which A/V Receiver power all the 5.1 speakers

[jeevanreddy58]

Hi,,
i saw some of the AVR reviews and they stated that many receivers power only front 2 speakers out of 5.1 speakers.. why does it power all the 5 speakers and woofer.

May i know which AV receiver will drive/power all the speakers/woofers in 5.1 system.

Thanks,
--Jeevan

if its only for front 2 then its a stereo amp and not a receiver else its a 2 channel power amp used to power fronts ..while the av receiver is being used as a pre...

as far as standalone receivers go.. none of them will power 5.1 instead power only 5 channel while sub will have its own power supply and independent amplifier and the receiver will give a pre-out for the sub...

if its only for front 2 then its a stereo amp and not a receiver .

Or it may be stereo receiver not AV receiver like this-
NEW Yamaha R S201 200 Watt Home Audio Theater Stereo Receiver | eBay
Check AV receiver and not stereo receiver.

 

[jeevanreddy58]

you mean Yamaha R-S201 powers 5 speakers ??


what r u saying

what is ur suggestion..

which receiver can power all 5 speakers in 5.1 system...

Jeevan Sir - I am sorry but your question is very basic but considering no question is dumb questions, our esteemed forum members are trying to make you understand, but it seems that you are not even willing to do some basic internet research. Hence for your benefit let me try to explain.

AV receiver: Most of the modern AV receivers power all 5 channels. Examples could be Yamaha 373,473 , Denon X500, X1000, Marantz SR5007, NR 1404 etc, Pioneer VSX series. They have multiple connectivity options like HDMI, Optical, RCA etc. Nowadays most of them have HDMI. They can process audio and transfer videos

Stereo Receiver: Stereo receivers are almost same except they drive only two speakers and they are not very commonly used for home theatre purpose due to lack of surround effects provided by AV Receivers (5channels) though they are preferred if music listening is primary with multiple sources

Integrated Amplifier: you haven't enquired about these but this is almost same as stereo reciever purely for music listening though they can also be attached with home theatre use but can not transfer videos. Also as per my knowledge they might have multiple input options but lacks HDMI.

Link mentioned by Spiro sir falls in the second category and clearly states stereo receiver. Oops... forgot to mention Stereo means two channel (left and right).

Appreciate your patience to read through here.

There are plenty in market.Yamaha,Denon,Onkyo ,Pioneer,marantz are the common names.You can go to their websites and click on AV receivers which will show you model no.sDepending on your budget,you can peack one after Demo in local shop.they will power 5 speakers. Subwoofer will be powered one and no separate amp required.

ALL of them.

Give us the link of what you read about some AVR not powering all 5 channels. There in lies the root problem. U have clearly misunderstood something in some article and I am sure forum members can help u understand it better.

Hi,

thanks for Ur explanation
when i read below statements , i thought that it drive only one speaker out of 5 speakers.

what is mean by
115 W per channel (8 ohms, 1 kHz, 0.9% THD, 1-ch driven)
80 W per channel (8 ohms, 20 Hz-20 kHz, 0.09% THD, 2-ch driven)

find above statements in below link.

It is PER channel

So for 5 channel receiver EACH channel gets the power

ALL 5 channel

I think it is simple English...


Have you done other research? Have you visited any showrooms and experience how AVR sound is felt??

as FM mentioned.. you will be getting the mentioned output to each channel

that is maximum power at tap for each speaker is 115 watts at 8 ohm ( impedance). all multichannel AVR's old or new which says 5.1 will support and give power to 5 speakers (fronts, center and surround) for the rest .1 channel which is the sub woofer it will give low wattage signal for which the inbuilt amplifier of the sub woofer will amplify it...

only one channel mean mono...
there are a lot of threads of newbie's which will help you understand the basic terminology. i would suggest you search the forum and also google a few terms for easy understanding.

Well i think most of us haven't understood the OP's predicament.
His point is if AVR drives all 5 channels, then why is power mentioned in 2 ch driven and 1 ch driven - shouldn't it be 5 channel driven. The worry, i presume is, could this mean it drives only 2 channels?
I'll try to explain what i know - experts, pls chip in.
1. A 5.1 AVR drives 5 channels. There is amplification for all 5 channels.
2. At a given instance, movie tracks at the most have sound coming from 2 or 3 channels. Sound recorded into all 5 channels at the same instance, is very rare.
3. All said and done there is a number which is the total power output of AVR. That power is distributed to all 5 channels based on need (the track recorded into that channel). So at a given instance, if at the most 2 or 3 channels are driven simultaneously, what is the use of quoting power rating for all 5 channels driven at the same time - that is the logic of AVR makers.
4. This is actually a clever ploy by the manufacturers. It is a fact that if all 5 channels are driven at the same time, then power per channel will be a very small number. Not just that, most AVRs cannot operate at all by driving equal power into all 5 channels at the same time - they struggle and then go into "protection mode" (basically, shutdown).
5. As i said, in practice you will not get into situation (4) easily. Even if a movie scene had sound recorded into all 5 channels at the same instance, the power required to drive the speakers in the 5 channels will not be the same - ex: surround speaker may just need 10 watt and fronts may need 40 watt each for that instance.
6. Some reviewers actually test by driving all 5 channels simultaneously (ex: soundandvision.com avr reviews) and you find that only few receivers (expensive ones) even operate at that kind of load. See the review of my receiver Yamaha v473 here Yamaha RX-V473 and RX-V573 A/V Receivers HT Labs Measures | Sound & Vision When all 5 channels are driven, it goes into protection mode.
7. Since most receivers are underpowered, some people who need real power go for dedicated power amplifiers like Emotiva XPA-5 along with their AVRs (or pre processors). The emotiva can easily drive good power into all 5 channels at the same time and can bring the best out of most demanding 5.1 HTs in the world.
Hope this helps and didn't confuse you even further

Hemant sir, It is not 115W or 80W per channel for all 5.1 channels.

The op's question is genuine. What does 1-ch/2-ch driven mean?

"what is mean by
115 W per channel (8 ohms, 1 kHz, 0.9% THD, 1-ch driven)
80 W per channel (8 ohms, 20 Hz-20 kHz, 0.09% THD, 2-ch driven)"

The manufacturer has measured the output numbers based on 1-ch or 2-ch connection. The amplifier will not output 115W per channel when all 5.1 channels are on. The 115W rating given is when the amp is driving only one channel. When it drives two channels the power drops to 80W per channel.

When it is driving all 5.1 channels the watts will drop even further may be around 30 w per channel. Manufacturer has not published this for marketing reasons.

Jeevan, hope this clarifies.

I, sincerely, from the bottom of my heart salute all the esteemed FMs who explain things in such a great way......

Hats off guys...

Hats off to you Sash!! Thanks to the OP, i got an answer to a question that wasnt even asked. Why do most rich ppl with very high end HT usually have EMOTIVA amp along with a high end AVR was something i never understood. Now I know.

Thank you for bringing clarity to the discussion...I suspected this all along..I used to look at the AC Power Consumption figure written at the back panel and compare it with the rated RMS power output and never saw any co-relation...so if a receiver has 5 channels, each rated at 125 Watts RMS then it need not mean that they can pump out 125 watts simultaneously...Yes..now its clear. Thank you
