Is this to much power?

Tarter

I found a Rotel RMB-1095 on ebay. Its rated at 5x330 watts at 4 ohms. My LSi series speakers are rated for 200 watts. Here's where I show you how little I know. Will this Amp blow my speakers right off or would it only be if I turned the volume way way up? I've never owned an Amp and I'm not sure how they work.

There is never too much power....muh..hahahahahaha

AndyGwis

No way. The more power, the better amps drive speakers.

LSi's crave power. There are some members here that feed them 500-1000 wpc with great results. Underpowering is more likely to hurt speakers than overpowering.

george daniel

Lsi's love power/high current amps,, the more you give em', the better they sound,have fun

aaharvel

HELL NO! that amp is perfect for those speakers!

polkatese

Rotel+LSi=phoeeyyyy.....almost there!

translation: don't let it slip, BID!

oh yeah, one more thing, welcome!

G-2

No Way, the LSi's love power!

Shizelbs

No, that is not too much power. Its a great pairing actually.

dane_peterson

I don't think you need one more person to tell you "hell no", "LSis love power", "there's no such thing as too much power" etc...

That Rotel is near the top of my list of favorite multi-channel amps. Go for it.

engtaz

No, that's just sweet

Ferres

That's a good buy. The rmb-1095 will be getting a price hike due to the amount of copper in it.

I've used a 600wpc amp with a full LSi setup with no issues.

I think the key here is turning the volume way,way up.You can blow any speaker with any amp by doing so.In the words of good ol' Dirty Harry".....

tonyb is correct. People saying they give their LSis 1000W are saying they are using amps capable of putting out large amounts of power. However, 1000W are not going to the speakers. At ear bleeding volumes, you'll still only put 100-200W into them. But those will be quality clean watts unlike the distorted watts that you can get even with low watt receivers that can blow out your speaks. It's the quality of the power you are getting with the high power amps. If you kept upping the power on a high power amp probably beyond would you could comfortably listen to, you can still damage your speakers.

Power (amplification) doesnt blow speakers! Distortion does...

Rotel makes very solid gear. Orion Bluebook price is $1220 for used. Looks like there are 2 of them listed. Good Luck.

The Rotel has plenty of power and the price is right. For most folks it sounds great. You might enjoy a little better amplifier (more money) as the Rotel can sound a little grainy with a great pair of speakers like the LSi series. It will sound good, but $500 to $1,000 will buy you some smoother sound with a little more lush sound in the midrange.

Please give some examples!!!

schwarcw

Bryston, Parasound, Parasound Halo, Bel Canto, Plinius, PS Audio, Musical Fidelity, low end Mark Levinson, MacIntosh, there is a lot out there. Check Audiogon. I'm not saying the Rotel is bad, I'm just suggesting for a few more bucks you can have a step change in quality. Take your time, research a little, read some of the Forums. You can get a lot of idea and price info. Good luck!

Thanks Carl.

I don't get how the multi channel amps work in HT. Do you run DVD source into processor/preamp and then into amp and on to speakers? I've had amps, but not multi-channel.

Hooking a stereo amp or an amp with more channels into your system is functionally the same. You just have more channels to hook up on the same box. Your processor/preamp can output to the the amps or you can even hook a dvd source up to an amp directly. Depends on what you want to do the final processing before it goes to the amp. Although of course most people plug the dvd source into the processor/preamp.

NeilGabriel

Maybe a better way to ask my question is this...do you use a decoder to take the 2 channel DVDE output and convert to say 5(.1) before sending to amp? I'll see if I can find some connection schematics.

cheddar

Both DVD players and pre/pros have decoders for multichannel sound in them. Again, it depends on which ones you want to use. With SACD and DVD-audio, you have to use the decoder in the player in most cases and use the analog outs to the pre/pro which just passes the signal on to the amp. With movie material, you can use either decoder. If you use the decoder in the player, the signal goes out through the analog outs again with the pre/pro just passing the signal. But if you just pass the digital stream on to the pre/pro via optical, then the pre/pro decodes the multichannel info using its own chips and sends it out to the amp.

engtaz

you take HT receiver or preamp :
Use the pre amp outs for the center,left front,right front, Left side, and right side. 5 outputs to each 5 channels of the amp inputs.
This shows the back of that amp.

NG,

After reading your question again, I think you're asking something else. Multichannel receivers and pre/pros have electronics that take a two-channel source and 'create' surround information from the original two channels. This, of course, is not how the stereo info was originally mastered and will sound inferior to what true multichannel with discreet output for each channel can achieve. DVD movies have discreet multichannel tracks with information for each speaker. However, we're not talking power anymore, so you might want to start a new thread if you want to keep asking these questions.

NeilGabriel

good point(s)...thanks

Underpowering vs overpowering is a misconception based on some fact. Simply giving a speaker a clean signal with low power vs. a clean signal with higher power has no difference. Now if you have a low power amp and drive it into clipping like hell, it'll damage the speaker like hell.

And I'd love to see someone who had an amp that could actually put out 500W continuous FTC rated (5 min sine wave).

The amp isn't going to be sending 330W to each channel continuously. Even with a 20A circuit, its not possible. Also factor in that music and movies are dynamic, and you'll hardly ever see a large amount of power.

Go ahead and get a powerful amp.

I am pretty sure you have a Cinepro amp at Polk Headquarters. (I saw a pic of it from the last PolkFest held there - I think it was running the SRS's)

Hook it up to a nice 240volt line (or 30-40amp 110 volt) and let me know how it goes. I don't know about 6 channels at 500 watts each, but I bet you will get over 500 watts out of a stereo pair.

I would be interested in hearing what you get out of 5 channels continuous....

Michael - I prefer the 120V that the power company provides Just being an anal engineer guy. I don't doubt it could do 500W continuous stereo, but the 5 channels is a bit of a lie. Its something Yammie does well and I've complained about that at length before.
