If the same device ID is ✍ assigned to more than one unit on the E-bus network, the Meter LED “+12” will flash

red, the Mic LEDs “1,” “2,” “4,” and “8” will flash green on the affected units. To correct the problem, change the device ID on one of the conflicting units.

You can also use G-Ware ✍ to select a mixer mode.

Device IDs

Once your expansion bus connections are made (and if you have more than one XAP 800 at a site), you need to set up a unique expansion bus device ID number—a network address—for each XAP 800 on the network. As shipped from the factory, all XAP 800s are set to device ID 0.

To assign device IDs

1.Press the front-panel Enter button, then scroll through the menu until the System menu is visible.

2.Press Enter, then scroll through the menu until Device ID is visible.

3.Press Enter, then scroll through the eight (0–7) options. When the desired device ID is visible, press Enter to select it. (You can also set the device ID in the Unit Properties window of G-Ware software see page 25.)

4.Repeat this process for each XAP 800 on the expansion bus network.

Mixer mode

There are two mixer mode settings: slave (default) and master. A master unit is not required in a networked system and in most installations, all units will be slaves. Master units ignore audio from upstream units. This prevents audio from being received from units above the master unit in the network. However, global control of the system is still maintained by whichever XAP 400/800 or PSR1212 unit is connected to a control device through its RS-232 or RS-485 ports. Control is not affected by master/slave designations.

In Figure 2.5, the third unit in the network is a master. It prevents the audio from the first and second units from being passed down the network chain. Likewise the second master unit in the network will not pass on the audio from the unit before it. The third unit provides system-wide control through a connection to its RS-232 port.

To select a mixer mode

1. Press the front panel Enter button and scroll through the menu until System menu is visible. Press Enter to select the menu.

2.

Scroll through the System menu and select Mixer Mode.

3.

Select the mixer setting you want to use.

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.
