Everything in one unit! Accepts four HDMI inputs with HDMI output to television and subwoofer cable output jack. I ran this with an 80" HDTV and paired it with a B&W DB1. The 5.1 surround sound reproduction is impressive! Plenty of power to fill a large room or add crystal clear sound to a smaller TV environment. I hooked it up to my Oppo BDP-105 and streamed HD movies and digital music with excellent results. No problems with any Blu-Ray disks. Perfect introduction to B&W products. 6/10 for a dent in the right front grill - see photo. This is cosmetic and can probably be repaired. The unit works perfectly. Wall mounting hardware and isolation pins included.
