Onkyo TX-RZ840 audio issues
I have just last week installed an Onkyo TX- RZ840 receiver and while I haven't checked every possible feature and mode, I have found what I think is an issue with the way the audio is handled/processed. It could be entirely the way I have my system setup or it could be the way Onkyo intended it (which I doubt). I am a long time lurker here, electronic technician (though home audio video is not my specialty), and home theater enthusiast for almost twenty years. Just for some background Onkyo and I believe Marantz both had some hardware issues with previous receivers and I am sure (hoping like hell) those issues have long been resolved. I have the mentioned receiver and it does not process center speaker dialogue properly, whether thru Dish receiver, Oppo Blue ray player, or Roku (Amazon). It doesn't matter what HDMI cables (Monoprice, BlueJeans, or Monster) are used or optical or digital audio cables. This is a 5.1 system. On certain programs and commercials the dialogue is so quiet it is basically inaudible. It happens with every Star Wars movie either Dish, Dvd, or Blue-Ray. It also happens with DTS master 7.1. The only way to get intelligible dialogue during those times is to change the movie/tv mode to mono or all stereo. Nobody wants to do this every time they change a channel and certainly don't want to listen to multichannel in stereo. On Roku, Amazon DD never allows proper audible center in DD mode. My over 12 year Denon handled the up converting, down converting and such without having to change the listening mode. I feel for sure this is a issue that a firmware update could resolve. I believe this unit has only been for sale in the U.S. for less than a month and maybe only for sale in Europe for about two months so maybe enough units haven't been sold yet for people to notice the audio issues. I did contact Onkyo support and they had me try several things hardware and menu configurations but nothing resolved the problem and their support was closed July 4 and have only limited hours on the days they work. If anyone else has these issues please respond and maybe contact Onkyo to see about a resolution. I would much rather update the firmware than ship the unit back and receive an identically flawed unit. There is not an online manual on the U.S. website but there is one on the Europe website.
