JBL VM-300 Wireless Mic

VM300

Wireless Microphone System

VM300 is the first dual channel UHF wireless microphone system designed to complement the acclaimed JBL karaoke sound. The system includes one SR300 receiver and two HT300 hand-held transmitters and provides the ultra-clarity, rich vocal and interference-free transmission needed in karaoke entertainment or professional sound applications.

无线麦克风系统

VM300是首款为JBL娱乐定制的超高频无线麦克风系统。该系统包含一台SR300接收机与两只HT300手持发射器，提供KTV娱乐或专业级扩声应用所需的纯净自然音质、饱满厚实人声与无惧干扰等特质。

Specially-tuned JBL KTV sound
Acoustically, the VM300 system is specially tuned to complement the proven JBL KTV sound, in particular the JBL Entertainment karaoke loudspeakers. When collaborating with these acclaimed speakers, VM300 is able to deliver easy and smooth singing experience and unexpected sound performance - rich vocal, transparent mid-range and subtle high notes – whether you croon or belt out.

JBL娱乐定制音色

VM300根据JBL的经典音质要求精心调校，匹配JBL音箱产品进行调试，以营造非凡愉悦的歌唱体验。VM300特别强调了易唱性与入喉感，人声清晰饱满厚实、中频圆润通透、高频细腻柔美，无论低吟浅唱或引吭高歌，皆有不俗表现。

Reliable Performance
Trouble-free performance is one of the aspects any karaoke operator may look into when selecting a wireless microphone system for their multi karaoke rooms. The VM300 system transmits signal in UHF band of 640 MHz – 690 MHz and offers 200 channel/frequency selection, as a result, interference is not a concern while multiple VM300 systems are operating simultaneously in different rooms.

卓越性能值得信赖

当需要使用多套无线麦克风系统时，抗干扰性几乎是必须考察的性能指标。VM300工作在640 MHz – 690 MHz超高频段，提供200个频道/频率选择，即使多套VM300系统同时使用，也无需担心干扰问题。

Simplicity Beyond Expectation
The VM300 system offers a wide range of features and aims to make the setup and use quick and easy. Preset module selects a pair of frequencies or channels for both Ch-A and Ch-B. Auto Scan examines for unused frequencies/channels automatically without the need of manual search. Shake to Sync works in the brand of 2400 MHz – 2483.5 MHz and allows concurrent frequency synchronization of two HT300s. Auto Mute, Auto Wakeup, Auto Sleep ensure energy saving and reduce the noise impact to the system.

简捷灵活

VM300系统提供完善的功能，可有效提升系统设置与使用的快捷度与灵活性。预设模组可同时为通道A与通道B选取预设的频率或频道。自动扫频可实现一键搜索环境中的干净频点。Shake to Sync采用2400MHz – 2483.5 MHz的工作频段，可同时为两只HT300进行对频操作。智能静音、智能唤醒、智能休眠等功能可节能省电，有效减少环境中的噪声对系统的不利影响。
