產品亮點

120W輸出,實現更大範圍尋呼與廣播覆蓋

BK-PA120A針對需要比低功率網路功放更充足輸出儲備的專案設計,內建120W高保真功率功放模組,讓系統設計者能在寬敞走廊、大型廳堂、多間教室聯動區域、工廠車間、倉儲區域及商業空間等重視語音清晰度與覆蓋範圍的場景,穩定驅動揚聲線路。

這一輸出規格特別適合需要兼顧中央網路控制與現場實用放大能力的專案。BK-PA120A不只是訊號終端設備,更是尋呼系統中的核心執行單元,為高要求覆蓋區域的日常廣播與營運語音通訊提供充足功率。

網路音訊與功率放大一體化機箱設計

BK-PA120A將硬體級網路音訊解碼模組與功放電路整合一體,簡化安裝與系統整合商的系統架構。產品支援SIP、TCP/IP、UDP、IGMP群播協定,可透過IP網路傳輸16位元立體聲CD級音訊,多數專案中無需額外配置獨立解碼與放大設備。

此一整合設計可簡化機架規劃、布線與維護作業,在學校、商辦大樓、工業場域及公共服務場域等需結構化管理多音訊區域的實際部署中,減少設備數量、簡化故障排查邏輯,讓專案整體佈局更整潔。

對大型尋呼專案而言,真正優勢不只是更高功率,而是在單一工程友善型平台中,強力整合網路音訊接入、輸入彈性與穩定放大能力。

專業機架式規格,適合結構化安裝

標準19英寸2U機架式結構讓BK-PA120A可輕鬆部署於廣播機架、通訊機櫃與整合控制系統。拉絲鋁合金前面板不僅提升設備室專業感,也能與多數音訊、網路及控制設備保持安裝外觀一致性。

這一佈局在重視整潔整合度與功能的專案中尤具價值。校園、工廠、辦公大樓、飯店、交通設施及市政建築普遍需要標準化機櫃安裝,BK-PA120A完全符合此類工程作業流程。

功能特色

彈性輸入設計,支援混合音訊工作流程

BK-PA120A支援2組RCA混合輸出、2組6.3mm麥克風輸入與3組RCA線路輸入,可同時處理多組音訊來源,能搭配本地麥克風、控制室語音輸入、播放設備及輔助音訊源使用,更貼近實際現場運行需求。

麥克風1具強制優先覆蓋功能,當緊急現場廣播需要中斷背景播放或低優先順序音訊時尤為實用。各輸入通道支援獨立音量調節,讓操作人員與安裝人員可輕鬆調校日常廣播參數,無需複雜系統設定。

音訊微調功能,優化現場聲學表現

不同場域具備不同聲學條件,BK-PA120A透過電位計實現低音與高音獨立調節,可依揚聲器佈局、空間大小、安裝環境與播放內容精準微調音訊。在同一專案涵蓋教室、開放走廊、生產區域與辦公區等不同聲學場景時,此功能格外實用。

產品不採用固定輸出特性,而是提供實用的調節範圍,優化語音清晰度與播放平衡。日常語音廣播可透過音調調節強化語音表現,背景音樂播放則能打造更穩定的聆聽效果。

支援多種揚聲器輸出模式,適配多元廣播架構

BK-PA120A支援100V、70V定電壓輸出與4Ω~8Ω定阻抗輸出,可輕鬆匹配不同揚聲線路設計。依專案結構需求,同一機型可同時適用分散式公共廣播線路、長距離揚聲迴路與區域性揚聲配置。

此彈性在複合用途場域尤為重要:校園可在走廊與全樓廣播區使用長距離揚聲線路,工廠可在生產區搭配號角揚聲器、辦公區搭配一般揚聲器,BK-PA120A可在單一部署架構中輕鬆應對此類差異。

網頁管理與智慧網路運行

BK-PA120A搭載高效能ARM架構處理器,支援網頁登入修改參數,讓管理人員與安裝人員在設置、檢查與維護期間更便捷地設定管理設備。在部署多組網路音訊終端的專案中,瀏覽器式設定可節省時間、降低現場調校壓力。

功放同時支援文字轉語音廣播,可應用於定時通知、日常提醒、服務公告與重複性營運訊息,在無需隨時現場尋呼、需自動化提升一致性與反應速度的場域格外實用。

完備保護設計,保障長期安全使用

BK-PA120A具備輸出短路、過流、過載保護,搭配LED警示指示燈,可清晰掌握故障狀態。這些機制在異常條件下保護功放與連接的揚聲迴路,並為維護人員在檢查與故障排查時提供直觀視覺狀態回饋。

產品內建自激保護、過熱保護與開關機衝擊保護,同樣搭載LED警示指示。此類以保護為核心的設計提升日常運行穩定性,讓功放更適合需要持續運轉的廣播環境,將穩定性列為基礎要求而非附加功能。

應用場景

校園與教育場域語音廣播

學校、訓練中心、大專院校與宿舍大樓通常需要小型音訊功放無法滿足的大範圍廣播覆蓋。BK-PA120A結合高輸出功率、網路音訊接收、麥克風接入與彈性揚聲連接,完美適配此類專案,可透過中央網路音訊架構執行定時通知、上下課鈴、行政尋呼和全樓日常廣播。

機架式設計與網頁設定也適合重視結構化維護與長期擴展性的教育場域標準化設備室部署。在大型校園區塊或多棟建築音訊規劃中,本品在功率與管理性之間取得實用平衡。

工廠、倉儲與車間廣播尋呼

工業場域常需要更強的語音放大功能,用於班次通知、生產提醒、安全指引、區域尋呼和事故聯絡。BK-PA120A的120W輸出為大面積或高噪音區域提供充足功率儲備,同時支援網路協定,可整合至現代IP架構尋呼與營運通訊系統。

本地麥克風輸入與強制優先控制功能,可同時支援日常中央廣播與緊急現場介入,適用於工廠、物流區、組裝車間、倉儲與動力設施等通訊需求在常態運行與即時應對間快速切換的場域。

商辦大樓與多區域設施

辦公大樓、飯店、零售場域、醫院與服務複合設施普遍需要網路化公共廣播設備,兼顧日常公告與跨區域有序語音分發。BK-PA120A可作為此類專案的實用SIP功放節點,尤其適合需要大範圍覆蓋或強力揚聲驅動的場景。

多種揚聲器輸出模式支援,可適配長走廊線路、大廳區域、樓層語音覆蓋與複合室內空間,是系統整合商尋求易設定、易維護之高功率機型的理想選擇。

市政、交通與公共服務部署

公共建築、交通設施、服務大廳與基礎建設場域,通常需要結構化網路音訊設備,透過穩定功放平台傳送日常通知、服務提示與現場廣播。BK-PA120A以SIP連接、群播相容、文字轉語音支援與實用機櫃整合能力滿足此類需求。

對此類專案而言,產品價值在於結合高輸出能力與簡潔安裝邏輯。規劃人員可將BK-PA120A作為集中式網路音訊放大節點,無需分散佈置獨立設備,實現更易管理、更規範的工程佈局。

BK-PA120A 產品優勢

BK-PA120A的核心優勢在於專為超越基礎網路音訊播放的專案設計,120W功放級、整合式網路解碼、彈性混合輸入、音調調節、網頁管理、文字轉語音與多重保護機制,使其成為中大型尋呼系統更強效、更易部署的解決方案。

相較低功率機型,本品更適合需要大範圍覆蓋、強力揚聲驅動或在苛刻環境下具備充足運行儲備的安裝場景。對系統整合商、專案承包商與設施管理人員而言,BK-PA120A在音訊性能、網路相容性與安裝便利性間取得實用平衡。
