Product description from manufacturer
With just one front speaker and a subwoofer, a dynamic 5.1 surround sound is created by using unique "NIROSON CINEMA 1.1" technology. There is no right, left or rear speaker, but a miraculously simple yet ingenuously designed sound system. The receiver unit is equipped with a DVD player and a full-digital power amp. Two types of model are available: Standard model (STD) which you can experience home theatre sound in reasonable price, and pro model (PRO) which creates more powerful and effective sound from rear. By connecting your TV to either NIRO1.1STD or NIRO1.1PRO, a true home theatre system can easily be enjoyed.
