The Yamaha YVC-300 is a portable conference phone optimized for use by small groups. Unlike many user-carried devices, the phone delivers ample sound to fill huddle rooms and small conference spaces so users won't find themselves hovering around the phone struggling to hear. The YVC-300 is a perfect choice for organizations that want to offer high-quality group communications solutions without the cost of dedicated equipment for every conference room or open collaboration space. Users can simply borrow a device from an available supply and return it at the end of the meeting. Three connection options make the YVC-300 a versatile conference phone. PC-based audio, video and web conferencing are supported over USB. Analog audio input and output terminals can connect to video conferencing systems. Smartphones and tablets can connect over Bluetooth to use the YVC-300 as the microphone and speaker. The phone also supports fast pairing for NFC-enabled (near field communication) devices. Calls placed simultaneously over any of the connection interfaces are bridged into a single call. The YVC-300 features Yamaha's well-known sound processing technologies that ensure clear, stress-free audio for meetings, including adaptive echo cancellation, background noise reduction and automatic voice detection
