I get this to add a little home Theater pizzaz to we small living room with 42 '' tv . setup be a pain because 1 -rrb- both rear speaker have the internal connector pull out . 2 -rrb- you may have to do something to you source to ensure that dd\/dts come through the optical connection . I have to dig thru the menu of my Sony Blu-Ray player to change the output from hdmus to optical . oddly , audio come out the optical port of the player at all time , but it be not dd\/dts until I make the change . now most of we have 2 source -lrb- cable\/sat box and blu-ray player -rrb- , so the Vizio really need 2 optical input . I confirm my Panasonic tv will not output dd\/dts on the optical port when use the hdmus input , so I can not use that as a switch . none of this be mention in the manual , which also do not have a diagram of the tiny unlabeled front light , so good luck on figure those out . and the manual mention mode call SRS TruSurround and SRS WOW , but do not explain they or when or why you might use they . note that dd\/dts can not be have with the analog stereo input ; make sure you source -lrb- s -rrb- have optical output if you want dd\/dts . that say , this system sound better than the cheap tv speaker -lrb- why do they make tv 's with gorgeous video , but awful audio ? -rrb- and look really spiffy . day 2 : all the button on top of the soundbar quit working . I can still control it with the remote . Stay tune . day 5 : Tech support try a black magic reset consist of remove the power , hold the power button down for one minute , then press each of the other button twice . do not help . but I can make the light go crazy by run my hand over the soundbar , so I think they have a static electricity issue , which likely kill the button . my impression be the Vizio marketing dept override the engineering dept and spend most of the money on the pretty box , but the innards be way too fragile and complicated for the intend use and user . VIZIO ADVICE : add another optical input and beef up the innards ! I will rewrite the manual for you at no charge . buyer advice : buy it locally so you can return\/exchange it easily . I get it on Amazon , so ship it back to they or Vizio be my only option . one month : unit expire . light but no sound . return to Amazon for refund . Life be too short for this nonsense .
