&lt;h4&gt;Effective remote communication through close audio / video integration&lt;/h4&gt;&lt;p&gt;The YVC-1000 features separate microphone and speaker units that smoothly integrate audio and video for natural comfortable remote communication. The high performance full range speaker unit can be placed close to the display so that audio and video from the remote location blend naturally while adaptive echo canceller and other Yamaha sound processing technologies facilitate stress-free conversation.&lt;br /&gt;&lt;br /&gt;&lt;b/&gt;Flexible Connectivity&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;&lt;i/&gt;Fast easy connection to PCs  smartphones tablets and dedicated conferencing systems&lt;/i&gt;&lt;br /&gt;Connect to the YVC-1000 via USB Bluetooth*1 or the audio terminals*2 of a conferencing system for high quality audio in your conferences and meetings. This range of connection options allows you to quickly adapt to a variety of communications environments as well as situations where conferencing might otherwise be difficult due to the lack of a landline or internet connectivity issues.&lt;br /&gt;&lt;br /&gt;&lt;i/&gt;Smooth Bluetooth connection using Near Field Communications (NFC)*3 technology&lt;/i&gt;&lt;br /&gt;Connect simply and easily by placing an NFC-compatible smartphone or tablet over the NFC logo on the top of the control unit while the Bluetooth button is blinking*4.&lt;br /&gt;&lt;br /&gt;&amp;bull; 1 Supports the mSBC codec for transmission of broadband data.&lt;br /&gt;&amp;bull; 2 RCA pin plugs.&lt;br /&gt;&amp;bull; 3 NFC may not function correctly with some NFC-compatible devices.&lt;br /&gt;&amp;bull; 4 If you press the Bluetooth button once it flashes in blue.&lt;br /&gt;&lt;br /&gt;&lt;b/&gt;Excellent Scalability&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;&lt;i/&gt;Connect additional speakers and microphones for larger meetings&lt;/i&gt;&lt;br /&gt;In its standard configuration*1 the YVC-1000 is ideal for small and medium-size meetings. For conferencing on a larger scale external speakers*2 and up to four additional microphones can be added to cover a wider area and accommodate more conference participants.&lt;br /&gt;&lt;br /&gt;*1 The standard YVC-1000 configuration consists of one control unit and one microphone.&lt;br /&gt;*2 You can connect up to two commercially available powered speakers.&lt;br /&gt;     &amp;ldquo;MSP3&amp;rdquo; has been tested and approved as external speaker.&lt;br /&gt;&lt;br /&gt;&lt;b/&gt;User-friendly design&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;&lt;i/&gt;Optimise acoustic settings with a single touch&lt;/i&gt;&lt;br /&gt;The YVC-1000 automatically optimizes its acoustic settings by learning about the acoustic environment of a room as it operates. When time requirements mean that speed is an issue simply pressing the tuning fork button activates the automatic audio tuning function immediately optimizing the acoustic settings for your current environment*1. If any acoustic problems are detected the tuning fork button lights up orange to warn the user. Details on acoustic problems can be accessed through the audio guidance function*2 which also provides announcements for other operations such as when Bluetooth connections have been established.&lt;br /&gt;&lt;br /&gt;*1 Automatically measures acoustic characteristics of the operation space and the placement of microphones and speakers while adjusting the filter settings of the adaptive echo canceller to optimize internal parameters. (This function optimizes settings for the adaptive echo canceller and auto room EQ to correct the difference in delay between the internal and external speakers and correct for the frequency characteristics of the external speaker.)&lt;br /&gt;*2 Supports English Japanese Chinese Korean French Spanish and German. The default setting is English.&lt;br /&gt;&lt;br /&gt;&lt;b/&gt;Convenient Functions&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;&lt;i/&gt;Communicate with various sources simultaneously&lt;/i&gt;&lt;br /&gt;The audio mixing function mixes multiple voice input sources connected to each interface (USB Bluetooth and audio input/output) allowing simultaneous communication over different lines. For example while connected to a web conference via USB you can also include more participants via smartphone using a Bluetooth connection by using the audio mixing function to combine the audio sources.&lt;br /&gt;&lt;br /&gt;&lt;i/&gt;Connect to an external microphone for more flexibility during remote class sessions or seminars&lt;/i&gt;&lt;br /&gt;Equipped with an external microphone input the YVC-1000 is ideal for applications such as remote classes or seminars where a handheld microphone may be preferable. Simply connect an external microphone to output your voice through both the base unit speaker and speakers at remote destinations.&lt;/p&gt;
