  • 1. 產品簡介

    Becke BG-120 是一款中高功率SIP整合式廣播功放,做為中型場域通訊系統的運作核心而設計。此設備穩定輸出120W功率,專為已無法滿足區域型80W設備使用需求、但暫未需要工業級硬體超大功率輸出的場景打造。它是專業IP音頻市場中「恰到好處」的解決方案——具備驅動跨多房間或大型開放空間的大範圍揚聲器陣列的充足動力,同時保有網路管理式設備的精細操控性。

    BG-130 高保真音質

    BG-120的核心是原生SIP(會話初始協定)終端設備,可直接接入企業數據網路,突破傳統類比廣播系統的限制。無需從中央機櫃佈設專用的粗銅質音頻線路至建築各角落,BG-120支援分散式架構佈署,只需接入標準乙太網路接點,即可成為IP程控交換機或雲端電話系統中可遠端調度的「擴展設備」。這一特性使其成為現代「智慧建築」的必備設備,實現語音、數據與安防系統的整合,統一為單一可管理的基礎架構。
    BG-120採用工業級機櫃式機身,整體設計以散熱管理為核心。由於120W的功率輸出會產生比入門級設備更多的內部熱量,該設備搭載了精密的散熱路徑與高效能電源模組,確保在學校、企業總部等場景中,即便長時間持續播放背景音樂、進行高頻率廣播呼叫,也不會出現溫控降頻或硬體故障的問題。

    2. 核心功能與專業特性

    BG-120在基礎IP功放的功能上全面升級,搭載強化型電源管理與高階音頻同步功能。

    高輸出效率與70V/100V恆壓支援

    BG-120的核心亮點是針對70V/100V恆壓揚聲器系統優化的120W功率模組,這一設計對中型場域的廣播佈署至關重要。不同於8歐姆低阻系統會隨傳輸距離衰減訊號,BG-120的高壓輸出技術可實現長距離布線,驅動校園整棟樓層或多層辦公樓內的數十台揚聲器,且不會出現可聽見的音量衰減。相比低功率機型,BG-120在建築式廣播佈署中具備極高的靈活性。

    高解析語音與動態範圍控制

    音質清晰度是BG-120的核心優勢,設備全面支援G.722與Opus寬頻編解碼器,實現「高解析」語音輸出效果。為確保在不同雜訊環境下,廣播內容仍清晰可辨,BG-120內建動態範圍處理功能,讓音頻輸出始終保持穩定——既不會因音量過大產生失真,也不會被辦公室背景雜音蓋過而無法聽清。

    智慧任務排程與網路時間協定同步

    BG-120最實用的內置功能之一是自動任務排程器。設備可與網路時間協定(NTP)伺服器同步內部時鐘,實現高精度的音頻任務執行。使用者可直接將MP3或WAV格式的音頻檔上傳至設備,並設定定時播放,完美適配校園上下課鈴聲、工廠換班提示音、超市重複播放的促銷廣播等場景。

    多級優先中斷與自動降音邏輯

    BG-120支援最高10級的廣播優先級設定,典型配置中,背景音樂為最低優先級,其次是普通廣播,緊急警報為最高優先級。當偵測到高優先級訊號(如SIP緊急呼叫、觸發式警報輸入)時,設備會透過「自動降音」技術立即壓低背景音樂,優先播放緊急資訊,直至警報解除後才恢復原有的音頻播放。

    遠端管理與網路安全加密

    企業IT部門可透過全功能網頁管理介面對BG-120進行遠端管理,實時監控設備的SIP註冊狀態、音頻輸出音量與運行健康度。設備在網路安全層面做了重點優化,支援基於TLS與SRTP的SIP加密,確保廣播系統不會被網路中的未授權人員劫持或竊聽。

    BG-130 高輸出效率


    3. 應用場景

    BG-120的120W功率輸出,使其在音頻需覆蓋大面積區域或多個分區的場景中,具備極強的適配性。

    現代校園與國中小學

    在校園場景中,BG-120是理想的「棟層控制設備」,單台120W機型即可驅動整條走廊連同十間相鄰教室的音頻系統。其定時排程功能在此場景中不可或缺,可自動實現日常規律的上下課鈴聲播放。此外,做為IP設備,校長可在辦公室透過IP話機發布廣播,甚至在巡視校園時透過行動應用程式操作,確保全校師生同步接收同一則資訊。

    企業總部與大型開放式辦公室

    對數千坪的企業辦公樓層而言,BG-80機型的音頻覆蓋效果難以滿足需求,而BG-120則能完美適配。它可輸出足夠的動力,透過背景音樂遮蓋環境雜訊,打造更私密、舒適的辦公環境。當發布「前台有訪客」等普通廣播時,BG-120能確保茶水間、工程部遠端區域、高管辦公區等所有位置,都能清晰聽見廣播內容。

    零售超市與百貨商場

    超市屬於高天花板、人潮密集的高雜訊場景,BG-120具備驅動大量吊掛式揚聲器的充足功率,實現雙重功能:一方面播放高品質背景音樂提升購物體驗,另一方面做為營運工具,發布「價格查詢」「五號通道有液體灑漏」等實用廣播。其可與超市安防系統聯動的特性,還能實現自動播放打烊提示、安全警示等音頻內容。

    醫院與醫療區域

    醫療場景對通訊的要求是即時性與穩定性並重,BG-120是護士站、特定病房的理想音頻設備。其120W功率可確保「藍色程式碼」(急救警報)等緊急資訊,能覆蓋轄區內所有病房、走廊與儲藏室。高保真的音頻輸出,讓處於緊張狀態的醫護人員能清晰聽懂每一句廣播內容,無需重複播放,這在急救現場至關重要。

    中小型交通樞紐

    區域客運站、小型火車站等場景,可透過BG-120實現客流的高效疏導,設備還能與車站的數位顯示系統聯動:當軟體記錄到班車到站資訊時,可透過API介面觸發BG-120自動播放對應的到站廣播。其堅固的機身設計,能適配交通樞紐大廳這類灰塵較多的半戶外使用環境。

    BG-130 應用場景

    4. 產品總結

    BG-120 可謂SIP音頻領域的「全能型設備」。相比入門級機型,其功率實現大幅提升,卻又沒有超高功率工業級系統的操作複雜性,為有專業級通訊需求的機構,提供了可擴展、高清晰、極高可靠度的解決方案。無論是維持校園的日常運行時序,還是保障繁忙醫療區域的通訊安全,BG-120都能在最需要的場景,輸出恰到好處的功率。

常見問題

什麼是ATEX?


ATEX是大氣可爆物的縮寫,是一套歐盟(歐盟)指令和標準,用於規範潛在爆炸性環境中使用的設備和保護系統。
這些標準旨在確保機械、電氣設備和相關部件在可能存在易燃氣體、蒸氣、霧氣或可燃粉塵的環境中不會成爲點火源。ATEX適用於歐盟境內的設備製造商和向歐盟市場出口產品的製造商。

什麼是IECEx?


IECEx是IEC爆炸性環境中使用設備認證體系的縮寫,是由國際電工委員會(IEC)開發和管理的國際認證體系,旨在促進潛在爆炸性環境中使用的設備和部件的全球貿易。
IECEx系統的核心目標是建立一套全球公認的統一標準和認證程序。這消除了製造商爲不同市場獲得多個單獨認證的需要,從而減少了貿易的技術壁壘,並確保跨地區的產品安全一致性。
