Pioneer THX Pre-Out Output Voltage

[Gov]

Supposedly all Pioneer THX receivers have the same output voltage, does this look right?

335mV/2.2kohm is for REC OUT terminals.
335mV input=>335mV output

For Pre out : output impedance is 490ohm.
output level for -20dBFs input , 0dB VR position => 150mV
-20dBFs input , +12dB VR Position(MAX) => 600mV
0dBFs input, 0dB VR position => 1.5V

This output level is determined by THX. (THX model is the same.)

My question is, will I be able to bring most amps to full power?

I don't think you'll have any problems...

I have 2 Pioneer receivers using the preamp out, and they work just as they were intended... All you need is to get the signal out to the amp, and the amp will do the rest of the work..

Yes, but I can't imagine why you would want to do that.

It is not that I want to do that, its just I want to know if my receiver as a pre/pro is capable of driving my LPA-1 to full power
I have entertained the thought of getting the UMC-1 when it comes out, even though, I really don't need it in my application. I would like something with better room correction capabilities. Not sure yet what the new Emotiva processors will be, but I am hoping it is like Audyssey.

If you are talking about pro amps then No you will not get full power. You will need an art cleanbox or a rolls mb15,which is what I use, to bring up the output voltage. I have a Pioneer and it made a world of difference once I put the rolls inline. Now with your amp I would contact the manufacturer and ask to make sure.
