DescriptionThe Wheelock AMT multitone horns and horn strobes provide the industry with a UL Standard 1971 and UL Standard 464 combination audible/visual device that simplifies installation and offers three (3) distinct prioritized audible signals from three isolated inputs. Priority (1) will override all other commands upon activation.The AMT offers a choice of eight (8) self-prioritized soundcombinations for suppression releasing systems, combination security and emergency evacuation systems and high risk installations as well as many other applications.The AMT Strobes are designed for ADA applications while meeting or exceeding the latest requirements of NFPA 72 (the National Fire Alarm Code), ANSI 117.1 (the American National Standard For Accessible and Usable Buildings and Facilities) and UL Standard 1971 (Standard for Signaling Devices for the Hearing Impaired).Each AMT Audible and AMT Strobe appliance has two user selective sound output levels: STANDARD dBA and HIGH dBA. The AMT Audible provides 12VDC or 24VDC operation, filtered or FWR. The AMT Strobe Electronic Appliances operate at 24VDC and may be used with filtered or unfiltered (full-wave-rectified) input voltages. Separate supervised sets of input terminals are available for each prioritized input. Jumper plugs are provided to enable both tone and strobe to operate simultaneously for all inputs.The AMT multitone strobe appliances are UL Listed for indooruse, wall mount, under Standard 1971 for Signaling Devices for the Hearing Impaired and Standard 464 for Audible Signal Appliances,and use a Xenon flashtube with solid state circuitry enclosed in a rugged Lexan® lens to provide maximum reliability for effective visible signaling.All models may be synchronized using the Wheelock DSM Sync Modules, Wheelock Power Supplies or other manufacturers panels incorporating the Wheelock Patented Sync Protocol.Wheelock AMT Multitone Horns andHorn Strobes2Technical Data TD450153ENEffective February 2019Wheelock AMT Multitone Horns and Horn StrobesEATON Features• Approvals include: UL Standard 1971 and UL Standard 464, FCC, ULC, Factory Mutual (FM), California State Fire Marshal (CSFM), See approvals by model in Specifications and Ordering Information • Compliance with RFI limits in FCC Part 15, Class B forcompatibility with sensitive detection and communication circuits • Designed to meet or exceed NFPA/ANSI Standards and ADA Accessibility Guidelines.

汽车音响调音技巧进阶分享汽车音响作为提升驾驶体验的重要组成部分，其音质的好坏不仅取决于音响设备的品质，更关键的在于调音的技巧。
对于音响爱好者来说，掌握一些进阶的调音技巧，能够让汽车音响发挥出更出色的效果。
首先，我们要明确汽车音响调音的目标，那就是实现清晰、平衡、逼真的声音。
清晰意味着每个音符都能清晰可辨，没有模糊或混杂；平衡则是指各个频段（如低频、中频、高频）的声音比例协调，不会有某个频段过于突出或缺失；逼真则是尽量还原音乐原本的声音特质和现场感。
在开始调音之前，确保车内环境的准备工作到位。
关闭车窗和车门，以减少外界噪音的干扰。
同时，检查音响设备的安装是否稳固，喇叭的位置和朝向是否合理。
如果喇叭安装不当，可能会导致声音的反射和散射，影响音质。
接下来，我们来谈谈频率调整。
汽车音响系统通常有低音、中音和高音的调节选项。
低音部分控制着音乐的节奏和力量感，如果低音过重，会让声音变得浑浊；低音不足，则会使音乐缺乏动感。
适当增加低音可以增强音乐的氛围感，但要注意不要过度，以免掩盖了中高音的细节。
中音部分是人耳最为敏感的频段，它决定了声音的清晰度和可懂度。
如果中音不足，声音会显得空洞；中音过多，又会让人感到刺耳。
对于大多数音乐来说，中音的调整至关重要，需要仔细聆听，找到一个最舒适的平衡点。
高音部分则赋予音乐明亮度和通透感。
高音不足会使声音显得沉闷；高音过多则可能会带来尖锐和刺耳的感觉。
在调整高音时，要注意保持声音的柔和与自然。
除了频率调整，还有相位调整。
相位是指声波的起始点，如果喇叭之间的相位不一致，声音会出现抵消或叠加的现象，影响声音的定位和层次感。
通过调整喇叭的相位，可以使声音更加聚焦，舞台感更强。
在进行调音时，不要仅仅依赖于音响系统的预设模式。
虽然这些预设可能在一定程度上适合某些类型的音乐，但往往无法满足个人的独特需求。
最好的方法是使用专业的测试音频，如粉红噪声、白噪声等，来辅助调整。
音量平衡的调整也不容忽视。

汽车流媒体使用说明随着科技的发展，汽车流媒体已经成为了现代汽车中不可或缺的一部分。
通过汽车流媒体，驾驶者可以随时随地享受音乐、收听新闻、导航等各种娱乐和信息服务。
本文将为大家详细介绍汽车流媒体的使用方法和注意事项。
一、连接流媒体设备将您的智能手机或其他流媒体设备连接到汽车的音频系统。
通常情况下，您可以通过蓝牙或USB接口来实现连接。
蓝牙连接通常更为简便，只需在手机设置中开启蓝牙功能，并在汽车音频系统中搜索并配对设备即可。
USB连接则需要将手机通过USB线缆与汽车音频系统连接起来。
二、选择音频源在连接成功后，您可以在汽车音频系统的界面中选择音频源，如FM、AM、USB、蓝牙等。
选择蓝牙音频源后，您可以通过流媒体设备上的音乐播放器来选择您喜爱的音乐。
如果您选择了USB音频源，您需要将音乐文件存储在U盘中，并将U盘插入汽车音频系统的USB 接口。
三、播放音乐在选择好音频源后，您可以通过汽车音频系统的界面来控制音乐的播放。
您可以通过触摸屏或旋钮来切换歌曲、调节音量、暂停/播放等。
有些汽车音频系统还支持语音控制，您可以通过语音命令来控制音乐播放。
四、收听新闻和广播除了音乐，汽车流媒体还可以提供新闻、广播等各种信息服务。
您可以在汽车音频系统的界面上选择相应的功能，如收听电台、播放新闻等。
有些汽车音频系统还支持预设电台，您可以将您喜欢的电台预设在汽车音频系统上，方便您随时收听。
五、导航功能现代汽车流媒体还提供了导航功能，让您在驾驶过程中更加便捷。
您可以在汽车音频系统上选择导航功能，并输入您的目的地。
汽车音频系统会根据导航数据为您提供路线规划和导航指引。
有些汽车音频系统还支持实时交通信息，可以帮助您选择最佳路线。
六、注意事项在使用汽车流媒体时，有一些注意事项需要我们遵守。
首先，确保您的流媒体设备已经下载了最新的软件版本，以保证流媒体功能的正常运行。
其次，不要在驾驶过程中分散注意力，尽量在停车时进行操作。
最后，根据当地的交通法规，合理使用汽车流媒体功能，避免影响驾驶安全。
汽车喇叭的调整及保养
喇叭的调整：
1、音调的调整：调整时应注意铁心与衔铁四周的间隙要均匀、平正、不能歪斜，否则工作时容易发生互相碰撞，使喇叭产生杂音。
2、音量的调整：喇叭音量的大小与通过喇叭线圈的电流大小有关，通过的电流越大，音量就越大，反之音量就小，调整触点压力可以改变音量。
喇叭音量和音质的调整是互相关联的，因此需要反复调整才能获得最佳声音。
喇叭的保养：
（1）经常保持喇叭外表清洁，各接线要牢靠。
（2）经常检查、紧固喇叭和支架的固定螺钉，保证其搭铁可靠。
（3）喇叭的固定方法对其发音影响较大。
为了使喇叭的声音正常，喇叭不能做刚性安装，因而固定在缓冲支架上，即在喇叭与固定支架之间要装有片状弹簧或橡皮垫。
（4）经常检查发电机输出电压。
电压过高会烧坏喇叭触点，电压过低（低于喇叭的额定电压）喇叭将发出异常声音。
（5）洗车时，不能用水直接冲洗喇叭筒，以免水进入喇叭筒而使喇叭不响。
（6）在检修喇叭时，应注意各金属垫和绝缘垫的位置，不可装错。
（7）喇叭连续发音不得超过10s，以免损坏喇叭。
现在市场上经营汽车音响设备的商家特别多，为了避免买回一套假冒伪劣产品，最好要看该商家是否拥有该种品牌音响设备厂家授权的指定代理许可证，有无售后服务能力和质量三包的承诺措施。
解决汽车音响的养护与故障排除问题，在选购音响时要注意所选音响品牌在当地是否有专业认证的售后服务维修站。
比如富声音响这样的具有完善售后服务的音响品牌，才能保证爱车的音响在万一出现故障时得到专业、方便的维修服务。

四、常见问题解答1. 为什么无法连接蓝牙？答：请确认您的蓝牙设备已开启，并且处于可被发现状态。
驾驶时如何正确使用音响和娱乐设备驾驶时正确使用音响和娱乐设备对于提升驾驶乐趣、缓解长时间驾驶的疲劳感具有重要作用。
然而，错误操作将会对驾驶安全造成威胁。
因此，驾驶者在使用音响和娱乐设备时需遵循以下几点指南。
一、保持手眼并用在驾驶时使用音响和娱乐设备时，首要的原则是保持手眼并用。
驾驶者需要了解并掌握车辆操作的基本技巧，例如调节音量、切换音频来源等。
在驾驶过程中，应通过仪表盘上的功能按钮或设置好的方向盘控制按钮来操作音响设备，而非通过触摸屏幕。
这样能够使驾驶者的注意力集中在前方道路上，提高驾驶安全性。
二、预先设置音响设备在行驶前，驾驶者可提前设置音响设备以避免在行车过程中分神操作。
例如，选择好喜欢的音频来源、调整合适的音量大小等。
此外，可以通过设备的蓝牙连接功能将手机与音响设备相连，以便接听电话或播放音频文件。
这样，驾驶者在行车过程中只需简单操作方向盘控制按钮即可实现通话或切换歌曲，无需分神操作。
三、合理控制音量大小在驾驶过程中，音量过大可能会影响到外界声音的感知。
正常来说，驾驶者应将音量控制在较为适中的范围内，既可欣赏到音乐的魅力，又不会对交通声音产生干扰。
此外，驾驶者应避免频繁地打开、关闭音响，以免频繁转移注意力，降低驾驶安全。
四、合理选择音乐类型在驾驶时，选择适合驾驶场景的音乐类型也是非常重要的。
例如，驾驶在高速公路上时，选择节奏明快、旋律鲜明的音乐将会带来更好的驾驶体验；而在城市交通繁忙的路段，选择轻柔舒缓的音乐则能帮助驾驶者放松心情，缓解疲劳感。
驾驶者应根据行车环境和自身喜好来选择音乐类型，以保证安全与舒适。
五、避免过度沉迷娱乐设备尽管音响和娱乐设备能够为驾驶者提供愉悦的驾驶体验，但驾驶者必须要警惕过度沉迷娱乐设备带来的风险。
沉迷于音乐或游戏可能会导致驾驶者分神，无法及时回应交通情况。
驾驶者应时刻保持警觉，合理使用娱乐设备，避免过度依赖，以确保驾驶安全。
六、维护音响设备的正常运行驾驶者在使用音响设备时，应定期对设备进行检查与维护，确保其正常运行。
