Can I use a Home Theater Receiver instead of ProAudio AMP?

    I'm about to purchase a Samson servo 120 amp to power my Samson Resolv65 home studio monitors.

    I thought it might be smarter for me to purchase a Home Theater Receiver that can also be used to listen to radio & connect it to my Home Stereo system. (just kicking ideas around before I buy)

    Is it OK to use Home Theater Receiver ? Or will it damage my studio monitors? I'm very new to Studio Recording & I basically do it as a personal hobby, I don't have many buddies that play instruments. I simply play the conga's to a mp3 song & my girl adds voice when I can convince her.

    The biggest issue I see is that's a pretty lightweight amp.
    60 Watts into 4 ohms - that puts you at about 30 watts when you are driving 8 ohms. I'd at least double that.

    The powered version of those monitors drives them with 100W/side - that's a much better number to shoot for.

    Like Zemlin said more power. Its good to have a power amp that is at least 2x the power rating of the speakers for good clean sound and a long healthy speaker life.

    If this is for casual hobby work there is no reason you need to go for pro gear.

    sdevino & zemlin, So I can buy a home theater receiver with built-in DVD player and use it in my computer/studio room & also use that receiver to power my surround sound speakers in the living room? All I need to do is re-route the surround sound speaker cables to my computer/studio room.
    I'm going to start looking at crutchfield.com for a home theater receiver. I will double check with you guys before I buy it.

    Don't do this!
    Yes, you can use a home theater amp/receiver to power monitors, but please, don't get receiver with a built-in DVD player! There are no GOOD receivers that include DVD players built in and there is a good reason for that. Video circuitry adds a great deal of noise to analog amplifier circuits. Also, the receivers with built in DVD players are aimed at the mass market consumer who actually believes the "100 watts per channel" branded on the front. Truth is, that 100 watts per channel is rated at 1/10,000th of a second peak signal output. They are more along the lines of a 30 watt RMS system with barely enough current to deliver low frequency authority. (You see, as a speaker plays music in different frequency ranges, it's impedence changes. Studio monitors can have a very low impedence, particularly in the lower frequencies. If your home theater receiver can't effectively go below 4 ohms, you're in trouble.!)

    Please buy a quality receiver - this doesn't require THAT much extra money, but a mid-level Yamaha, Denon, Onkyo, or HK should be acceptable. Then spend the extra $49 to get yourself a DVD player that resides outside of the box! You won't regret it.

    "video circuitry adds noise" This makes sense.
    I'm still in the market for a studio amp, but I don't think I can afford a good one.

    Do you think a HAFLER TA 1600 will be good enough for my Samson Resolv56 ?

    I'm probably going to bid on this one

    Will this stereo 180w / channel AMP do the trick (yamaha natural sound r50 receiver)
    A buddy from my local aquarium club is selling it.

    Let me know before I make another mistake.

    Sure, the Hafler will work fine. You could use a bit more power, but overall, it's not a bad amp. I would be suspect though. It's a Florida unit and it's selling pretty cheap - it sounds like it got a bit wet from the hurricanes too.

    I'd shy away from the Yamaha - it's likely not rated for the actual power stated and the frequency response is probably no where near a linear 20-20,000 hz. A lot of these older units were only rated down to 40hz and distort badly below that.

    Stick with the Hafler. But hurry up, it closes in 20 minutes!

    Jeesus! someone way overbidded my bid.

    The Hafler TA 1600 should have no problem powering your Resolves. I use one with my 6.5" KRK Rokits, and I never need to crank the gain past 5. You can pick these up for $199 anyday at GC. A decent power amp is a very good investment.

    ...and, running long cables from room-to-room would also likely deteriorate the sound slightly. Having the amp in the same location as the Mixer and Speakers will GREATLY shorten the interconnects, and likely improve sound.

    I, too, would recommend on having a dedicated audio system for mixing. Then, become VERY familiar with it (listen to EVERYTHING you can as much as you can). Keep a CD player in the studio for such instances (run it through unused mixer inputs or mixer's efx returns).

    Hey guys, thanks for your advice, well finally I think I'm buy a Peavey 260H stage monitor amp. Accroding to the guy at daddy's junky music accross the street from Berkley school of music this amp willl work fine.
    I asked the engineers at work if they had a old stereo receiver laying around that they can sell me.
    Hopefully the peavey works fine.,

    I think that Peavey will have fairly poor low-end response, and likely not to quiet on the S/N.

    If you can afford the $200 Hafler, I really think you would be MUCH happier (and I sold Peavey for 5 years ;) )

    Thanks Randy, I have not heard anything negative about the HAFLER
    OH! I found the Daddy's in NY has a HAFLER DH200 for the same price as the funky peavey.
    Check it out?
    What is the difference between the Hafler ta160 and the DH200?
    Thanks again.

    Thanks for your help and advice. I found a Hafler Pro 2240 from a local pro-audio shop.
    Since they don't do much walk-ins they gave me a good deal on the hafler Pro 2240 $125. with a 30 day warranty.
    I plugged it in, I was a little confused with the chassis or float audio ground switch. But it is working, I can crank it up all the way and the sound is very clean (I mean crank it up all the way) The speakers are not as loud as I thought, but it sounds very crispy.
    Thanks again,
    Gilbert Gomez
