I have been wanting to add a balanced line out to my SAE P102 preamp for years. During the rehab of the unit, I found the following in the manual for the SAE P101 preamp (P102 is unobtainable). I believe it means (though it does not directly say this) that I can create a balanced line out by using both MAIN OUT 1 and 2. MAIN OUT 1 is two rca jacks, one red one white. Same with MAIN OUT 2.
The manual basically says that MAIN OUT 2 is "out of phase (inverted)" with respect to MAIN OUT 1.
It sounds like I can take the MAIN OUT 1 "right" jack tip as "hot" in my balanced connection, take the MAIN OUT 2 "right" jack tip as "cold", join both grounds, and that's the three wires for my balanced XLR connection. Same for both "left" channels. Or is there something more to this? The rest of my rack (crossover and amps) are all balanced connections.
Here's the whole excerpt from the manual:
I'm hoping this infernal humming coming from my system. The preamp sounded so good on my bench, and now it's so clear, the hum when I put it in my rack is super annoying.
Thanks!
