3.Leave 1st Mic Priority selected (default) to enable this feature; otherwise, clear the selection to disable it. ClearOne recommends leaving this setting on.

This setting helps maintain maximum audio intelligibility by allowing only one mic to gate on to a participant’s voice. 1st Mic Priority allows more than one microphone to be activated at the same time—it simply restricts mics from gating on to the same audio source. It does this by determining the audio level received by all mics when the first mic is gated on. This audio level is then used as the ambient level for the gating group. If this feature is disabled, usually two or more microphones gate on when only one person speaks.

4.Select last-mic operation from the Last Mic Mode list. There are two options for Internal groups: Last On and Off. If you are configuring Global groups, you can select from the mic inputs assigned to the Global group in addition to Last On and Off.

Last On leaves the mic that was activated last full on until another mic input is gated on. The Input setting allows you to select which mic input the XAP 800 leaves on when all mics gate off. If Off is selected, all mics will gate off when no audio is present. It is preferable in most applications to leave a mic on so the remote participants don’t think they have lost their audio connection. Off is typically only used when you are conferencing multiple sites and need to reduce background noise.

5.Click the Gating Group label to change the group names.

Gain

The Coarse and Fine sliders on the selected input on the Inputs 1–8 window are used to match the level settings for microphone inputs and to adjust input volume level.

•Set the Coarse gain to 55dB for a mic input, 25dB for active equipment that requires an input between mic and line level, or 0dB for a line level input.

•Use the Fine gain slider to adjust input volume level. You can also enter the level directly in the 0.0dB box.

Min/Max limits

Use the yellow and blue upper and lower limit arrows on the Fine gain scale to create minimum and maximum gain level limits. These limits only apply when using relative gain commands; absolute gain commands can exceed the min and max limits. Min/Max limits apply to all serially connected control devices and prevent users from adjusting levels beyond the min/max levels, provided relative gain commands are used.

XAP 800 specifications

The ClearOne Comm XAP 800 is a sophisticated audio conferencing system designed to provide seamless communication in various environments, including conference rooms, boardrooms, and large meeting spaces. Known for its versatility and cutting-edge technology, the XAP 800 is a favorite solution for organizations seeking to enhance their audio conferencing capabilities.

One of the standout features of the XAP 800 is its ability to support up to 16 microphones. This is crucial for larger meetings, ensuring that every participant can be heard clearly, regardless of their location in the room. The device uses advanced audio technologies, including Automatic Gain Control (AGC), which automatically adjusts microphone sensitivity to maintain consistent audio levels. This ensures that the conversation remains intelligible even as participants lean in or shift their positions.

The XAP 800 also incorporates ClearOne’s proprietary Acoustic Echo Cancellation (AEC) technology. This feature eliminates echo disruptions that can occur in audio conferencing, allowing for clear and productive conversations. AEC works by differentiating between direct sound from microphones and echoed sound returning from speakers, ensuring that participants hear each other without feedback interference.

Another significant advantage of the XAP 800 is its integration capabilities. The system is designed to work seamlessly with a variety of third-party audio and video conferencing products, allowing businesses to expand their communication infrastructure without the need for extensive reconfiguration. The XAP 800 also supports USB connectivity, enabling easy integration with PCs and laptops for web conferencing solutions.

The device is equipped with multiple audio input and output ports, providing flexibility in configuration. Users can connect various hardware such as external speakers, additional microphones, and even video conferencing equipment. This adaptability makes the XAP 800 suitable for different setups, whether it’s a simple room with a few microphones or a complex installation with multiple audio and video sources.

User-friendly controls and an intuitive interface make operation straightforward, allowing even those less tech-savvy to manage audio settings with ease. The system is designed to be installed quickly, reducing downtime and ensuring that organizations can get back to effective communication without delay.

In summary, the ClearOne Comm XAP 800 is a powerful audio conferencing solution that combines advanced technologies with flexibility and ease of use. Its features such as support for multiple microphones, Acoustic Echo Cancellation, and seamless integration with other systems make it an ideal choice for businesses looking to enhance their communication efforts.
