Introduction ~ Controls and Connections

Power is supplied through the RS-485 ports to the remote Control Panels from the XAP 800. This power is limited to a total of 300mA at 15 volts for each connector. Over-current protection is provided on the +15V pins to prevent damage in the event of shorting. External power can be provided to control devices when more current is required. See page 92 for maximum cable run distances when using ClearOne Control Panels.

D.Control/Status Ports A and B. These two female DB25 connector are used to connect control devices to the XAP 800. The control devices have access to the command set for the XAP 800 and can be used for common functions such as volume control, muting, preset change, room combining, etc. Devices can be connected to either port.

For instructions on how to program the control and status pins, see the GPIO section on page 77. The default settings allow control and status of inputs, outputs, volume, and presets. These pins are active low. The 32 presets can also be activated via these connectors. For pinout and default information, see Appendix B.

E.Outputs 1–12.These three-pin Phoenix connectors are for connection of twelve line-level balanced outputs with three-pin Phoenix connectors. These outputs are typically used for connection to VCRs, tape recorders, amplifiers, codecs, phone hybrids, and other audio devices. These outputs may be configured to contain any combination of gated and non-gated inputs. The nominal output level is 0dBm.

F.Inputs 9–12.These Phoenix connectors are for connection of up to four line-level inputs. These are typically used for connection of VCRs, tape players, CD players, and other audio sources. They can be routed to any output or multiple outputs. Nominal level is 0dBu.

G.Expansion Bus In/Out. This RJ-45 connector is part of the expansion bus (E-bus), which allows up to eight XAP 800 or XAP 400 units and up to 16 XAP TH2 units to be networked together. The E-bus consists of two buses: one for control, the other for passing audio and mic information (see Control bus, page 7). Using Cat 5 twisted-pair cable, you can separate adjoining units up to 80 feet (24 meters). See the diagram on page 11.

I.RS-232.This female DB9 serial port is for interconnection between the XAP 800 and a PC, modem, or other custom remote controller. For serial protocol, see Appendix B: Connector Pinouts.

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.
