The XAP 800 is a highly advanced twelveby-twelve digital matrix mixer with 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. 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. In addition, Gentner"s proprietary Distributed Echo Cancellation= makes decisions for each mic individually, based on each mic"s specific conditions. Also, the XAP 800 functions with a network architecture which allows up to eight XAP 800s and up to 16 XAP TH2 Telephone Interfaces to be linked and operate as a single system.
