The NPX system is an 8x8 audio matrix system that allows you to select and broadcast a variety of source sources in any location. You can select the source and adjust the volume directly through the local controller and audio input device in each output area. In addition, the NPX-8000 provides high-performance S/N and THD, and various DSP functions for tuning the input and output audio to set up BGM broadcasting in places where natural ambience and image are required. 
The NPX system can be used in various places such as exhibition centers, hospitals, hotels, shopping malls, restaurants and cafes where high quality BGM are required. And also it can be used educational facilities such as conference centers, seminar rooms, audiovisual rooms and auditoriums that require rich and clear sound.
