hello : )
wondering if anyone has experience with audio and relays?
i am hoping to route audio via a mechanical relay ( DPDT) to switch between two inputs,routing one or the other input to a single out.
The audio is balanced ( hot cold + earth) i have two ideas in the pics below.
i would like to use just one relay to save money and space on the board.
I wonder if i need a resistor to terminate the input not in use to stop interference passing down the audio cables? ( perhaps i need to use two relays? as in the second picture? i hope this makes sense.
any help would be great. : )
