The Yamaha YVC-1000 is a USB conference phone with Bluetooth capability. Featuring separate microphone and speaker units it accommodates small to large conference spaces and rooms with special table configurations, such as a horseshoe, by daisy-chaining up to four additional microphones and using the outputs for two external speakers. The phone can bridge a call from a smartphone connected by Bluetooth to a call from a video conferencing unit or a computer-based UC client connected by USB. The YVC-1000 delivers the most natural and intelligible sound for the room using an auto-tuning function that detects and monitors the acoustics of the environment to optimize sound processing.
