Hi there!
I'm an electronics noob and want to verify I have done my research correctly before I destroy something. I need to sum analog line level signals together out of a mixing desk. The output is 50 ohms, max +21dB(U), balanced line level signal. After summing they go into a line level input. What I understood from my research is I have to put a 10k resistor (0.25w ok?) in series with both the + and - of both signals before joining the + of both and the - of both and the ground without anything in between. The loss should be -9.5dB, but if they are identical that should add 6dB so the total loss should in theory be between -9.5dB and -3.5dB.
Are these assertions correct?
** EDIT ** Also quite important, am I also correct if I say there is no (or barely any) loss of audio quality?
Thanks,
Chris
