Power amp /pre amp matching

Will a pre amp with an output impedance of 600 ohms match up with a power amp with an input imp. of 47,500? cant seem to find an answer in the archives,though I know I;ve seen it addressed before. Thanks in advance

Yes, it will be fine. Most people will look for a ratio of 20:1

Look through the amp/preamp archives for the specific reason why. I have read it several times myself.

I agree with Tom6897. Some will say a ratio as low as 10:1 will suffice, but the higher the better, and I recommend a minimum of 20:1. You are at 79:1, which should be no issue at all.

FYI Winoguy17,

for future use...
47,500/600 = 79.1
