CHAPTER 1: Introduction

Product overview

Congratulations on purchasing the XAP 800, a highly advanced twelve-by-twelve digital matrix mixer with Gentner® Distributed Echo Cancellation®, noise cancellation, and audio processing. It uses an internal macro language and 32 user- definable presets to quickly adapt to a variety of teleconferencing and sound reinforcement applications such as distance learning, teletraining, telemedicine, courtrooms, conference rooms, boardrooms, hotels, and houses of worship.

In its most simple form, the XAP 800 is a mic mixing matrix. As such, all mic mixing parameters can be customized and any input or combination of inputs can be routed to any output or combination of outputs, with attenuation adjustments at each cross point. This allows great flexibility in accommodating a variety of applications and requirements.

The XAP 800 features numerous functions which greatly enhance its performance and flexibility. For example, it can gate mics on and off when the sound within a mic’s acceptance pattern reaches a certain level.

The XAP 800 monitors each mic independently, observing ambient levels and making decisions based on each mic’s environment. Thus, the input for a mic located in a highly reverberant part of a conference room is gated, mixed, and processed to compensate for the changes in that area and reduce echo and noise. This improves audio quality and decreases the possibility of feedback.

The XAP 800 facilitates local and remote PC setup and diagnostics, logic outputs, and automatic gated mic operation. Mic inputs can be individually customized to gate on and off as you want, while automatic gain control keeps the overall sound level consistent. Eight of the 12 channels can be configured as an automatic microphone mixer.

Adjustments in routing, level, and other functions can be made through presets activated through a closure on the rear panel, an RS-232 serial interface, or a control panel on the expansion bus data channel.

The XAP 800 features eight audio processing blocks, each with 15 filters. Each filter can be configured as a parametric equalizer, high pass, low pass, CD horn, high shelving, low shelving, all pass, or crossover. This allows you to tailor the XAP 800’s audio response to optimize the audio quality and fidelity characteristics of a wide variety of sound reinforcement systems.

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.
