It occurs to me that all you need is resistors in male/female adaptors. How's your soldering? You might start with 3 KOhm and see if that works. To give you an idea of the rating, P=V^2/R, so 1 watt would be more than enough. If you can find Vishay at 1% tolerance, you're cookin'. You can't get more direct than that without cutting into the IC's.
RCA requires only one resistor on the positive (inner). XLR needs two. If I'm remembering correctly, (it's been a while) terminals 2 and 3 are hot while 1 is ground.
