Product Description
Yamaha RX-V665BL 630 Watt 7-Channel Home Theater Receiver

Just wanted to let everyone know, that although this is a new model receiver Yamaha left out assignable audio and video inputs. I just got off the phone with Yamaha pre sale support and they confirmed this on the models 465, 565, 665, 765, no assignable inputs. We get a receiver that finally has 4 HDMI inputs and HDMI pass through, but no asignable inputs. In other words you are stuck with the arrangement on the back panel. No way to assign optical/coaxial/analog audio inputs to a different video source or vise versa. I was ready to purchase one of these and I’m glad I called first. To bad, what a let down.

DO NOT BUY YAMAHA RECEIVERS! Yamaha has really screwed up by not making a similar unit (rx-v465) compatible with all cable box providers!!!
The receiver worked fine at the beginning (a few weeks). Then the video starting cutting out for about 2 seconds at a time (HDMI goes through the receiver and then to the TV). The audio also cuts out when this happens. There isn’t a pattern, sometimes everything works for a day, other times it will cut out 5 times in 10 minutes.
I’ve updated the firmware for the unit using the yamaha website (august firmware update). This has not fixed the problem.
My cable box is a Verizon HD FIOS box with DVR. I never had this problem before when I used the Verizon TV box with the TV (before using the Yamaha receiver). It’s been the interaction of the receiver with the DVR. I don’t blame Verizon. It’s the responsibility of Yamaha and those who build receivers to make them compatible with major cable providers.
Please send Yamaha a message about taking responsibility for making sure their receivers WORK with other equipment! Please don’t buy Yamaha unless you want to gamble on whether it will work with your cable box!

I bought this when I got my first BluRay because my Denon had run out of HDMI in ports. Now after many dollars spent on cables, dvd players, and bluray players I am ready to pitch it off a bridge. Absolutely every thing I put in any of the hdmi in ports gives me an “invalid signal” error on my TVs both LG 42in 1080. The only thing I can use it for is audio using the (thank god Yamaha still puts them in for the time being) two digital audio inputs. I use the toslink for the LG bluray and coax for the Sony DVD changer. I don’t know if anyone else is having this problem, I guess not since there are no reviews about it. But “buyer beware” go to an electronics store with a generous return policy and try it at home. I wish I had.

I needed a second receiver for my kids tv and I didn’t want to spend a ton of cash. I found the Yamaha RXV665 at Electronics Expo and saved $162.22 and the shipping was free! My needs were for a good 7 channel receiver for movies and their game system and I really didn’t want to get a cheap receiver that would die in less then a year. The 665 may not be as good as my Pioneer Elite but it is a well built and for $317.72 shipped it does a far job.
I’m using a old pair of JBL speakers with a Velodyne VX10 Subwoofer and it does a good job on movies and the video games sound great. The coupon I used at checkout was WS901X5750(it’s kind of crazy, to see the discount you have to go all the way to the end of the check out to see the discount). If your looking for a solid receiver at a great price check out Electronics Expo and take a look at the RXV665 and don’t forget to use the coupon!

So, overall I’m really happy with this receiver – it does just about everything they promised it would, and it sounds spectacular combined with the Polk speakers I bought to go with it.
But….
One of the reasons I bought it was the promise that I could seamlessly connect all my video devices and it would convert them all to HDMI – so that I wouldn’t have to set the TV and the amp whenever I wanted to watch something. This turned out to work well for my HDMI cable box and PS3, and for my component output DVD player – but it took most of an afternoon to figure out how to get both a picture AND sound for my daughter’s Nintendo Wii. It seems that because of the way the inputs were designed, the picture was on source “AV1″ but the sound was on “AUDIO 1″.
Eventually, I found a loose piece of paper in the box the amp was shipped in telling me that I could use the on-screen set up interface to map the video output from “AV1″ to the “AUDIO 1″ mode, so now, when my daughter wants to play Wii, she pushes the “AUDIO 1″ button….
Again, overall the amp is great, but the setup can get convoluted if you want to use it with non-HDMI gear.
