CHAPTER 4: Advanced Configuration

Presets

Overview

For many audio conferencing applications, a great deal of system flexibility is needed to meet the challenges presented by changing meeting or conference room requirements. These requirements may include changes in muting, audio sources, room orientation, or room combining. And ideally, these changes are made instantaneously—without interrupting or affecting any meetings in progress.

Using presets enables you to accommodate these changing room requirements quickly and efficiently. When you create a preset, you are essentially creating a single room configuration option. Presets can be programmed with a variety of routing, level, gating, delay, filter, and EC reference settings to meet specific application requirements. You can change every unit parameter or a select few depending on your room needs. XAP 800 presets are unique in the sense that they operate independently of other presets in the unit. When a preset is run, only the selected inputs/outputs are changed—all other settings in other presets remain unchanged and are not reset. This means you can change audio routing and configuration settings in a room without affecting settings in other rooms (such as gain). You can create up to 32 presets for the XAP 800.

Presets can be executed in a variety of different ways including the Execute Preset utility in G-Ware, the front panel controls of the XAP 800, RS-232 external control devices, RS-485 control devices (ClearOne Control Panel and XAP IR Remote), logic in/out, and contact closure. You can also create macros which can run multiple presets. These options give you tremendous flexibility when designing your installations and will be described in more detail in this chapter.

Creating Presets

Presets are created in G-Ware using the Preset mode. To switch to Preset Mode, click the Preset Mode button on the toolbar or the Preset Mode button on the Flow Screen. The Preset Mode window (see Figure 4.2) consists of the Preset Configuration Pane (left side of the window), the G-Ware menus and toolbar (although most options are not available because they do not apply to presets), and the Preset Matrix Screen. There is no Flow Screen in Preset Mode since all configurable settings can be accessed from the Matrix Screen.

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.
