Hi Wise men..........
Could you tell me somethin' more about the history of the use of 600
ohm lines in audio technology?????

To give you the right answer would be to ask why the telephone company
decided to make this their standard, as we got a lot of our standards
and practices from telephony. I don't know why they chose 600 ohms
other than that's what was what they made at the time.

It was the correct terminating impedance for the cross-sectional
dimensions of the long-distance overhead circuits they were already
using.
