D6648 4×8 Professional Audio Processor

The line array sound field processor is a product that adjusts the main beam radiation direction of the line array sound field through electronic technology and digital processing technology (DSP).It can change the direction of the main beam of the line array sound field under the condition of fixed vertical installation of the line array sound system, and overcome the disadvantages of the line array sound system that is difficult to adjust freely.The D6684  has an excellent adjustable line array directivity function, which can be adjusted in four directions at the same time, so that listeners in the direction of the area can get an excellent listening experience.The D6684 line array sound field processor can flexibly adjust the directivity (vertical radiation angle) of the connected line array speaker by using the web operation page, and the built-in digital equalizer of the line array sound field processor can effectively improve the sound quality.
