Couple questions about Yamaha RX-A3060

[lovinthehd]

My XLS Drivecore series amp fans are extremely quiet (fwiw there was another Crown XLS series a few years before that that had noisier fans), think I've read the XLi isn't quite as quiet as the XLS Drivecores but search around for comments....if in an equipment closet won't matter, if several feet away from you likely it won't be noticeable either, particularly when you have the volume up to any appreciable level. My fairly quiet laptop is noisier than my XLS amps are....and even something like air conditioning would likely mask the sound.

I read a comment on amazon its super quiet, (Whisper quiet...even at high levels) to be exact.. but i read somewhere else there is a magnetic field interference if placed the amp and avr beside each other. Is that true?

 

[Hasan Alnajdi]

For future proofing, I suggest either a 2 or 3 channel power amplifier rated 200w per channel into 8 ohms, 300W or more into 4 ohms with 29 dB or higher gain for the front channels.

hello Friend..
I would really appreciate your thought on the crown Xli 800 power amp .. do you have any remarks?

I have the same warning in my XLS manuals; I currently have two XLS amps on the bottom shelf of a rack and just above that (with an mdf shelf in between) is an avr. In my bedroom I have another XLS amp on a shelf below an avr, a glass shelf, not an issue, albeit a little more air space between the two than the other avr. In another room I put a 2ch pre-amp right underneath the amp and no issues. YMMV I suppose but not a problem for me....

I have been thinking where to put the amp for days now.. the only way is to connect the front speaker to hide the wires and according to the attached image (showing my tv and avr setup), can I put the amp under the center speaker beside the avr?or is it too much?

I'd move the center speaker to just under the TV, using a riser if necessary; the center speaker really should not be in a compartment like that as well as it should be centered to the screen and angled towards your ears. Then I'd put the amp where the center speaker currently is (if I'm seeing the correct detail, picture is a bit grainy).

Or, what about hiding the amp in one of the two compartments at either end with the doors covering contents? Or even putting the amp behind the whole thing? One suggestion for turning amp on/off with avr is a smart power strip; the trigger inputs on the Crown amps are a bit different than most so if you're planning on using such (assuming your avr has 12v trigger output) might want to look at what you need.

I believe you first suggesting suits best.. I'll just go to a carbenter to make me a base with the same wood color for the center speaker. But regarding turning the amp on/off, can't I just leave it on 24/7?

The amp is likely fine being left on but I prefer things off when I can easily do so. Carpenter or maybe even Ikea if you have one for something that could serve as a riser....

I'll look around.. thanks alot my friend... you've been most helpful

 

[lovinthehd]

Glad to make suggestions and spend your money

I read in the avr manual that the amp should come with volume bypass control. I can't seem to find anything regarding this on the XLi800.. any idea?

 

[Hasan Alnajdi]

I found this on ikea.. it looks perfect for the center speaker but i gotta check it out in person

They're probably thinking of an integrated amp. You will not have a volume control but rather a gain control; your avr's auto setup routine should help you incorporate it. Depends somewhat on the output voltage from your avr's pre-outs; the amp has a sensitivity setting of .775V or 1.4V and usually the 1.4 setting is sufficient but if the pre-amp output voltage is on the low side from your avr then the .775V setting may be the better one.

ps A good article written by member Wayne Pflughaupt on gain structure is here

A riser isn't hard to construct either, hopefully that will work !

Can you explain more about the difference between integrated/power amps as well as gain/volum control?

this article is way advanced for me .. I tried to read it twice but the vocabulary and the initial and the math.. just too much for me! I feel like Alice in the rabbit whole now

can you please simplify what I got to to do with amp and the avr? I actually now have no idea what to do

Sorry, that is a rather thorough look at the subject.

This one any better? http://www.audioholics.com/audio-amplifier/amplifier-voltage-gain

Here's a simpler explanation https://www.crutchfield.com/S-IFkfdhws18t/learn/setting-amplifier-gain.html


Which speakers are you going to hook up to the power amp? Mains? Are you using any zones? Your manual has some restrictions noted for zone/external amp use from this thread http://forums.audioholics.com/forums/threads/yamaha-rx-a3060-zone-question.107089/

 

[lovinthehd]

Can you explain more about the difference between integrated/power amps as well as gain/volum control?

A power amp basically runs full tilt with some attenuation via the gain control; similar in use to a volume control, slightly different terminology. An integrated amp has inputs for a variety of sources and some processing and switching of those signals and then provides amplification for the speakers; a power amp only amplifies the input signal from one source, some consumer amps have no adjustment for gain or sensitivity to match the pre-amp output ideally, the XLi has an adjustment for both sensitivity threshold as well as gain for fine tuning. Try the articles in the other post I just answered....

I believe thr front speakers are the most suitable.. and am not using any zone.. but i took it as a personal challenge to understand that article.. i just figured out I stepped into a large world by accident and I'm gonna educate my self more

I managed to understand untill part 4.. let me continue reading and then we'll talk


Thanks alot my friend

If you don't have a strong background in electrical theory and the associated mathematics then it will take you much more time to learn enough to understand the Audioholics article linked.

For example, when you see the formula: Voltage Gain (Av) in dB = 20 * Log (Vout/Vin)

To understand what that is about, you can Google dB and Log, and find the following information:

https://en.wikipedia.org/wiki/Decibel

"The decibel (dB) is a logarithmic unit used to express the ratio of two values of a physical quantity. One of these values is often a standard reference value, in which case the decibel is used to express the level[a] of the other value relative to this reference. When used in this way, the decibel symbol is often qualified with a suffix that indicates the reference quantity that has been used or some other property of the quantity being measured. For example, dBm indicates a reference power of one milliwatt, while dBV is referenced to 1 volt RMS.[1]"

Then you Google logarithmic and find:

https://en.wikipedia.org/wiki/Logarithmic_scale

"A logarithmic scale is a nonlinear scale used when there is a large range of quantities. Common uses include the earthquake strength, sound loudness, light intensity, and pH of solutions."

For more detailed information on "logarithsm" read this:

https://en.wikipedia.org/wiki/Logarithm

The "log" (short form of logarithsm), in that formula is to the base of 10, again, the linked article above explained what that meant.

If you search hard enough, you may be able to find articles that gathered up most of the information and definition you need. Otherwise it is indeed a time consuming thing to search out all the information individually yourself.

You may also be able to find articles that tried to explain everything you need to know in non technical kind of language that most people can get the general idea.

In any case, there is always the chance that you may come across information that are simply incorrect, it's the internet after all.
