Any normal preamp should be fine. A ratio of 1:10 is usually said to be the minimum. Most preamps have output impedances in the low 100's, though Ive seen a couple that get up close to 2kohms. Even those should be ok.
Preamp Output Impedance for my Amp
Folks,
I have a powermaster 2000 amplifier with the specs located here:
http://www.alphadigitaltech.com/pdf_files/PowerMaster%20specs.pdf
(It appears that input impedance is "25K + 25K"
What output impedance would be ideal for a preamp sending a signal to this amplifier? Also, what is the math required to find the answer?
Thanks for your help!
