PA-W120W 为何与众不同

具备真正操作灵活性的五区广播

PA-W120W 的核心优势在于五区独立音量控制及每区 100V 定压音箱输出。每个分区皆可独立调整,并按需开关。这使得功放非常适合不同区域需要不同广播时间表、音量等级或操作优先级的场所。

用户无需到处发送相同等级的相同音频,而能更精确地管理覆盖范围。在实际项目中,这有助于将教室与走廊、办公室与车间、公共区域与后勤区域,或是室内区段与室外周界区分开来,在不增加系统复杂度的前提下提供更多控制。

单一平台上的多音源播放

PA-W120W 专为多音源广播而打造。通过广播服务器、网络调度台、对讲电话及手机 App 的协调运作,让用户能够从统一的音频平台管理背景音乐、定时播放、TTS 语音合成、紧急呼叫、电台直播及警报广播。

同时,它还内置 MP3 播放、FM 调谐器和蓝牙功能。这意味着用户可以直接从设备获取更多音源,无需完全依赖外部设备。在许多日常安装场景中,这不仅降低系统复杂度,也提升现场人员的操作便利性。

适用于现代寻呼项目的 SIP 网络能力

PA-W120W 通过内置的网络音频编解码模块支持 TCP/IP、UDP、SIP 及 HTTP 等协议。这使其易于部署在需要集中排程、远程管理和分布式语音通信的现代 SIP 寻呼与 IP 广播架构中。

由于支持 16 位立体声 CD 品质音频传输及 MP3/WAV 兼容性,该功放既能提供清晰的语音广播,也能确保日常音频播放的稳定性。对于必须保持广播清晰度,同时又需支持日常音频应用的系统而言,这一点尤为实用。

为真实广播任务而生

日常广播与紧急寻呼来自同一设备

PA-W120W 的设计可在不需要独立硬件路径的情况下,同时支持日常和紧急通信任务。通过单一集成式功放平台,即可处理定时广播、背景音乐、TTS 消息、紧急寻呼、电台节目及警报广播。

这使其非常适合需要兼顾操作便利性与紧急应变能力的场所。学校可用于上下课铃声与通知,必要时进行紧急语音指示;工厂可用于换班提醒、生产通知与紧急警报;商业场所则可通过同一系统层级管理背景音乐与快速广播响应。

网络中断时的本机操作支持

本功放提供两组 AUX 输入与三组 MIC 输入,具备独立音量及高低音调整功能。更重要的是,它支持网络中断时的本机寻呼。这为 PA-W120W 增添了重要的实务韧性,即使正常的 IP 路径无法使用,基本的寻呼也不会中断。

对许多用户而言,这种本机备份能力是一项重大的操作优势。它有助于维持通信的连续性,并使功放在即使遭遇暂时性网络问题,通信仍需持续的实际安装环境中更加可靠。

比传统功放提供更多价值的功能

网页管理与专用客户端设置

PA-W120W 提供完整的网页远程管理界面,用户可通过浏览器输入 IP 地址访问设备。在管理页面中,操作人员可设置网络参数、管理 SIP 账号、调整音量、进行在线数据包捕获,以及执行在线固件升级。

除网页访问外,也支持通过专用客户端进行设置。此双重途径设置对工程团队和维护人员非常实用,因为它提供了更方便的调试与故障排除选项。功放亦支持 DHCP 与静态定址,以及跨子网搜索与配置,有助于简化在较大网络中的部署作业。

内置 MP3、FM 与蓝牙,使用更灵活

PA-W120W 配备内置 MP3 播放模块,具备 USB 与 SD 卡接口,提供强大的媒体读取能力,并支持 MP3 与 WMA 解码。用户可根据操作需求选择随机播放、单曲重复、文件夹重复及全盘重复等不同播放模式。

此外,还支持五种 EQ 音效,有助于让播放风格适应不同的听音环境与用户偏好。内置的优先播放功能,则可在必要时确保较重要的音频优先播出。内置 FM 调谐器支持实用的广播接收,可存储约 15 至 40 个电台;蓝牙模块则可连接手机、平板及电脑,进行直接无线播放,距离最远可达 20 米,为较小规模的现场应用提供额外便利。

清晰的本机控制,提升易用性

功放采用 128 × 64 图形点阵显示器,为用户提供更清晰的状态查看与功能选择界面。此显示器让本机操作更加直观,对于需要直接日常访问设备功能,而不全然依赖远程平台的安装人员与终端用户而言非常重要。

音频性能、电源设计与可靠性

D 类放大技术与更稳定的输出

PA-W120W 采用 D 类功率放大技术与全环路反馈网络,以降低失真,并在较高输出操作时保持更佳的声音完整性。这有助于功放在跨越多个分区或支持更频繁的广播时,提供更稳定的寻呼与广播性能。

高效电源架构与宽电压支持

采用双 PFC 开关电源技术,提升整体效率并降低不必要的电流消耗。支持 AC90V 至 AC265V 的宽泛输入电压范围,使其更能适应不同地区的电力状况,并有助于简化跨多样化地点的部署。

智能散热与低待机功耗

智能温控散热系统根据运行状况自动调节散热。内置风扇设计可在相对低噪音下高效散热,帮助功放维持稳定,同时不为环境增添不必要的干扰。当无信号时,可自动进入待机模式,待机功耗控制在 10W 以下,有助于降低长期能源浪费。

工程部署的保护与扩展性

多项保护功能,运行更安全

内置软启动、直流保护、短路、过热、过载及限制器保护等多项智能保护功能,可提升系统安全性,并降低异常运行条件下功放受损的风险。电平、保护及待机指示灯方便技术人员进行日常检查;同时具备 4KV 雷击浪涌保护,在必须严肃对待电气干扰的现场安装中提供实质价值。

通过辅助输出便捷扩展

设备提供两组辅助音频输出,可通过标准 RCA 接口连接外部功率放大器进行扩展。这使得接线更为便利,并为系统设计者在日后需要更大输出功率或更广区域覆盖时,保留了扩展空间。由于 PA-W120W 采用全数字设计且兼容多种网络架构,扩展时不受位置限制,经常可直接沿用现有网络基础设施,降低部署成本与长期维护工作量。
