My guess is some of you know the trick of using a "fake-balanced" cable
to connect an unbalanced output to a balanced input.

I mean using a say 50 ohm series resistor to pin 2, another 50 ohm
resistor between pin 3 and ground, and pin 1 to ground.

A balanced cable can then be used to connect both ends, putting the
resistors in the unbalanced end. It would be something like this:

50R
RCA /^^^^^^----------o 2
| o-------------o 3
GND | o 1
|50R |
| GND
GND

As you can see, both hot and cold terminals "see" a 50 ohm resistor.

What I am not sure of is how far that trick can go in rejecting hum and
noise.
