Connect avr to poweramp impedance

[Wookson]

Hi

I want to connect my avr to my poweramp

I ordered a double (stereo) cable to connect the left en right front speaker and a mono cable for teh center speaker .

Now i see the stereo cable has an impedance of 50 ohm, and the mono has 75 ohm...

Is this going to be a problem?

No. Impedance matching doesn't matter with audio interconnects.

50/75/110 Ohm impedance on copper cables virtually always refers to the Characteristic impedance, which only comes into play for digital signal tranmission at radio frequencies.

When used for analog audio transmission, the Characteristic impedance is irrelevant.

Indeed. Your average audio cable tends to be well in lumped element territory, so instead of characteristic impedance you'll mostly be interested in total cable capacitance. Which at 1 m is likely to be somewhere between 50 and 100 pF, so hardly much to lose sleep about.

OK, that is good news, thnx!
