Avr 745 firmware update

Thanks for the reply M8. Have a look at the price in the U. Is there a variable transformer in the amp??? Just thinking of importing one if there was a dual or variable transformer. Best of luck with your choise.

Thanks for the info M8, I would like a new receiver but at times like these you wonder if its worth it for that little bit extra when what you've got does a great job.

I'm trying to convince myself NOT to buy Click to expand You must log in or register to reply here. If someone can provide a good way to test the benefit I have watched the same scenes with and without front height speakers enabled, and I can hear a small difference but not sure about if it's worth it to add these speakers on the wall which doesn't look nice in my living room I don't mean that on some other setups it could sound amazingly good The fact that my living room got a slope with beams ceiling prevent me to install some ceiling speakers which from what I am reading is the way to go to have good 7.

I still have a lot to test, to learn. If you want me to try things, to check stuff, feel free to ask. OldAndSlowDev said:. Up firing with my ceiling would be a disaster for sure. Guys, have you checked this blog:.

I'm very interested to see this play out and resolve. It is a dark time for us in the Audio Hobby right now. Plus, I want to upgrade, myself, but won't until this sh!

The way it calibrated the subs, was awesome Yamaha was never able to do that Although the new A8A is suppose to have that feature now. I am extremely happy with the way the Denon plays the voices, even in loud action scenes.

One of these days though, I'm going to get one of those big Onkyo HT recievers. Where did you get the red information? The Onkyo should have no trouble at all with 4 ohm loads. It has a huge power supply larger than the other receivers mentioned and the other amplifier components aren't lacking either. The Onkyo TX-SR is the only receiver on this list that has THX Ultra II certification which ensures that it will meet certain power requirments in larger rooms, there is nothing that would lead me to believe that this 50 pound receiver could not handle a 4 ohm load.

The Onkyo and Denon for sure feature the latest Audyssey auto-setup program. There is a chance that the Onkyo may have some compatibility issues with HDMI devices, but this may not be entirely reliant on the Onkyo or any receiver listed. Some components with HDMI just don't mesh. Until one standard is found never going to happen then there will always be little hickups with components.

Here is a cut and paste of a recent reply that Alan Loft Axiom resident expert made. Quote Ever since I joined Axiom five years ago, I've been warning against using Onkyo AV models for the 4-ohm M80s based on Axiom customer experience and lab tests by some magazines as the Onkyos either go into severe current limiting when set to 4 ohms producing perhaps 30 watts per channel or less , or they shut down.

The in particular. But unfortunately, I have been following the Onkyo threads at AVS; and even though a person must wade through mounds and mounds of that stinky stuff called BS to find pertinent and reliable information, there is a common trend that I can see quite clearly — the new Onkyo line has too many issues for me to spend my money on. Perhaps there are very low impedance dips, or extreme phase angles? My Teac could drive speakers spec'd like that to fairly intense levels, assuming that they don't have huge swings in impedance which I assume they do given their efficiency, remember the Klipsch RF-7?

Weak amplification paired with very fluctuante loads equals sibilance and wimpy bass. The Axioms probably require a fair amount of control to perform well, more so that most receivers can do. Has the OP considered seperates? Yamaha RX-V paired with an Emotiva power amplifier would be ideal. Yes, maybe a good test that at least Stereophile can do with speakers would be in order to see what that nominal 4 ohms would bottom out at and how wide of a bandwidth.

But, if Axiom's spec sheet is correct, it will do 95 dB spl in room. So, it is not like it needs a lot of power capacity at 4 ohms to be loud. I'm so new to the forum thing, I didn't even know how to subscribe and didn't realize I had all these replies until today. For reference point, I have the Canton Ergo line all the way around and no sub right now. The mains DC's are fairly efficient 89db. Just for fun, I hooked them up to my Kyocera R receiver, rated an honest 65wpc, and I can't turn the volume past 2.

However, this is just a warning and the programmer is probably still uploading the files correctly. We need Arduino to act as a programmer. To do so we just need to upload a sketch already available within the Arduino examples. Therefore from the Arduino IDE:. Double-check the connections as most of the issues will come from a loose wire or wrong pins connected. Without doing so the board cannot be reprogrammed.
