typical audio impedances
After searching for a while on the internet, I must not be using the right search words but can't seem to find information on impedances. On a TV, what are the typical impedances for the rca audio outputs that typically go to an amplifier? What is the typical impedance for the output jack for earphones? Thanks. |

Thanks, although it didn't answer my question. I guess 2 seconds
wasn't enough. |

I searched with the correct spelling. I just mispelled it here.

Helps if you spell "impedence" right, to start with... But you just spelt impedance wrong ! Graham |

Typical output impedances of modern consumer audio equipment ranges from a few hundred to a few thousand ohms. (roughly 200~~2000 if you want numbers) Typical input impedances of modern consumer audio equipment ranges from several thousand to over 10000 ohms (5000~~20000 if you want numbers) Output impedances of headphone outputs is a mixed bag depending on whether you are talking about an MP3 player the size of your finger, to a large integrated amp or DVD player or something. Note that your questions seem wierd without some context. Modern consumer audio equipment is designed with low enough output impedances, and high enough input impedances that most people never have to even think about them. Which is likely why your web search was not very productive. Why do you ask? |
