Yes, a nice start and wouldn't make a bad pre amp / processor if you wish in the future, if it has pre amp outputs which I think it does.

There's an Onkyo 7.1 Channel Home A/V Receiver (TXSR804) running a mixed set of Polk/JBL speakers in the entertainment center at my second job, and it
coasts along quite nicely.

It does have pre-outs, which opens things up for you in the future if you choose the seperates route.

Here's a link for Onkyo's site that offers refurbished units. They don't have any refurbed TXSR804's, but keep an eye on it if that's the route you take:

For the listed MSRP of $999, though, others may have some suggestions on different manufacturers to look at.

Don't be in a hurry; new stuff is coming.

disneyjoe7

I see Crutchfield had it listed for $699 didn't sound to bad to me for that price.

98thumpin

please explain to me the concept of using it as a preamp i mean isnt it an amp and preamp allready, and also can u make a suggestion on a amp to use with it?

ok here goes.

a receiver.. or AVR as they are now called because they include video switching

a receiver has everything all in one unit.
it has a AM/FM tuner, a pre amp and an amp all in one unit. there are hundreds of brands of receivers on the market. all price ranges from about $80 on up to several thousand dollars.

a pre amp is just a one piece that lets you select what you want to listen to.. ie: tuner, CD's, turntable, tape deck, etc. that's all it does.. it does not amplify the signal and you can not hook up speakers to it.

a integrated amp is a pre amp AND an amp in one unit. it's like the pre amp above, PLUS is has built in amps.. so you CAN hook up speakers to an integrated amp.

finally, a power amp.. this can be mono, which is one channel only. Stereo which is two channels, tri amp.. 3 channels, 4 channel amp, 5, and 7 channel amp.

finally you have a stand alone AM/FM tuner. all it does it bring in radio stations. a stand alone tuner in most cases will be better than the tuner built into your recevier.

that should just about cover it..

*side note.. some stand alone pre amps. have tuners in them as well. I forgot that.

AND yes you can use a receiver as a pre amp IF it has pre outputs on the back of it. if not. you can not. period

well put if i use it as a preamp what kind of amp should i use with it ill be driving two polk monitor 70s for my front left and right plus a polk monitor 40 bookshelfs for the rear and a Polk Monitor Series Center Channel Speaker (CS2CH)
and for the sub im going with aVelodyne 12" Subwoofer (DPS-12)

danger boy

you have two options for amps.. get a 5 channel amp. say an Adcom or other brand to drive all your speakers.. OR get only a two channel amp of your choice like Adcom for only your front speakers.. then have your recevier power the center and rears. 5 channel amps are pricey.. well to me they are pricey. LOL

I have an Onkyo TXSR702 and like it. Like mine, the TXSR804 has a 5 band (3 on subwoofer) digital equalizer on each channel. Fun stuff, if you are in to it (autoset or none, if you are not).

Dude, its just like in car audio.

A receiver is like a head unit as in its a horrible power source. Itll work if all youre wanting is some tunes or you live in an apartment or something but in order to get the best sound out of your speakers, you need more power and that means a dedicated amp.

what 2 channel amp wpuld be good to power these i love loud music, and i want to get the best sound out of these speakers i can

MacLeod

Im a little out of my element on this but I have been seriously considering doing away with a 5.1 system once we get a house and instead spend all the money on a set of really good stereo speakers and then get a very stout amp to push them and thie Rotel is what I was looking at.

Rotel aint the most expensive or exotic brand in the HA market but from what I can tell thru reading and talking to people is that theyre still a good quality brand that makes solid products for a decent price.

This 200x2 amp is the one I was most considering along with a pair of RTi10's.

now mac do you know what the price is on that amp its a great looking amp, i looked at adcom but the 200 watt amp is massive, do you know if yamaha, or polk makes an amp good enough to power those monitor 70's? and anyone can answer this for me.

reeltrouble1

nething or anything, hmmmmmmm, saving one letter, makes you a frugal sort I would say.

mac at least it has 200 wpc!!!! get some good wires.

MacLeod

Already got em picked out!!

Radio Shack, here I come!!

disneyjoe7

Just buy what you can afford look forward for the future for any upgrade you would like. What you asked about is FINE go with it, if you can afford something better now add an amp used or look about cables IMHO.

jimi64

Nope-I know nothing.

What i don't get it?

George Grand

That's understandable seeing how you think all the preamp does is switch sources.

does ne one know of a good power amp to power these speakers with, monitor 70's what wattage do i need.

98thumpin

all i want to know is what a good amp for the monitor 70 speakers would be and what wattage i should consider getting?

disneyjoe7

If you got the Coin anything about 125w X 2 is a good place to start. But again what you stated is fine, if coin is a problem this hobby is not cheap so why are we scaring people away?

MacLeod

Read the manual. It will tell ya how much power you should be using. Then go out and find the best quality amp that you can afford that comes closest to matching those power ratings. Nuttin' to it.

98thumpin

ill start looking there in the 125watt range its just hard finding nething sometimes, know of ne brands that make a good 125 or 200watt amp that isnt over around 500 dollers max

98thumpin

Recommended Amplifier Power 20 - 275 w/channel this is what the speakers are rated at

98thumpin

what would a good amp be

disneyjoe7

Audiogon.com is your friend look around see something in your price range post the link here to hear our option if you wish.

98thumpin

a mic














to set up your speakers automatically using tones the receiver generates.
