型场域通讯系统的运行核心设计。该设备稳定输出120W功率,专为已无法满足区域型80W设备使用需求、但暂未需要工业级硬件超大功率输出的场景打造。它是专业IP音频市场中「恰到好处」的解决方案——具备驱动跨多房间或大型开放空间的大范围扬声器阵列的充足动力,同时保有网络管理式设备的精细操控性。

    BG-130 高保真音质

    BG-120的核心是原生SIP(会话初始协议)终端设备,可直接接入企业数据网络,突破传统模拟广播系统的限制。无需从中央机柜布设专用的粗铜质音频线路至建筑各角落,BG-120支持分布式架构部署,只需接入标准以太网接点,即可成为IP程控交换机或云端电话系统中可远程调度的「扩展设备」。这一特性使其成为现代「智慧建筑」的必备设备,实现语音、数据与安防系统的整合,统一为单一可管理的基础架构。
    BG-120采用工业级机柜式机身,整体设计以散热管理为核心。由于120W的功率输出会产生比入门级设备更多的内部热量,该设备搭载了精密的散热路径与高效能电源模组,确保在学校、企业总部等场景中,即便长时间持续播放背景音乐、进行高频率广播呼叫,也不会出现温控降频或硬件故障的问题。

    2. 核心功能与专业特性

    BG-120在基础IP功放的功能上全面升级,搭载强化型电源管理与高阶音频同步功能。

    高输出效率与70V/100V恒压支持

    BG-120的核心亮点是针对70V/100V恒压扬声器系统优化的120W功率模组,这一设计对中型场域的广播部署至关重要。不同于8欧姆低阻系统会随传输距离衰减信号,BG-120的高压输出技术可实现长距离布线,驱动校园整栋楼层或多层办公楼内的数十台扬声器,且不会出现可听见的音量衰减。相比低功率机型,BG-120在建筑式广播部署中具备极高的灵活性。

    高解析语音与动态范围控制

    音质清晰度是BG-120的核心优势,设备全面支持G.722与Opus宽带编解码器,实现「高解析」语音输出效果。为确保在不同噪声环境下,广播内容仍清晰可辨,BG-120内置动态范围处理功能,让音频输出始终保持稳定——既不会因音量过大产生失真,也不会被办公室背景杂音盖过而无法听清。

    智能任务排程与网络时间协议同步

    BG-120最实用的内置功能之一是自动任务排程器。设备可与网络时间协议(NTP)服务器同步内部时钟,实现高精度的音频任务执行。使用者可直接将MP3或WAV格式的音频文件上传至设备,并设定定时播放,完美适配校园上下课铃声、工厂换班提示音、超市重复播放的促销广播等场景。

    多级优先中断与自动降音逻辑

    BG-120支持最高10级的广播优先级设定,典型配置中,背景音乐为最低优先级,其次是普通广播,紧急警报为最高优先级。当检测到高优先级信号(如SIP紧急呼叫、触发式警报输入)时,设备会通过「自动降音」技术立即压低背景音乐,优先播放紧急信息,直至警报解除后才恢复原有的音频播放。

    远程管理与网络安全加密

    企业IT部门可通过全功能网页管理界面对BG-120进行远程管理,实时监控设备的SIP注册状态、音频输出音量与运行健康度。设备在网络安全层面做了重点优化,支持基于TLS与SRTP的SIP加密,确保广播系统不会被网络中的未授权人员劫持或窃听。

    BG-130 高输出效率


    3. 应用场景

    BG-120的120W功率输出,使其在音频需覆盖大面积区域或多个分区的场景中,具备极强的适配性。

    现代校园与中小学

    在校园场景中,BG-120是理想的「楼栋控制设备」,单台120W机型即可驱动整条走廊连同十间相邻教室的音频系统。其定时排程功能在此场景中不可或缺,可自动实现日常规律的上下课铃声播放。此外,作为IP设备,校长可在办公室通过IP话机发布广播,甚至在巡视校园时通过移动应用程序操作,确保全校师生同步接收同一则信息。

    企业总部与大型开放式办公室

    对数千平的企业办公楼层而言,BG-80机型的音频覆盖效果难以满足需求,而BG-120则能完美适配。它可输出足够的动力,通过背景音乐遮盖环境噪音,打造更私密、舒适的办公环境。当发布「前台有访客」等普通广播时,BG-120能确保茶水间、工程部远端区域、高管办公区等所有位置,都能清晰听见广播内容。

    零售超市与百货商场

    超市属于高天花板、人潮密集的高噪声场景,BG-120具备驱动大量吊挂式扬声器的充足功率,实现双重功能:一方面播放高品质背景音乐提升购物体验,另一方面作为运营工具,发布「价格查询」「五号通道有液体洒落」等实用广播。其可与超市安防系统联动的特性,还能实现自动播放打烊提示、安全警示等音频内容。

    医院与医疗区域

    医疗场景对通讯的要求是即时性与稳定性并重,BG-120是护士站、特定病房的理想音频设备。其120W功率可确保「蓝色代码」(急救警报)等紧急信息,能覆盖辖区内所有病房、走廊与储藏室。高保真的音频输出,让处于紧张状态的医护人员能清晰听懂每一句广播内容,无需重复播放,这在急救现场至关重要。

    中小型交通枢纽

    区域客运站、小型火车站等场景,可通过BG-120实现客流的高效疏导,设备还能与车站的数字显示系统联动:当软件记录到班车到站信息时,可通过API接口触发BG-120自动播放对应的到站广播。其坚固的机身设计,能适配交通枢纽大厅这类灰尘较多的半户外使用环境。

    BG-130 应用场景

    4. 产品总结

    BG-120 可谓SIP音频领域的「全能型设备」。相比入门级机型,其功率实现大幅提升,却又没有超高功率工业级系统的操作复杂性,为有专业级通讯需求的机构,提供了可扩展、高清晰、极高可靠度的解决方案。无论是维持校园的日常运行时序,还是保障繁忙医疗区域的通讯安全,BG-120都能在最需要的场景,输出恰到好处的功率。
