Glossary

Filter A device that passes and blocks audio signals based on user-definable requirements of the system.

•All Pass A filter that provides only phase shift or phase delay without appreciably changing the magnitude characteristic. The filter produces a flat amplitude response. It is useful for matching the delay of two processing channels with different delays.

•High Pass A filter that passes high signal frequencies while attenuating low frequencies. The gain or loss

•High Shelving Provides boosting or attenuation of frequencies above a designated frequency. The transition between the spectrum above and below the designated frequency occurs at a fixed 6dB/octave rate. The gain or loss above the corner frequency is adjustable to +/- 15dB.

•Low Pass A filter that passes low frequencies while attenuating high frequencies.

•Low Shelving Provides boosting or attenuation of frequencies below a designated frequency. The transition between the spectrum above and below the designated frequency occurs at a fixed 6dB/octave rate. The gain or loss below the corner frequency is adjustable to +/- 15dB.

Filter Display A group of nodes plotted on a logarithmic scale. The

XAP 800’s filter display can be accessed through the Inputs 1-8, From Processing, or To Processing windows.

First Mic Priority Increases the audio level required to gate on additional microphones after the first mic is on. This helps ensure that only one mic gates on when a person speaks.

Flow control The regulation of the transmission and reception of data.

Flow Screen The Flow Screen is the main access window for G-Ware features and unit configuration. It also shows a detailed block diagram of the audio signal— presenting a graphical explanation of each stage in the signal path.

Gain The amount a signal is increased over a given reference, typically 0. Normally specified in dB (decibels). On the XAP 800, gain is adjustable from -65 to 20dB (85dB range) in .5dB increments.

Gain Structure The configuration of parameters which define gain adjustment of a signal. The optimal input gain setting is one which provides both an adequate signal- to-noise ratio and reasonable headroom.

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.
