Anyone familiar with the Yamaha HTR-5990

[bmccord]

So I have not had this thing for very long and I only have one problem with it. My last HT receiver was a 10 year old JVC unit that you could blow your ears out at 1/2 volume. However, with the yamaha the volume scale goes from -80dB to +10dB or so. BUT, to play loudly, it has to be almost at zero. I can even max it out on some CD's. Is this normal with new-tech receivers? By all means it is loud and clear, but I would think it should be louder at that level. Do I have something set wrong? Not sure, it also gets quite hot and even "locked up" once and had to unplug it and plug it back in. All the wiring is correct, and it runs through the set-up just fine. Kind of curious. I have been told by friends that these typically run pretty warm, and they just stick a little fan behind them to move some air but i am a little worried if this is all she's got...

Well, HTR5990 has 140W x 7. It should be fine with those speakers.

What were you doing when the system locked up? What kind of ventiliation do you have behind your receiver?

you speakers have 89 dB/w/m which is average sensitivity.

Since your receiver is 140 watts per channel.
and it takes about twice the power to increase the volume by 3 dB

so log base 2 of 140 = 7.129 (number of powers of 2 in 140)
7.129 * 3 = 21.388 (total number of dynamic dB)

89+21.388= 110.388 (max volume per channel).

This number is still 5 dB less than the max dynamic range for reference level.

And this number is also just one channel driven. you can expect to cut the wattage in half or even less with multiple channels driven.

so say it's actually 50 watts/channel. you're output is going to be about 104 which is almost half the volume.

so to reach much higher, you will have to buy an external amp.
But running it at 0dB or higher all the time shouldn't be a problem, unless it has poor ventilation.

The secret to getting a reciever to pump out good volume levels is to set the speakers small. You have a subwoofer there, use it. Send all your bass to it, not to you towers. A large speaker is one that can hit to 20hz at -3dB, your can't. This should solve a number of your problems you have been having. One for wire as there will be less power going through it, not that it mattered though. Your subwoofer will also be louder now, as the towers won't be drowning it out.

setting the reciever small lets you use all availbe watts to midrange and treble.

Note: when setting speakers small, you have to set your subwoofer crossover higher so it handle the frequency's missed.

OK, this makes alot of sense. the fronts are set to large but i set everything else to small. I will set the fronts to small and see what it does. As for the ventilation, it sucks, I am currently looking for a new A/V cabinet but as for now, there is only maybe 2" top and sides of air space (nothing stacked on receiver, just shelf above it) and the back is open but damn near the wall and I leave the glass open. I am going to dig out a 6" clip fan from the basement and run that off of one of the outlets on the back so that it just switches on when the receiver does and gets some air moving. As to when it locked up, I was watching a movie (loudly) and went to adjust something and it would not respond. It was still working, but I had to manually unplug it to get it to reset. I was listening at about -2dB. So it is not bad to run it that high (as about +8 or 10 is max) as long as it is properly ventilated? That just seems odd to be running it at damn near 90% volume. Maybe times have changed...

Thanks again

You should never run your receiver at or near "0" for extended periods, which means you are leaving no room for errors - almost no headroom at all if you get a sudden, large peak. You should really look into getting an SPL meter if you don't have one, and calibrate your speaker levels relative to your room before you damage your speakers, IMHO.

As I mentioned in another thread - 5990 is rated at 120x7 @ 8Ohms, .04THD. straight from the receiver's manual.

I agree with t3031999 and Sheep.
Most of your speakers are at 88/89 dB/w/m and at 6ohms.
The receiver will have to work harder to supply the necessary power needed.
Since it has to work harder...if it's not properly ventilated, it'll have problems.

If this is the case, then yamaha's website is wrong. And you really need something more to push those speakers.
After setting your speakers to small, and if it still isnt loud enough, you will probably need a few amps to properly push those speakers.

NS 777's RMS are at 100 Watts, Sensitivity: 89 db
NS 555's RMS are at 150 Watts, 300 Watts, Sensitivity: 88 db.

I used to have to push my speakers hard..then i got a amp and a jblpro speaker for my center.

Thats crazy, a buddy of mine also has the 5760 with the NS777 and they absolutly slam, BUT they are in a 7.5' tall smallish theater room and my room is partially vaulted...

Have you changed your speakers to small yet? did it make a difference?


im just anxious to see if the subwoofer is performing better now

[bmccord]

Yeah, I changed it to small. The sub is MUCH louder, and the fronts are much clearer...gracias

I think this is one of those "chicklet" occasions...hint hint
