Preamp drive level

[ahblaza]

Hey guys,
I plan on using my receiver's main pre-outs to drive a separate external stereo amp for my mains, can anyone tell me how to measure the preamp drive level of the receiver's preout. I'd like to know the Vrms my receiver is capable of driving it's preouts. I don't want to buy an amp and not know if the receiver's preamp can drive it to it's full rated power. I'd appreciate any advice with finding out how to measure this voltage. Thanks for your time.
Best.....

My advice is to look in the manual and see what it says about the preamp line output. Also, if you say what model it is, someone might happen to know about it.

That's good advice. I checked the manual for the Onkyo TX-SR702 yesterday, but I didn't see any listing for the preouts.

32dB gain structure

Just get a high gain structure amplifier like those offered by Emotiva…

Thanks guys,
I also checked manual and found no info, I also checked out some amps with higher gain (adjustable) inputs, Emo seems to fit the bill, but I'm still not sure. I've abanded the other receiver idea and go with a stereo amp or integrated? I'm leaning toward the integrated as a separate two channel stereo setup for my TT and CD player. My Onkyo seems to drive all channels with no strain in my 5.1 HT setup and has multi channel inputs I can use if and when I decide to go with a Blu Ray player with onboard decoding of audio formats and has multi-outs as well. I just have this upgrade itch as Adam so eloquently put it, and I feel like scratching it . Thanks my friends.
Best....Jeff

Hi. Another thing you can look for is output impedance of the preamp/receiver, and input impedance of the amplifier. Typically, 1:10 ratio is recommended (if not more), and some say that with tubed products, you might want 1:100 to avoid any possible tube hiss.

Good luck.
