The Speech Leveler is a compander that is optimized for speech audio. It quickly equalizes the difference in speech levels in the room without bringing up noise. If you use AGC with the Speech Leveler, set the AGC Response Time to >2 seconds.

AGC adjusts softer and louder input audio to a consistent level that you select (the target level). The target level range is from -30 to 20dB in 1dB steps. The default target level is 0dB.

Set the Target Level first, then apply the amount of maximum gain that you want the AGC to apply to the signal. Maximum gain range is 0 to 18dB in 1dB steps. The default value is 18dB. AGC occurs after the gain and filter settings in the audio signal path.

The Active Gain meter reflects the overall gain at any given moment. Click the white box next to the meter to enable it.

The Response Time adjustment determines the total AGC engage/disengage response time. The Threshold determines the decibel level at which you want the AGC to engage. Setting the threshold toward the higher end of the scale (near 0) reduces background noise to a greater degree. The Response Time is measured in milliseconds. Target Level and Threshold are both RMS.

P Pwr (Phantom Power)

Phantom Power toggles the phantom power on and off. Phantom power is an auxiliary power source to power certain types of microphones. The XAP 800’s phantom power voltage is 24VDC. Default is On.

AEC

AEC opens the Acoustic Echo Canceller window. To enable the acoustic echo canceller, click Enabled, then select the reference. Any one of the 12 outputs, four expansion bus references, or four virtual references can be selected.

PA Adapt and AEC Reference

If you select an expansion bus reference, the Define PA Adapt/AEC Expansion Bus Ref window opens so you can identify which expansion bus output you want to use as the AEC’s reference. You can also open this window from the toolbar.

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.
