Setting Up Your Speaker System
This unit has been designed to provide the best sound field
quality with a full seven-speaker system setup, using two extra pairs

Active Servo Processing Subwoofer System, which has its own built-

    I absolutely refuse to read this excuse of the alleged printed word any farther. I am insulted by the fact that the printing is encoded. What kind of machine printed these words? You should be ashamed of yourselves​. Was this an attempt to somehow save money? Did you have any of your own employees try to read this aloud ? Get real!
